List of Garo characters

This is a list of the various characters throughout the Japanese tokusatsu series "Garo", not including the Horrors, a breed of demonic beings that make for most of the series antagonists.
Garo the Golden Knight.
The various holders of the title are the main characters of the franchise, armed with the blade. The Garo title, based on the word for "hope" in the old Makai language, is traditionally associated with the Saezima family.
The one who takes the title of Garo is regarded to be the strongest knight, arguably since the said knight is intended to be the role model for his fellow knights. This is however, not a formal ranking in itself and no preferential treatment is given to the Knight, as evident with Kouga in "" who was in service for years before being promoted to be a Knight serving under the Senate. Regardless, the title nonetheless commands respect and even awe among the Knights, so much so that the symbols of Garo itself, a golden circle containing a red triangle and the use of a red scabbard, are instantly recognized by any Knight or Priest. To be in the presence of the Golden Knight is considered widely to be an honor, and it lends profound influence to the words of the Knight bearing the title. Even various Horrors, who are either ancient or notorious enough to be documented, also show knowledge of the Golden Knight's existence as well. The prestige that comes with the title means that the Makai community generally has high expectations for the one bearing the title of Garo, and as such often summoned whenever unusually powerful Horrors or those of legendary status appear.
Another Garo existed in an alternate universe where the last knight who donned it fought an impressive battle that results in the tarnishing of the armor from gold to black, and is put on display in that world's Tower of Heroic Spirits by Makai Priests. The armor eventually calls out to the priestess Hakana to restore its power. Hakana tries to perform a ritual to restore its radiance, only for the spell to be disrupted, creating the Madō Horrors that only her son Ryuga Dogai can kill as the new Golden Knight. Once the Madō Horrors are destroyed, the armor is fully restored and Ryuga is recognized as the true successor of the title of Garo.
In another alternate universe, the Garo armor has been without a holder for at least 20 years. Its most recent owner sacrificed his life to avert a dark calamity that strikes the world every 500 years. The armor ends up suspended high in the sky above the floating island of Shidōin in the Demon World with the Garoken embedded in stone below. Makai practitioners in this era once pit 100 Knights-to-be in a ritualistic fight to the death, with the last man standing being given the right to attempt to draw the Garoken and claim the armor. The Garo armor from this timeline appears more technologically advanced, featuring glowing blue accents and a more futuristic appearance. It is also able to absorb the inner darkness of humans around it, converting the energy into a substance known as Dark Metal. Once it has fully absorbed enough darkness, the Dark Metal stored within the Garo armor becomes the powerful dark armor known as the Veil.
Kouga Saezima.
 is the Garo of the first two seasons, a very unsociable person who always keeps his feelings to himself and puts up a deadpan face all the time, yet possesses a noble and kind heart. Kouga was raised almost without friends during his childhood and surrounded almost exclusively by people with Makai backgrounds, as such brought up to think little else other than slaying Horrors. His father was the one who started his training at an early age and he still trains on a daily basis to sharpen his skills. Since childhood, originally having a naive view of the world, Kouga was raised by his father Taiga whom he respected despite him not to associate with anyone besides Jabi, Amon, and Gonza while hunting Horrors. But after causing his father's death by who he thought was a Horror, a devastated Kouga is assured by Zaruba as he convey Taiga's final thoughts: Take the title of Garo and to be brave. He is assigned to the Eastern Region at the start of the series.
To that end, wanting to master use of Soul Metal, Kouga undergoes the path of becoming a Makai Knight like his father. Under the mandated alias of , which was placed so to protect the child's identity should he failed to graduate as a Makai Knight, Kouga befriended three other boys as they are all placed under the guidance of the Makai Knight Wataru. Though Kouga learned the value of friendship, he is forced to watch his friends being devoured by the Horror Raizon, keeping the beads they got from Wataru on his person in memory of them. Though he later trained under the Makai Knight Kengi, it still took over a decade since his father's death for Kouga to finally be strong enough to lift the Garoken from its resting place to become the current Golden Knight. By that time, Kouga reaches a conclusion of what he should fight for from his two teachers' ideal: one being that any person, good or bad, has not only the right to live, but also the potential to save many lives on their own in the process; the other being that one should try to his best to save another person, regardless of how slim the chances might be.
During the events of the first season, Garo meets Kaoru when he was slaying Anglay where she happened to be stained with Horror blood, a condition that will kill her in 100 days in an excruciatingly painful manner. Though expected to kill her to spare her a painful death, Kouga spared Kaoru's life because she reminded him of his mother. However, Kouga never told Kaoru about her situation and claimed to Zaruba and the Three Priestesses of the Eastern Watchdog that he kept her alive to be of use as a Horror bait. Eventually, saving Kaoru's life while falling in love with her, Kouga learns the truth of his father's death to be at the hands of the rogue Makai Knight Barago, who later kidnaps Kaoru to enact his plan to bring Messiah to the living world. While fighting a losing battle against he Priestesses' servant Kodama, who seemingly murdered Jabi, Kouga's refusal to discard his armor when the time limit was up caused his negative emotions to turn him into mindless while killing his opponent. After Zero saves him, Kouga battles Messiah and not only defeats her but Kiba as well, with the later at the cost of Zaruba. Some time later, Kouga is bidding an emotional farewell to Kaoru, as she would be heading to Italy to further her studies in art. She gave him the final product of her father's book with the last page painted, and Rei handed Kouga a restored Zaruba as a token of their friendship, which was reforged by the Western Watchdog. Though he still has his same old personality, he bears no past memories of his time with Taiga and Kouga, even stating that he didn't like the name Kouga gave him.
In ', Kouga was approached by Rin Yamagatana who delivered a message from Priest Amon. Kouga didn't believe her at first, but her mentioning their unfinished bar chess game persuaded him to take her seriously. Amon would return as a spirit to ask for his help to save Jabi's still-living body. Accepting the mission, despite interference from the resident Makai Knight Dan, Kouga enters the Makai Forest and battles the Makai Tree to regain Jabi. Soon after, Kouga receives new orders to contain the threat of the Horror Legules, managing to use the Phosphorus Arrow to destroy the fiend and his extensions. Soon after, Kouga returned home to find Kaoru painting in the backyard. They welcomed each other, clasped hands and walked back home, implying that they had finally confessed their feelings for each other. In ', on orders to destroy the Apostle Horror Karma, Kouga meets Kengi's daughter Rekka and helps her reach the same conclusion her father pointed him to years ago, as they work together to destroy the Horror. Parting, Rekka gives Kouga one of her young Makai Dragons, which Zaruba names "Kaoru" to Kouga's chagrin, that Kouga uses to search for Horrors while doubling as a messenger.
In ', Kouga gets promoted from his post in the northern region to serve the Senate for defeating the Apostle Horrors. But just after fighting the Horror Cigarein, Kouga is attacked by a mysterious red-masked man, who engraves a onto him. As a result, Kouga does not have much time to live and his life shortens every time he dons his armor, as well as suffering chest pains from time to time and his body gradually weakens over time. Hiding his condition from Kaoru, Kouga continues his duties as he investigate red-masked man before learning of his identity as Sigma Fudō whose plan to end the Horror menace with the power of Gyanon nearly sends the world into chaos. Though he defeats Sigma, revealed to be one of the friends thought to be devoured by Raizon, Kouga had to leave to honor the contract he made to Gajari to achieve his victory by traveling to the Promised Land to retrieve the Fang of Sorrow during the events of '.
Prior of the events of ", Kouga marries Kaoru and fathers a son, Raiga, but presumed dead after pursuing Kaoru into a vortex. However, during Raiga's inheritance ceremony, it is revealed that Kouga is still alive, fighting elsewhere in another world, and has relinquished his title as the Golden Knight so that his son may take up the role in his absence.
Kouga returns in " where he saves the time displaced Rekka and Rian and defeats Zaji once again. He heals Rekka's wounds and reveals to Rian that he is currently lost between dimensions and isn't physically with the two. Before he departs, he asks Rian to tell Rekka that he'll be back.
By the time of " and its mini-series prequel, Kaoru and Kouga finally reunite somewhere at Promised Land, but the-then animated Kiba Armor unexpectedly appears, possessed by Barago's surviving evil qi. It was after seemingly defeated Kiba she and her husband discovered that not only Eyrith being the one who separated her from her family, but also their son fight a losing battle against the legendary Horror, thus necessitating Kouga to send Zaruba to his son to aide him to become the next Garo. Kouga also revealed to have visited Tower of Heroic Spirits prior to his departure during which he learned that Raiga will form a deal with Gajari where the price would be carrying out the quest to mend all cracks of time and space Eyrith created one day, a quest he willingly take on his son's stead as well as how be found Kaoru to begin with. Upon learning that the recovered Kiba is after his son and possessed the late Shiroku to do so, he enlists aid from Taiga who soon assumed his pre-teenager form and alter-ego Baderu to prevent him from falling into their enemy's trap. Though the endeavor failed, the father and son reunited nevertheless shortly after Raiga overcomes Shiroku's trap in which Kouga tells the latter about his situation before being separated once again. Continuing their battle at Shiroku's fortress above the Tower of Heroic Spirits, Kouga is shocked to see his enemy's true identity and about to lose his ground until Raiga and Taiga appears to even the odds. Even so, Kiba soon turned the tide of the battle by combining his armor with Ouga that stored in the Tower by channeling heroic spirits he defeated only for the three generations of Garo bearers undo the upgrade and defeated him once and for all thanks to Mayuri and Kaoru sending them Garo Armor purified with their feelings of love and support. After the battle, Kouga departed to continue his mission, but not before reassuring his son that he will be back as he did 20 years prior.
As Garo, his armor helps protect him from damaging blows, but his armor isn't unbreakable. If a Horror is strong enough, they can damage and injure Kouga. Should the armor be exposed to a very powerful blow the armor will retract before the 99.9-second time limit. With the Garoken, transformed from Kouga's , Garo can cut down almost anything and only a rare few Horrors are strong enough to resist its force. Kouga is able to use a technique called . This is when he uses the Madō Fire from his Madō Lighter to encompass his sword and his armor to increase his damage potential. In some episodes, he's able to use Blazing Armament without the use of the Madō Lighter. When riding Gōten, his combat strength is increased with his Garoken transformed into the larger and the , the twice-sized Garo Zanbaken. Because his armor is composed of Soul Metal, the armor reacts to his will along with Madō Fire. The eyes of Kouga's Garo armor are green.
Kouga also received numerous powered-up forms in his many epic battles as Garo. During the fight with Messiah, the power within Kaoru's positive energy-based painting enabled Garo to become the angelic . Then, while fighting Legules, Garo uses the Phosphorus Arrow to negate the Horror's influence while turning into . And then, while fighting Karma, Garo becomes through the souls of the many Makai Knights she devoured over the years. While fighting Judam, Garo becomes through the energies within Kakashi's heart.

Ryuga Dougai.
 is the current Garo from an alternate universe parallel to that of Saejimas as of the events of '. Unlike usual Knights where armors are passed on from father to son or master to apprentice, the Garo armor was placed in the Tower of Heroic Spirits, and according to a caretaker monk, tarnished black after fighting a great battle long ago. Unlike his predecessors, Ryuga exudes a wild and imposing personality with a lack of respect for authority while he is actually kind and positive with a need to protect others, as well as an idiot who does not give up regardless of the odds stacking against him. Unlike the Golden Knights of the Saezima line, while he is brought up to be a formidable fighter, he is not as well educated and he is not proficient at all with the Makai language. He possesses the innate ability to hear people's feelings and thoughts by putting their belongings next to his ears. He uses the uncanny trait, inherited from his mother, as a means of sensing the presence of Horrors at times as well. Growing up as a child on an isolated island, he had always been fascinated with the Garo armor since his visit to the Tower of Heroic Spirits as a child, and promised his mother Hakana that he would be its wearer someday. Ryuga trained under Burai's instruction on the island for ten years with Ragō as his training partner before gaining the right to bear the Garo title. The eyes of his purified Garo armor are orange, though they are green while the armor is blackened. The armor also takes on a more fierce and somewhat sinister appearance before being purified, a weaker form known as the "Lost Shine" Garo (referred to as simply in merchandise). In ', Ryuga's Garo armor adopts an appearance similar to that of the "Lost Shine" Garo, albeit completely golden with orange eyes and somewhat different features, a form referred to as . The Garo Flight form is obtained after Ryuga temporarily lends the armor to the Makai Priestess Ryume for purification. What makes Garo Flight different from Garo's normal form other than appearance is unknown. Later, after facing his doubts while imprisoned in the Demon Mirror, Ryuga absorbs his inner darkness given form by the mirror to become , combining Ryuga's light and darkness with the ability to fly through the use of a bat wing-like cape, adopting a blackened appearance similar to the "Lost Shine" form. While Ryuga easily matches Jinga's Horror form in terms of sheer power, the Garo armor quickly regains its golden shine after Jinga's defeat. Ryuga later displays the ability to temporarily access the Garo Dark state at will by channeling both light and dark energies through the Garoken sword. While fighting Radan, Garo Flight becomes a giant version of it referred to as .
Though he killed Ragō to complete his training, Ryuga takes his training partner's fang as a keepsake and began a life of solitude after being told that his mother died during his training, resenting the Makai Priest for not being able to protect his mother. Not stationed in one place like Makai Knights usually are, Ryuga travels across Japan's cities to slay Horrors and erecting crude tombs overlooking them in memory of his mother. Eventually, Ryuga is sent to Vol City where he is reunited with Burai and reluctantly agrees to help him and the other Makai Knights stationed there. Finding himself facing Madō Horrors, Ryuga sees visions of his mother whenever hit by golden shock waves and emitted by the Madō Horrors' wounds that cause the Garo armor to momentarily regain its golden appearance as brief as the pain associated with it. While learning that they are behind the Horror residence of Vol City, Ryuga unwittingly gives the Kaneshiro Group enough evidence of his actions to create propaganda portraying him as a serial killer, and placing a bounty on his head. However, Ryuga resolves the matter by going through with an meticulously elaborated plan to confirm Rivera's identity as a Madō Horror, retrieve a piece of material off of her for developing a Madō Horror Detector while faking his death at the Vol TV station.
After his confrontation with Hyena, Ryuga makes a grave marker for his mother on the cliff overlooking the Vol City with Rian's help. Though his mind is racing with thoughts of Vol City and the mystery of his armor's connections to them, Ryuga reaches the conclusion that destroying the Madō Horrors is the only way to obtain answers. After the revelation that Tousei is responsible for the Horrors in Vol City, learning that he is human, Ryuga is once more portrayed as a terrorist along with the rest of his group. Though he evades Tousei's attempt to make him into a Madō Horror, Ryuga ends up being blinded by Sonshi with the Garoken thrown into the lobby of Tousei's office where it remained. Despite extremely unfavorable odds due to his blindness and placed in solitary confinement, Ryuga escapes the SG1 prison and with timely aid from his fellow Knights, retrieves the Garoken. Soon after, finally acknowledged by Zaruba as they form a contract, Ryuga is reunited with his mother and learns that she was used by Tousei to sire Madō Horrors who are revealed to hold her memories. After Hakana gives up her own eyesight to restore his, Ryuga races off to the Hill of Zedom's Arm to save Rian, and finally kill Enhou through the combined efforts of him and Rian. After killing Enhou, hearing the last trances of the woman's humanity through her necklace, Ryuga vows to never have another innocent be sired as a Madō Horror.
In a bid to stop Zedom's resurrection, the group head for the slowly crumbling Hill of Zedom's Head and Ryuga knows right from the start that Burai intends to sacrifice himself. He eventually thanks Burai for all the priest has done for him, before heading to fight Sonshi and defeating him with the aid of his friends. With the Garo armor finally regains its brilliance, forced to kill his mother to spare her from becoming a Horror, Ryuga battles Zedom. During the fight, as the Horror attempts to consume him, Ryuga tells Zedom that the eyes he gained from his mother are a symbol of hope and future before he and the Makai Knights destroy him. With Vol City saved, Ryuga parts ways with his friends to not only build a grave marker for his mother in the Makai Priest ruins, but also deal with Tousei since he is now a Horror. After Rian kills Tousei in his stead, Ryuga accepts her request for her to join him in his southward journey.
In the events of "", Ryuga returns sporting his old gear, unlike his other two Makai Knight associates back in Vol City who sport entirely new sets of gear. Ryuga and Rian are given orders by Ryume to look into the Horror incidents happening recently, before becoming the third and last victim, after Aguri and Takeru, of Banbi's scheme of stealing Makai Knight armors to temporarily resurrect his dead lover and fallen Makai Knight, Judo Tenma, thus forcing him to inadvertently pursuing his original objectives for totally different reasons. In the midst of his investigation, Ryuga met his old, slain archenemy from "Garo: Gold Storm Sho", Jinga, after Banbi got tricked into resurrecting Jinga instead of Judo. Ryuga, Rian, Aguri and Takeru pursue Jinga and Rinza as the Fang of God was being created and activated. He ultimately stops the full on activation of the Fang of God by slaying Jinga yet again, thus prevent the summoning of Messiah, the progenitor of Horrors, into the world.

Raiga Saezima.
 is the holder of the title Garo during the events of "", assigned the Blue Region. He is the son of Kouga Saezima and Kaoru Mitsuki, who mysteriously disappeared when he was six and assumed they were dead. Regardless, Raiga continued training even in the absence of a mentor when he was young before Rei Suzumura took the boy out on his first night of Horror hunting. Unlike most children from Makai families who are decided from birth by their parents to walk the Makai path, Rei allowed Raiga to decide for himself if he wants to be a Makai Knight, who eventually decided to succeed his father as a Makai Knight and became the Silver Fang Knight's apprentice, after a passing a trial on the night before his birthday. Raiga eventually succeeds his father as the Golden Knight Garo, learning during the ceremony for his inheritance of the Garo armor that Kouga is still alive and fighting in another world. With his father's permission circumventing their ancestors' initial decision, Raiga is given the title and armor of the Golden Knight.
Raiga is more easy-going and sociable compared to his father, often quipped by Gonza that he would probably be the kindest Knight around. He was quite an accomplished fighter even at a young age, seen capable of pulling off tricky moves when he sparred with his would-be mentor. He has a sharp wit and is already quite perceptive at the age of ten, even with the lack of formal tutelage. Under the later tutelage of Rei, Raiga fights in a noticeably different style that is more fluid and precise, yet flashy and less aggressive. His swordsmanship also surpasses that his father's, capable of drawing and sheathing his blade repeatedly in stylish manners without looking, even during battle. He is seen often fighting with both his sword and scabbard, an influence from Rei's dual-wield fighting style. Unlike his father, he prefers to toy around with his opponent barehanded before drawing his blade if the situation is not serious enough, and even after doing so, prefers to remain defensive and gauge his opponent before going into offense. He is usually a gentle person and rarely gets angry about anything, be it in or out of battle. However, when he does get angry in battle, his fighting style changes dramatically, where subtlety is non-existent and moves are heavy-handed and straightforward with a single-minded intention to pummel his opponent. While the Garo armor he dons is the one donned by all Golden Knights who came before him, Raiga can however use unconventional features of the armor, such as conjure flames from the armor at will and use harpoon blades at the back of the armor. The eyes of his armor are blue. While fighting Eyrith, Garo becomes after taking control of his armor even after it possesses his body once the time limit expired.
During his fight with Zaji, he earned the right to summon Gōten despite not having undergone the same trial as his father. The reason of such, as stated by the spirit of Garo, is that by fighting Zaji, he is essentially fighting his own darkness.
Like his mother, he smiles a lot and is interested in drawing. However, based on Mayuri's comments on his artwork, he might not have inherited Kaoru's talent as well.
Raiga Saezima is portrayed by . As a child, he is portrayed by in "Garo: Makai no Hana" and in "Garo: Ashura".
Gouki.
 is the holder of the Garo title during the events of "Garo: Ashura", a story that takes place in the distant past and predates the creation of Madōgu like Zaruba. Unlike modern holders of the title, who wield a smaller jian-like sword when unarmored, Gouki's Makai Sword is a large chunk of roughly-shaped Soul Metal about the same size as the Garoken sword in his armored form. Empowered by the feelings of his new friends Ren, Shin, and Taku during a battle with the powerful Horror Zarugin, Gouki's armor takes on the winged , allowing him to defeat the Horror with a powerful High Fly Flow from the sky. The eyes of his Garo armor are silver.

Rei Suzumura/Zero the Silver Fanged Knight.
/, once known as , is a rival turned anti-heroic ally of the series and the Silver Makai Knight of the West. He was an orphan before he was found by Douji, who took pity on him and raised Rei as his son to inherit his position as a knight of the West and start his own lineage. Though trained as a Makai Knight, Rei didn't have the tenacity or murderous intent to be a true warrior. One fateful night, however, Shizuka and Douji were both killed by a warrior who suspiciously resembled the Golden Knight. After giving his dead loved ones proper burials, He renamed himself Rei, putting his old name before his Knight title, and naming his armor 'Zero', with both names being a pun on "Zero," with intention to reinvent himself as well as to get back at the Makai Knight that took his loved ones away, becoming a person full of angst, wild and murderous.
During Zero's quest for revenge he violated a host of protocols expected of a Makai Knight, from leaving his western territory post to directly attack Kouga. Though his investigations lead him to Kouga, Zero wasn't sure if Kouga was actually the knight that had murdered his family, thus he remained constantly uncooperative with the Golden Knight and even started fights with him to vent out his anger. Later in the series, the Watchdogs of the East try to frame Kouga for his family's death; Zero would later discover the true killer was Barago and ally himself with Garo. As the truths of matters unfold, his personality drastically changed, becoming more like his old self. He became more relaxed and open, turning into a caring friend for Kouga as they now share the same enemy. Rei and Kouga later visited the Western Watchdog where they reported and were ordered to assassinate Barago and Gulm. Because of Zero's tall list of violations he wasn't allowed to participate in Kouga's mission, but Kouga argued on his behalf, saying that he need his power. Rei's suspension was relinquished and he joined Kouga in dealing with Barago and Gulm.
During Kouga's dark transformation, it was Zero who helped Kouga snap out of his darkness. Gulm tried to stop the duo from reaching Kiba and Kaoru, but Rei decided to stay behind to deal with her, allowing Kouga to press forward. She assumed Shizuka's form and tried to trick him. He soon saw through her illusion because the real Shizuka addressed Rei as Ginga, while the impostor constantly called him Zero. After a very difficult fight Zero almost died, but survived a mortal blow because Silva took the hit. After a losing fight against Gulm, he took the opportunity of her overconfident victory and killed her. After Kiba's defeat, Rei presented Kouga with a reforged Zaruba as proof of their friendship and remained in the Eastern district to protect it while Kouga went northward.
In ", Rei was assigned to help guard the upcoming Kantai ceremony from Horrors' attack. He saved Hyuga and Akatsuki, Tsubasa's disciples, from Karakuri Horrors. After aiding Kouga and Tsubasa in their fight against Legules, he returns to his district.
Rei resurfaces during the events of ', having been afflicted with the Seal of Destruction and in a weakened state, though he acts unconcerned and continues his duties, much like Kouga himself. Although friendly and personable, Rei admits to Silva that he dislikes large groups, once turning down an invitation for dinner at the Saezima Estate. Later, from his confrontation with Juzo Igari, Rei considers settling a few matters with Kouga over which of them is the strongest, which he does by the end of ', although the outcome is unknown. He also meets an old friend named Misao Hoshikawa, forced to make her hate him by killing the Horror that possessed her mother's body.
Rei's personality and lifestyle are further explored in ". It is revealed that aside from past allies such as Kouga and Tsubasa, he has few friends and spends most of his time lazing around when he is not out hunting Horrors, with Silva being his only company most of the time. Despite being a friendly and laid-back person, he dislikes having to work with others, often running off to do his job alone regardless of his partners' opinions. He lives in a small apartment in a seemingly abandoned building, having few material possessions beyond his motorcycle. He is also revealed to have a strong sweet tooth, adding excessive amounts of sugar, cream, honey, or anything sweet in anything he eats or drinks. His sweet tooth tendencies annoy the bartender Bakura, who often tells him to just get ice cream instead of asking for more cream in cocktails.
An older Rei appears in ", becoming Raiga Saezima's mentor when the child was ten years old upon Kouga's request. He tested Raiga's martial skills and, confirming Raiga to be fit enough to begin training under his wing, took Raiga out the night before the child's birthday to go Horror hunting, to show the child what Horrors are like firsthand and confirmed Raiga's wish to walk the Makai path. After completing Raiga's training, he also departs on a journey like Kouga did, claiming to Gonza that they will eventually return home safely.
Zero wields a pair of short swords called the . In their Makai Sword form, these are shorter versions of Kouga's Makai Sword, which he typically holds in a reverse grip by default, and oddly, around the guard instead of the hilt. When Zero dons his armor, the swords become curved scimitar-like blades. These can be locked together to form a larger crescent-shaped double-bladed boomerang called the . Zero's armor can launch hooked wires from the emblems on his chest near his shoulders, which he can use to snare opponents or anchor himself to surfaces. His Ginroken in their Makai Sword form can similarly launch their blades from the hilt attached to wires. In ", Rei exceeds his armor's time limit and becomes during his final battle with Edel. The armor is further warped into dragon-like during the fight, becoming capable of flight. Zero's Madō Horse, Ginga, is similar to Garo's Gōten, but with a blade attached to his head. Rei claims that he is immune to all poisons, though it is unclear if the trait is unique to him or if all Makai Knights possess a similar immunity.

Tsubasa Yamagatana/Dan the Midnight Sun Knight.
/ is the White Makai Knight of Kantai, introduced in "". The Yamagatana family is a family of Makai Priests, but he converted to a Makai Knight after his parents' death. His parents, both Makai Priests, died in combat with Horrors and thus takes it upon himself to oversee the well-being of his younger sister Rin. He is a strict and "by the book" type of guy, believing that emotions will only get in the way of his duties and that both a Makai Knight and those dear to him must be prepared for the former's demise. Tsubasa also has a pair of disciples, Hyuga and Akatsuki, under him. Not notified of Kouga's arrival to Kantai, Tsubasa confronts the Makai Knight after he defended his disciples and fight him before Garai intervened and told Tsubasa to let Kouga pass to carry out his mission to save Jabi. Tsubasa objected to what he thought was an act against natural order and originally saw Jabi as an abomination until she risked her life to save Rin. After he apologized to Jabi for his rudeness towards her, Tsubasa joins her with Kouga and Rei to defeat Legules in the Abyss Forest. After Legules' defeat, Tsubasa told Rin that she's his pride and finally showed his smile when Rin performed magic to create butterflies.
During the events of ', Tsubasa is revealed to have been marked with the Seal Destruction as well, his condition far worse than Kouga's and Rei's due to far more frequent summonings of his armor, suffering intense pain on his chest all the time. He intends to get rid of Wataru, assuming that he had fallen completely to darkness. Even when rectified by Hyuga and Kouga later, he stands his ground as he sees that to be the only way to free Wataru from his suffering. However, touched by Kouga's actions and thoughts of wanting to save the suffering knight from his inner darkness even though chances might be slim, he ended up helping Kouga save Wataru from himself nonetheless, allowing himself to be stabbed together with Wataru to pin Wataru down so as to purge the evil influence within Wataru's armor. Tsubasa assures Kouga that he has no intention of dying at the moment, and promises Kouga that he would not harbor the intentions of throwing his life away easily because of his condition as he did previously. In ', it is shown that Tsubasa and Jabi frequently work together and it is implied that they share romantic feelings.
As a Makai Knight, other possessing great fighting skills and amazing speed, he possess traits unusual for a Makai Knight, wearing a jacket over his shirt and skirting on his lower body, which is more common with Makai Priests, rather than a duster like other Knights; he also augments magic into his fighting style through the use of his special earring. He wields a bō/spear called which has a spearhead tip that can extend out by section being twisted. Donning his Makai armor, the very aura it produces able to disintegrate a Horror, Dan is armed with the double-headed and uses a purplish Madō Fire.

/ is a Makai Knight serving the Senate, donning a suit of azure armor similar in style to Bado's and wields the , a scimitar-like sword, in his armored form. As one of the Makai Knight instructors training young Makai Knights-to-be in his earlier days, Wataru gains infamy for his draconian yet effective methods. Despite his gruff demeanor, he actually cares deeply for his pupils. He considers the bloodline of a student's Makai Knight family to be of no importance, instead focusing on if the person in question has the strength to protect others, and that one should try his or her best even though chances might be slim. Wataru happened to have Kouga under his tutelage while a boy, playing a vital role in helping to foster the youth into who he is now. Sent on a mission to find the red-masked man, Wataru is ambushed by the villain as he marks him with the seal of destruction, causing his inner darkness to awaken. Being almost completely taken over by his dark side, Wataru is forced to attack his fellow Makai Knights as he attempts to keep himself at bay. He tried to kill himself to avoid being taken over completely by the darkness within him, only to be stopped by his evil side. Eventually, Kouga and Tsubasa manage to purge the evil influence from his armor and returning him to normal. While telling Kouga of the possible tension between the knights and the priests that can be caused by the Sigma Fudō's actions, Wataru recognizes him as his pupil. Wanting to return Kouga's favor of rescuing him earlier, he joins the final fight with Gyanon.
In ", it is revealed that he has a dark sense of humor and enjoys toying with Horrors he hunts. Being sent on missions to wipe out small pockets of Horror communities, his modus operandi is to act as a bait to be captured and caged as livestock in their hideouts, later emerging and slaying the entire house when he deems the time is right. As these hideouts tend to be dilapidated bars, he usually also orders a drink from the Horror bartender after slaying all other Horrors, granting a quick death if the drink tastes good, and chopping up said bartender piece by piece if the drink tastes bad.

Aguri Kusugami/Gai the Sky Bow Knight.
 is latest in his line to inherit the title of , who secretly worries that he cannot live up to his family's prestige. His family is known for skills in archery and as noted by Ryuga, being able shoot arrows continuously and rapidly is one of the basics of the Kusugami Style Archery Techniques. Although his combat skills lies predominantly in archery, like any other Knights, he is capable of fighting in closed quarters. As such, he wields a large bladed which also serves as a closed quarter weapon. He does not see much in Ryuga and initially adopts a rather antagonistic attitude towards the newcomer. Cool-headed and standoffish, Aguri favors careful and meticulous planning over rushing into battles like the knights are usually known for, and he does not mind using unwilling people as bait if it means getting the job done. As such, despite being the brains of the group, he does not mingle well with the other two knights and often comes into clashes with them. After Takeru mellows down due to affection for Rui and Ryuga showing kindness over time, he gradually warms up to both of them. Despite seemingly stoic-looking, he is not devoid of compassion, shown during a mission in the Kaneshiro Foods Factory (which has a plant for packaging human souls into capsules) where he opts to trigger the emergency alarm to have the human staffs evacuated, despite the possibility of jeopardizing the mission due to SG1 arriving in minutes, after being shown the lives devastated in the harvesting of human souls. While he is shown earlier to be unable to shoot arrows capable of piercing through Madō Horrors, he eventually becomes skilled enough through rigorous training to be able to accomplish the feat.
After the disastrous mission and hearing of Ryuga prison break, he correctly predicts that Ryuga would head straight for the Garoken despite unfavorable odds. He promptly sets out to Ryuga's aid despite the group being in no shape to fight after their last ordeal. His bow is broken by Sonshi in the fight to help Ryuga get his sword back. The bow is repaired soon after, but is now capable of being separated in the middle and used as a nunchaku as well as a pair of swords. Aguri also receives a special arrowhead from Burai that enables him to further weaken Zedom during the final battle. Once Vol City is saved, Aguri parts ways with his friends to join the Senate. However, wanting to hone his skills further before going, Aguri takes over Rian's duty as Vol City's protector so she can travel with Ryuga.
In the events of ", Aguri returns wielding a bow-styled Makai blade which can be transformed into a bō, using collapsible metal arrows, as well as wearing a black duster instead of his old blue one. Events of the movie unfold as he lends his armor to a childhood friend, Banbi, to temporarily resurrect her old fallen Makai Knight lover, Judo Tenma, only to have her running away with his armor and searching for more Makai Knight armors after finding out that one set is inadequate to perform the deed. Inadvertently roping in Takeru and Ryuga as their armors got taken from them forcibly by Banbi as well, he ultimately helps to stop the full on activation of the Fang of God, thus prevent the summoning of Messiah, the progenitor of Horrors, into the world. They part ways again after the ordeal.

Takeru Jakuzure/Zen the Flame Sword Knight.
 is a laid-back, self-styled playboy who prefers going after girls over hunting Horrors. As , Takeru wields a liuyedao and although laid-back, he is nevertheless skilled in combat. Unlike Aguri, he takes an instant liking to Ryuga and finds him interesting, despite Ryuga being standoffish during their first meeting and seeing the rest of the gang as little more than nuisance. However, despite their rough introduction, both Ryuga and Takeru get along well quickly. His playboy attitude changes drastically after meeting Rui, as he abandons his womanizing ways completely and dedicates most of his time to look out for Rui, often seen hanging out at the flower shop where she works, prioritizing her over his duties as a Makai Knight. During the confrontation with Tousei, Takeru saves Ryuga from being turned into a Madō Horror with the Madō Horror Plant stabbed into his right hand. To prevent the roots from spreading and turning him into a Madō Horror, Takeru forcibly cuts off his infected right hand which he has Ryuga destroy. Although he falls into a depression soon after, Takeru regains his resolve and promptly sets out to Ryuga's aid with Aguri. He eventually gains a Soul Metal fist created by Burai to replace his lost hand, which can be turned into a shield at a moment's notice without having to summon his armor, although he has yet to develop fine control of the fist to enable him to use it as a normal hand, reducing his effectiveness with a blade somewhat, but still potent in battle nonetheless. Once Vol City is saved, Takeru parts ways with his friends and heads west. Meeting Rui one last time before leaving Vol City, Takeru vows to become a better man and be more serious.
In the events of "", he wields a Bowie knife-styled Makai Sword which can be lengthened into a dao-like longsword, replaces his old red and black garb with an all-black one, and now has fine control over his Soul Metal Fist to use it as a regular normal hand. His hair has also lengthened considerably, yet he is still the same jokester who throws inappropriate, lewd jokes every so often. He got roped into the events of the movie after having his armor stolen by Banbi, and ultimately teams up with Ryuga, Rian and Aguri to stop the full on activation of Fang of God, preventing the summoning of Messiah, the progenitor of Horrors, into the world. They part ways again after the ordeal, but not before telling Ryuga and Rian to give him a call, should both of them made a baby.

Crow the Phantom Knight.
 is a Shadowfolk Makai Knight who is serving in the White region and is sent to assist Raiga, as the museum where the slate was unraveled is within his jurisdiction. While he is also easy-going, unlike Raiga, he is rather aloof and rarely seen smiling. However, he respects status and authority, shown to apologize to Raiga immediately after learning the Golden Knight's identity for speaking in a cheeky manner earlier. He is armed with a ninjatō-styled Makai Sword and shuriken-like weapons called the , which also serve as trackers and extensions for Horror detection with the help of Orva. His real name, if he even has one, is never revealed as, according to Orva, a Makai Knight who lives in the shadows does not need a true name. Like his title's namesake and black-ops image, Crow's armor is midnight blue in color and is less ornate than most Knights. While donning his armor, Crow wields the . The most notable feature of Crow's armor is its capability of sprouting wings for flight, although he sacrifices twenty seconds of use of the armor to summon them. Due to the inherent risk of his armor lifting during aerial combat and causing him to fall to his death, he rarely uses this ability. The "wolf ears" on his helmet are capable of folding downwards to serve as a visor when in flight. His tasks are more strictly defined than most Makai Knights - locate and destroy Inga Gates during the day and hunt Horrors at night without anyone's knowledge. Whether this is a self-defined role, the traditional role of the Phantom Knight, or a modus operandi shared by all Shadowfolks is currently unknown.
In ', he is seen visiting his former mentor, Eiji, now imprisoned by the Makai Order for the crimes committed by releasing Eyrith. He pretended to ask for a duel to the death in the mental realm so as to face up to his weakness, and ended up defeating Eiji. In actuality however, that was just a ruse so that he can enter Eiji's mind and help cut down his former mentor's inner darkness. Despite all Eiji put him through during the events in ', he vows nonetheless to one day fight alongside Eiji again.

Daigo Akizuki/Giga the Beast Knight.
 is a Makai Knight who is also in charge of training young Makai Knights-to-be and holds the title of a . He is a proud, stoic, cautious person who always properly weighs odds before doing something. Daigo holds the belief that Makai Knights should be more mindful and protective of their own lives and weapons, as their blades are tied to their lives, which are tied to the protection and salvation of innocent lives--a belief he teaches to all his students. His teaching methods are also fairly harsh and he will not hesitate to criticize and scold his students for minor mistakes, especially dropping or mishandling one's sword. Unlike many Makai Knights shown throughout the series who care little for their own social status, Daigo puts a lot of weight in seniority, rank and authority, both his and that of others. He also tends to address people with their surnames instead of given names, an uncharacteristic trait within the Makai Order. As such, he refuses to "take orders" from his juniors unless absolutely necessary and demands respect and tact from those he deems lower than himself, only regarding someone if they address him with the proper decorum befitting his position. Ryuga, known for his recklessness and general disregard for authority, is a complete antithesis to Daigo. As such, Daigo is very disapproving of Ryuga's methods and way of life, while Ryuga finds his imposing presence irritating, thus resulting in their relationship being an uneasy one. Daigo also holds some distaste for Gald, as the boy's rude, informal, and disdainful attitude, especially towards Makai Knights, infuriates him. Despite his distaste for Gald, Daigo eventually develops a soft spot for Haruna, going as far as to keep an eye on her as a gym teacher at her school when she decides to temporarily enter normal life in "Garo: Makai Retsuden".
In battle, Daigo wields a . As , Daigo dons a suit of bulky green armor with bestial characteristics and wields the two-handed that he uses to unleash devastating blows, capable of killing dozens of low-level Horrors in one swing. He is also equipped with a large claw weapon mounted on the left arm, which he uses when his axe is otherwise unavailable. Daigo also displays the ability to grow the Jushinfu to a great size and propel himself forwards to unleash a powerful charging attack.

Jinga Mikage/Roze the Glittering Shadow Knight.
 is a Makai Knight and the protagonist of ". Mikage is actually the reincarnation of Ryuga Dougai's nemesis, a fallen Makai Knight-turned-Horror named Jinga who was destroyed by the Horror Messiah when he challenged her. He was born within the Mikage family and became an established Knight at a fairly young age, forced to kill his own father after he was possessed by a Horror and killed his mother. Mikage is since haunted by the event, his Makai Priestess partner Fuusa noticing his emotional trauma when it comes to the subjects of family and parents. Despite often sporting a tired nonchalant look, Mikage is faithful and caring towards Toma and Fusa in his own way while taking an aloof and indifferent approach to just about anyone or anything outside of slaying Horrors. But he is shown to have faith in humanity as he believes no human is destined to become a Horror, no matter how evil they might be. Following his mission of slaying the Horror Cadena, his right hand is bitten by the Horror with a slow healing wound noted by Toma to look like a wolf's fang, Mikage inexplicably gains the unprecedented ability of seemingly exorcising Horrors from their human hosts at the cost being unable to seal a Horror's essence in his blade.
Soon after, Mikage develops a strange feeling of being watched as a strange butterfly remained by his side during one unusual night when a large group of Horrors appear in multiple places. He meets Rozan and Shijo, who were tracking him down after learning of his powers. While their meeting proceeds amicably, the dark Jinga of his past life briefly manifests himself and killed Shijo in secret with Rozan keeping an eye on Mikage. Soon after, Jinga becomes haunted by his past self who chastises him for keeping to the Makai Knight mission and avoiding the darker aspects that his powers offer. The resulting battle from the 'introduction' ends inconclusively, with Jinga deciding to fall back to the shadows for now and observe his reincarnated self's actions while influencing him to murder Kaname and his son Subaru under the pretense of requesting a friendly match. 
In time, Mikage's abilities cause him to develop a messiah complex and paranoia that result with him going on the run when Kerus requests him to submit himself for further inspection of his powers, joined by Toma and Fusa before the former turned himself in. Mikage also murdered Fusa when she attempted to talk him into surrendering himself at Toma's behest. Mikage is then confronted by Jinga, who reveals the truth of their power——it only suppresses the possessing Horrors rather than exorcizing them. Mikage refuses to accept the truth that he had endangered more lives than saved until he is attacked by a furious Toma who consciously awakened his Horror form. This revelation destroys Mikage, rendering him despondent as Jinga metaphysically kills him off to complete his resurrection.
As , Mikage dons a set of steel-gray and crimson armor that resembles his past life's Horror form, which itself has been a corruption of his original armor. In his armored form, he wields a jian-like blade and specializes in rapid, aggressive attacks.

He trained Yuna to fight from a young age, something Iyu was not so happy about. When Iyu presumably perished, he took care of Yuna on her own and presumably without giving her further training on Makai magic. On the night where he and Kain are supposedly off to fight Ring for the last time, Iyu showed up unexpectedly beside Ring. Shaken and confused, he prevented Kain from landing a hit on Ring which can potentially get Iyu in the crossfire, a chance Ring used to deal a fatal blow to him, before throwing another that severed his arm holding his sword.

Despite refusing help and being gravely injured during the fight, Seiji manages to get his revenge with Ryuga and Daigo's support before Woska's remains are consumed by Jinga and Amily. When Jinga and Amily proceed to mock him by calling late students animal feed, Seiji ends up being promptly killed by the cannibal Horrors in an attempt to kill them for disrespecting his students.

Rozan.
 is a veteran Makai Knight who comes from a family of Makai Knights. He is one of the few knights who wield polearms, in his case, a spear, instead of a sword. He is tasked to investigate the rumors of a Makai Knight capable of exorcising Horrors from humans, taking Shijo, a subordinate of his along. He is shown to be a strict, no-nonsense person, exuding an intimidating and imposing aura. However, he is open-minded and cares about humanity, shown as how unlike Shijo who is insistent that such a feat cannot be accomplished, Rozan opts to keep an open mind and consider the possibility of such a person existing, however unlikely it may be, often quipping that how such a feat will change the Makai community for the better. He is experienced investigator and sports a sharp wit, capable of taking minute clues out of scenes of battle and deducing what took place there vividly, allowing him to create a rough profile of Jinga before meeting the rumored Knight in person. While pleased to actually meeting Jinga and confirming the rumored Knight's never-before-heard-nor-seen abilities, he remains cautious of the possible harmful or unwanted effects of such an ability, electing to keep Shijo around Jinga to keep an eye out on things.
Rozan is portrayed by .
Shijo.
 is a Makai Knight who serves under Rozan. While he is shown to be an accomplished knight capable of wielding a Soul Metal blade, it is implied that he has yet to acquire his own title and armor. He is dressed in notably different manner compared to other Knights, with his coat being a yellow one with brown accents, worn buttoned up, and shown to be wearing little to no black--the traditional dress color associated with the Makai community. He is taken along by Rozan to investigate the peculiar case of a Makai Knight capable of exorcising Horrors. Initially skeptical and insistent in his belief that such a feat cannot be possible, he changes his mind and quickly becomes excited and curious about Jinga's powers after seeing Jinga in action. He is left to be at Jinga's side by Rozan, presumably to keep an eye on the peculiar Knight. He is soon asked by Jinga to tag along in his investigation of the reason behind the abnormal number of Horrors appearing in just one single night. While thanking Jinga wholeheartedly for being given such an unusual opportunity when both are alone out in the night, he is surprisingly and inexplicably killed by Jinga while briefly possessed by his past life.

Madōgu.
Although the term "Madōgu" generally refers to all Madō tools, in some context, the term is specifically used to refer to sentient accessory items that serve Makai Knights by providing advice and a vast array of magical powers.
In the franchise's second continuity which centers about Ryuga Dougai instead of Saezima family, Madōgu are more or less treated as relics from a bygone era by the events of "" and became very rare with most Makai Knights no longer carry them. This is likely motivated by the fact that unlike in Saezima's continuity, such ancient tools require a contract with its user in exchange for shortening their life. This includes said continuity's Zaruba, which consumes one day of Garo's life for each month their contract lasts as a price of providing his services, shortening the Golden Knight's lifespan.
Zaruba.
, named after the old Makai word for "friend", is a Madō Ring who has existed as long as the Garo title had. Thus, serving the bearers of the Garo title for generations, Zaruba has been the only character that appeared in all entries of the Garo series with exception of "Versus Road". As a Madōgu, the criteria in forming a pact between him and his Golden Knight vary; whereas in Original Series Zaruba briefly puts his new owner into horrifying illusions to show the extent of horrifying things he would possibly face as a Makai Knight, Ryuga Dougai-centered continuity instead takes one day of his life once a month during a new moon. Regardless, his role is to detect Horrors while providing advice and combat strategies. In contrast to some of his owners' more deadpan and silent personalities, Zaruba is very talkative and cheeky, and does not hesitate to make fun of his master as well as those nearby, and would bicker with his master if he feels like it. But like all Madōgu, he is sincere and faithful, sometimes even serious, when it comes to getting the job done.
In Original Series, Zaruba is stated to be created by the veteran Makai Priest Amon, and originally owned by Taiga Saezima before coming into the possession of Kouga. During Kouga's final fight against Kiba, who magically sealed the Makai Knight's ability to summon his armor, Zaruba apparently used all of his energy to merge the power of all the past Garo knights into the armor temporarily and manually bring it to Kouga. This results in Zaruba's physical form crumbling, though the ring is restored by the Western Watchdog with Zaruba devoid of his memories while returned to Kouga as he continued to serve him and his son Raiga, his eye color having changed from black to dark red.
During the events of "Garo: Yami o Terasu Mono" of Ryuga Dougai-centered continuity, Zaruba ends up in Burai's care before being given to the current Garo: Ryuga Dougai. While Zaruba deemed Ryuga too immature to worth speaking to, witnessing the young Makai Knight's resolve while blinded convinced him that the human is worthy to forge a contract with. From "" onward, Zaruba has a visor that Ryume attaches to him, enabling him to summon a portal out of any wall, allowing Ryuga and Rian get to Ryume's place from virtually anywhere. Hilariously, Zaruba is unable to speak while the visor is closed and will make a ringing noise to signal that he has something to say, a trait which Ryuga uses to shut Zaruba up if he deems the Madō Ring to be too noisy. Unlike his counterpart which in the possession of Saejima family, Ryuga Dougai-centered continuity iteration of Zaruba is more no-nonsense and speaks only when he needs to despite occasionally make jabs at Ryuga.
The full extent of Zaruba's abilities and knowledge is unknown; Original Series established him being able to help dispel confusion, detect various spiritual energies, summon the Garoken, speak on behalf of the dead, enable temporary flight to his wearer, breathe Madō Fire (in the Crimson Forest), detect Horrors, create parts of himself into a ring to acts as an transceiver, see through illusions, converse with Kouga telepathically, act as a temporary storage for miniature items, and gauge power of items. He helped train Kouga when Kouga was still a child after Taiga's death. He has since advised him on a variety of matters and even taught Kouga how to play Poker. His aid is not limited to Makai Knights — Kaoru once used Zaruba to guide her through the Crimson Forest back to the human world. His illusive power can also be used to create a simulation for his owner to train basic combat. In Ryuga Dougai-centered continuity on the other hand, he lacks more advanced abilities the former possessed despite retaining basic abilities of Madō Jewelry (dark energy detection, Horror sensing, provides wisdom and knowledge to its wearer), but nevertheless gained new ones following his upgrade which also include the power to summon a purifying wolf statue, enabling Ryuga to cleanse his sword of built-up malevolence without needing to return to a Watchdog.

Silva.
 is the amulet-type Madōgu of Rei Suzumura, also known as Zero, the Silver Fanged Knight. Unlike most other Madōgu, she has a human like-face. She is composed in personality and behaves in a ladylike manner. Originally belonging to Douji, Sliva reveals her previous master's murderer to be another Makai Knight. Though her full abilities are unclear, she serves merely as both Rei's advisor and Horror detector as well as his sole companion. She is also shown in ', that she also acts as a communicator between Bakura's bar and Rei. During Rei's battle with Gulm, Silva took a hit meant for Rei and was damaged as a result. By the events of ', Silva is repaired and converted into a pin that is attached to Rei's left glove, though she can still be attached to a chain and given to others as a necklace. Unlike most Madōgu, who refer to their owners by name, Silva only refers to Rei as "Zero." The name "Silva" means "family" in the old Makai language.
Unlike Zaruba who is quite indifferent who he ends up with and often bickers with the one he serves, Silva is quite attached to Rei, often having friendly, teasing conversations with her partner on matters unrelated to Makai business. Until Rei begins hanging frequently at Bakura's bar, she is more often than not, the only one who keeps Rei company.

Goruba.
 is the bracelet-type Madōgu of Tsubasa Yamagatana, also known as Dan, the Midnight Sun Knight. He is an old-man in terms of personality as he is one of the oldest Madōgu in existence. Like other Madōgu, Goruba functions as a Horror detector. During the Legules tribe's attack, Goruba was briefly possessed by Legules, revealing the Horror's goals after leaving him to kidnap Rin and take the Phosphorus Spear. The name "Goruba" means "rule" in the old Makai language.

Alva.
 is the Madō Ring of Jinga Mikage, also known as Rose, the Glittering Shadow Knight. She shares a professional, casual relationship with Jinga, rarely speaking until there is Horror-related business to be addressed. She is also used to interpret the dancing ring light from a lamp at Jinga's hideout, which is used for receiving orders from their Watchdog. Unlike most other sapient Madōgu who like humanity to a certain degree, Alva is cynical and distrustful of humans in general, quipping once that she doesn't believe in friendship at all, finding eventual betrayal an inevitability. As Jinga does not remove Alva when being possessed by his dark self, Alva presumably has full knowledge of the atrocities he wrought. The reason why she keeps quiet about it is currently unknown.
Alva is voiced by , who portrayed Amily, Jinga's Makai Priestess wife in previous works.
Makai Priests.
Amon.
 is a Makai Priest who was known to be one of the greatest Makai Priest to have ever lived. He helped Taiga in creating anti-Horror weapons, spells and devices. He was the one who created Zaruba, stating that his greatest regret in Zaruba's creation is giving him a loud mouth. He's similar to Chinese Tao Priest-exorcists who learned Makai techniques along with martial arts to slay Horrors. He loves drinking red sake and playing bar chess, wagering 10 years of life to the winner of the game. Amon never completed his game with Taiga and waited 20 years for Kouga to replace his father. As Kouga nearly lost, Amon told him to return again to play another time. It wasn't long that he was murdered under mysterious circumstances and the Watchdogs pointed their fingers at his proud student, Jabi. He died holding a chess piece Koma, cluing that his killer was a Makai Knight, likely Barago. He contacted Rin to help him deliver a message to Kouga relating to Jabi.
Amon is portrayed by .
Jabi.
 is a childhood friend of Kouga who was taught in the Makai ways under Makai Priest Amon. She and Kouga trained together, but went their separate ways during their teenage years. Jabi is a sensually aggressive woman and wants to be a good woman rather than being a talented Makai Priestess. She carries two Madō Brushes to summon electrical attacks and has two red Makai flags used to ward off certain magical attacks. By the she and Kouga cross paths again, Jabi has been framed with the murder of her mentor and has stolen the purified Horror blades due to be subject to Force Repatriation. Though Kouga believes she is not responsible for the murder, Jabi is unable to trust him initially because Amon's murderer is a Makai Knight.

Rekka.
 is a Makai Priestess and one of the disciples of Akaza whose father Kengi was murdered by the Horror Karma, allying herself to Garo during the events of ". She is a tomboy in personality, resenting her nature as a female as it kept her from her childhood dream of becoming a Makai Knight and forced her to be trained as a Makai Priestess instead, briefly meeting Kouga during his training under Wataru. She wears a duster over her tunic, which is the common dressing style of Makai Knights instead of dressing like most other Makai Priests, and uses the brasher pronoun "ore" over more feminine ones like "atashi", presumably as reminders of her original wish. Rather than becoming one who support Makai Knights as usually expected of other Makai Priests, she actively goes out to hunt Horrors on her own, resulting in her above-average martial capabilities and extensive use of combat magic. Among her abilities is the summoning of the fish-like to seal Horrors.
Rekka is stoic and strong like Kouga, yet can be hot-headed and dedicated herself to hunting Horrors to the point where she would harm innocents in the process. She even resents having Kouga around at first as he might rob her of her chance of avenging her father. But during her time with Kouga, he gave Rekka the same lessons her father taught him and becomes a better person, especially when Kouga suffers serious injuries due to her over-eager approach of getting her hands on Karma. She played a key role in helping Kouga take down Karma by summoning the spirits of the fallen within the Mirror Realm, allowing Kouga to assume a more powerful form and turn the tables on Karma. Taking over the late Akaza's territory after defeating Karma, Rekka gives Kouga one of Makai Dragons if he should need to contact her and vice versa. She reappears in ' when she and Kouga cross paths hunting Sedinbale, learning more about him as a person as well as his weakening condition. After the re-sealing of Sedinbale, now understanding the Makai Knights' resolve and having new-found respect for Kaoru, Rekka returns to her territory. She confronted Shiguto, who is enthralled by Sigma's ideals and wish for Rekka to come along, reminding him of the promise they made to Kouga and asserting that no good will come to humanity, should the Knights and Priests get busy fighting each other.

Leo Fudō/Lord the Flash Knight.
 is a young Makai Priest serving the Senate whose youth belittles the extent of his genius. However, Leo is also a Makai Knight holding the title, and hides this fact from the Senate. As Lord, Leo dons a suit of light purple armor, with a horned wolf helmet. A genius inventor, Leo is the one who invented the mechanical creatures known as Gōryū that his fellow Makai Priests begin using to fight Horrors, though he does not show the same liking or passion with conventional machines. He is surprisingly humble and friendly for a young genius, without even the slightest hint of cockiness or sense of superiority, though he is shown to have a sharp tongue. Like his brother, he has no qualms about using questionable methods when it comes to banishing the Horror menace, though nowhere near as extreme as the methods of Sigma. This is evident when he persuades Mio that it is alright for Sigma to use Gyanon in his creation of Idea, and he himself later creates masterpiece Gōryū Colt by literally reprogramming a Horror to be Colt's artificial intelligence, and shows irritation when Kouga warns him about using such dangerous methods.
Both he and Sigma were trained to be Makai Knights from a very young age, and both were extremely gifted as both learned advanced magic without any formal training. Sigma was revealed to be the comparatively and significantly more gifted sibling and was the one responsible for both initiating Leo's training in magic as well as influencing him in deciding to become a Makai Priest, so as to aid Sigma when Sigma got old enough to inherit the title of Lord and the armor. Leo studied magic alongside his Makai Knight training with that intention in mind. Surprisingly, when they had both came of age, their father decided to pass the title and armor to Leo instead, enraging Sigma and prompting him to run away from home. He appealed on Sigma's behalf but his father persisted in his decision nonetheless. Sigma returned three years later when their father died. While Leo was happy to see him and wanted to pass the title and armor back to him, Sigma declared that he too shall be a Makai Priest, having found a way to permanently rid the world of Horrors, and declaring that soon, all Makai Knights shall be rendered redundant. The way to it would his ultimate Magōryū, Idea.
He was also a good friend of Mio, a mute Makai Priestess who was also Sigma's friend. She went on a trip to look for Sigma who ran away from home, and later when Sigma came home, went together with Sigma to look for ways in completing Idea, the ultimate Magōryū conceived by Sigma. She was devastated when she found out later that one of the criteria of completing Idea was providing large numbers of human sacrifices used as fuel to activate Gyanon's powers, but eventually she decided to stop Sigma herself prior to sending Leo a letter detailing what would be a suicide mission while revealing his brother's madness. Upon reading, Leo arrives at Sigma's lair too late to save Mio from his brother's wrath.
At the start of the series when Kouga is made a Makai Knight of the Senate, Leo is assigned to be his partner. During one of their earlier missions together, the aforementioned Colt goes rogue, Leo attempts to sacrifice himself to stop Colt from becoming a menace before Kouga stops him and subdues the Gōryū. He is also a caring friend to Kouga, constantly worried about the seal on Kouga's chest. While taking Kaoru with him to see the Spirit Beast in hopes that it would restore the Madō Brush that belonged to someone dear to him, revealed later to be Mio. Leo is forced to reveal his Makai Knight swordsmanship in front of Kaoru to stave off the Spirit Beast's guardian beast, and asks her later to tell no one, especially Kouga, of his ability to wield a sword along with their encounter with the sacred animal. Leo later tells Kaoru that he will be leaving for a while, with his connection to the red-masked man revealed over time as his twin brother, Sigma Fudō. Eventually, Leo is forced to become Lord in order to save a weakened Kouga from Sigma. He tries to reason with Sigma, only for his twin to denounce him as his brother.
When he and Sigma are on board the Madō Train, he attempts to reason with his brother again, as well as giving the Flash Knight armor to Sigma, claiming that it belongs to Sigma. Sigma however, is unmoved, and demonstrated his ability to summon the Jaaku armor and brands Leo with the Seal of Destruction. Seeing that now there is no hope in reasoning or saving his brother, Leo no longer refers Sigma as his brother and vows to cut him down himself. Unfortunately, Leo's martial capabilities prove to be nowhere near that of Sigma's and he is easily defeated. Leo has only manage to survive due to Kouga's nick-of-time intervention. Leo is later present during the Saezima manor's destruction, eager to join in the fight but told by Kouga to stand back, for it is his mission to put an end to his former friend. Sigma later passes his brush to Leo before passing.
In "", it is revealed that he continues to serve under the Senate, and no longer has a partner as he is both Knight and Priest. He no longer hides the fact that he is also a Makai Knight, and has come to rely on his abilities as a Knight as well as his armor more, despite still referring to himself predominantly as a Makai Priest. He sends Yuna and Kain to investigate the whereabouts of a Tekki without letting them know that he is behind the order so as to test their abilities and resolve. Despite ending up having to save Yuna personally, he commends Yuna's resolve to fight despite her lack of necessary skills, and refers to her as a Makai Knight due to her preference for the sword, despite the fact that she is a woman and will never be able to summon an armor of her own. While she initially doubts her status, she tells her that what matters as a Knight is her pride as a Knight, not the armor--a quote from Kouga that he has taken to heart.
As Lord, Leo dons ornate periwinkle and gold armor and wields a massive scimitar-like blade.

Ratess.
 is a Makai Priest serving the Senate who is extremely prideful due to his lack of inner darkness and strict adherence to the rules, also harboring a hatred for Makai Knights, perceiving them to be conceited just because they are the ones to hunt Horrors. Meeting Kouga while given the task to deliver a Spirit Beast pelt to other Makai Priests, Ratess voices his apparent dislike for Kouga while stating his ideals that in the business of eliminating Horrors, individual strength matters little. However, Ratess is later revealed to be in league with Sigma, identifying with his ideal of removing the Makai Knights and dream of the day where Makai Priests will rule everything again. He kept the Spirit Beast pelt and personally delivered it to Sigma along with the Madō Brushes of other Makai Priests dedicated to their cause. However, refusing to hand over the Madō Train's key when asked, Ratess is murdered by Sigma, stating that he has no intention of becoming king and that Ratess is just as arrogant as the Knights they both resent, and thus has no right to live.

 is a mute Makai Priestess who was a good friend of Sigma and Leo, seen only in flashbacks. After Sigma left when denied the title of Lord, Mio chose to look for him and became his assistant in the construction of Idea. During her research, she came across records of the Horror Gyanon and expressed her fearful dismay of Sigma intending to use its corpse as Idea's core. Though she visited Leo to state her fears of this venture, Mio is devastated later upon learning that a large amount of human souls are needed to power Idea. Sending Leo a message about his brother's intentions, Mio attempted to destroy Gyannon. However, though it pained him, Sigma murdered her with Leo arriving too late. Since then, Leo kept Mio's Madō Brush on his person.

Burai.
 is a Makai Priest in Vol City who trained Ryuga on an isolated island with his Makai Beast Ragō as Ryuga's training partner, being the childhood friend of the youth's mother Hakana. He does not talk much and rarely shows emotions, usually opening his mouth when he issues orders or when the matters at hand need to be addressed. He nevertheless exudes an air suggesting that he knows far more than he lets on. Originally, as a child, Burai came to the Tower of Heroic Spirits alongside Hakana mocked the blackened Garo armor alongside his childhood friend Ouma before told how the armor lost its radiance and decided to help Hakana in its restoration. As a result, Burai learned of Zedom and the Madō Horrors. Later believing Hakana died alongside their friends in Hill of Zedom's Arm, Burai was wracked with guilt to the point of attempting suicide. He was stopped by Ouma, and seeing Ryuga and Rian continuing despite losing their families, Burai adopts the latter and trains her before seeing her to Kantai to complete her training. It was only once she graduated that Burai stationed himself at Vol City, which lacked a protector at the time. As the unofficial leader of the Makai Knights stationed at Vol City, Bura normally works behind his desk and issues out. When needed to, Burai can personally oversee matters with by summoning Ragō that can devour Horrors. Though he kept his side of the story behind the Madō Horrors as well as their origins initially from the group, he aids them by developing the Madō Horror Detector to make their hunt for them more easy.
During Tousei's massacre of the Kaneshiro family, Burai is knocked out by Sonshi and remains unconscious for most of the time the rest of the group going to confront Tousei, waking up only to find that they are making a dire mistake and that he is too late to stop them. Nevertheless, Burai manages to catch up with the group and creates a distraction enough to have Aguri and Takeru flee the scene while spiriting away a young Makai Priestess he recognized as Hakana while leaving Zaruba with Ryuga. As the resurrected Zedom begins to break free from his prison, Burai resolves to stop the Horror in what he expected would be an act of sacrificing himself by becoming a sealing vessel to ease Zedom's wrath. Being confronted by Ryuga who knows his plan right from the start, he reveals that that had always been his plan since the day he failed to protect Hakana, telling Ryuga that he loved both Rian and Ryuga as if they were his own and they were the ones who kept him going. Though he failed in his intended sacrifice, with his Madō Brush remaining after the Horror obliterated him, Burai succeeded in creating a weak spot within Zedom that the Makai Knights capitalize on.
Burai is portrayed by .
Rian.
 is a flashy Makai Priestess who has trust issues due to her upbringing. She is Burai's only disciple, entrusted to Burai's care before her father died. Initially planned to be sent to Kantai soon after adoption, her actions and singing unwittingly inspired Burai, who attempted suicide, to live and honor his words to the friends he lost. She was trained personally by Burai for several years before being sent to Kantai for further training, graduating as one of the top students and attributing her success to Burai's early teachings. She left for Vol City with Burai as soon as she went home after graduation. Unlike other Makai Priests, Rian used a more so than the traditional Madō Brush. She is also skilled in changing her appearance, often going around places looking like an ordinary girl of her age and doing undercover work to dig out Horrors, sporting her Makai Priestess look only when she needs to fight.
At first, dating only the rich and those whom she perceives to be strong so not to suffer the same pain of losing a loved one like as a child, Rian took an interest in Ryuga despite not thinking much of him initially. But over time, getting to know Ryuga better over time with a better idea of how strong he actually is, Rian eventually developed feelings for the Makai Knight, going so far as to even suggesting that they "make a baby" together. Her initial interest and later infatuation with Ryuga develops into a lasting friendship.
Rian also becomes fast friends with Enhou due to their ideas of self-empowerment. She is devastated when she confirms that Enhou is no longer human, and despite Ryuga having an upper hand in the fight against Enhou, she begs Ryuga not to cut Enhou down, which coincidentally is something Ryuga is reluctant to do himself. She later ends up as Tousei's captive to serve in the germination of a new supply of Madō Horror Plants, attempting to rekindle Enhou's humanity while taken to Hill of Zedom's Head. Luckily, Ryuga saves Rian as she helps him slay Enhou when Tousei sends her after them. Not wanting Enhou to be remembered as a monster, Rian assumes her identity to expose the conspiracy set against her and her friends while having the SG1 members believe that Enhou died a human. Keeping her friend's necklace as a keepsake, Rian vowed to carry out what she believed to be Enhou's dream of a Vol City without Horrors. Once Vol City is saved, Rian erases all memories regarding the Makai from the residents, intending to remain in the city to protect the Makai Priest ruins. But Aguri taking over her duty allows Rian to travel with Ryuga to support him as Burai and Hakana have. 
She continues to travel with Ryuga before the events of "Goldstorm Sho", now sporting a new appearance and considerably less reliant on disguises. She also sports a new Makai Gun, which ironically, is only used sparingly. While on the quest of sealing Radan, Rian befriended a young teacher named Mina whose upcoming marriage makes her consider her relationship to Ryuga. Though Rian created a barrier to keep her safe, the actions of Amily resulted in Mina's death, which Rian continues to blame herself for.

Hakana.
 is Ryuga's mother and a childhood friend of Burai and Ouma. She possess the uncanny trait of hearing thoughts embedded within objects, which is later inherited by her son, Ryuga. She is the Makai Priestess who took it upon herself to restore Garo's radiance since she first heard of the armor's plea to restore its radiance, during a trip to the Tower of Heroic Spirits as a child. Ten years ago, in a risky chance to restore the Garo armor's radiance, Hakana became one of the priestesses to sing Zedom's Requiem to germinate a Madō Horror Plant at the Hill of Zedom's Arm. However, the unexpected interference of Tousei Kaneshiro resulted in Hakana being knocked out by Zedom's freed arm and seeded with far more Madō Horror Seeds than initially intended, before being carried to the Hill of Zedom's Head. Hakana is then forced to germinate Madō Horror Plants with the seeds in her, losing her memories bit by bit with each germination and regressing in age. By the time the final Madō Horror Plant was removed from her body, while still singing to keep Zedom from awakening, Hakana has regressed to a childlike form. Despite this, Hakana indirectly aided Ryuga with her singing and played a role in his armor's restoration. Whenever Ryuga defeats a Madō Horror, he is shown some of Hakana's memories. Eventually, with Rian ending up her replacement, Hakana is taken to safety by Burai and is restored to her proper age. Though she reunites with her son, sacrificing her eyesight to restore Ryuga's, Hakana reveals that being made to germinate multiple Madō Horror Plants has caused her to slowly transform into a Horror with Zedom's resurrection speeding up the process. She eventually has Ryuga cut her down after witnessing the Garo armor regaining its golden radiance.

Yuna.
 is a Makai Priestess whose father Kuroudo was murdered by the Horror Ring. It was not known how she was like before Kuroudo was killed, but currently she sports brooding and impulsive personality, a result of being consumed by thoughts of vengeance towards Ring yet painfully aware that she does not have what it takes to cut down her father's murderer. Like many priests and priestesses, she was not trained in the use of Soul Metal weapons. In desperation of wanting revenge against her father's murderer with her own hands, she had Kain magically implanted a segment of a bone from his father's severed arm into her arm, which allows her to use her father's Makai Sword but puts a tremendous strain on her body, causing her intense pain whenever she overexerts herself. In ", she seeks Rei's help together with Kain, after coming to conclusion that both of them alone are inadequate to defeat the powerful Horror.
Despite being moderately skilled in battle, her impulsiveness and thirst for revenge always gets the better of her. That, coupled with her inexperience in wielding a Soul Metal weapon, results in brash and clumsy attacks that are easily predictable. In order to keep her from hurting herself further, Rei challenges her to a fight and easily beats her senseless, driving home the message that her current mindset and skills do her no good in their quest of hunting down Ring. While she is known to be a Makai Priestess, she has yet to display any skills with magic, with the only priestess-like ability being the song she inherited from her mother, Iyu.
In ", it is revealed that she is active as a , and continues to be Kain's partner. Though improved noticeably since she first took up her father's sword, she still lacked the necessary finesse and constitution required to properly wield a Soul Metal weapon. She has also taken up a brush and started training as a Makai Priestess. However, due to serious lack of formal training in her formative years, she is currently only capable of simple, crude spells which she uses in conjunction with her sword. Her status as neither a full-fledged Knight or Priestess, but some weird and incomplete hybrid of both, causes her tremendous anxiety and sense of inferiority, which she usually hides under a cheerful facade. She is driven into further desperation due to being a woman, and as such is unable to inherit his father's will and become a Makai Knight.
After a mission to slay a Tekki, secretly assigned by Leo Fudō, also known as Lord the Flash Knight, Leo invites her to join him at the Senate. Yuna refuses out of a desire to carve out her own path as a unique warrior within the Makai Order, vowing to train her abilities to their fullest despite her inexperience at her age and inability to ever summon her father's armor.

Kain.
 is a Makai Priest and Yuna's partner who was formerly Kuroudo's partner. Despite appearing goofy and laid-back, it is actually a front with which he hides his pain and sorrow. He was with Kuroudo when they had Ring cornered, but he was unable to prevent his partner from being killed by the powerful Horror. Distraught and wracked with guilt, he conceded to Yuna's wish of having a bone from Kuroudo's severed hand implanted in her hand despite knowing the act to be a bad idea, as while it allows her to use Kuroudo's Makai Sword, it also puts a tremendous strain on her body.
He is somewhat of an alcoholic and can often be seen drinking beer when not fighting. Unlike most priests of his time, he seldom uses his brush and wields a all the time in battle. The umbrella can be used as both a shield and a shotgun.
After slaying Ring, he continues to hang around with Yuna as her partner, and it is suggested that he has developed feelings for her. He continues to train her to be a Makai Priestess, but finds it very difficult due to both Yuna's insistence to prioritize her sword over her brush, as well as having a totally different style of combat from her. He is stronger than he looks and is noted by Leo to be a capable Priest. Despite being concerned with Yuna's mental state, he chooses to play along with her cheerful facade most of the time, opting to remind her that she does not have to rush and that he is around for her at times.

Though the ritual failed, Busujima mistook a half-awake Mayuri's attempt to ease him as a response from his lover before learning in the present that her soul long departed.

Bikuu.
 is a Makai Priestess who is a Darkness Slasher. When her brother Izumo falls into darkness prior to becoming the host of the Horror Latel, Bikuu remains intent to slay him on her own, but is forced to team up with Raiga and Crow as she alone prove to be inadequate in completing this particular mission. Once Izumo is slain, Bikuu begins her search for the person responsible for breaking the seal on the Ady Slate. Once she found Eiji Busujima however, despite noting that he still committed a heinous crime against their order, Bikuu deems him no longer a threat against their order or humanity and helps to treat his wound. She later goes hunting for Zesshin, getting acquainted with Daichi, who later becomes her apprentice, in the process. She learns during this mission that there is more to the human heart and mind than the color of their orbs within, from how Mutsuki's orb turns black while killing her peers trying to steal a spell allegedly to save her son, Daichi, and how the orb of her former master, Byakkai, stays white despite him being the one orchestrating the entire Zesshin incident. She goes against her code of breaking blackened orbs, and executes her former master by breaking his still-white orb, using the Soul Insertion spell.
As noted by Crow, she is one of the Shadowfolk and that her profession of hunting humans instead of Horrors makes her appear untrustworthy, as well as resulting in her emotionless outlook and inability to trust others. However, she is far from being unreasonably cold and paranoid as expected by most of her peers, and is quite a reasonable and gentle person, seen due to despite her job of hunting fallen Makai practitioners, she is willing to give any redeemed ones chances to make amends.
Due to her work as a hunter of potent Makai practitioners, Bikuu is a capable fighter, whose martial prowess is considered one of the best among Makai Priests and even rival those of Makai Knights'. Her magic, as a result, also leans heavily towards tracking and combat. She wields a somewhat thicker and longer brush, which serves as an effective short striking weapon other than a focus to channel magical energies. One notable technique is that she can conjure a bow using her brush as a focus and use it to shoot powerful spiritual arrows. Although it is a powerful move, it is impractical in most cases due to time required for the conjuring, and also because the move is very taxing. Unlike most Makai practitioners, her garb has little leather to maximize ease of movement, and she wears a reinforced conical which also serves as a throwing weapon. When she battles in a person's mind, she becomes wearing white clothing. While fighting Zesshin in Daichi's mind, she becomes through Daichi's spell.

She is severely injured and weakened in the battle with Agō, forcing her to remain on her throne to heal for quite some time afterward. During her recuperation, she effectively acts as Ryuga and Rian's Watchdog, giving the duo assignments and informing them of major Horror activity. Once she is fully healed, however, she joins the group in battling Jinga and Amily. Despite her small stature, Ryume is more than capable as a combatant, using her two scroll hair accessories as catalysts for her spells, as well as implements to bind her opponents.
Despite being wise, seasoned and hardened due to having centuries of experience dealing with Makai practitioners and threats, she smiles a lot and behaves kindly and playfully until situations force her to be serious. Due to her age, experience and powers, she is usually revered by those around her and addressed to with proper honorifics, although Ryume herself does not care much for status and prefer to treat her juniors as equals.

While a laid-back, observant, and in general a competent Makai Priest despite his young age, Gald has a holier-than-thou attitude with a tendency of treating others as tools. In Rian's words, Gald is little more than a brat who is overconfident with his abilities. He is very proud of his heritage and has little tolerance for anyone whom he sees to be insulting him or his now near-extinct people. His heritage is where his sense of duty on sealing Radan stems from, and he is serious about it to the point of refusing aid from others on completing the task.
At first, Gald stays out of the way, keeping an eye on Ryuga after learning that the seal containing Radan has been broken. But once Ryuga leads him to Jinga, Gald makes his presence known as he interrupts their fight, reforms the Hōken and spirits the sword away. While Gald's refusal to have their help caused Rian to mistrust him to the point of fighting over the Hōken, she and Ryuga decide to let Gald be after seeing the protective talisman Haruna made for her brother. While Gald grudgingly acknowledges Rian and Ryuga afterwards when they saved his sister before rescuing him, he still insists on acting on his own while warns the duo not to interfere. It isn't until that he himself got captured and nearly having to kill himself in a bid to take down Jinga, subsequently being saved by Rian and Ryuga who goes to his rescue, that he finally acknowledges his own limits, decides to put his trust on the two of them, and enlists their help in completing his mission. While he still holds enmity against all Makai Knights in general, he decides to deem Ryuga and Daigo to be trustworthy ones. 
Gald is dressed predominantly in black like all Makai practitioners. His garb consists of an elaborated black robe, adorned with navy blue belts over his left shoulder and a short sleeve on his right which is mostly red. The puppet through which Haruna communicates with him is pinned to the right breast of his robe, which is thought initially to be a Madōgu. Gald is a formidable Makai Priest, well-versed in martial arts and adept in combat magic, with his signature move being very short-range teleportation, which he can also bestow temporarily on others through use of tags. As a descendant of the Homura Village, where two of his ancestors were responsible for sealing Radan, he is knowledgeable on the use of the Hōken, as well as sealing techniques and rituals required to seal Radan.

Haruna.
 is a Makai Priestess and Gald's physically frail younger sister, the two having fled to Homura village when Moyuru sacrificed himself to hold off the rogue Makai Knight, Jinga, and rogue Makai Priestess, Amily, slaughtering everyone in their day. She is forgiving, observant, and in general more serious in personality than Gald, often seen urging him to get on with his work and giving advice in Makai-related matters. Despite having her home village slaughtered by a rogue Makai Knight, she does not share Gald's encompassing hatred for all Makai Knights. Because of her frailty, which at times makes even standing up on her own incredibly difficult, Haruna is confined to a house hidden deep in Yousei forest while using a Madōgu-like puppet made from scrap materials to stay in contact with her brother while he is away.
She was entrusted with the Hōken as, through Gald's unpleasant encounters with Ryuga and Rian, he deems it too dangerous to keep with him. After seeing how Ryuga and Rian put Gald's well-being before their mission, vowing to help rescue him despite having no need to do so, she decides to entrust the Hōken to the duo while taken under Ryume's care. She later resides in Tienda de Bolts and acts as support for Ryuga and company using a mystical book, which is able to project maps and floorplans, and special charms that serve the same function as Gald's puppet. Later, and at Gald's insistence, Haruna temporarily gives up being a Makai Priestess and enters normal civilian life, enrolling in a high school under the name . While at the school, she befriends the astronomy club and the delinquent student Meguru. A shape-shifting Horror infiltrates the school one day and Daigo Akizuki, having disguised himself as a gym teacher to hunt the Horror, slays it as it attacks Haruna and Meguru during an astronomy club event. The next day, Haruna leaves the school after saying her goodbyes to Meguru and returns to being a Makai Priestess, resolving that her dream is to protect the hopes and dreams of others.

Okina.
 is a Makai Priest and Kagome's older brother. Both siblings were raised in an impoverished household of low status within the Makai community. Lacking both talent and training, Okina and Kagome were weak, mostly self-taught priests who only became capable of taking down Horrors when they became young adults. Despite the harsh circumstances since childhood, Okina nonetheless trained diligently and became his sister's mentor. Seeing potential in Kagome, he seek ways to enhance her sister's power and stumbled upon records of the Dragon Knight.

Both siblings were raised in an impoverished household of low status within the Makai community. Lacking both talent and training, Okina and Kagome were weak, mostly self-taught priests who only became capable of taking down Horrors when they became young adults. Nevertheless, she looked up to her brother and trained as hard as she was able to, eventually developing a specialty in erecting personal barriers. She is capable of erecting barriers both on herself and on others, and are strong enough to repel repeated strong attacks.

Fusa.
 is a Makai Priestess and Jinga's partner. Her origins and how she ends up with Jinga is yet-to-revealed at this point. While looking meek and having nothing to suggest her being a capable combatant, she is indeed a professional, capable support to Jinga. Her spells tend towards restraining Horrors instead of attacking them head on, creating openings for Jinga to land the killing blows. Her position otherwise is more like that of a clean-up crew in the field rather than a sidekick, usually tasked with evacuating civilians caught in the fray, wiping their memories of the ordeal, casting spells to make sure civilians around do not find them out of place, and so on, while Jinga often goes on to fight the Horror alone. Fusa is often seen concerned of Jinga's mental wellbeing, but never intervenes so much that it would annoy his partner. It is later revealed in the ordeal with the Horror Fons that her concern for Jinga runs deeper than initially speculated, as she is seen doubting whether she had made the wrong choice becoming a partner of Jinga, who is now psychologically damaged and deemed incapable to operate at his full capacity, as well as her own abilities as a Makai Priestess. She nevertheless chooses to stand by her Knight and her choice, dispelling the hold Fons' intention of amplifying her inner darkness and have her possessed.
Fusa begins to take notice of Shijo's absence and Jinga's occasional mood swing after that unusual night, suspecting that Jinga might be suffering from dissociative identity disorder and confiding this to Yoyu. Regardless, unaware of the evils committed by Jinga's past life, Fusa remained by Jinga's side as he ends up on the run from Kerus over his refusal to turn himself in for an inquiry of his power. Fusa attempts to reason with him for Toma's sake, only to be killed by Jinga as he accused her of betraying him.

He develops the hypothesis that Mizuto was stabbed with a dagger tainted with dark qi and forcefully turned into a Horror, and voices this out to Jinga when they meet again.

Other protagonists.
Kaoru Mitsuki.
 is the narrator and the female protagonist of the first two series, an aspiring 22-year-old artist who always having trouble making money. She is the daughter of a painter and his wife , the former having written a children's picture book based on his encounter with Taiga. Though she had no memory of the event, Kaoru was chosen by Barago as the medium to summon Messiah and serve as her host in the human world.
Meeting Kouga at the start of the first series, Kaoru ends up being infected by Horror blood with Kouga sparing her life instead of killing her. Unaware of her condition, or Kouga's reasons, Kaoru ends up unknowingly helping the Makai Knight at times as Horror bait. To keep taps on her, due to her bad luck in attracting Horrors, Kouga has Kaoru wear a ring created from Zaruba's being. After being evicted from her house and accidentally making her friend Asuna sick while temporarily freeloading, Kaoru moves into the Saezima estate while intending to earn her keep. Having developed feelings for Kouga, Kaoru is devastated when she found out Kouga used her as Horror bait before eventually forgiving him prior to the Makai Knight saving her life with the Barankas fruit. However, while trying to complete the last page of her father's book, Barago abducts Kaoru to enact the ritual to summon Messiah before Kouga save her and thwarts the scheme. Soon after, Kaoru leaves for Italy to further her art studies, finishing the last page of one of his father's Golden Knight picture book and giving it to Kouga. Though it was never revealed to the audience what the last page looks like, it nonetheless brought Kouga to tears.
She was seen painting a picture near the end of ' in the Saezima estate, welcoming Kouga home and seen holding hands with him. By the time of ', she becomes a regular visitor to the Saezima estate and works on publishing her own picture book based on the inspiration of her experiences throughout the second series, "The White Spirit Beast and the Mysterious Forest". Having gone through many hardships with Kouga, she has come to understand him enough to be able see through his stoicism much like Gonza, and now far more willing to put up with his antics. Forced to part ways with Kouga again when he leaves to uphold his end of the bargain with Gajari, Kaoru eventually sees Kouga after his return two months later.
In ", it is revealed that Kaoru and Kouga married and had a son, Raiga. But while Raiga was still a child, Kaoru was suddenly abducted into an unknown realm, with Kouga going out soon after to rescue her. Though believing his parents died, Raiga learns that his father is still alive when he inherited both the Garo armor and title, with hope that he may eventually reunite with his mother as well.
By the time of " and its mini-series prequel, Kaoru and Kouga finally reunite somewhere at Promised Land, but the-then animated Kiba Armor unexpectedly appears, possessed by Barago's surviving evil qi. It was after seemingly defeated Kiba she and her husband discovered that not only Eyrith being the one who separated her from her family, but also their son fight a losing battle against the legendary Horror, thus necessitating Kouga to send Zaruba to his son to aide him to become the next Garo. As soon as the recovered Kiba set his sight on Raiga, she assists Mayuri in sending Garo Armor purified by their combined feelings to Raiga while Kouga, Raiga, and the revived Taiga deal the Dark Knight.

Gonza Kurahashi.
 the butler of the Saezima household who has served the family for three generations and the only family Kouga had after his parents died. Gonza attends to all butler related duties like cleaning the house and cooking, while also advises his masters on certain matters. He helped raise and assist Kouga with his training since childhood. Though having been exposed to the Makai world for over fifty years (between Taiga, Kouga and Raiga), Gonza is a regular person without any form of Makai training other than the ability to read the old Makai script, thus is not considered a member of the Makai community proper.
Gonza is also on good terms with Kaoru and is usually seen encouraging Kouga's relationship with her. He was featured in "Garo Side Story" as "God of Pictures", but the sequence was part of Kaoru's dream. Gonza was featured in ' as his usual self looking after the household. In ', it is revealed that an aged Gonza still works for the Saezima household, now under Kouga and Kaoru's son Raiga. Just like he did with Kouga, Gonza raised Raiga by himself and helped in the boy's training after his parents disappeared. He is also very friendly with Mayuri, and like Raiga, opts to see her as a person rather than just a Madōgu.
Despite being a servant of the Saezima household, Gonza often does far more than is required of him and would happily go to lengths to assist his masters as well as the stay-in guests, and sees everyone in the household as family. In return, the masters of the Saezima household all treat him as their own family rather than only as a servant. 
Despite hardly seen anywhere outside the Saezima estate, Gonza does have friends and acquaintances, at least within the Makai community, as he is known to be an old friend to Anna, a retired Makai Priestess who is currently an owner of a restaurant and a chef, whom he had known since his time working for Taiga.

When Kaoru lost her apartment Asami reluctantly allowed Kaoru to move in for a few days. Kaoru made a dish for Asami as a way to appease her, but made her sick instead. Asami was sent to the hospital, which at the time was filled with Horrors, but she was not devoured. Asami eventually was phased out of the story line and only appeared once in a while to show she's still in contact with Kaoru. She returned as the "God of Painting" in "Garo Side Story".

Rui Suzaki.
 is a young girl who moved to Vol City with her mother , her grandmother , and her little brother , interested in a program that offers free housing to newcomers, unaware that it is actually a trap to lure outsiders to be preyed upon by the Horrors. Despite Takeru's warnings, Rui and her family insists to take part in the program and after learning the truth, they are rescued by Ryuga and his companions. Rian has Rui and her family's memories altered so that they forget what happened and believe that they were rejected by the program, but Sonshi appears to them as they leave the city and instructs them to return. However, Rui remembers about Takeru and manages to survive by jumping from the car while the rest of his family is taken away to Kaneshiro Foods where their souls were sealed away in capsules with their bodies incinerated. Found by Burai and the others, Rui's memories are then completely altered to have no memory of her family as she starts working at a flower shop. Despite being ordered to not interact with her anymore for fear of triggering the emergence of her original memories, Takeru approaches Rui, becomes her friend and looks out for her while later enabling her family to rest in peace after learning of their fate. Despite having her memories completely altered, bits and pieces of her behavior and habits during the time spent with her family still lingers, proven for her habit of gazing at the moon. While she herself currently unsure why she likes looking up at the moon so much, Takeru quotes that it is due to the habit bringing up a sense of nostalgia, as that is what she used to do with her family often.
Soon after Zedom is finished off, she is seen with a florist stall of her own, where Takeru goes to check on her. Now with her memories relating to the Makai erased again like everyone else in Vol City, she could no longer recognize Takeru, but in order to preserve his time with her, he vows to live properly from here on out nonetheless.

Bakura.
 is the one-armed owner of the bar , which Rei frequents. He is aware of the Makai Knight's duties and acts as his support in a relationship similar to that of Gonza and the Saezima clan. Bakura allegedly lost his arm during a run-in with a Horror. From " onward, he wears an artificial arm containing a Madō Brush.
Bakura is portrayed by .
Mayuri.
Though referred to as a Madōgu , is actually a human who was born while her Makai Priestess mother was possessed by a Horror. Her mother's lingering thoughts for her prevented the possession to spill over to her while she was still in the womb. The ordeal gave Mayuri the power to detect Horrors and seal them in her body - a never-before-seen ability in any human. Entrusted to Shidou, Mayuri is raised until she reached adulthood, then placed within suspended animation in a casket until her talents are needed. She is raised with her human emotions suppressed, as having emotions is widely seen by her caretakers as a liability due to the nature of her powers.
Mayuri is eventually assigned to assist Raiga in tracking down Eyrith, using her power to absorb the petrified remains of the nine Horrors that formed Eyrith's prison. Despite appearing to lack emotional expression and find it hard to comprehend emotions, due to never being treated as a person before meeting Raiga, Mayuri sports a dry wit and appears to be able to dream and have preferences. Due to her emotionless upbringing, she does not care much about how she is being treated, be it as a mere object or otherwise, but both Raiga and Gonza both insist on treating her like a person nonetheless. This results in her being more expressive during her later days with the Saezima household, despite still sporting a deadpan face most of the time. Due to having never drank liquor before, Mayuri is easily inebriated (to the point of blacking out after a single sip of whiskey). She also lacks an appreciation for taste as a result of her upbringing.
By the end of the series, the ordeal of sealing Eyrith left her severely weakened and powers extremely unstable, requiring a 'resetting' ritual which would, as a side effect, wipe her memories, else she would soon die. However, now acknowledging herself to be a human and wants to live as a human, Mayuri begs in tears to be allowed to die as a human instead of carrying on as a Madōgu. She is then persuaded by Raiga, Crow, Gonza, Shidou and Bikuu to go with the ritual, assuring her that they will be by her side and do their best to bring her back as a human again. She is left comatose and in the care of the Saezima household for an unspecified amount of time after the ritual. When she comes to, she greets Raiga with a smile for the first time, suggesting that she retained most, if not all, of her memories, as well as have her emotions 'unlocked'.
She seals Horrors by means of a cage within her. She is warned to never open the cage on her own, as it would severely weaken and even kill her. However, she crossed the line due to her sympathy for Barg as a fellow Madōgu, wanting to seal the creature to give it peace, causing her to weaken over time. Her weakened state finally causes the cage to reach critical point when she seals Idora, causing the newly sealed Horror's essence to spill. This causes Mayuri to start to hallucinate and develop a lust for blood. Fortunately, Raiga manages to dive into her consciousness in time and slay Idora once again, preventing the Horror from possessing Mayuri and allowing the cage to be re-stabilized.
In ", Mayuri is shown to be somewhat more expressive and open than before, though she still retains a generally stoic, analytical demeanor. She finds a friend and confidant in the retired Makai Priestess Anna, who encourages Mayuri to visit as often as possible.

 is a retired Makai Priestess who is a longtime friend of Gonza's, referring to him affectionately as Gon-chan. She is the owner of the western-style restaurant Kitchen Anna. Gonza seeks her help in order to learn how to enable Mayuri enjoy meals like normal people do and see her smile. While she is helpful and lends her kitchen to Gonza to make an ideal dish--one that she finds to be superb indeed, Gonza laments still that it would not be enough to make Mayuri happy and realizes that there is more to it than just cooking. She breaks out her old Madō Brush and equipment at Gonza's request to infuse a soup bowl with a swimming Makai Dragon illustration, a trick that works successfully to make Mayuri smile while enjoying a meal, while also showing that despite having retired for some time, she has not lost her touch as a Makai Priestess.
In "", it is revealed that she runs not only the restaurant but also the tea shop Cafe Anna.

Once such event had him cross paths with Ryume when he and Ginji nearly caused a mass Horror infestation of the surrounding area. Originally running a mobile kebab shop in Line City, D Ringo later opens a miscellaneous goods shop called Tienda de Bolsa that ends up becoming a meeting place and base of operations for Ryuga and company during the events of '. He tends to dislike getting involved in Horror-related matters despite having extensive knowledge of the Makai arts and is known to be something of a cheapskate.

Despite apparently being an ordinary human, she possesses a moderate awareness of the Makai world and Horrors and is drawn to Rei for being a Makai Knight despite his attempts to push her away. Because she is the one who sealed the cage around the Dragon Egg, her handprint is the only one that can unlock the cage again, making her a target for Edel. Edel later kidnaps her and forces her to release the egg, but she escapes with it and delivers it to Rei and Rekka. When she is told that someone from the Senate will arrive to dispose of the egg, she takes it and runs away. When the Dragon Egg finally hatches, she takes it upon herself care for the newborn dragon, which she names after Bakura's bar, Lupo. Lupu, having imprinted on Alice immediately after birth, instinctively follows and protects her, possessing magical abilities on par with a moderately powerful Makai Priest, able to spit flame and teleport itself and others at will despite being barely a day old.

Toma Mikage.
 is Mikage's younger brother, having been trained from childhood to become Makai Knight himself. While he is physically capable, he has yet to be able to wield Soul Metal blades. Toma was present when his father Mizuto slayed his mother, accusing Jinga to be a Horror before being pushed aside by Mikage to deal the killing blow. The event traumatized Toma so much that Yoyu, a friend of the family, seals the memories regarding the event. He was under the care of Yoyu for half a year and is currently living with Mikage and Fusa. Concerned over Toma's overconfidence and inexperience with Horrors, Mikage and Fusa bring him to an abandoned building to help them in exterminating the Horrors living that. While Toma quickly steadies himself with encouragement from Mikage and Fusa, he ends up charging into the lair of the Horror Fons who restores Toma's suppressed memories. 
This resulted in Toma becoming a Horror's host and acting on intent to kill Mikage to avenge their parents. But while Mikage appeared to kill him, he actually suppressed the possessing Horror with himself and everyone else believing him to have purged it from Toma's body. Mikage chooses not to wipe his brother's memories of the ordeal and he deems it important for Toma's growth, with Toma reasserting his vow to become a Makai Knight and never again to fall victim to such a situation. Nevertheless, he becomes proud of his brother's unique and never-before-seen abilities, and his status as the first exorcised human in the Makai community. But Toma eventually surrenders himself to Kerus to be properly inspected, later attacking Mikage upon learning he murdered Fusa with his Horror form awakening as a result and ends up being devoured by the fully resurrected Jinga.

Antagonists.
Barago the Black Fang/Kiba the Dark Knight.
 is the main antagonist of the first series. Barago is the only Makai Knight who transforms without a Soul Metal weapon, but instead a Madō necklace, blowing on it to activate it, then swinging it to become the Dark Knight. Unlike other Makai Knights, Barago's Death Metal armor is organic-looking due to the Horrors he has absorbed.
Barago was the son of a Makai Knight and a Makai Priestess and had a happy childhood. When his mother fell ill, Barago intended to protect his mother and thus decided to become a Makai Knight himself through harsh training. However, forced to watch his mother turn into a Horror before his father kills her, Barago left home to find a himself another teacher, as he was unsure if his training with his father was of any use. News of his father's death came to him soon after he left home, but he felt no sadness as he thinks that his father died because he was weak. To that end, he became a talented Makai disciple of Taiga Saezima, hoping to become the next Garo. But refused the right, Barago's desperation for power grew and Messiah heard his need, appearing before him when he enter a forgotten lair filled with forbidden techniques. Messiah proceeded to offer Barago her power in return of enacting the legend of , giving him both the name and armor of Kiba.
After enduring the Soul armor's time limit, managing to will himself out of his form by absorbing a Horror, Barago proceeds to assimilate the attributes of Horrors he defeats through absorption; however, this came at the cost of his own humanity. Subsequent usage of the forbidden magics tainted the Soul Armor and reconfigured its form with more Horror-like features and twisted Barago's soul. It was then that Taiga was forced to take action against Barago, pursuing his corrupt disciple and engaged him in combat. Though he fatally wounded his former mentor, Barago was scarred with the "Mark of Death" as Taiga's final move in hope that the scar's effect would kill him in a few days. But the Horrors dwelling inside Barago's body enabled him to elude death, though his face became horribly deformed. It was by that time that Barago came to the realization that he despised Makai Knights more than Horrors as he devoured them as well.
Barago soon began to devise a plan to speed up his Horror consumption by creating his own Horror gates by infusing bits of his darkness into objects. Because of his amplified strength over years of reaching his quota of a thousand absorbed Horrors, he became stronger than any Makai Knight and eventually defeated his nemesis Bado. With his ultimate goal nearly achieved, Barago proceeds to find an ideal girl to serve as a living gateway for Messiah to possess: a girl of age six born on the sixth day of the sixth month. He found Kaoru soon after and marks her to become his gateway. Soon after, Barago used a potion he stole from Rei's foster father to change his face and oversee Kaoru's progress as her personal psychiatrist and counselor . It was by this time that Barago learned that Bado left a means of redemption in his being and was ordered by Messiah to remove all traces of it from his body.

In the process Amon was murdered and Jabi disposed of, using Rei's need to avenge his step family to kill Kouga off as well before Kiba reveals himself.
Later Barago brought a recently dead female human body to serve as a host for the Watchdog Priestesses' spirits, assuming their true forms as three old women while melding into the host body.

Only able to escape death by the Yin-Self Gate's barrier, the event aroused Tousei and he desired to make use of the Horrors' power. This led to Tousei obtaining the Madō Horror Plants when he interfered in a ritual held by Hakana and her group, siring her protector Sonshi as his first Madō Horror.

Once his cover is unexpectedly blown by Kensui, Tousei decides to take full control of the Kaneshiro Group by having Enhou and Rivera kill off his siblings and their families, with Ryuga's group serving as scapegoats in the 15 murders, so he would be the sole remaining heir before having Sonshi kill his father. When confronted by Ryuga's group, Tousei reveals his humanity and gloats that they are bound by their laws to not harm him as he guides them to the resting place of Zedom's head where he attempts to convert Ryuga due to the circumstances no longer being in his favor.

He is able to assume an armored form called by removing an evil qi-tainted dragon fang from his necklace and stabbing it into his arm. His armored form, despite appearing to be more powerful than a Makai Knight's armor, has the side effect of incapacitating him for a certain period of time afterwards, and requiring him to force said fang out from his body in a rather painful manner. He possesses the ability to command dragons regardless of their prior allegiance, able to turn back Rekka's summoned young Makai Dragons with a word, and create dragon familiars out of various kinds of scraps called to serve him. He can also set his blade aflame by scraping it across his forearm. In his unarmored state, he is able to use a stinger-like tail that can extend from his upper back.
Edel hailed from a time long before the emergence of Makai Priests, where humanity had yet to discover ways to fight Horrors effectively. He was made a sacrifice as an infant by the humans of his village to appease the Horrors, but was rescued by a dragon before he was devoured by said Horrors. The dragon raised him as her own, naming him "Edel", which meant "the land" in dragon language, and taught him everything he knew, including ways of slaying Horrors. Eventually, the dragon passed on during his teenage years, her remains formed into a shrine of woody substance and left an egg behind. The egg hatched sometime later and Edel, in turn, raised the infant dragon as his own, naming her , which meant "the waters" in dragon language. As with Nova's "mother", both became inseparable as Edel grown into a young man and Nova grew into her adult form, spending their days together slaying Horrors, so much so that Edel had later taken Nova to be his "wife". The duo happened to save a human village one day from the Horrors, and finding it rather enjoyable saving lives, they somehow became heroes in their own right protecting humans from Horrors. Despite having fought Horrors and protecting humanity faithfully, a group of Makai Priests saw him as an abomination who was neither dragon nor human, and Nova a monster whose powers to be harnessed. This group abducted Nova when she was at her weakest--having after laid an egg not long ago, and set up a ritual to harness her powers. Edel eventually came to her rescue, but Nova was killed nonetheless trying to save him, slaying the group of Makai Priests and putting Edel in his suspended animation state in the process. 
Since then, he turned to be disgusted by humanity instead, with his first act upon awakening being to kill Okina, after being told to harness the dragon's powers to slay Horrors, as it reminded him of the nightmare long ago. Despite being a human, he claims to relate with the dragons better and sees himself as a dragon in human form. He sees humanity as nothing more than ugly, filthy vermin to be cleansed from the face of the Earth, and intends to do so once he gets his hands on the Dragon Egg. He is defeated by the combined forces of Rei, Rekka, and Kagome, being thrown into a chasm after Kagome sacrifices herself to defeat him. However, he is soon revived by the sacrifice of his mechanical fish-like familiar , and resumes his hunt for the Dragon Egg.

However, that is revealed to be a lie and Rinza had been using Banbi all along, cooperating so as to use the resurrected fallen Makai Knight as a tool to create and activate the Fang of God. Banbi is crestfallen once the ploy is revealed to her and the fallen Knight she resurrected is revealed to be Jinga instead of Judo, whom Rinza deems to be too weak for his intended purpose.

Azami grew into a talented Makai Priestess noted for being the only one who can control the darkness, and Monastery sought to use her dark gift for its own purpose. Little did the Order knew that the reason why Azami possessed such gift was because of her ensouled by the very fragment of darkness her father destroyed long ago, and now aimed to continue what it started.

The Grou Dragon.
The is the guardian of the Barankas fruit which it produces within its body. The Grou Dragon is a sentient mechanical dragon created to reside inside the Crimson Forest and hunt the Horrors there. He has a main dragon head on the top and four sides to his body (almost cube-like). His cube-like body has a rustic color and when he speaks he rotates it to a different side of his body. Whenever he reacts to some thought his body makes a turn. Two sides of his body have a white naked woman statue, the front side a white gothic skull of a creature, and the back side with just gears that resemble the yin/yang sign. The Grou Dragon has a blaster-cannon, his statues are actually large mechanical claws, his gothic skull is actually a claw and grinder, and his gear side has multiple mechanical tentacles. He has four mechanical legs and his back is capable of bringing out two large wings for flight. His only purpose is to destroy Horrors, the Grou Dragon's fangs are used by Makai Knights to hone their skills.
When the Grou Dragon first encountered Kouga when he needs the Barankas fruit to save Kaoru, he expresses being curious about the Makai Knight's nature to protect people and challenged Kouga to defeat him with all his strength to win the fruit. The Grou Dragon helped Kouga summon his armor and Gōten to fight at his full potential while engaging in a clash of ideals if saving lives is more important than destroying Horrors. Kouga almost lost to him, but Rei stepped in to assist him. Kouga thought he lost the fight because he had help, but the Grou Dragon said that if Rei lend his power to Kouga, then that's also part of his power.

The Makai Tree.
The are tree-like creatures that resides in the Makai Forest, products of the Horror Eyrith. One such Makai Tree kept Jabi within her stomach, which resembles as a round squid-like creature with multiple eyes. She has many tentacles and can shoot spears out of her "body" to defend herself. She's not a malicious creature; she kept Jabi sleeping inside her stomach for a 200-year incubation. She claimed that Jabi wasn't ready to reincarnate (hinting the Makai Tree had plans for Jabi) when Kouga came to save her.
Kouga at first had to fight off the Makai Tree's illusionary attacks. The Makai Tree has the ability to take on the forms of people within the memories of Kouga. For Kouga it as easy when Barago, Kodama, and Rei appeared, but the most difficult was when Kaoru and Taiga's form was taken. Eventually Kouga learned to suppress his feelings just long enough to defeat the Makai Tree on the first round. During the second round Kouga had Gōten increase the Garo Zanbaken twice its size and surfed the sword into the Makai Tree's stomach. The Makai Tree's stomach exploded and Jabi was saved.

The Spirit Beast.
The is a mysterious creature whose pelt is used as a material for making hairs of Madō Brushes, while it itself is the only creature that can restore a brush's fading power, though hunting down the Spirit Beast without permission is strictly forbidden. The Spirit Beast can usually only seen by extremely rare chance, and perception of its appearance differ from one person to another. Those who seek the Spirit Beast intentionally must possess a ceremonial blade and travel through a certain path in a certain manner, and remain untainted by evil qi along the way. The Spirit Beast exists in a different plane of existence, as such, a final ritual of synchronizing one's space-time with that of the Spirit Beast's is needed. Although the Spirit Beast is harmless, it is however, accompanied by a ferocious guardian beast called , which attacks indiscriminately anyone who intentionally gets near the Spirit Beast. To those capable of painting, there is also a custom of gifting a painting of the Spirit Beast as he or she perceives it, to the person one cherishes the most. Regardless of its appearance when fully grown, it appears as a sentient fur ball as a baby.
Zaji.
 is a manifestation created from the essence of many Horrors who were slain by the Makai Knights bearing the title of Garo; his appearance differs depending on the person inheriting the title. Because of his origins, driven by the Horror essence that composes his being, Zaji exists with the sole purpose to kill Golden Knights with extreme prejudice. Among his abilities is manipulation of time and space, using it to create a clone of himself and change the flow of time as well as the battlefield. Using a broken stone face from a sphinx-based Horror statue to gain physical form, Zaji challenges Kouga to a fight to the death. Once his identity is revealed during the fight by the will of the ancestors of Kouga taking form of the Golden Knight, Garo damages the statue's restored face to destroy the Horror Gate that enables Zaji to exist. Though defeated, Zaji points out that his kind will kill Kouga and his successors in time, and that Kouga shall not have peace until his death should he choose to walk the path of a Makai Knight.
Zaji appears once more in "", this time to face off against Kouga's son Raiga who has gone for purification while getting a new Grou Dragon's fang. As Raiga has killed his hundredth Horror, the fang became embedded in the nearby broken statue face holding the sealed Zaji, and the Horror latches himself to it. Once the fang is installed in the Saezima manor, Zaji proceeds to make attempts to kill Raiga at his home with two clones. Once personally facing Raiga, Zaji overwhelms the Makai Knight by revealing his ability to transform into , a large demonic version of himself. However, Zaji ends up being defeated by Raiga once again, right after he acquires the right to summon Gōten, which he earns due to the will of Garo reasoning that by fighting Zaji, he would be in fact fighting himself. Zaji curses the current Garo before exploding upon his defeat. But Zaji is revived once more by Eyrith, who offers him the chance to wipe out the Garo line by sending him a time-displaced Rekka and Rian who the being sensed to be tied the Garo line. Luckily, the women were saved from certain death by Kouga who was also displaced from the realm he ended up in after Eyrith removed him and Kaoru from their time.

Gajari.
 is a being within the Senate's walls that was created long ago by the Makai Knights' collective imagination as a protector of humanity. While more of a neutral being, seeing no distinction between humans and Horrors, Gajari only aids the Makai Knights due to a pact said to last for centuries. It is said that forming a pact with Gajari has consequences even if the reasons are pure, with Kouga making such a pact to stop Sigma and is forced by the deal to travel to the Promised Land to retrieve a part of Gajari's body: the Fang of Lamentation. However, Kouga learns that his quest was a means for him to understand the relationship between the Makai Knights and Gajari.

Barg.
 is a beast with several swords embedded in its back, which is capable of sealing Horrors inside its own body. Barg is used by the Shadowfolk Makai Knights as a means of purifying their blades. It is usually sealed in a deep well in a small shrine guarded by the Shadowfolk Knights and lays dormant. However, it can awaken from the slightest of physical disturbance, evident from being awakened when a young Knight peered into the well out of curiosity and a drop of his sweat landed onto Barg. It has a violent temperament and is powerful enough to kill Makai Knights, as well as sprout wings for flight. While it resents being sealed in the shrine and used as a tool, it cannot survive for long outside the shrine and will die in less than a day going outside.
When Barg escaped, Gento, Crow, and Raiga deem it necessary to slay Barg, despite the fact that it has less than a day to live, due to it having killed four Makai Knights. Slaying Barg proves to be troublesome as it cannot be simply cut down, due to Horrors sealed within would be released if Barg dies. Gento and Crow, the two remaining Shadowfolk Makai Knights present when it escaped, have to trap it under a temporary moonlight barrier before Raiga can move in to cut it down, so as to contain the Horrors sealed within it.
Mayuri easily empathizes with Barg, due to her being a Madōgu as well, and attempts to seal it within her at the risk of her own life. She is visibly saddened when it is cut down, and proceeds to put up a grave marker using one of the swords from its back.
Small Makai Dragons.
Small draconic fishes tamed and deployed by Makai Order as familiars for variety of purposes such as sensory detection, scouting, combat, and messaging. Usually summoner in swarms by Makai Priests, the creatures can either tearing target apart with their teeth like piranhas or detonate in rapid, destructive kamikaze attack; able to stay with its master/summoner for extended amount of time, or vaporizing back into Makai Realm to avoid death.
Makai Dragons.
Makai Dragons are entities originating from the Demon World and little is known about them, as only one was known to have been around in ancient times and no sightings of these creatures have been documented since the only dragon known died. According to Edel, dragons are very intelligent beings, evident from one capable of raising Edel himself from infancy and teaching him everything he knew about the world, including ways of slaying Horrors, which was virtually unknown at the time. The dragons also have their own language, with examples of "Edel" meaning "the lands" and "Nova" meaning "the waters". While capable of eating food from the human realm and even finding such food to be enjoyable, dragons sustain themselves solely through consumption of evil ki. They breed slowly, as seen in Nova's case where creating and laying an egg itself takes considerable time and effort, and severely weakens them for a period of time. They could also leave behind an egg when they pass, as seen in the case of Edel's first partner. As their name suggest, they are fearsome creatures of formidable power, with the example of an infant hatched not long ago sporting powers comparable to that of a Makai Priest with advanced combat magic, and teleporting elsewhere after using such powers.
Dragons are also emotional beings and are known to form deep attachments to those who are close to them. It is in their instinct to put their lives on the line without hesitation for the sake of their loved ones, even at infancy. Unlike most creatures hailing from the Demon World realm, they are not inherently hostile to humans, and one lone example have been shown to be fond of humans enough to save an infant sacrifice from Horrors and raising the baby as her own.
