Why is Demon King not leaving purgatory?
Why are there no frontal battles between the Demon King and the Supreme Deity (the goddess)?
Is there a rule to prevent that?

I haven't read/watched the series but the question in the spoiler seems like a different question. if it is then it should be removed and asked separately

I thought it may be related to the fact that demon king didn't make its appearance on Earth. I'm going to delete it though. Thanks!

There was a great war between the clans 3000 years before the current time in The Seven Deadly Sins. The two main clans on each side were the Demon and the Goddess clan. There indeed must have been battles between the Demon King and the Supreme Deity at that time however none of that is shown in the anime or the manga. At the end of the war, the Goddess clan basically ended up defeating the Demon Clan by sealing them away for good using the Coffin of Eternal Darkness. The seal was eventually broken partially by Hendricksen freeing the Ten Commandments and many other demons but it was not enough to revive the Demon King himself.
So basically, Demon King cannot leave the Purgatory. The Purgatory is a space between the living and the afterlife. It is similar to how Meliodas didn't move go to the afterlife and instead went to the Purgatory. So the Demon King isn't really dead but not much of a living being either. He is simply waiting for someone to revive him.

I'm really impressed by the fact that demon king can't break the seal. However, I found this: (spoiler alert) https://i.imgur.com/xdrRv6P.png interesting.

@ShadowXsc That's interesting. I guess I missed that. It does hint that he simply might not be able to stay in the world without somehow destroying. But I am fairly certain about the fact the fact why he's not leaving the purgatory.

It is not because he can't break the seal. Unlike most of the other demons, he was never sealed because he never actively participated in the war. He was stuck in Purgatory.
The answer is that he is simply too powerful. Meliodas mentions:

The Demon King's power is great. Which means I will most likely not be able to stay in this world, Britannia, anymore.

The Demon King would probably destroy Britannia by his sheer power if he stays there. That's why he uses Wandle to keep an eye on Meliodas, then when Wandle died, he uses Hawk.

Yeah. I pointed out meliodas' statement (see the comment of first answer). Why would he care if britannia is destroyed, he wants to win the war, so, with that much power why not go straight in for a win, or a death battle vs goddesses

What exactly is the Code Geass?
I have watched the series once and I believe there are quite a few things left unexplained. The powers for instance can be transferred to others by only the people who have the "Code" like C.C. or V.V.
So what exactly is this code? And was Charles after immortality when he tried to acquire C.C.'s code? He even acquired V.V's code didn't he? So he was immortal. Why was he after C.C.?

Related (if not duplicate): http://anime.stackexchange.com/q/19070/1587

So what exactly is this code?

If Geass is considered "Absolute"1 then the Code is "Absolute over Life" thus making someone immortal. This question has some answers on how it is different. the form the Code takes it unknown but we can assume that because Geass doesn't appear to have a physical and tangible form then niether does The Code

was Charles after immortality when he tried to acquire C.C.'s code? He even acquired V.V's code didn't he? So he was immortal. Why was he after C.C.?

Charles was already Immortal when stole V.V's Code so he didn't need C.C to obtain Immortality. as i explain in This Answer i suspect that the Sword of Akasha needs 2 Codes to activate

My own theory is that the Code made Charles untouchable as to activate Ragnarok originally required 2 Codes. (However after Lelouch saves C.C before Ragnarok is activated Charles is still able to activate it).

One thing to note is that in the debate of "Is Lelouch Alive", on the side of yes one theory is that Lelouch has Charles's Code (as C.C retains her Code). assuming this side one can speculate 2 things when Lelouch ordered Charles to kill himself when they were at the Sword

Charles pretended to be controlled and die knowing he was immortal
The Code wasn't activated until Charles died which is why when Lelouch tried to order him again we see it repelled rather than it just do nothing (eg. when Lelouch tried to use it on Kallen and the Teacher a second time early in Season 1)

1: if you look here and look at Lelouch's, Mao's, Rolo's and Marrybell's Geass their Geass powers all have "Absolute" in their names and if a Code Barer is Absolute to a Contractor's Geass (thus immune) then they could also be Absolute to Life given the power Geass has over others

Why didn't Ban look for Elaine instead of staying in prison?
In "The Seven Deadly Sins", after the Sins were branded as traitors and the holy knights took over, they each went their separate ways and into hiding. Ban was imprisoned eventually. He stayed there for years even though he could escape. He only got out when he got the word the Meliodas was out and looking for them.
Ever since he came out, he's been trying to look for a way to revive Elaine. I was wondering why he stayed in the prison for so long if he still had such an important thing to do. Why waste all that time when he could have looked for finding a way to revive her.

When Ban escapes from prison he explains that he allowed himself to be imprisoned because back then he craved pain.  This gave him, in a twisted way, pleasure but he grew tired of it. When he heard Meliodas was nearby, he escaped because following him would be more fun than being locked in a cell with bars through his limbs barely being fed.
It takes visiting the after life, having his team fight the resurrected Helbram, and fighting with Captain to decide to go out on his own to resurrect her.  He is obviously more than willing to take any opportunity to bring her back (even betraying his team) if he observes an opportunity.  This seems to indicate that he gave up for a while and did not pursue that goal because he did not know how to bring her back. He didn't seem to have a known way to bring her back but since going off on his own, he has started to search desperately.  I would expect he did the same before going to prison.
Keep in mind that, for an immortal man and long-lived fairies, 5 years isn't a very long time (even though it took much less time to fall for each other).  This was almost like taking a (pleasant?) vacation when he had no clear time constraint on his project despite it's obvious importance to him.  I would assume their was some guilty and self-contempt involved too.

I doubt that Ban could ever even think of relaxing and slacking off just because he is immortal and has all the time in the world. After the Sins were branded traitors and hunted, he had absolutely nothing to do. Now that he is out, he even leaves the Sins just to look for Elaine. If he is really that desperate, why would he waste so much time in the first place.
It seems to me that Ban knew about the "Horn of Cernunnos". Why wouldn't he look for it when he knew there was a way to revive Elaine?
I believe there might be better answers, so I guess I'll wait a little longer. Thanks by the way.

I guess it ties in with the fact that he wasn't looking for a way to revive her back before they were disbanded. It seemed as if he was looking for a way to keep her off his mind, while we tries to keep himself together. I agree with you though, it does seem a bit out of character if he were to be relaxing and slacking off. I believe at some point he does mention that being with Meliodas did help him keep his mind off of Elaine and helped him get himself together.
Also as a side note, being part of the 7 Deadly Sins was a huge time commitment. He probably did not have enough time to go looking around for the "Horn of Cernunnos". It would also make sense that he avoided the Horn if he knew it was in the Capital since he is wanted. As for why he locked himself up instead of looking for alternatives ways? It could just go back to getting himself together and being in the right mental state to cope with his loss. Ban is surprisingly very nonchalant when it comes to all of this, and it could be an effect of him training himself during this time.

What is the meaning of Rosario and why did Yuuki name that skill "Mother's Rosario"?
In the second season of Sword Art Online, Yuuki had an 11-hit Original Sword Skill. She passed it down to Asuna before she died. She named the skill, "Mother's Rosario".
Can anyone tell me what exactly is Rosario supposed to mean? I would like to know what it literally means and what it means in the current context and if there is any history behind the word.

According to Wiktionary Rosario comes from the word rosary which is connected to the roman catholic church. though i have no idea how this connects to Yuuki having not seen up to there yet but from what i have read Yuuki saw Asuna like a mother and with how rosary are used in Maria Watches Over Us where a rosary was only traded with a person you cared about i wouldn't be surprised if Yuuki named it that just for Asuna, a skill passed on to the mother Yuuki cared about

Konno Yuuki is heavily implied (if not outright stated? I forget) to be Christian, hence "Rosary". (Perhaps this is obvious, but I suppose for completeness, I should point out that "Rosario" is just the Portuguese cognate of English "Rosary". Many of Japanese's Christianity-related loanwords come via Portuguese.)

Yes it seems kind of understandable that Rosario comes from Rosary. But I really want to know the true concept behind this. It's a really catchy and touching name and I would really like to know what it means here. So Rosary is just some sort of prayer or incantation?

@Memor-X I think you've got it the other way around. I don't remember the exact words but when Yuuki passed it on to Asuna, she did say that it will keep you safe. So even though it might be sensible to say Asuna was somewhat of a mother figure to Yuuki, but Mother's Rosario was meant to protect Asuna. So in that sense, the mother who is actually protecting is Yuuki.

Yuuki's mother turned to Catholicism after learning about her and her family's affliction. This much I'm pretty sure was mentioned in the anime, and it left a strong impression on Yuuki herself.
The author said the skill name is a memento to her mother. (I'll need to find the exact quote later, but it was an answer to a fan's question on Twitter) He used "Rosario" instead of "Rosary" because the Japanese loan word was taken from Portuguese. A rosary itself is a set of prayers called "Hail Mary's". There are also ornaments like necklaces or rings with specific beads for counting the Hail Mary's, also called Rosaries. While it may be speculative, I also think that each hit from the 11-hit skill by Yuuki represents a physical rosary's components, as the typical rosary has ten beads each to represent a Hail Mary, plus a crucifix.

It seems to make some sense but something are still unclear. Can you explain these? Rosary also seems to mean a "garland of roses". Couldn't the word Rosario have any connection to that? Furthermore, the Hail Mary's that you talked about. What are they really for? Is it just some sort of tribute to Mary or do they believe that it offers some sort of protection? Because if it's just some sort of a praise to Mary, it wouldn't make sense that something like that would be of any use to the one saying it.

Can you explain why Rosary is related to the idea of protection?

I'm not an expert on Catholicism, but I assume most prayers are pleas for some sort of protection or assistance. I assume a Hail Mary is such a prayer, and a Rosary is a set of these prayers chanted in succession. I also wouldn't know how a rosary is connected to the idea of protection; I merely claimed that Yuuki's skill, the Mother's Rosario, was something like a memento to her mother.

Yes I have been doing a bit of research and it doesn't seem like it has anything to with protection, the Rosary I mean. It is somewhat of her mother's memento.

hey tsuf, at least look up wikipedia to write your answer, please? you got the prayers wrong.

I think the title "Mother's Rosario" comes from Yuuki's religion (or her mother' religion), the number of shots in her unique sword skill along with the gift she makes to Asuna.
"Rosario" is the Italian/Latin (no Portuguese) word used for a form of prayer in the Roman Catholic Church. In its short form, it consists in a sequence of prayers (one Apostles' Creed, one Lord's Prayer, three Hail Mary, one Glory Be) followed by ten Hail Mary that must be recited in a loop at least five times.
A necklace, called "Rosario" itself,  which is composed of a string of knots or beads is used in a hand to maintain sequence and count of prayers.   The necklace name is derived from latin "Rosarium"  which stands for "crown of roses" and, among the Catholics, there is the tradition of gifting these necklaces.
PS: I'm Italian and I'm Catholic.

It is portuguese. https://pt.wikipedia.org/wiki/Santo_Ros%C3%A1rio -  https://movimentojovensmarianos.wordpress.com/oracoes/como-rezar-o-rosario/ - it was portugese jesuits that brought catholicism to japan  https://en.wikipedia.org/wiki/History_of_the_Catholic_Church_in_Japan - the word has very few deviations from its latin roots in romanic languages, that is why it is spelled the same in italian.

Now it has been established on this forum that Rosario is Rosary. Yuuki gave Mother's Rosario to Asuna to protect her in the episode. Now in real life, devoted Catholics say the Rosary as a prayer. In fact the Blessed Mother Mary promises protection against hell to the souls who recite the Rosary.
So it can be interpreted that by naming the skill "Mother's Rosario", Yuuki was asking for the protection of her soul and the soul of many others. Therefore it could also be interpreted when she gave it to Asuna, she also asked the Blessed Mother Mary for the protection of Asuna's soul against hell. Catholics believe that Mary is a powerful intercessor and leads souls to God, that is why they ask for her prayers.
Now the Mother in "Mother's Rosario" is very likely to be referring Mary the Mother of God also known as the Blessed Mother Mary (also known by many different titles). Catholic Christians believe and accept that Jesus on the cross has given His mother to His believers. Yuuki is heavily implied to be a Christian, specifically a Catholic Christian, so the "Mother" could be very much be referring to Blessed Mother Mary.
So hence, the points I discussed previously could be a reason to why Yuuki named the skill Mother's Rosario.
I am a Catholic myself so I know the meaning of Rosary.

If you want the TL;DR version, just skip to the last paragraph.
This question is a bit easier to understand if you're Catholic or are knowledgeable in Catholicism. I'll try my best to help explain this as a Catholic myself. It might be long, but trust me, you will understand Yuuki/Zekken from Sword Art Online 2 a lot more if you take the time to read all of this. First, what is Catholicism? I think it's important knowing so that you understand Yuuki's decisions and thought process in naming her unique 11 hit combo sword skill. This might be a little long, but I think it's important to first give a quick crash course in Catholicism before I explain how it relates to Yuuki.
To start, all who are part of the Catholic Church are Christians. Catholic and Christian are synonymous, they are the same thing. To be Catholic means to be Christian. While there are other denominations of Christianity, it doesn't mean they are Catholics. All Catholics are Christians, but not all Christians are Catholic. Catholic means "universal" in Greek, which is used in Catholicism as representing "Universal Christianity". That is, Catholicism teaches the Christian faith to its fullest and most orthodoxy extent. Catholicism is both the original and oldest branch of Christianity, founded by Jesus Christ in 33 AD (Almost 2000 years old now) when he appointed the Apostle Peter as the first pope to look after his flock (Christians) in His (God's) physical absence. See to Christians, Jesus is God, and while he is no longer with us in the flesh (physical), he is still with us spiritually in the form of the Holy Spirit from the Trinity (Father, Son, and Holy Spirit). Although the trinity can confuse non-Christians thinking it's 3 gods, the trinity actually represents only one God. Christianity is monotheistic, which is the worship of the one and only God. Think of the Trinity as a 3 leaf clover/shamrock, which has 3 leaves, yet is still the one same clover. When a clover has 4 leaves, the 4th leaf is considered luck, which is where the belief in lucky clovers comes from.
Moving on, I think it's best to explain the Virgin Mary and the rosary now, which is called "Rosario" in Spanish. The Virgin Mary is very important to Catholics because she gave birth to God in the flesh, Jesus Christ. Mary is special because she was picked by God to give birth to Him in the flesh (Jesus Christ, the Son part of the Trinity). Mary then gave God permission to allow her body to give birth to God incarnate, Jesus Christ. I know, that may seem very shocking to non-Catholics, but Christians believe it to be true based on many miracles and many eye witness accounts as proof to Jesus' divinity as God in the flesh. Not to mention that Judaism (Jewish faith) prophesied this thousands of years before the birth of Jesus Christ. Christianity is the continuation of the Jewish faith. Mary's role in Christianity is to help guide all Christians towards her son and Lord, Jesus/God. Catholics consider Mary the ultimate saint, a one of a kind saint whose body was completely pure of any taint of evil/corruption, which was the perfect vessel to give birth to God in the flesh (God's human physical form). That is, Mary's body had the unique trait that allowed God to be reborn into his own creation. This is where the Rosary (Rosario) comes in.
The Rosary is used by Catholics as a form of prayer to recite the "Our Father" and "Hail Mary" prayers. The prayers that comprise the Rosary are arranged in sets of ten Hail Marys, called decades. Each decade is preceded by one Lord's Prayer and followed by one Glory Be. During recitation of each set, thought is given to one of the Mysteries of the Rosary, which recall events in the lives of Jesus and Mary. Five decades are recited per rosary. Other prayers are sometimes added before or after each decade. The crucifix represents the start of this 1+10 combo which results in 11. Rosary beads are an aid towards saying these prayers in the proper sequence. While the rosary form of prayer is not required to be a Catholic, it is encouraged.
Now we finally made it, time to explain how all that represents Yuuki's/Zekken's "Mother's Rosario" unique sword skill. In Catholicism, Mary is considered every Catholic's mother, and she is a huge part of the Rosary. If you combine this fact, you get "Mother's Rosario". One could also argue it has to do with Yuuki's mother, who we find out prayed for her family, especially her children, as evident by the flashback when Yuuki and her mother prayed in a church. Considering the mother was Catholic, it's extremely likely she prayed often with a rosary, making sense of the skill name being called "Mother's Rosario". However, there is actually more meaning to the entire "Mother's Rosario" arc in Sword Art Online 2. Remember how in one of the episodes Yuuki said she did not understand her Catholic/Christian religion when she was younger (shown in a flashback while she's praying in a church with her mother)? Well, that is very common among children in Catholicism since it is very complex. We grow to understand it more as we get older. While some come to understand their Catholicism from an intellectual level by doing tons of research through books and epistles of the Church, many others learn through the Christian concept of suffering. See, Christians believe that suffering has the potential to create good in some form that we cannot perceive at first glance with our limited human intellect. When we suffer, we often question the negative aspects of suffering, but sometimes, we are blessed by it after in some form. As an example, we'll use Yuuki's suffering, who contracted the HIV virus, which then formed into AIDS. This is shown during Yuuki's last few minutes before her death, when she says she finally understands why she went through all that suffering. In Yuuki's case, it was to experience "Love", true love in its purest form, but also to teach others how to love before her death. Also, remember that Yuuki and the Sleeping Knights (her guild where all members are terminal patients in real life) had a deep desire to immortalize their guild and name's in Aincrad's Monument of Swordsmen. The entire guild's suffering empowered them to achieve something that was deemed impossible by most players in the game. Now, that is not saying that Yuuki's suffering is a good thing, because it's not, in fact it's horrible! But her suffering did bless her to be loved and in return to love others, as well as give her the power to endure, yet enjoy her last moments of her life through in-real-life and in-game accomplishments. That is the meaning of the Christian concept of suffering. Another form of blessing from sufferings came after her death, in that Yuuki gave her guild mates of the Sleeping Knights hope and courage to fight their disease, where we are told that Shi-eun and Jun are recovering from their illnesses. Another blessing comes in the form that Kirito and Asuna figure out that Akihiko Kiyaba and his wife are behind the medicuboid technology, suggesting/implying that Kiyaba's reason to create the death game of Sword Art Online was to give Medicuboid technology a jump start for investors to take it serious in order for its technology to benefit mankind in the long run. Finally, Yuuki's suffering leads her to determine who she will pass on her "Mother's Rosario" to. She picks Asuna as its next wielder, to which Asuna tells Yuuki she will make sure the "Mother's Rosario" skill will be passed on to worthy players until the end of time, essentially becoming another unforeseen blessing, her "Mother's Rosario" becoming another permanent piece of evidence that she existed, essentially becoming another action immortalizing  Yuuki again in some form. Keep the thought of being "immortalized" on your mind because I will mention it one final time at the end of all of this. Now, the rosary (Rosario) is a 10 + 1 = 11 part of the Catholic rosary. The 10 represents the "Hail Mary" and the 1 represents the crucifix. Does this sound familiar yet? It should, it is a reference to Yuuki's 11 hit combo! Yuuki tells Asuna she named the 11 hit combo unique sword skill "Mother's Rosario" and that it will keep her safe when she needs it. This represents the "Hail Mary" prayer, which is known to be used during difficult or dangerous situations. The "Hail Mary" is a prayer requesting the Virgin Mary to intercede for us in asking for Jesus/God's help when we need Him most. This is the popular football play in the NFL, when player's go for an all-in difficult long throw, the famous "Hail Mary" pass. Makes sense right? Well now, think about when Yuuki uses it. Notice Yuuki only uses her 11 hit combo, "Mother's Rosario", when she is being overwhelmed by a skilled opponent, as evident to only using it against Kirito and Asuna when they managed to briefly overpower her. Yuuki's "Mother Rosario" is her "Hail Mary"! How cool is that?!?! Lastly, I said I would mention "immortalize" one last time. Yuuki is a Catholic Christian, meaning she believes in an afterlife after death. Christians believe in heaven, where they will be granted life everlasting in paradise, essentially immortality in a perfect body, without pain nor sadness, while living in peace and tranquility. Yuuki is looking forward to seeing her family again after her death, and during her dying words, she mentions that she is looking forward to the day that she gets to see all her friends again when they pass into the afterlife like her. This is overwhelmingly a Catholic Christian belief. Even if one is not a Christian, the Catholic Church teaches that even non-Christians have the potential to be granted entry into heaven by God, through the concept of "absolute ignorance". Briefly, "absolute ignorance" basically means non-Christians that are allowed into heaven because of reasons in life that prevented them from learning about or accepting Christianity before the time of their death. This means that all the Sword Art Online characters have the potential to be bound for heaven, even if they're not Catholic/Christian. Yuuki takes her last breaths in life smiling, acknowledging that her suffering lead her to these moments and realizations; lastly ending by saying that she gave it her all and that she was alive.

your "tldr" should be broken up into separate paragraph as it's a bit hard to read. you might also want to review it and take out anything that isn't related to the question as i am picking out stuff like suffering and blessing and not sure how these relate to the meaning and reason to naming the skill Mother's Rosario

Why did Mumei "need to go to the toilet"?
In episode 10 of Kabaneri, Biba (aka. the Liberator) visits the local lord. He takes his Kabaneri with him, including Mumei.
As soon as they arrive, Mumei claims she needs to go to the toilet, then uses that excuse to run all the way back to the station's gates and open them.
What I didn't understand was why Mumei needed to accompany Biba in the first place. Since opening the gates was part of a grander plan devised by Biba himself, wouldn't it have been simpler to just leave Mumei behind?
Even from a purely political point of view, there doesn't seem to be any reason for Mumei to act. Unlike Biba, she's not a particularly important (political) figure; she wasn't born in a particularly rich or notable family, and although she calls Biba "brother", the two of them aren't officially related. Her absence would likely have gone unnoticed by the lord and his retainers. And even if her absence had drawn attention...

 all of the witnesses would've been either murdered or kidnapped by Biba.

What was the point of taking Mumei along, then have her make up an excuse to run all the way back to the gates, instead of leaving her behind?

Because it would be weird if she separated from Biba at any other point. They were closely followed and in open while going in. So it would raise an alarm if they tried something funny.

And even if her absence had drawn attention... all of the witnesses would've been either murdered or kidnapped by Biba.

The point was not to draw attention until gates are open. If someone like Biba was just walking around it would definitely raise alarm. Someone like Mumei can easily stealth around and stun anyone who sees her. There is also added benefit of Biba staying with the "governor" distracting him.
And because only women and children were allowed to follow him inside (I assume because they believed women and children won't be a threat to soldiers), Mumei and the other woman were clear choices.

Does Devil Fruit taste bad?
In One Piece, some people were shown eating the Devil Fruit such as Sabo and 2 CP9 said it was disgusting or tastes really bad. However, Luffy was shown eating it at the beginning without a complaint. In the anime series, he ate it for being upset; in a movie, he ate it for dessert. Another case was Buggy the clown but he doesn't stand much of an argument because he technically swallowed it whole by accident. Also with Chopper: he ate it when he was a deer. It it really tastes that bad, wouldn't he follow his instinct as an animal and stop eating it?
TL;DR: Does Devil Fruit taste bad?

even if Chopper animal instinct is to stop eating the fruit that taste so bad, he actually still get the power of DF, since we don't have to eat entire fruit to get the power from DF

and you can check my question here

Chopper was outcast, solitary and hungy. His animal instinct told him to swallow whatever can keep him alive.

Yes, the Devil Fruit tastes bad. It tastes so inexplicably bad that is akin to poison as stated in the wiki about Devil Fruit.
Luffy has been shown in multiple different ways eating his Fruit in the manga, anime and movies. And also how he got his Fruit is different depending on the source.
The main point is that, in almost every case, a person eats the whole Fruit either piece by piece or by swallowing it whole.

They don't need to eat the whole fruit

That isn't the question.

If you mention it in your answer, then be correct.

If you have a more correct answer then post it.

Is Ritsu really necessary?
Ritsu was great when she was first introduced, but as I go on with the series, she seems to be a little less useless every time I see her, and then in the past few chapters, she was just gone. Is she truly a great help? When they went to that one place to make a major Assassination attempt, I noticed that Ritsu didn't take part at all. So what I'm asking: is she a necessary component of the class?

Bear in mind that there are a lot of students in E-class, and as such the author has the tendency to rotate characters in and out of focus. Ritsu has her moments in, for example, the Assassination Island Arc and the God of Death Arc (not gonna discuss in depth to keep the answer spoiler free.) The only students that have more of a consistent focus are Nagisa and Karma.
To answer your question, her necessity as a component of E-class is more or less equal to any other supporting character, for example Ryouma Terasaka.

Why are some of the names written in the Latin alphabet in Hunter x Hunter?
In chapter 199, Gon and Killua's names are written  the Latin alphabet on the blackboard.

In chapter 45, Killua and Zushi's names are also in the Latin alphabet.

Most of the writing uses the Hunter x Hunter alphabet, so why are these names written in the Latin alphabet? Is it just another language that is used in Hunter x Hunter world? If so, is there an anything that indicates where the Latin alphabet comes from in the world of Hunter x Hunter?

There's more than only Hunter language in the world, and romaji (or directly English) is one of them.
Do you remember Leorio mentioning that the phone Beetle can translate over 100 different languages? Hunter world most likely has the same languages of the real world, and many more are not shown yet, so far the Hunter language is the only invented one that we could see in both anime and manga, that's the reason of why in the manga we could see Togashi using the romaji/English writing.
However, I guess that the image you provided was edited by a fansub, as the original name of Zushi as for Official Hunter Databook (done by Yoshihiro Togashi) is written as Zooci (in Japanese ズシ, romaji "Zu-shi") and not Zushi. In the 1999 version, you see how the name Zushi is written in the score screen as Zooci. I don't think that Togashi would name Zushi as "Zushi" in some part of the manga when he intentionally wrote his English name as "Zooci" in his databook, it's pointless.
There are more cases where English was used instead of Hunter Language although I don't remember all, but we can assume that Hunter World has two major languages, and these are Hunter and English.

Most writing in HUNTER x HUNTER is in a syllabary, rather than an alphabet, that correlates exactly to the syllabary of the Japanese written language (hiragana and katakana).  A syllabary is a set of written symbols that represent the syllables which make up words; a symbol in a syllabary is called a "syllabogram."  (In contrast, an alphabet is comprised of letters.)
Romaji is the application of the Latin script to write the Japanese language, not the Latin script itself. In romaji, 「キルア」 would be written as Kirua.  Romaji does not include the letter "L."
Thus, these scans you provide show a language that is most likely English, based on the inclusion of the English word "To."  It appears that "Killua" is the intended English spelling of 「キルア」.
The syllabary is the primary written language of the HUNTER x HUNTER world and is therefore used on official documents, etc. but it is not the only language that exists in that entire world. Since キルキゾルデイック's useful answer was unfortunately deleted from this SE, I will also add here キルキゾルデイック's answer that Leorio's cell phone, the Beatle 07, boasts a translation tool that can translate over 200 languages. If a person never or rarely comes across other languages in the HUNTER x HUNTER world, a translation app would not be a useful feature that customers would fork out 200,000 Jenny for; that this is valued as a feature of the phone implies that it can be very normal to come across written languages other than the syllabary.
Although there is no stated reason for the inclusion of English specifically in the HUNTER x HUNTER world, the world includes linguistic elements that are shared with or based on our real world, which make up at least a portion of the 200+ languages that are stated to exist.  Just as if you visit Japan and see that most documents and signage are printed in the official language (Japanese), that does not preclude any Japanese person from writing something in English, or French, or Arabic, if they so desire at any given time; the person writing does not need to provide a specific rationale for this to be considered normal behavior.  In the same way, the HUNTER x HUNTER syllabary is what we see most often in that world, but since it is not the only language which exists in that world, any character at any given time can opt to write in another language that exists in that world, according to his/her personal preference.
For an example of the HUNTER x HUNTER world unapologetically employing English and other languages from our world, ヨークシンシティ (Yooku Shin Shiti = York New City)'s name is based on New York City, in a combination of the Japanese katakana pronunciation of "York" (ヨーク), the native Japanese word for "new" which is 「新」(shin), and the Japanese katakana pronunciation of "city" (シティ).
As another example, the character ハンゾー (Hanzo) is from the 国家 (kokka = nation) of ジャポン (Japon), which is clearly based on Japan, since he is the only one who knows how to make 寿司 (sushi) in the ハンター試験 (Hunter Exam) and he bears a ninja motif. "Japon" is an exonym for the nation of Japan.  An exonym is the name of an ethnic group and where they live, which is applied to them by outsiders (in contrast to endonyms, which are the names used by the group itself, such as 「日本」[nihon], 「日本（にっぽん）」[nippon], 「大和」[yamato], and「和」[wa]). The English word "Japonism" comes from this exonym.
As a third example, Gon's primary attack is ジャジャン拳 (Jajanken), which relies heavily on the Japanese words employed in the Japanese version of the originally Chinese game じゃんけん (Janken, known as "Rock-Paper-Scissors" in English). The game starts with the phrase 「最初はグー」("saisho ha 'guu,'" meaning "first comes 'rock'"), which is necessary for Gon to say aloud in order to power up. He uses the Japanese words 「グー」(guu, which correlates to 「石」 [ishi = rock]),「チー」(chii, which correlates to 「鋏」[choki = scissors]), and「パー」(paa, which correlates to 「紙」 [kami = paper]) to vary his attack.
As a fourth example, Netero wears a baseball tee with the Japanese or Chinese word 「心」 (kokoro) on it.  Some characters, including Netero, have names with origins in languages from our world (his first name is アイザック [Isaac], the katakana pronunciation of the English pronunciation of the Hebrew name יִצְחָק [Yitzchaq], which means "he laughs").
Thus, this case is not out-of-place according to the worldbuilding that the mangaka, Togashi Yoshihirou, crafted.  Rather, it fits with his precedent of including spoken and written languages other than the syllabary in the HUNTER x HUNTER world.

I don't think this helps to answer the question. The question is about why the names are not written using the in-universe language, not about how the in-universe language is constructed or the origin of characters' names. (Only one sentence in these 7 paragraphs attempts to address that.)

I think romaji can be used to refer to the latin alphabet. or at least me and the people I know do.

@eha1234, to see what the word "romaji" means, check the Oxford or Mirriam Webster dictionaries; for more detail, see Omniglot. There are 3 main romaji forms: Hepburn, Kunreishiki, and Nihonshiki. The word "romaji" cannot refer to the phrase "Latin alphabet" because the Latin alphabet is employed by a variety of languages, whereas "romaji" refers only to romanization of Japanese. Romaji doesn't include letters like L, V, & X.

What steps did the Yotsuba family take to keep the Shiba siblings hidden from the other families?
One thing I did not get at all is how the Yotsuba kept the siblings' very existence hidden right under the noses of the other families and the public.
I would expect all of Japan to be constantly buzzing about the Ten Clans' heirs, like the world gossips about the succession line of the British crown.
Some thoughts to consider about the Shiba siblings:

Their mother's wedding could not have been in secret. Even if it was a discreet event, it would be easy to find out that she married.
In their childhood, they were part of the Yotsuba family, who could not have erased their existence from public records.
Tatsuya's connection to FTL was never hidden. His shared surname with the company's CEO should have drawn some suspicion.
Who is the heir apparent to the Yotsuba at the time the siblings attended high school? The Yotsuba, a member of the Ten Clans, would have needed someone to fill the gap in order to keep their image.

I don't know if this was left unexplained in the light novels, but it is completely handwaved in the anime.
Juumonji Katsuto even seems suspicious of Tatsuya when he asks him if he has some connection to the Ten Clans (right before suggesting betrothal into one of them).

To an extent, this is also handwaved in the light novels as well - the specifics of how the siblings were/are protected are not disclosed. However, there are many references to the Yotsuba family's incredible power and influence, which allows us to infer - to a certain level - what's going on.

While the Japanese public may well have been interested in the heirs of the "10 families", the Yotsuba are a special case. More so than the other clans, (such as the Ichijou, Saegusa and Juumonji) the Yotsuba are an inherently secretive family, even before considering Tatsuya and Miyuki's special case:

"Because the Yotsuba Family, who maintain a systematic policy of secrecy, would never invite a large number of outsiders as guests... the siblings had brought themselves to the mountain village that was not recorded on any map..."
Volume 8 - Reminiscence, Chapter 1

And

[...] not even Miyuki knew the number for the direct line. The information control surrounding the Yotsuba Family was several times more intense than the government, and that was no idle exaggeration by those in the know.
Volume 9 - Visitor I, Chapter 6

Prior to the sibling's enrollment at First High, they too would have naturally been caught inside the familial policy of secrecy, meaning their chances of being discovered by outsiders was slim. Even during this time, Tatsuya is under strict instruction from his mother to remain inconspicuous:

"Tatsuya, it’s as you heard. You’ll be accompanied by Miyuki san on your tour of the base."
"Yes."
"Just keep one thing in mind. In public, don’t go using honorifics or the like when addressing Miyuki-san. Rather than ‘Ojou-sama’, just ‘Miyuki’ is fine. Actions which could lead to the discovery that Miyuki-san is a Yotsuba Head successor are prohibited."
Volume 8 - Reminiscence, Chapter 9

In addition, the military assists the Yotsuba in keeping Tatsuya's existence under wraps, as his power as a strategic-class magician is important for them to guard as well:

"It is most likely some of them will link this with the annihilation of the fleet the Great Asian Alliance dispatched three years ago. It would be a very undesirable outcome for us to have Tatsuya-san's identity to come out."
"I fully agree."
Seeing Kazama's nod, Maya gave a broad smile indistinguishable between real and fake... Maya's negotiation with Kazama was steered to obtain the most satisfactory result for the Yotsuba.
Volume 8 - Reminiscence, Chapter 15

Working in collaboration with the military by extension means working with the "Electron Sorceress" Fujibayashi Kyouko , who can manipulate electronic information to an unfathomable degree, creating an almost watertight seal around the siblings information.

This leaves a situation where even Kokonoe Yakumo, a renowned information broker, cannot uncover any of their background information:

Tatsuya squinted his eyes.
  "Our situation as well?"
Yakumo laughed heartily.
  "I've inquired into it, but wasn't able to unearth any noteworthy secrets.
  The intelligence manipulation surrounding the two of you is truly
  invincible. Or should I say, worthy of its high reputation."
Volume 2 - Enrollment II, Chapter 9

The same is true for the information network available to the Kitayama family:

In response, Tatsuya received it with a magnanimous look.
“Who the devil are you? With Kitayama’s…… The information network from the “Corporate Alliance” couldn’t even find your Personal Data!”
Volume 12 - Double Seven, Chapter 2

When it comes down to it though, the people that have the power, influence or luck to uncover the truth about the two would be too scared to both continue their investigation or disclose the information to anyone else after hearing the name 'Yotsuba':

The Yotsuba name had even more impact than the Saegusa name. The political utility of the Saegusa name was higher, but the Yotsuba name incited much more fear in people with influence.
Volume 12 - Double Seven, Chapter 6

This fear is also shown when Erika stumbles across Tatsuya's secret accidentally, and warns her brother against investigating him too much:

“I see…… I understand. Then let’s proceed along these lines.”
……Fortunately, she was able to convince her brother without dropping the name “Yotsuba”.
Volume 11 - Visitor III, Chapter 15

Even those not in the higher echelons of magicians should be rightfully wary of the Yotsuba family - after all, this is the clan that previously took down an entire nation in under 2 years! Furthermore, at present, they're quoted as being even stronger than then:

[...it] was utterly incredible that they could have forgotten such a harsh reminder in the last 20 to 30 years. Not to say the might of the Yotsuba Family – “might” that hinted at influence but was more along the lines of violence – was far greater now than it was in the past.
Volume 11 - Visitor III, Chapter 15

For the points you raised:

This isn't covered in the light novels, so I can't reference anything in particular, but given the other information, it's safe to assume that anything the Yotsuba wanted to keep secret (like children from a marriage) could be kept secret.
Their existence isn't erased, but all the data relating to them has been heavily modified, to the point where only the bare essentials are available, and there's nothing that could link them to the Yotsuba:

"After all, I can’t attend high school without Personal Data.”
Tatsuya’s answer made perfect sense. However, Benio felt that this was the rub.
“Please don’t underestimate adults. It is true that your PD has the lowest level of information, interlaced with extra information that complicated the picture and a few negative reviews, so it wasn't overly perfect."
Volume 12 - Double Seven, Chapter 2

When involved with FLT, Tatsuya goes by the alias 'Silver', and not his family name 'Shiba', which would help against identification from most staff or customers. In addition, while FLT is "owned" by Tatsuya's father, it's actually under Yotsuba jurisdiction, meaning they would have a careful eye on the situation, especially Tatsuya's colleagues who would be more likely to accidentally uncover sensitive information.

Like FLT, this hotel was one of the dummy corporations that was controlled by the Yotsuba Family in the background.
Volume 10 - Visitor II, Chapter 9

At the time the siblings are entering high school, there is currently no selected Yotsuba heir. If you recall back to episode 9 of the anime, Tatsuya chastises Aoki for calling Miyuki the next head, even though there has been no announcement regarding that position. Given Yotsuba Maya is also regarded as one of the world's most powerful magicians, I doubt anyone would be pressuring her too much for a decision. Additionally, as referenced earlier in the answer (quote 3), it seems they want to keep Miyuki's position a secret to outsiders for the time being.

I would like to add on a few explicit details.
1) Yotsuba Miya (Tatsuya's mother) is officially dead after 20 years of hospitalization, having never bore any children.
This is evidenced by Angie Sirius's thoughts in the Visitor Arc, where she claims the only person capable of alters the structure of the mind is dead, and never had any children.
2)Tatsurou (Tatsuya's father) and Miya most likely married in secret, after which Miya took on the Shiba last name. The children, having the Shiba last name, was basically a part of a nondescript family.
3)Tatsurou used a business name as the CEO of FLT. The Light Novel never explains whether or not Tatsurou's personal name can be found out. Assuming it can (This is unclear in the novels; Tatsuya's Personal Data does include who his father is, but I'd guess, for various reasons, that it does not show a CEO of FLT as his father), Shiba could be a common last name (though it would be suspiscious.)
Even if Tatsuya can be traced to be the son of a CEO of FLT, that doesn't say very much about him. FLT is not officially affiliated with the Yotsubas, and even if it was, it does not mean that the CEO is a Yotsuba, or has any relations to the Yotsuba.
4) There is none. The Yotsubas do not reveal this information, and no one can force them to. In fact, the only known member of the Yotsuba group is Miya and Hayama.
I would like to add on that despite these measures, Retsu Kudou still know about Tatsuya and Miyuki.

What is the meaning behind the Episode names for the original season, Träumend and Ouvertüre?
In original season, Träumend (season 2) and Ouvertüre (prequel OVA) each episode has a strange name such as Fräulein Rose (Season 1 Episode 1), Rozenkristall (Season 2 Episode 1) and Ewigkeit (OVA Episode 1). About the only ones I understand are from Season 2:

Episode 2 Enju which is when I think Enju is introduced
Episode 12 Alice

 being the final battles to determine Alice

I am wondering what is the meaning behind these names?

I have not seen the OVA and do not have acess to any of the episodes. So I can't really help connect the meaning of the titles to theyr episodes.
Those names are in german, and perhaps not very good german.
Fräulein Rose being composed of Fräulein, which is an outdated word for a young or unmarried woman (Wikitionary says the word in now avoided and considered disrespectful and sexist) and the word Rose, which does means rose, meaning something like "Young Lady Rose" or "Young lady of the Rose". Probably meaning Shinku.
Rozenkristall is a result of the word Rose being turned into an adjective for kristall, which means "crystal".
The word would mean "Crystal Rose". Which is the meaning of "Barasuishou".
Ewigkeit means Eternity.
Träumend means Dreaming.
Ouvertüre is Overture, no secrets, as the OVAs are a prequel.
I suggest using google translator for any other german title you find in the series, as it seems to be the theme used by the producers.

That's "Rose Crystal", not other way around in both Japanese and German.

Well, none of the names are truely strange, they are merely German ;) Going by the episode lists on AniDB which I remembered to be consistent with the titles I saw on-screen the titles and translations are:

Fräulein Rose — Miss Rose or Lady of the Rose; likely a reference to Shinku. Her appearance.
Kleine Beere — Small berry, Hina-ichigo’s translated name as far as I remember. Her appearance.
Mercury Lampe — This is nonsense in German. A mercury lamp (also Suigintou’s translated name) would be Quecksilberdampflampe. But that is long and doesn’t sound poetic, (as nothing containing Quecksilber does) so they probably decided to just translate lamp to Lampe. The reference is, of course, Suigintou’s appearance.
Jade Stern (should be Jadestern in proper German) — Jade star. Suiseiseki’s translated name and the episode in which she appears.
Die Treppe — The stairs. You remember that horrific filler episode, don’t you?
Tränen — Tears. Contrary to the earlier episodes I don’t quite know what this refers to.
Träume — Dreams. Because of the dream Shinku is in.
Lapislazuli Stern (should be Lapislazulistern in proper German) — Lapis lazuli star. Souseiseki’s translated name and the episode in which she appears.
Die Gefängnis — The prison. They got the article wrong, it should be das. I don’t know why none of the production crew could look the word up in a dictionary when they did so well with everything else (even umlauts). But whatever. The title of course references the prison the dolls and Jun are in in Souseiseki’s master’s dream.
Abschied — Farewell, preparing for Shinku’s departure into the N-field.
Schicksal — Fate. Because of all the fate that is involved.
Reiner Rubin — Pure ruby. Shinku’s translated name.

 Because it is all about Shinku, repairing her and her intermediate win against Suigintou.

Rozen Maiden Träumend: (träumend is dreaming)

Rozenkristall (should be Rosenkristall) — Rose Crystal. As was said, this is Bara-Suishou and her appearance episode.
Enju — Erm, yeah, it’s a proper noun. We get to know him.
Kanarienvogel — Canary. This is the episode where we get to know the canary yellow doll Kanaria.
Vereinbarung — Contract.

 Because Suiseiseki enters one with Jun.

Der Brief — The letter, because both Hina-Ichigo and Suiseiseki copy Souseiseki in writing letters of thanks and the episode centres around this.
Engel — Angel. This is the episode where Suigintou meets Megu.
Teegesellschaft — Tea company (could be both the people around you and the firm — like in English). Kanaria manages to ‘persuade’ the other dolls to join her master for a tea party.
Puppenmacher — Doll maker. This is where Jun starts visiting Enju to watch how dolls are made.
Der Tadel — The reproach.

 There’s quite a lot of criticism going on from one side to another — it’s practically the first Alice game episode. I’ll let you choose who is being reproached.

Tomoe — well, okay ;).

 The one where Hina-Ichigo gets to be with Tomoe one last time.

Rosengarten — Rose garden.

 A reference to the dolls’ fighting grounds.

Alice — yeah, you got that.

Rozen Maiden Ouvertüre: (Ouvertüre is overture)

Ewigkeit — Eternity. I don’t quite know why this name was chosen, but maybe just because it sounds cool.
Eitelkeit — Vanity. Possibly because this episode shows us the source of Suigintou’s pride in herself.

Is the manga Emma a retelling of Jane Austen's novel?
I haven't read either, but was wondering if the manga Emma is the same as the novel by Jane Austen under the same name.
They have several similarities:

They're both set in Victorian England.
They both have the same title
They are both romance stories

Jane Austen is a famous author, and it's conceivable that someone could adapt her novel into a new graphic format. However, none of the descriptions I've read of the manga mention Ms. Austen.
Are the series related?

...Jane Austen was a famous Author.  That's not a lot of similarities.  Emma in the anime is a maid, but in Jane Austen's novel is a privileged rich girl.

Sorry, autocorrect didn't like my British spelling. I think having same title and setting and theme is pretty similar.

It's a reasonable question (see Gankutsuou: The Count of Monte Cristo), but I think the answer is no. Note that I also have not read either work, but from looking at the Wikipedia articles for the manga Emma by Kaoru Mori and the novel Emma by Jane Austen:

The manga Emma is set in 1895 in the Victorian Era. This is much later than the novel Emma, which was published during the Regency Era in 1815.
One of the defining features of the title character in Jane Austen's novel is that, unlike the heroines of earlier Austen work, she is independently wealthy and runs her own household. The anime's Emma is a commoner, kidnapped as a child for a brothel, who escaped to the streets and was taken in and brought up as a maid by a wealthy family. She is a diligent and hard worker, whereas Austen's Emma was described by Austen as "a heroine whom no one but myself will much like" and is said on the Wikipedia article to have "a strong sense of class".
Anime's Emma lives in London, whereas Jane Austen's Emma lives in a small country estate in Surrey.

It is possible that the manga's author, Kaoru Mori, incorporated some influence from Austen's work, since she's a self-declared Anglophile,

The author and illustrator of the manga, Kaoru Mori, is a self-professed Anglophile, [...]
(Overview - 2nd sentence)

But overall, it doesn't look like a direct adaptation of Jane Austen's Emma.

If there is any relation between the two, it is scarce at best. While I didn’t read Austen’s novel, I watched the anime adaption of Emma, the manga. A pretty long scene (I would almost call it a key scene) is set in the Crystal Palace which was built for the 1851 Great Exposition. Austen’s novel was published in 1815; way before anybody even thought of the palace.
It would be conceivable that some other publicly accessable exhibition site housed a similar scene in Austen’s novel, but then why go such great lengths transferring the entire scene and thus the entire work to a point in time decades later? I think it’s just way too unlikely; that’s not really the kind of thing you do when adapting a story.

That's a yes but also a no. Very interesting that both are set in England in the 19th Century.
On the side of yes, there is a manga that is a direct adaption called Emma: Manga Classics by Stacy King (who performed the adaption), Jane Austin (who of course wrote the original story, and Tse (who was the illustrator)
By contrast, the series of manga simply titled Emma by Kaoru Mori is a completely different English tale from a similar time period but about 50 years removed.

Hope that edit will suffice, I had gone the link route as someone down below got down voted for not having sources. I also can't share any info from my own experience as I've read neither. I only learned of the manga a few days ago and decided to research it as I'm kinda obsessed with maids. :P

are those links supposed to be redirecting to amazon?

@UglyTrapMaid looks better! :) yeah, there's a recipe for a good answer on Stack Exchange: textual explanations and sources. Without "textual explanation", the answer will be deemed as a link-only answer and it is not a good idea to make the reader needing to check the link to know the detail. However, without "sources", it'll be harder to convince the reader if the answer is correct or not. Including both of them will mostly ensure a good answer :)

Actually, there is a manga named Emma and which is based on Jane Austen's novel, and it's from an artist Yoko Hanabusa.
I think you're confused because there are two mangas and animes with the same title and pretty much nearly everything else but the role of the major character.

Do you have a source for this statement?

They are not the same at all.
I have read the novel and I watched the first 2 or 3 episodes of Emma. It's like saying Michael Jordan and Michael J. Fox are the same because they have the same name.

Welcome to Anime.SE.  Could you elaborte this answer (and maybe remove the insult)?  We like answers on this site which are well explained and reference the source material or other canon sources.  I would suggest you read the tour page.  Again welcome and I hope you continue to contribute.

What are the differences between visual novel, eroge, gal game, and a dating sim?
In The World God Only Knows, games in which you conquer girls are defined as dating sims. But in Oreimo, it is called eroge. Some forums seem to use the term visual novel a lot, even though I thought they're all similar.
What is the actual difference between each of these?

All of these are closely related and many games would fall into more than one category. However, which word you choose places the emphasis on different aspects of the game. In any case, when it isn't important to be precise, these terms are often used interchangeably.

Eroge (エロゲ) is a Japanese shortening of "erotic game". These can also be called H-games. Native Japanese speakers sometimes use the term to describe games without any sexual content (e.g. Clannad), but in English this isn't really a correct use of the term. Eroge can be any game with sex scenes (also called H-scenes). This includes some games that are not traditionally included as visual novels or dating sims. For example, Kamidori Alchemy Meister is an example of a game without a great deal of visual novel content but which still qualifies as an eroge.

Visual Novel (ビジュアルノベル), often shortened to VN, is a general type of game with a lot of dialogue and minimal gameplay (usually the gameplay is reduced to just making choices at a few plot points to determine what route one enters). It may or may not involve any romance or sexual encounters. For example, Danganronpa could qualify as a visual novel, but probably not for any of the other categories here. A more canonical example would be Higurashi no Naku Koro ni, though purists will sometimes insist on calling it a "Sound Novel" as this is the official description. More on this in the related terms section. Calling something a visual novel emphasizes the "novel" aspect and suggests that there is at least some semblance of a story. It would not usually be used to describe eroge which are solely sex scenes.

Visual novel can also be used in a more technical way to describe games where the text is overlayed over the background as opposed to being presented in dialogue boxes. This distinction is more common among Japanese speakers than English speakers. In English usually people will abbreviate this as NVL, and games where the dialogue is in a box at the bottom of the screen are called ADV. Fate/Stay Night is an example of this style.

Dating Sims are a different category of game from Visual Novels. These games do feature gameplay, but the object of the gameplay is to get into a romantic relationship with a character from the game. The most familiar example is probably the Tokimeki Memorial series, though there are many other highly successful examples such as Love Plus. Unlike visual novels, the gameplay here can be fairly complex.

A galge (ギャルゲーム) or bishoujo game (美少女ゲーム, lit. "beautiful girl game") can be used to describe any game where a major part of the game is getting into and being in a relationship with one or more of the female characters (usually not at the same time). These are marketed at heterosexual males. It includes a lot of games that would be classified as dating simulators and a lot that would be classified as visual novels. Most games that would fit into this category would also fit into one of the other categories, though there are examples like Gal*Gun which probably can only fit as galge.

There are a lot of other closely related terms that could be used to describe these kinds of games. I'll describe these briefly here:

A Sound Novel is a type of visual novel. The term is a trademark by Chunsoft and emphasizes the sound aspects as opposed to visual aspects. Sound novels are actually older than visual novels but because of the trademark the term "visual novel" is the one that's stuck in the long term. For older games the distinction between the two is somewhat notable, but for most modern games there's basically no difference between the meaning of the two terms.
A Kinetic Novel is a type of visual novel without any gameplay at all. That includes things like making decisions for the protagonist. Because of the lack of any player input, the story is entirely preset and the player just reads through it without any input. These are quite close to ordinary novels with added graphics, sound, and typically more focus on dialogue. Planetarian would be an example of such a game. Kinetic novels are usually shorter than other visual novels, though there are exceptions to this like Higurashi.
An Otome Game (乙女ゲーム) is a game marketed to females. It is roughly synonymous with the term Bishounen game (美少年ゲーム), which is of course directly analagous to bishoujo game except now the characters are males rather than females. A well-known example is Hakuoki.
A nakige (泣きゲー, literally "crying game") is a type of visual novel where the story is designed to have an emotional impact on the player. Most games by studio Key are nakige (e.g. Clannad). A related but distinct term is utsuge (鬱ゲー, literally "depressing game"). Unlike nakige, which usually have happy endings (though they may be only after significant hardships), utsuge are usually not as positive. The distinction is difficult to explain, but after playing a couple of games in each genre you'll definitely know. Some notable examples of utsuge would be Saya's Song or recent Key work Rewrite.
A nukige (抜きゲー, literally "masturbation game") is a type of eroge which is almost solely focused on sexual content. As the name suggests, they're intended as pornographic material. It would be unusual to describe such games as visual novels.  These are the large majority of all eroge produced because they're easy to produce and still tend to sell well.

There are other terms but these are the ones that everyone should know when it comes to categorizing these sorts of games.

"Native Japanese speakers sometimes use [Eroge] to describe games without any sexual content (e.g. Clannad)" ... Why?

@LoganM I though Eroge is "Erotic Game" ? why would someone named that Eroge as a game without sexual content but the word eroge is "Erotic" ?

The four are loosely defined as follows:

A visual novel is an interactive game which is primarily a narration that uses still images to convey a scene or character; these two components make up the parts of the name, "novel" and "visual" respectively.
The word eroge is the Japanese term for any erotic (or, I believe, hentai) game; I believe the name comes from erochikku (ero-) and geimu (-ge).
A galge (gal game or bishoujo game) is a game which focuses on relationships or interactions with pretty girls (bishoujo). It need not involve sexual or erotic scenarios.
Lastly, a dating sim is any game, though usually Japanese, which focuses on romance and dating (a simulation of these things, as the name would suggest).

These terms are quite similar but carry distinct differences, as above, and there are times when they are incorrectly substituted for one another (dating sims are often referred to incorrectly as visual novels).

Can someone stop the cause of death after someone writes the details in the Death Note?
Let's say I had a Death Note. If I wrote someone's name in the book and then wrote details of the death, can an individual stop the cause of death and the actual death entirely or will the death still take action, but in a different way?

What do you mean by can an individual the stop the death? How would they do that?

The Rules of the Death Note are pretty clear:

How to Use: XI
[…]
As you see above, the time and conditions of death can be changed, but once the victim’s name has been written, the individual’s death can never be avoided.

This is, of course, as long as you thought of the victim’s face while writing the name. In case you now assume that you can just alter the details of death to something impossible, well sorry:

How to Use: LV
[…]
In the occasion where the cause of death is possible but the situation is not, only the cause of death will take effect for that victim. If both the cause and the situation are impossible, that victim will die of heart attack. [emphasis mine].

So again, all you get is a heart attack. The victim will die.
Tl;dr: Think before you write.

If you can change time and conditions, couldn't you do strikeout what you wrote before and replace it with In t+50years, dies of heart attack.

Rule XV states that

When the same name is written on more than two Death Notes, the note which was first filled in will take effect, regardless of the time of death.
If writing the same name on more than two Death Notes is completed within 0.06 seconds, it is regarded as simultaneous; the Death Note will not take effect and the individual written will not die.

So, if an individual is very, very fast he can save another from being killed by the Death Note (if you have two other Death Notes); this can happen as a very unlikely coincidence. But this rule states that "writing the same name (...) is completed within 0.06 seconds", so to save another life you need to write the name in the other two (or more) Death Notes soon after the name was written, and so before the causes of death.
So it's a task for The Flash... or maybe for Cyborg 009 since this is the Anime & Manga Stack Exchange.

In the occasion where the cause of death is possible but the situation is not, only the cause of death will take effect for that victim. If both the cause and the situation are impossible, that victim will die of heart attack. (Rules of the DeathNote. How to Use: LV)

So, hypothetically speaking, if an individual's name was written in the DeathNote and they were able to bring about events that would render the situation of their death impossible, they will still be susceptible to the cause of death.
However, there are no rules that specify what would happen to the victim of they were able to prevent the cause of death (be that if the cause was "shot through the heart" and the victim locked themself in solitary confinement for example). Though, knowing how the DeathNote rules go normally, the victim would probably just die of a heart attack.
The wikia contains a full list of all the rules regarding the use of a DeathNote.

Re your second paragraph: Yes there are. It's in that same rule. If the situation and cause are impossible, the Death Note defaults to a heart attack. Save heartless robots, a heart attack is never impossible.

@Jan I saw that the result of both the cause and the situation being impossible was a heart attack, but I didn't see anything in regards to if only the cause was impossible, such as if you wrote shot as the cause but they were surrounded by metal walls.

Its not possible to stop the person dying from the written cause.
The Death Note has no provision for avoiding death until and unless the writer doesn't have the person's face in their mind when writing his/her name.

Is there any significance in Mr. Tanaka's chibified form?
In Kuroshitsuji, most of the time Mr. Tanaka is drawn in chibified form and says nothing but "ho ho ho". At certain times, however, he reverts back to his normal form for a short amount of time, like when he returned to his former rank of head butler following Sebastian's absence. Is there any significance to this? Does it has any meaning for the story?
Edit: I mean like how Finny was a kaizo-ningen (he underwent an operation to gain inhuman strength) or how Mei Rin was an assassin and Bard was a soldier.

This is just my perception but for one comedy, and for two intensity. It's always funny to see "cute little Tanaka-san" sitting and drinking his tea and frankly, it always makes me smile. Maybe there is a reason as to why he is usually in chibi mode since they've said he has a time limit to being in normal mode. For the intensity part, if you've noticed, he only reverts to his normal state in serious or significant moments in the series, so when we see him that way we know that a) this is a really significant moment or b) it's about to go down.

In episode 1 or 2 there's a short explanation by Finn but I didn't quite remember it although it had something to do with hot or cold.

Who is Mizuki in SawanoHiroyuki[nZk]:mizuki?
I really liked the songs sung by "Mizuki" of SawanoHiroyuki[nZk]:mizuki in the Aldnoah Zero opening/ending/insert songs, so I tried looking for other songs that she sang.
However, I can't seem to find anything on her. The main issue is a one word name is very ambiguous, and so googling "Mizuki" or "Mizuki singer" brings up a lot of results for Nana Mizuki and other singers with Mizuki in their names.
If I google "Mizuki aldnoah zero", which disambiguates my query a bit, then the problem is that I just get all the songs she produced for Aldnoah Zero, which I am already well aware of.
So does the Mizuki in question go by the name "Mizuki", in which case, any tips for differentiating her from other singers with "Mizuki" in their names?
Or does she go by a full name that got omitted in SawanoHiroyuki[nZk]:mizuki or a completely different one?
Or is she just only producing music under the name SawanoHiroyuki[nZk]:mizuki? (I ask this because Aimer still has songs under her own name even though she collaborated with Hiroyuki Sawano as SawanoHiroyuki[nZk]:Aimer)

The mizuki in question is this mizuki. Her personal blogs (in Japanese) are ５６番線 on ameblo and note.mu/mizuaoi. Her Twitter handle is @mizukizuiaoi.

Or is she just only producing music under the name SawanoHiroyuki[nZk]:mizuki?

She seems to be the vocalist for the band "Itsue", where she is also known by the single name "mizuki" (but it's written in Japanese as 瑞葵 there). Their YouTube channel has a few of their songs, which have vocals by her. Their discography page has links to purchase more of their music, if you're interested.

Or does she go by a full name that got omitted in SawanoHiroyuki[nZk]:mizuki or a completely different one?

She doesn't seem to go by a full (two-part) name in any of her public appearances. This isn't terribly surprising; I get the impression that pseudonym among Japanese music artists is fairly common.

So does the Mizuki in question go by the name "Mizuki", in which case, any tips for differentiating her from other singers with "Mizuki" in their names?

Your best bets are probably to search for things like "nzk mizuki" (for her stuff co-produced with Sawano, which at present is just the Aldnoah.Zero stuff) or "itsue mizuki" (for her band work; in Japanese, "イツエ 瑞葵").

How far can you manipulate someone with a Death Note?
We know that if you kill a person via a disease, the Death Note isn't limited to the 23 day rule. Now those who have watched death note know, you can manipulate a person to an extent. So my question is, could I write something like this?

John Doe, Diabetes. Obeys every command from the person he knows as J, till he dies.

Could this work?

There are different ways to interpret this question.
So let's break this down

John Doe, Diabetes. Obeys every command from the person he knows as
  ''J'', till he dies.

SO according to rule 23

If you write die of disease like before with a specific disease's
  name, but without a specific time, if it takes more than 24 days for
  the human to die the 23 day rule will not take effect and the human
  will die at an adequate time depending on the disease.

So the first part of your question

John Doe, Diabetes.

works fine and the disease would take a natural course of action.
But here is the catch. You cannot let another person control the user as easily as you think. In the second sentence

Obeys every command from the person he knows as ''J'', till he dies.

You have entered the name 'J' and would kill the person named as 'J' using a heart attack.
Also the line states "Every command" that 'J' gives. SO "every" command could also include that 'J' orders john doe to do things he would not like to do or 'J' could order 'Jon doe' to kill others which is not possible. According to TV tropes

The first is that the Death Note can only kill one person per name. If
  it brings harm to anyone else, the person will just die of a heart
  attack. Also, aliases don't work, period. The Death Note doesn't know
  who L or Kira or Wedy or Aiber or Near or Mello or anyone else with an
  alias are. Real names only. However, you could write something like
  "Report Siht. Demolishes a hotel, then subsequently dies." and then
  write "L Lawliet. Crushed by falling debris as his hotel is
  demolished." As long as two names are written, they are able to
  interact.

So there is a limit of how much you can control and you cannot pass the control to someone else without killing them(since you wrote 'J' in death note already). So you statement in the death note would fail and would kill 'J' with a heart attack and also kill 'John doe' with a heart attack as the "Obeys 'every' command" is ambiguous.
EDIT: In respect to the comment by Dark Yagami.
What works:

John Doe, diabetes. Eats fries and gummy bears, cheats on his
  girlfriend

would work and you can control them as long as you want (at least till they die of diabetes).
What does not work:

John Doe, diabetes. J, diabetes. John Doe obeys every command of J

won't work. Because you transfer control of power to change the lives of other people (in this case J could ask John Doe to kill someone or make John Doe do something impossible like fly to California from Japan in 2 mins. You cannot give an ambiguous command or control of other people's lives in the Death Note as the death note would just kill John Doe with a heart attack and J with diabetes in the above case.
One thing you guys must understand is, Death Note does not transfer the ability to control the lives of anyone other than the ones in Death Note. So you cannot make someone do something they would never contemplate. So handing over life of someone to another person is impossible for death note to do.
Source: http://tvtropes.org/pmwiki/pmwiki.php/Headscratchers/DeathNoteRulesOfTheDeathNote
http://deathnote.wikia.com/wiki/Rules_of_the_Death_Note

Okay. Now if I would write; John Doe, Diabetes. Obeys every command from the person he knows as: Josh Fortez, who also dies on diabetes. Would that work?

As I said in my second point of failure. Obey every commmand is ambiguous. The command could be something that would ask john doe to kill or affect others lives. It should be specific and not giving a power of control to anyone. No one can control other person's lives completely. You can write , john doe cheats with his girlfriend,eats fries and gummy bears. But not say "XYZ" can control "john doe". It would violate the rule that "XYZ" can alter lifespan of others and kill john doe with a heart attack and let "XYZ" die of diabetes.

check the answer for the edit with new example.Hope that makes it clear.

Then what about; John Doe, diabetes, will never say, nor confess to anyone, that the person he knows as Josh Fortzes, who dies with diabetes, is Kira. ?

Yes, that should work thoeretically .Also if John doe is someone who has a high sense of justice like lawliet or some of the police force who wants to catch kira, this would not work as it would command them to go against their sense of justice as it is something they would not do naturally. (Btw are u some english teacher?,where do you find all these convoluted sentences to break the death note.rofl) Yeah the death note is not intentionally made to control people like Geass and with the rules, the author has made so many fool proof mechanisms to stop it being used a human control device.

No I'm not an english teacher. Why do you think that?

Let us continue this discussion in chat.

I was just kidding ! lol

Ok then. One last question before I'll sleep... Do I write weird sentences?

Haha . No they are proper sentences and valid questions as far as i can understand .

"J" will not die of heart attack. You have to write the complete name, aliases won't work. Soon after getting the Death Note, Light wrote that a prisoner would write "L doesn't trust the police" (or something like that), but that didn't kill L.

'J' is not an alias. we are talking as if J is a real name. just a filler like john Doe.

I have watched the series only once and I am sure it is clearly stated in the series that it is absolutely possible to control a person's actions and manipulate him to do anything at all as long as it is physically possible for that person to do so.
But I don't really think if that command is going t work. You see, death note only kills a person and you can make a person do some stuff before he eventually dies. There might be a time limit for manipulating the person before he dies but I am not sure about that. I think I read something about this kind of stuff in the rules that appear in the series.

But the person does die in this situation. It's possible to control them, and even more possible to kill them through a disease, and since there's no rule that forbids that, I think that this could work.

But there's another thing. For instance, he wrote Diabetes. The death note only makes the person do things that are physically possible. Otherwise, he dies of a heart attack.
Now what if the person is fit and doesn't consume a lot of sugar? Death note is only supposed to alter a person's state of mind and make him to stuff. But bringing about a biological change in a person sounds kind of impractical to me, save for the heart attack though. That's the default case scenario.

As long as you don't command them something which is impossible, I doubt, that they die from a heart attack.

Please edit your answer if it is a continuation from the other post.

tl;dr: This will not work and John will die of diabetes at an adequate time. In the off chance that John is so healthy that it would not make sense for him to die of diabetes, he will ironically die of a heart attack instead.

Before I start quoting the rules, let us go back to the beginning. In chapter 6, when Light just got his Death Note, he was as curious as you are right now and did similar experiments to the question you have been having. In one of the failed experiments he requested a prisoner to write down the words I know L distrusts the police. Light almost thought it would work, but he guessed that it would be impossible for him to make people have thoughts they would never have. In other words, even with the Death Note, Light could not do the impossible, whether it would be physically impossible (eg: travel to Paris in 30 minutes) or mentally impossible (eg: draw a picture of an unknown person or write down something you would not naturally think of).
So coming back to your question, where John has to obey every order J gives him. It would be impossible for John to be thinking about obeying every command J tells him. Therefore, similar to what happened to the prisoner, the situation of death would become void and only the cause of death would occur as written down.

Relevant rule: Also, after writing the cause of death, even if the situation of death is written within 6 minutes and 40 seconds in the human world, the situation will only occur to the victims whom it is possible. For those where the situation is not possible, only the cause of death will occur. HTU:LVI

This would make the situation of John's death impossible, but not the cause. Therefore John will still die of diabetes, with nothing more specified about his death. Unless he is medically unlikely of gaining diabetes, as mentioned earlier. In that case, he will die of a heart attack.

Relevant rule: In the occasion where the cause of death is possible but the situation is not, only the cause of death will take effect for that victim. If both the cause and the situation are impossible, that victim will die of heart attack. HTU:LV

Since you did not specify a time of death, the 23-day rule was bypassed and John will die at an adequate time needed for the disease to take effect.

Relevant rule: If you write die of disease like before with a specific disease's name, but without a specific time, if it takes more than 24 days for the human to die the 23 day rule will not take effect and the human will die at an adequate time depending on the disease. HTU:XXVIII

Then what about; John Doe, diabetes, will never say, nor confess to anyone, that the person he knows as Josh Fortzes, who dies with diabetes, is Kira. ?

@DarkYagami I'm not sure what you are asking. Are you asking whether John will keep quiet, or are you asking whether Josh will die as well, because his name is written in the DN too?

@DarkYagami I added the scene from the manga if that clears things up for you. Basically something will work if it strokes with the natural thought-process of the victim. If it contradicts this, it will just be ignored.

You can write that but the person would die in 10 seconds because you didn´t put the time when he dies. (I think it was 10 seconds)

Which came first, The Blitzball Sign for Victory or the Yevon Prayer?
In Final Fantasy X, just as Tidus and Wakka enter Besaid, Wakka pulls Tidus back and confirms if he knows the prayer. After showing it to him Tidus's inner monologue says:

Any Blitzball Player would know that Prayer, that Prayer was the Blitzball Sign for Victory

and we can confirm this at the beginning when Tidus promises a group of kids to teach them how to Blitz and they give him the prayer.
However, later we learn the Zanarkand Tidus came from was actually a dream world created by the Faith on Mt. Gagazet, it also seem that the Faith in the temples can also go to this world as we see the Bahamut Faith appear at the beginning and also in Tidus's flashbacks

 and also when the truth about Yu Yevon is revealed, visiting the other Faith has them confirm they too are dreaming the Dream Zanarkand

But I am wondering, was the Yevon Prayer created from the Blitzball Sign for Victory after Zanarkand was destroyed or is the Blitzball Sign for Victory just the Yevon Prayer that was added to Dream Zanarkand by Bevelle/Yevon centric Faith?

should this be a question for http://gaming.stackexchange.com ? I don't think there are any manga/anime series in the FFX universe

@ToshinouKyouko JRPGs are still on-topic so long as it's about the plot. while plot/lore based question are also on-topic on Arquade i see good ones get downvoted in my opinion for no reason because from what i read there are some people on Arquade who just don't like them, so any JRPG question of plot/lore i ask here while most other games on Sci Fi (because most are sci fi anyway). also there's Final Fantasy X: Eternal Calm which you could put on the same line as Advent Children: Final Fantasy VII and there are the Novella and Ultimania though i don't know if any was released for X

I did a bit of meta-digging & Videogames on their own are allowed if they are "anime-styled", not just JRPGs - http://meta.anime.stackexchange.com/a/418/1530 - I suppose FF fits under that category, and unless anyone else has an issue, I'm guess I'm relatively okay with it staying open :)

As @Kai has mentioned, it is ambiguous and you'll have to make your own judgement call. I've written down a good chunk of information that may convince you either way.
Disclaimer: I believe it is blitzball which came first, but I have tried to make this balanced
Timeline:

1000 Years Ago: Machina War, Destroyal of Old Zanarkand
End of Machina War: Creation of Dream Zanarkand, Sin
In-game Present Day: Tidus leaves his home, Dream Zanarkand

When the Machina war neared the end, it was clear that it was being dominated by Bevelle thanks to the help of their machina Vegnagun. Yu Yevon was on the side of Zanarkand (Anti-Machina) who were slowly being destroyed.
In order to preserve the city, Yu Yevon turned the remaining citizens of old Zanarkand into the Fayth. The Fayth then created Dream Zanarkand, based off of memories of their life in the old city. To protect this place of peace, Yu Yevon created Sin to defend Dream Zanarkand and rid the world of traces of machina. Yu Yevon may not have been a symbol of religion at this stage, but he had a large following. It would not be strange for a community of a united cause to have a symbol of respect and unity while he lived.
The dream Zanarkand is composed merely of the Fayths memories of the old city and their lives. It also resides in a space distinct from the rest of the world. These two facts combined give us evidence that the Fayth must have known of the symbol before Dream Zanarkand was constructed.
The point of Dream Zanarkand was to restore Old Zanarkand to it's pre-war state and to preserve it for eternity. Since Dream Zanarkand was pre-war - there would have been no large following of Yu Yevon as the powerful summoner defence against the machina. Even if this symbol was in use, it is much less likely that an already established sport would take on the idealisms and symbolisms of one man's following, than it is to believe that Yu Yevon adopted the symbols as they were already representative of victory and strength.
In the first moments of Final Fantasy X, we follow Tidus in Dream Zanarkand, many traditions have been forgotten as years have gone by. Souls no longer need to be sent, there is no evidence of the existance of aeons, and the Hymn of the Fayth no longer holds any meaning. This is the main point of contention - Does the fact that the Hymn exists mean that the Hymn originate from the fayths' subconsciousnesses as they reside in the world (Not related to Yevon)? or was the dream city created to represent the city whilst Yu Yevons still had its following (Originates from Yevon, Possibility the symbol does also)?
The Hymn of the Faith roughly translates to (after some puzzle solving seen in the link):

Pray to Yu Yevon
Dream, Fayth
Forever and ever
Grant us prosperity

The lyrics indicate the acknowledgement of the Fayth's creation by Yu Yevon and how they are to reside there forever and ever in a dreamlike peace. This makes the song even more important in assessing the timeline of the symbol.
The wikia and other sites claim that blitzball came first, but none cite any solid articles or go into more detail than passing mentions. Therefore, you must decide yourself which possiblity you believe is more plausible.

Specifically, the wikia claims here that the prayer "evolved from a blitzball ritual", though no source is given.

http://finalfantasy.wikia.com/wiki/Dream_Zanarkand
As far as I know, this is left somewhat ambiguous.  Dream Zanarkand is based upon the memories of people that lived there, yet it is clearly also different from the actual Zanarkand.
But we can also consider that Yu Yevon was supposed to be contemporary with the true Zanarkand.  He does not seem to be known in the idealized dream Zanarkand.  And yet the Fayth, who were also contemporary with true Zanarkand, must know of the sign, in order to have dreamed it.  But furthermore, at that time, Yu Yevon was not really a religious figure I don't think, though he may have been the object of a cult of personality.  Therefore, I think it's safe to guess that the Yevon Prayer did not begin as a prayer exactly.  Perhaps it was a sign for Blitzball victory, or I think more likely, some sort of general salute that people would have done in support of Yu Yevon, and perhaps also for victory in blitzball.

What is the difference between hot spring water and regular hot water?
In the last arc of KonoSuba season 2, Aqua winds up purifying the hot spring water, turning it into "regular hot water".
What is the difference between hot spring water and "regular hot water"?
The only clue I can see is that it's (hot spring water) animated green instead of clear or bluish clear (regular water).

Generally hot springs are considered to have water with purifying qualities since its from mountains and forests. And regular hot water is just... Normal hot water.

does Aqua "purifiy" Hot Spring Water into Normal Hot Water? because that sounds like the total opposite of what normally happens and how you describe the change of water does suggests the opposite (in some anime Hotsprings Water is green and normal water is blue/clear)

@Memor-X idk how you interpreted it 180 degrees from what I said, but I added some notes to make it clearer.

@YetAnotherRandomUser "turning it (hot spring water) into "regular hot water"." is how i did, as if it was hot spring water at first then was chnaged to regular water

You might be looking for something that's analogous to 温泉 (onsen) vs 銭湯 (sentō) in Japan.
By definition, onsen is hot spring water which (supposedly) contains minerals and other things that makes the bath more healthy and provide relaxation benefits (animated green in KonoSuba), while sentō is normal heated tap water (animated blue).
Aqua purifying the onsen water would have implied that she had taken out all the "impurities" (i.e. the beneficial minerals) in the water, and leaving it with the inferior "just hot water."
Regarding animation, it's not always consistent that onsen water is colored green.

How do the adventurers know the floor boss's names?
In Dan Machi on the side, Aiz faces off against a floor boss (Udaeus) all by herself (with 1 observer).  Yet, it seems apparent that everyone knows the monster's name.
How would the adventurers know the floor boss's names?  In this case, the particular floor boos doesn't make any verbal sound for some reason.  Presumably, other floor bosses will not speak but may make noises.

Because somebody has fought them before and those Bosses just respawn?

Based on Danmachi's lore, it is possible (i'd like to say almost sure but no proofs here) that monsters have something to do with gods. If it is the case, maybe gods were those who named the floor bosses.
There also are more possibilities. Those monsters, unlike Grimgar's, are more likely to respawn like basic RPG monters. If adventurers already fought a floor boss, it is legit it is has a name. Maybe those who are the first to defeat a kind of boss are given the great honor to name it.
Sadly, Danmachi's doesn't tell us much about it so it is only speculation. Maybe we'll learn more about it later in the story.
Hope that helped.

Does the Hellsing manga cover more material than either anime series?
Does the Hellsing manga cover more material than either anime series? I read the wikipedia page, but didn't see any mention of it.  For example, does the manga continue the story where the animes leave off?
I'm not a big manga fan, so I don't know how books and chapters translate to anime episodes in general, let alone to this one.
Watching Drifters makes me want more, so I started rewatching Hellsing Ultimate and I'm thinking about getting or reading their mangas.

I'm going to run with the assumption that you mean which goes more in depth with certain things. And even then I'd have to say neither really. I own the manga and have watched both anime and they all seem to have the same amount of focus and detail. The anime is just longer and more drawn out because it's an anime.
It was clarified that you probably meant about filler and such well the original anime is kinda faithful until episode 6 when it just leaves completely. However Hellsing Ultimate covers the manga perfectly and completely with no filler as far as I'm aware.

Usually, for question like this, OP wants to know what's considered as the source material, and whether the adaptation is following the source material faithfully (1-to-1 conversion), or have additional/filler story, or just fully diverge from the source (i.e. original story)

Yeah, I guess that was vague.  I added some clarity.
