"quite a bit," and he wanted to give Raijūta "peace" in future stories, but added "then again...this guy—! Sigh." Raijūta's appearance was originally based on an American superhero comic book character, but as the story progressed, his appearance and personality "deteriorated." Because he had difficulty with "the complicated details" in the Oniwabanshū story arc, Watsuki gave Raijūta a relatively simple outfit with only one design flourish, the black feathers, which turned out to be difficult to draw. Watsuki concluded that the development of Raijūta taught him a lot about character design. Akamatsu Arundo is a mercenary of Shibumi, a corrupt politician. Because Arundo is jealous that Shibumi orders Saitō Hajime to kill Kenshin, Saitō allows Arundo to have the job, knowing he stands no chance. Arundo ambushes Kenshin and tries to use a chain to immobilize Kenshin but is ultimately defeated. Arundo discovers that Saitō is allied with Ōkubo Toshimichi. When Arundo, fearing for his safety, decides to cut ties with Shibumi and flee to Shanghai, Saitō appears and decapitates Arundo with a strike from his sword. Watsuki stated, "this character's only there to get beat up." Appearing to aid story development, Arundo does not have much personality aside from arrogance (Watsuki's favorite personality trait for villains). Watsuki believes that he could not make Arundo's chain-scythe appear like real chains. The character's design originates from a superhuman soldier in an American comic book who has a name similar to Arundo's, that being X-Mens Omega Red (aka meaning "red", and matsu corresponding to "end", equivalent to "Omega", which is the last letter of the Greek alphabet - also related to the Christian concept of Alpha and Omega). Arundo's use of chains also parallels Omega Red's carbonadium tentacles. Senkaku is a minion of Shishio Makoto who oppresses Shingetsu village, which after two years has been abandoned by the government. Senkaku killed Mishima Eiji's brother and parents after learning that the boys were plotting to escape the village. He claims to have killed 99 people. Senkaku fights with a pair of knuckle blades and has high speed, contrary to his size. However, this proves to be his undoing, as Kenshin defeats Senkaku in a battle by using the gigantic size to stress out Senkaku's limits, causing his leg to break. The police take Senkaku away, in which Saitō notes he would most likely be executed. In the anime, he manages to escape and
