First appearance: Battle 167 Age: 29-30 Type: Sei Type: Satsujin Ken Yami Symbol: Sky Martial Art: Karate (specializes in Shinchi Nengen style) Hongou Akira is a member of Yami's One Shadow Nine Fists, he is a master that utilizes Karate, he was the master of Kanou Shou (who died after being defeated by Kenichi during the D of D tournament). He scorns on using science and technology as tools to measure one's level of martial arts, but does not hesitate to raise the obstacles and difficulty level for Shou when he was in an experiment. Evidence showed that though he was extremely hard on Shou, it was because he wanted to dispel the doubts of several other people including the One Shadow that Shou had the right to be the 'Sole Successor'. Thus, he was a stern and cold teacher to Shou so that the disciple would never lose a match, which might discredit his and Shou's reputation. However he let Shou do as he pleased sometimes, including keeping a little bird and riding on him for a while on boat. Hongou is a rather serious man when it comes to many things, even as simple as meeting the other Fists. Even when taking simple kind gestures from others such as Lona thanking him, he did not talk and just stared sternly. He's also a very quiet person, as he rarely speaks unless he wishes to, especially in battle. He scorns the use of science and technology to measure one's level of Martial Arts, though he has shown he doesn't mind using it to train Shou. Despite his cold nature, he has a rather close bond to his disciple and cares for him deeply, as their relationship is like that of a father-son like relationship. He has faith in Shou that he is the 'Sole Successor' and wishes to disapprove everyone's opinion of Shou that he is not worthy of the title. He has also shown visible rage when he heard Shou died during the D of D Tournament and even mourned the loss over his beloved disciple. He harbors a great hatred for Ryozanpaku, as it is revealed that he received his scar from Sakaki Shio and is clearly upset when he learns Shou died saving Fuurinji Miu. In the battle for the Karate successor of Yami, he tells Kenichi to tell Sakaki that they will "end this soon." When he was still friends with Sakaki, Hongou was seemingly more soft-hearted and spoke more than he does now. He also seemed to have been down the path of the Katsujin Ken since he helped saved several people from getting killed on more than one occasion such as how he leaped in front of some bullets just so the hostages wouldn't get hurt. Hongou's reason for embracing the Satsujin Ken is out of honor for Suzuki Hajime, who demanded a death match with him when Yami pitted Sakaki, Hajime, and him in a death match for the succession of Karate in Yami. His conflict with Sakaki stems from this reason: whereas Sakaki wanted to let Hajime live and do what was best for him, Hongou was more concerned with fulfilling Hajime's wishes, calling Sakaki "selfish" for refusing to understand that. While he shows to be ruthless and very serious most the time, he, compared to the other members of Yami, has proven to be very honorable. He stopped his fight with Sakaki and assisted him in trying to save Miu from Jenazad when Jenazad interfered and even promised the Elder that he would return her to her home. Even Sakaki vouches that he is a man who keeps his word. He also has a high respect for the Kuremisago clan, stating that he couldn't bring himself to shed blood on their sacred land. He also wishes for no disciples to lose their lives in battle, such as stating to Sakaki that he wishes for Kenichi and Miu not to die in their fights with Jenazad's men, showing a more compassionate side.
First appearance: Chapter 176 Age: 19 Type: Dou Type: Satsujin Ken Yomi Symbol: Void Martial Arts: Kalarippayattu Ethan Stanley is Pollux of Yomi, younger twin brother of Rachel, and the disciple of Sehrul Rahman. He is an incredibly tall and immensely muscular young man for his age with short light blond colored hair. He wears a tight t-shirt with dark pants and, in an effort to fit in at Kenichi's school, he was seen wearing a school uniform. When fighting, he is usually bare chested and wears a Kalaripayattu loincloth to increase his mobility. Ethan mostly keeps a stoic expression and follows his older sister around. He demonstrates a great amount of resilience, able to get along with his sister despite being constantly ordered around and attacked by her, and expresses great concern for her well being, going as far as to punch a client who said that he wanted to "buy her" from Yami. Even though his sister rarely shows any form of care for her brother and her frequent mistreatment towards Ethan, he has shown that he loves his sister very much and is willing to do anything for her and even was saddened how he lost his fight with Kenichi, thinking she would end up dying because of his loss. Like his master, he is a very considerate person who shows little, if any, offense towards anyone, including his enemies. He doesn't seem to be irritated by others doing things that annoy him, such as when some girls were playing with him and tying up his short hair for fun, he didn't seem to be bothered by it, suggesting he doesn't let minor things bother him. Ethan is described by Kenichi as the most honest person in Yomi, out of the rest of the Yomi transfer students, he didn't do anything bad in school, defended his classmates on the camping trip, and tries to think of peaceful solutions to solve problems, such as having Kenichi die as a martial artist once again as the best solution for both of them. Further reflecting his contrast with his sister and his honesty, Ethan uses rather conservationist attacks while his sister uses all manners of flashy moves. When he fights, he seems to switch from a quiet giant to a raging berserker. He mostly goes all out when fighting, though he will use different stances and hit pressure points to weaken the enemy if the enemy proves resilient. Though he is on the side of the Satsujin Ken, he appears to be more suited for the Katsujin Ken. He does not attack Kenichi despite given obvious chances, takes on missions of body guarding, and is taking on even more missions to save his sister. It is revealed that his master took him on trips to India, where he made a lot of friends. He claims that his friendship with them was all an act, and only said goodbyes to them as a part of the act.

A perverted high school student. He hates his father believing him to be the reason his mother died. He wields a power known as "blood pointer" which allows him to drain "element" from the people around him through his mouth. He has periodically used this ability throughout the series without knowing it. After the battle with the Venus unit he has begun to undergo training to understand this power and use it. He is the childhood friend of Haruko Ayama. His maken is known as "Overblow", which lets him cause his opponent's maken to gain incredible power and overflow with element causing it to go out of control and force the user to not be able to use it. However, when his opponent is able to contain the overflow of element or has perfect control over his maken, it would only provide his opponent greater power or even make the maken evolve into something greater.
