Tougen Anki characters

Tougen Anki is an action series built on a twist of the old Momotaro folk tale: the descendants of the Oni live hidden among ordinary people, while the descendants of Momotaro hunt them through an organisation called the Momotarou Agency. Shiki Ichinose, a hot-headed teenager, learns he carries Oni blood when the Agency comes for him, and he ends up at Rasetsu Academy, a hidden school that trains young Oni to fight. Each Oni draws power from their own blood, so every fighter has a distinct ability. The cast falls into three groups: Shiki's classmates and teachers at Rasetsu, adults from the Oni organisation's local units, and the Momotarou officers on the other side. This page covers 16 characters as they appear early on, without spoilers.

Protagonist

Shiki Ichinose 一ノ瀬四季

Rasetsu Academy · Japanese voice: Kazuki Ura

Shiki Ichinose is the protagonist, a rebellious, impulsive teenager raised by his adoptive father. He has no idea he is a descendant of the Oni until a Momotarou attack turns his life upside down and his blood awakens. At Rasetsu Academy he learns to use Blood Eclipse Release, which lets him turn his blood into guns. He is reckless, stubborn and loyal, and he wants to become strong enough to fight back.

Main characters

Homare Byobugaura 屏風ヶ浦帆稀

Rasetsu Academy · Japanese voice: Manaka Iwami

Homare Byobugaura is a student in Shiki's class at Rasetsu Academy. Hard experiences in her past have left her constantly apologising and quick to put herself down. Her power is anything but small, though: her Blood Eclipse Release takes the form of the Blood Titan, an enormous figure modelled on her older sister, who once protected her. The gap between her timid manner and the size of her power defines her.

Ikari Yaoroshi 矢颪碇

Rasetsu Academy · Japanese voice: Shogo Sakata

Ikari Yaoroshi is a hot-tempered classmate who clashes easily with others. His ability creates random objects from his blood that are tied to his bad moods, and he can only use it a limited number of times per day. He rejects Mudano's insistence that comrades matter, and that conflict becomes the starting point of the second season's story.

Juji Yusurube 遊摺部従児

Rasetsu Academy · Japanese voice: Natsuki Hanae

Juji Yusurube is a student in Shiki's class at Rasetsu Academy. He usually comes across as collected and intelligent, although there is a sillier side to him that shows up in the lighter moments. His Blood Eclipse Release works like sonar: his blood seeps into cracks in the ground and walls and travels a long way, letting him locate people and read an area. That makes him valuable for scouting during missions.

Rokuro Kiriyama 手術岾ロクロ

Rasetsu Academy · Japanese voice: Kaito Miura

Rokuro Kiriyama is a student in Shiki's class who will go to great lengths to avoid any uncomfortable situation. In a fight, his Blood Eclipse Release produces paper fans and a dancing outfit, a link to his past as a dancer in the Oni village where he grew up. Once he is dressed for battle, he shows a more outgoing and confident side that surprises anyone who knows only his cautious everyday self.

Kuina Sazanami 漣水鶏

Rasetsu Academy · Japanese voice: Aimi

Kuina Sazanami is a student in Shiki's class at Rasetsu Academy. She usually comes across as brash and tough, and she is not one to back away from a fight. Her Blood Eclipse Release takes the form of kickboxing gloves, so she fights up close with fast, heavy strikes. Behind the tough front, she has a soft spot for classmates she feels need looking after, Rokuro Kiriyama in particular.

Rivals

Jin Kougasaki 皇后崎迅

Rasetsu Academy · Japanese voice: Koutaro Nishiyama

Jin Kougasaki is one of Shiki's classmates and, at first, his sharpest rival. He is aloof, serious and focused on his own goals, and he does not hide his irritation with Shiki's loud attitude. His blood ability produces saw blades and chainsaws from his wounds, which makes him one of the strongest fighters in the class. The friction between him and Shiki drives many early scenes.

Mentors

Naito Mudano 無陀野無人

Rasetsu Academy · Japanese voice: Hiroshi Kamiya

Naito Mudano is the teacher in charge of Shiki's class at Rasetsu Academy. He is cold, strict and economical with words, and he puts his students through harsh tests from the very first day. In battle he carries an umbrella that lets him control a rain of blood. Behind the severe manner, he cares a great deal about teaching his students to survive and to value their comrades.

Supporting characters

Kyoya Oiranzaka 花魁坂京夜

Rasetsu Academy · Japanese voice: Ryōhei Kimura

Kyoya Oiranzaka is an Oni doctor. He first leads the medical wing of the Oni organisation's Kyoto branch, which is where Shiki meets him during the Kyoto arc, and he later becomes Rasetsu Academy's own doctor. His Blood Eclipse Release lets him perform remarkable blood transfusions that can even restore lost limbs, although he can only treat a limited amount at a time. That makes him essential after every battle.

Masumi Yodogawa 淀川真澄

Oni organisation · Japanese voice: Atsushi Tamaru

Masumi Yodogawa is the captain of the Oni organisation's reconnaissance unit in Nerima, Tokyo. He always wears an unsettling smile, no matter how tense the situation, which makes him hard to read. By consuming his own blood he can turn invisible for about ten minutes, clothes included, an ability that suits the information gathering his unit does. He becomes an important figure when the students arrive in Nerima.

Kaoru Namikido 並木度馨

Oni organisation · Japanese voice: Haruki Ishiya

Kaoru Namikido is an Oni in the Nerima reconnaissance unit who hides in plain sight by working as an ordinary librarian. His Blood Eclipse Release is activated by shaking a vial of his blood: the blood echoes back and tells him where nearby people are and how buildings are laid out, much like echolocation. Others can use the power too by shaking the vial, which makes him a useful partner in the field.

Tsuyoshi Ichinose 一ノ瀬剛志

Japanese voice: Tsuyoshi Koyama

Tsuyoshi Ichinose is Shiki's adoptive father. He raised Shiki alone and treats him with rough, good-humoured affection, even when the boy gets into trouble. He was once a Momotarou himself and left the Agency to bring Shiki up. His past is connected to the moment Shiki's ordinary life ends, and his influence shapes what Shiki chooses to fight for.

Antagonists

Tsubakiri Momomiya 桃宮唾切

Momotarou Agency · Japanese voice: Daisuke Kishio

Tsubakiri Momomiya is the captain of the Momotarou Agency's Kyoto branch and one of the first major enemies the students face. He is a cruel man who has lost his capacity for empathy, and he mainly works in a scientific role, studying the bodies of Oni. His Momotarou ability lets him control bodies that he has passed his bacteria into. His assault on the Oni in Kyoto opens the series' first large conflict.

Samidare Momoya 桃屋五月雨

Momotarou Agency · Japanese voice: Yasunori Masutani

Samidare Momoya is a leading officer of the Momotarou Agency and one of the first enemies to appear in the story. He holds an intense hatred for the Oni, and his attack in the opening episode is what tears Shiki away from his ordinary life. His shared past with Tsuyoshi Ichinose, a former colleague in the Agency, makes him a personal enemy for Shiki rather than just another hunter.

Shinya Momoiwa 桃巌深夜

Momotarou Agency · Japanese voice: Chiharu Sawashiro

Shinya Momoiwa is a captain in the Momotarou Agency's Tokyo branch and a central enemy in the Nerima arc. His ability lets him look through the eyes of up to 36 people for 24 hours, and he can also make a target see what he sees, as long as his bacteria is on them. Because the power is not built for direct combat, other Momotarou often underestimated him.

Mikado Momodera 桃寺神門

Momotarou Agency · Japanese voice: Shun'ichi Toki

Mikado Momodera is a Momotarou who works as Shinya Momoiwa's partner and is regarded as a prodigy within the Agency. He is kind by nature, which sets him apart from many of his colleagues. In Tokyo he and Shiki meet without knowing who the other really is, and they quickly become friends. That chance friendship across the two sides becomes one of the most important threads of the Nerima arc.
