Characters
Rasetsu Academy
Students
Shiki is an oni whose powers manifest after an attack by the Momotarou results in the death of his adoptive father. Biologically, he is one of the eight children of Kishin and inherits the Fire elemental attribute. His Blood Eclipse Release manifests as various guns, a reflection of his past interest in them. The tremendous output of his power generates severe aftereffects, such as causing blood to rain from the sky.
A student in Shiki's class and his roommate. His father is a Momotarou who previously attempted to kill Jin after he discovered his son was an oni, leaving Jin with scars and stitches all over his body. His father also killed his mother and sister for the same reason. As a result, Jin seeks little else but to eventually get powerful enough to kill his father, often brushing off Shiki and the others. His Blood Eclipse Release manifests as buzzsaws that pop out from his wounds.
A student in Shiki's class, as well as his love interest. In her past, she was heavily abused by her parents, leaving her constantly apologetic and self-deprecating. Her Blood Eclipse Release manifests as the "Blood Titan", a gargantuan, ghoul-like representation of her sister, who used to protect her from their parents before being killed by their father.
A student in Shiki's class. Having a volatile temper, his Blood Eclipse Release manifests as any object that comes to mind whenever he is in a bad mood.
A student in Shiki's class. Though he generally appears collected and intelligent, he is actually a massive pervert who frequently tries to lose his virginity, to no avail. His Blood Eclipse Release manifests as sonar, which activates by seeping into cracks and traveling relatively far distances.
A student in Shiki's class. He is extremely averse to all uncomfortable situations, a result of him losing his oni girlfriend to an illness. His Blood Eclipse Release manifests as paper fans and a dancing outfit, having been a dancer in the oni village he grew up in.
A student in Shiki's class. Though usually appearing brash and tough, she has a motherly fetish that causes her to uncontrollably dote on people she sees as weak and is attracted to. Sazanami soon forces Kiriyama into a relationship under this pretense, much to his dismay. Her Blood Eclipse Release manifests as kickboxing gloves.
Staff
The mysterious headmaster of Rasetsu Academy. Though he and Mudano have a good relationship, he rarely speaks to him in person and is almost always covered from head to toe in traditional Japanese garb; his real appearance is that of an androgynous man with blue skin, white hair, and tattoos all over his body.
The teacher of Shiki's class. A taciturn, strict man, he is a highly-skilled fighter respected as such by both the oni and the Momotarou. He often travels on roller skates instead of walking. His Blood Eclipse Release manifests as an umbrella.
A medical oni initially the main force behind the medical wing of the oni's Kyoto branch, but later becoming Rasetsu Academy's personal doctor. His Blood Eclipse Release grants him the ability to perform miraculous blood transfusions that can even restore lost limbs, although he can only do a certain amount at a time. Though often called out for being lecherous, he has a deep care for his patients.
Oni
An oni in the reconnaissance unit who is disguised as an ordinary librarian. He activates his Blood Eclipse Release by shaking a vial of his blood. The blood echoes back, giving him the locations of nearby people and the layouts of buildings, much like animal echolocation. Additionally, anyone can use his power by shaking the same vial, though there are certain restrictions; one such restriction is based on a person's IQ.
The captain of the Nerima branch reconnaissance sector. He always has an unsettling smile, regardless of how tense a situation is. His Blood Eclipse Release grants him the power to go invisible for about 10 minutes. This also includes his clothing. It is activated by simply consuming his own blood.
Momotarou
The main antagonists of the series, based on the Japanese folk heroes of the same name. Similar to the oni ability to manipulate blood, Momotarou are able to wield their own black bacteria for this purpose.
A leading Momotarou officer with an intense hatred for oni. Driven by envy for his colleague Tsuyoshi Ichinose, he murdered him after hunting him down when he left the Momotarou agency.
A captain in Kyoto's Momotarou branch. A sadistic man, he lost his capacity for empathy after a berserk oni child murdered his mentor and the latter's family, and came to work primarily in a scientific capacity, dissecting oni corpses. His Momotarou ability allows him to manipulate corpses, including homunculi creations of his own making, that he transfers his bacteria to. After leading the assault on the oni's Kyoto branch, he is mortally wounded by Shiki's awakened Enki abilities, before being finished off by Mudano.
Tsubakiri's partner. Her Momotarou ability allows her to create near-impenetrable walls with her bacteria.
A captain in Tokyo's Momotarou branch. His Momotarou ability allows him to peer into the vision of up to 36 people for 24 hours. He is also capable of making a target see his vision, as long as his bacteria is present on them. Due to the non-combative nature of his power, Momoiwa was often deemed by fellow Momotarou as being unable to advance highly, causing him to become obsessed with status and begin using underhanded tacticsâÂÂincluding breaking Momotarou policy by putting the lives of humans in dangerâÂÂto advance through the ranks. He targets Shiki with the hopes that killing Enki will further advance his rank, and resorts to manipulating Mikado and torturing Kougasaki to do so. Momoiwa is eventually killed after Kougasaki uses his oni power to slit his throat.
A kindly Momotarou and Momoiwa's partner, regarded as a prodigy. He and Shiki, unaware of each other's identities, became fast friends after meeting each other in Tokyo. Momoiwa used this to reveal Shiki's true identity and manipulate him into thinking that Shiki murdered innocent humans. After they part ways, however, Mikado expresses sympathy for the oni, which causes him to get transferred. His Momotarou power is similar to Shiki's oni power in that it allows him to create guns.
An officer in Tokyo's Momotarou branch, and Osuke's partner. His Momotarou power allows him to use his bacteria to create soldiers based on tarot cards that he draws. Because of his ability, he has an extreme proclivity towards fortune telling, and often will not indulge in combat if he draws an unfavorable fortune. He is defeated by Mudano, but has his life spared.
An officer in Tokyo's Momotarou branch, and Tsukuyomi's partner. A bloodthirsty man, he solely seeks the thrill of the fight and challenges oni such as Mudano with the hopes of defeating powerful opponents. His Momotarou power allows him to use his bacteria to copy the ability of any ability he sees within a 24-hour period. He is eventually defeated by Ikari, but survives after being recovered by other Momotarou.
Other characters
Shiki's adoptive father. Formerly a Momotarou partnered with Momoya, he took an infant Shiki in after discovering that he is a child of Kishin and left the organization, presumably due to being unable to murder a child. Momoya's envy eventually drove him to murder Tsuyoshi.
