About

Oni: They use abilities called Blood Release, which use blood as a medium. Most do not know how to control it and typically go berserk, posing a great threat to civilians. Therefore, they are being exterminated by the Momotaro Agency regardless of whether they have actually caused harm. When their abilities awaken, horn-like structures grow from their heads. Momotaro: An Oni extermination agency composed of descendants of Momotaro. They carry out missions to subjugate Oni or their descendants. The combatant descendants of Momotaro use abilities made of black 'bacteria' originating from their blood. To ordinary citizens, they are grateful beings who subjugate Oni before they go berserk, but fundamentally, they unconditionally massacre Oni even before any actual damage occurs. They use any means necessary to exterminate Oni, under the pretext of eliminating Oni descendants for the sake of humanity. Protecting humanity from the threat of Oni is just an excuse; in reality, they are closer to a group of hypocrites committing genocide simply because Oni and humans are different.
