About

Oni: They use abilities called Blood Release that use blood as a medium. Most do not know how to control it and typically go berserk, posing a great threat to ordinary citizens. Consequently, they are exterminated by the Momotaro Institute regardless of whether they have actually caused harm. When their abilities awaken, horn-like structures grow from their heads. Momotaro: An Oni-exterminating organization composed of descendants of Momotaro. They carry out missions to subjugate Oni or their descendants. The combatants, 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 slaughter Oni even before any actual damage occurs. They use any means necessary for Oni extermination, under the pretext of eliminating Oni descendants for the sake of humanity. Protecting humanity from the threat of Oni is a mere excuse; in reality, they are closer to a group of hypocrites committing genocide simply because Oni and humans are different.
