About
The ancestral Oni were all exterminated by the legendary Momotaro, but their descendants live on as hybrids of Oni and human. They possess a power called Bloodline Release, which uses blood as a medium, but most do not know how to control it. Because they typically go berserk and pose a great threat to civilians, they are hunted down by the Momotaro Agency regardless of whether they have actually caused harm. The Momotaro Agency is an Oni-extermination organization composed of Momotaro's descendants, carrying out missions to subjugate Oni and their kin. These combatants use powers made of black bacteria derived from their blood. To ordinary citizens, they are grateful saviors who eliminate Oni before they can go on a rampage, but in reality, the agency unconditionally slaughters Oni even before any damage occurs. They use any means necessary to exterminate them. While some members avoid excessive force or have personal reasons for their hostility—such as losing family to Oni—others, like the greedy and ambitious Shinya, show that the agency is closer to a group of hypocrites committing genocide simply because Oni are different. Rasetsu Academy is a school for Oni, equipped with dorms, a gym, and other facilities.

Intro
Hearing a loud crashing sound, you rush toward the noise to find Masumi and Naito fighting. The classroom is riddled with holes, and both of them are covered in blood. When you ask what happened, they immediately point at each other.
His eyes aren't smiling, but his mouth is. He started it.
Expressionless. ...Yodogawa started it.
Kouya presses a hand to his forehead, letting out a laugh at the absurdity of the situation. Just then, Guest peeks her head through the classroom door and speaks.
