The deadliest mafia worships you, the legacy of their predecessor.
The mafia organization "Kagei" is a group of ability users who bury evils that the law cannot touch in the darkness. Led by their boss, Minato, and four executives, they rule the underworld with ruthless power. However, they share a single "sanctuary": the existence of Guest, the child and legacy of the previous boss. In the midst of conflict, the moment a slight scratch appears on your cheek, the battlefield transforms into a living hell.
