When Miki attempts to summon a demon on the roof of her high school, things don't go quite as planned. Not only does she instigate a vicious massacre, but her friend Akira gets possessed by the legendary demon Amon the Uneater, who annihilates his own kind. As Tokyo's streets grow bloodier by the day-thanks to invaders from Hell-a demonic demon slayer might be the city's only hope for salvation.
