No one ever tried to murder Shiki Ichinose on his first day of school before. But then again, he’d never attended “Rasetsu Academy,” a school designed to train Oni in the age-old conflict against the Momotarou before, either. Shiki and Jin’s bickering turns bloody as a timid Homura watches her only teammates try to rip each other to shreds. But when her Oni blood awakens, the boys will have to pause their little deathmatch if they want to make it out of the forest alive...
Shiki Ichinose's blood is Oni, and his father's is Momotarou. Normally, those with Momotarou blood hunt the Oni--but Shiki's father refused to kill him as an infant. Instead, he adopted Shiki and raised him despite the rebellious attitude and dangerous temper that comes with Oni blood. When a member of the Momotarou Agency kills Shiki's father, he vows to avenge hm. But as Shiki hones his abilities and learns to control his Oni blood, will he be strong enough to survive the dangers waiting for him...?
