is a Japanese novel series written by Baku Yumemakura. An anime film adaptation directed by Mamoru Oshii is in production.
KÃ Â Ã Âtori, an otherwise ordinary high school student, is plagued by a recurring nightmare in which a beast devours him from within. This unsettling dream reflects a latent power he does not yet understand. KÃ Â's life changes when he encounters Reiichi Kuki, an elite upperclassman who dominates the school through his intellect and presence. Their meeting triggers the awakening of KÃ Â's hidden abilities and draws him into a violent and surreal struggle involving inhuman strength, predatory instincts, and questions about what it means to be human. As the story progresses, KÃ Â is forced to confront the monstrous force inside himself and the role Kuki plays in shaping his fate.
Baku Yumemakura originally published the series as 16 volumes between 1982 and 2002, with cover illustrations by Yoshitaka Amano. It was later rereleased as 8 volumes between 2000 and 2002, again with covers by Yoshitaka Amano. Both the and editions were published by Asahi Sonorama.
