Synopsis
Ren Fujii, an ordinary high school student, recently got into a physical altercation with his former best friend, which caused their friendship to end. With support from his childhood friend Kasumi Ayase and his senior Rea Himuro, he slowly starts to get back into the swing of his everyday school routine. However, a wave of gruesome murders where victims are found decapitated begins occurring across their town. Around the same time, Ren experiences unsettling nightmares where he himself is beheaded by a guillotine. These horrors, though, are merely a preview of the brutal and terrifying conflicts that lie ahead.
