Seventeen-year-old Aiko lives a life of casual sex and casual violence, though at heart she remains a schoolgirl with an unrequited crush on her old classmate Yoji Kaneko. Life is about to get harder for Aiko, as a recent fling, Sano, has been kidnapped, and the serial killer Guru-Guri Majin (Round-and-Round Devil) has begun slaughtering children. The youth are rioting in the streets, egged on by the underground Internet bulletin board known as Ten-no Koe, the Voice from Heaven. Expecting that Yoji will come and save her from the madness, Aiko posts a demand for her own murder on Ten-no-Koe, but will she be left waiting...or worse?
