During an off-campus trip, the bus that the good girl Mitsuko (played by Trindl Reina) was riding in was suddenly cut in half by a gust of wind. Mitsuko happened to bend over to pick up something so she survived, but Ak and her companions all had their upper bodies cut off. The panicked girl ran away and witnessed the tragic scene of countless people being killed by the mysterious wind along the way. Suddenly, she seemed to be in the time before the disaster. The frightened Mitsuko went to school with Ak and her companions, but a massacre of high school girls followed. During the escape, Mitsuko seemed to travel through different time and space. She was the bride-to-be Keiko (played by Mariko Shinoda) and Izumi (played by Erina Mano) who participated in the marathon. The only thing that remains unchanged is that the pursuit of girls has never stopped... This film is adapted from the novel of the same name by Yusuke Yamada.
