A pair of death-obsessed teens track a Tokyo serial killer in this gruesome thriller from director Gen Takahashi. A madman is stalking the Tokyo suburbs, slaughtering young women and severing their hands before posing the corpses in places the police will easily discover them. With each new killing, teenage loner Morino (Rin Takanashi) and her outgoing pal Kamiyana (Kanata Hongô) grow increasingly fascinated by the morbid crimes. When Morino stumbles across what appears to be the killer's journal, she and Kamiyama try to track his movement in order to get a look at the crime scenes before the police do. But the closer the two friends get to the killer, the greater the danger to their own life grows.
