At school, Taniyama Mai and her friends enjoy exchanging ghost stories. Rumors say that an abandoned school building on their campus is the center of many such tales. While telling these stories, they are interrupted by a mysterious man. He turns out to be Shibuya Kazuya, 17, president of the Shibuya Psychic Research Company. The principal had called him to investigate the legends surrounding the abandoned building. The next day, on her way to school, Mai passes the building in question. While examining a strange camera she spots inside, she is surprised by Kazuya’s assistant. Unknowingly interfering with the investigation, Mai breaks the camera and Kazuya.
