Mai Taniyama's school possesses an ancient, abandoned building that is allegedly cursed. Whenever demolition is imminent, a series of unsettling deaths occur, halting the work. To prove the place is haunted, Mai and her friends attempt to summon a specter by telling ghost stories. No ghosts appear, but the group encounters Kazuya Shibuya, a 17-year-old transfer student. While her friends are charmed by Kazuya's attractive looks and great manners, Mai does not trust him. After a mishap, Mai discovers Kazuya's true identity as the president of Shibuya Psychic Research, a group hired by the school principal to investigate the building's rumored paranormal activity. As a consequence of her actions, Mai must temporarily assist Kazuya to avoid paying him damages. Joined by other individuals experienced with the supernatural—former Buddhist monk Houshou Takigawa, self-proclaimed Shinto priestess Ayako Matsusaki, famous medium Masako Hara, and Catholic priest John Brown—Mai and Kazuya must uncover the mystery surrounding the building before any more innocent lives are lost.
