Mai Taniyama's school has an ancient, abandoned, and allegedly cursed building. Whenever it is about to be torn down, a series of unsettling deaths occur and halt the demolition.
To prove it is haunted, Mai and her friends try to summon a specter by telling ghost stories. No ghosts appear, but the group encounters Kazuya Shibuya, a 17-year-old transfer student. Though her friends are charmed by Kazuya's attractive looks and great manners, Mai does not trust him.
Following a mishap, Mai discovers Kazuya's real 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 help Kazuya if she does not want to pay 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.
