After ignoring warnings from a mysterious student named Mia, Reina and Kumi perform a forbidden spirit summoning ritual that leads to a series of tragic events and supernatural possessions. As their friend Mari suffers a brutal fate and the girls are targeted by a malevolent entity, Mia uses her medium abilities to exorcise the spirits. In the aftermath, Kumi adopts a baby fox and is recruited into Mia's paranormal club.
When rumors of a rapist terrorizing the school surface, Mia discovers that the attacks are actually the work of a doppelganger spirit born from the repressed desires of a former student named Kitagawa. After learning that Kitagawa's suicide was triggered by a heartbreaking breakup with Miyu Shimizu, Mia orchestrates a reconciliation between the two. By fulfilling Kitagawa's long-dormant emotional and physical needs, they are able to banish the distorted spirit and bring peace to the school.
