FILE 6: Forbidden Pastime #2

Mai has a dream about the school where dozens of spirits, including will-o'-the-wisps, are devouring each other. Mai and Masako later see Sakauchi's ghost being similarly absorbed. They discover that "orikirisama", a type of Ouija boarding, had become popular among the students, and that Sakauchi may have been one of the propagators of the trend, resulting in the many spirits inhabiting the school. While retrieving a video tape, Mai finds herself locked in a room with bottles crashing down around her, releasing the smell of formalin.
