Set in the Uchihama area during the early 21st century, Uchihama Academy is preparing for its final General Club Festival in the old school building, which is scheduled for demolition. The students are determined to make this last festival a memorable event. Sou Akiyama, a member of the Astronomy Club, is asked by the student executive committee to investigate a series of mysterious incidents, including ghost sightings, accidents, and a sleeping sickness, that have been unsettling the student body. The arrival of Yui Furukawa, a quiet transfer student, seems to coincide with these unfolding events.
