Three men have died under similar circumstances from a cursed spirit. Investigators discover the victims all attended the same middle school, so Itadori, Fushiguro, and Kugisaki are dispatched to investigate. Once they arrive, they learn it was Fushiguro's old middle school. There they learn that the victims were all found unconscious beneath Yasohachi Bridge, a local haunted location. They also learn that Fushiguro's older sister, Tsumiki, is caught up in this incident as well--
Tsukimi-kun took awfully good care 
of you when you were in school.

na época da escola, né?
Она так хорошо заботилась
о тебе, пока ты здесь учился...
