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--
They were stabbed to death by a cursed spirit 
at the entrances to their apartments,
،طُعنوا حتى الموت من قِبَل روح ملعونة عند مداخل شققهم
Sie wurden am Eingang ihres Apartmentgebäudes
von einem Fluchgeist erstochen.
Fueron apuñalados por un espíritu
en la entrada de sus departamentos
Fueron apuñalados por un espíritu
en el portal de sus apartamentos
Ils ont été attaqués par un fléau
dans le hall de leur immeuble.
Trafitti a morte da uno spirito maledetto,
di fronte alla propria abitazione.
Morreram perfurados por um espírito
amaldiçoado na entrada de seus apartamentos
Заколоты проклятым духом
у входа в свою квартиру.
