The Shibuya Massacre in Jujutsu Kaisen began on October 00, 0000, with a terrorist attack in which Kenjaku demanded Satoru Gojo's arrival by lowering a massive curtain that imprisoned civilians. In the ensuing chaos at the subway station, where civilians were used as human shields, Kenjaku sealed Gojo in the Prison Realm, turning the entire area into a war zone. The mages, entangled in the chaos caused by Gojo's sealing in the Shibuya incident, perished in ambushes and battles, including Nanami and Naobito.
