During the Shibuya Incident in Jujutsu Kaisen, Satoru Gojo performed a series of legendary but tragic feats. Initially, he entered the B5F of the Fukutoshin Line to confront the disaster curses Hanami, Jogo, and Choso. To minimize non-sorcerer casualties while being surrounded by thousands of humans used as shields by the curses, Gojo utilized a 0.2-second Domain Expansion (Infinite Void). This brief activation stunned everyone in the vicinity for about two months in their minds but allowed Gojo to act in a split second. In that tiny window, he physically obliterated approximately 1,000 transfigured humans created by Mahito. However, the mental and physical toll of this precise maneuver, combined with the psychological shock of seeing a "living" Suguru Geto (who was actually Kenjaku inhabiting Geto's body), left him vulnerable for just a moment. This moment was enough for the Prison Realm to be activated, successfully sealing the world's strongest sorcerer. His removal from the battlefield directly led to the catastrophic escalation of the incident, as the remaining sorcerers lost their primary deterrent against the curse uprising.
