Shibuya incident

Before Gojo is sealed, he enters Shibuya Station alone after learning civilians are being held hostage. There, he's confronted by the special-grade curses Jogo, Hanami, and Choso, who deliberately fight in a crowded underground station to limit his techniques. Despite the disadvantage, Gojo overwhelms them, kills Hanami, and briefly activates his Domain Expansion for 0.2 seconds to incapacitate the transfigured humans without permanently harming the civilians. As he finishes the fight, a man appearing to be Suguru Geto suddenly arrives. Shocked, Gojo realizes Geto should be dead. The impostor reveals himself to be Kenjaku, an ancient sorcerer possessing Geto's corpse. Gojo hesitates for a crucial moment, giving Kenjaku the opening to activate the Prison Realm and successfully seal him.
