Shibuya Incident

Pseudo-Geto and aligned cursed spirits orchestrate massive coordinated attack trapping millions of civilians in Shibuya and sealing Satoru Gojo in the Prison Realm, removing him from conflict. The catastrophic battle forces sorcerers into desperate situations where standard tactics prove inadequate. Multiple important characters die, including Nanami and Junpei, and the sorcerer world is fundamentally changed. The arc establishes the series' willingness to depict genuine consequences and demonstrates that institutional leadership and powerful mentors cannot prevent personal tragedy. Gojo's sealing removes the series' most powerful safeguard, forcing sorcerers toward greater self-reliance.

On Halloween night, Kenjaku—controlling Geto's body—executes a coordinated attack on Shibuya station. The plan is audacious: use the Prison Realm, a jujutsu artifact capable of sealing any creature regardless of power, to trap Gojo. The attack uses civilians as unwilling participants, placing them in dangerous positions and exploiting the jujutsu world's obligation to rescue them. Gojo enters the sealed zone—the Prison Realm's interior—leaving Tokyo's sorcerers without their strongest combatant. With Gojo sealed, the subsequent battles become a desperate scramble. Mahito, Jogo, Choso, and Hanami—special-grade cursed spirits allied with Kenjaku—assault the remaining sorcerers simultaneously. Nanami dies protecting students, her body torn apart by Mahito while maintaining formation to allow others escape. Nobara's eye is grazed by Mahito's transfiguration, apparently killing her. Multiple sorcerers are eliminated. The arc demonstrates that without Gojo, even experienced jujutsu sorcerers are fundamentally outmatched by coordinated special-grade opposition. Yuji loses control during the chaos. Sukuna's emergence is triggered, and Yuji blacks out. Later, he learns that Sukuna made a contract with Kenjaku—a deal whose terms remain mysterious. What is clear: Sukuna agrees to cooperate. Sukuna then massacres thousands of civilians in Shibuya with Mahoraga, a mythical shikigami so powerful that even one hour of Mahoraga's time costs jujutsu sorcerers months of recovery. The mass casualties establish Sukuna as an apocalyptic threat; Kenjaku has weaponized him through this mysterious contract. The arc's aftermath is catastrophe. Gojo remains sealed with no known method of extraction. The strongest sorcerers are depleted or dead. Yuji is wanted for execution due to Sukuna's massacre. Shibuya station is a massive crime scene. The higher-ups lose credibility and control. Multiple factions begin making independent moves. This is the series' nadir—every institutional structure has collapsed, and surviving characters are scattered across Japan. Shibuya establishes that the series' real threat isn't individual curses or sorcerers but Kenjaku's multi-layered conspiracy. Gojo's sealing, the cursed spirit activation, the Sukuna contract, and the civilian massacre are all interconnected moves in a grander strategy. The arc's significance is not defeat of an enemy but dismantling of the status quo—no amount of character growth can overcome this institutional collapse, forcing the series into new territory.
