Chapter 90

The Shibuya Incident, Part 8 (⑧) is the ninetieth chapter of Gege Akutami's Jujutsu Kaisen.

Summary
When Gojo is confronted by his best friend, Geto, he's left in complete shock, having been the one who had killed him. A minute passes which allows the Prison Realm to seal Satoru Gojo once and for all.

Plot Details
In a flashback, Geto can be seen talking to Mahito, Jogo, and Hanami about the special grade cursed object, the Prison Realm. He explains that after opening the Prison Realm, they must keep Gojo within a four meter radius. Jogo angrily yells at Geto that he's going to burn him alive. Stating that the task would be impossible for them, even with a thousand human lives would not be able to distract the latter. Geto assures him that when he means one minute, he means one minute within Gojo's mind.

Back at the present, Suguru Geto confronts Gojo which leaves Gojo confused. Gojo wonders if this Geto is a fake but the Six Eyes rejects all the possibilities and confirms that he's the real Geto. Gojo is trapped by the Prison Realm, unable to feel his cursed energy or even move his muscle as Geto taunts him, asking why he'd let his mind wander in the midst of a battle. Satoru Gojo asks who he is as Geto replies he's obviously Suguru Geto, who asks Gojo if he had forgotten about him. Gojo yells at the imposter, asking for who he is, who removes the top part of his head, revealing his brain underneath.

The imposter reveals that his cursed technique allows him to switch between bodies by switching brains, as well as allowing himself to use all the Innate Techniques within the body as well. The imposter thanks Gojo for being so considerate during awkward moments, allowing him to obtain Geto's body. He assures Gojo that the seal will be over soon enough in maybe a hundred and or a thousand years. Gojo prompts "Geto" to remember that Okkotsu beat up the real Geto before. But "Geto" states that Okkotsu can't become the next Gojo.. "Geto" ponders about Yuta and says he doesn't understand what everyone sees in him. Yuta's ability to copy techniques and his boundless amount of cursed energy resulted in him detaining his love one's soul. The imposter then says Yuta can't become the next Satoru Gojo as he tells Gojo goodnight.

Elsewhere, Yuji, who's with Mei Mei and Ui Ui notices something is on his ear, reminiscing of a Mechamaru design. The object suddenly asks Yuji if he can hear him.
