Chapter 91

The Shibuya Incident, Part 9 (⑨) is the ninety-first chapter of Akutami Gege's Jujutsu Kaisen.

Summary
Something on Itadori's ear tries to talk to him, and Itadori almost squishes it but it states it's Mechamaru. Mechamaru reports Gojo has been sealed.

"Geto" is talking with Gojo. Gojo speaks provocatively to the real Geto (Suguru). "Geto" is surprised as his hand squeezes his neck. He says to Mahito that the body is the soul and the soul the body, even though Mahito thinks the soul came first. Mahito counters by suggesting it doesn't have to be the same for everyone. "Geto" restrains his rebellious hand while commenting that techniques dictate their own worlds.

Gojo tells them to just get it over with, so Geto closes the Gate. Gojo is now inside Prison Realm, a cube Geto holds.

Elsewhere, Mechamaru's little puppet explains that the real Mechamaru was killed on Oct 19 by Mahito. The puppet is a contingency plan for if Gojo is sealed, and he theorized Mei Mei and Itadori were unlikely to be moles. Mechamaru points out that curse users are coming to kill them. Mei Mei wants to ignore them and go to Gojo, but Mechamaru explains the situation has changed with 4 curtains around Shibuya. Mechamaru pleads with Mei Mei to listen. Mei Mei acquiesces.

Mechamaru tells Itadori to go back to Meiji-Jingumae and get to Shibuya from aboveground to tell the other Jujutsu sorcerers that Gojo's been sealed. Mechamaru tells Mei Mei to help Itadori get through and manage things down there. Ui Ui chooses to stay with his sister. The curse users arrive.

At B5F in Shibuya, "Geto" is forced to let go of the Prison Realm cube, which crashes into the ground. Inside the cube, Gojo observes that time doesn't pass where he is, but is looking forward to seeing how the others (implied to be Itadori, Fushiguro, and Kugisaki) handle the situation.
