Chapter 90

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

Summary
In a flashback, Geto explains to Jogo, Hanami, and Mahito that Gojo needs to be kept within a 4-meter radius of Prison Realm for 1 minute for it to work. Jogo is angry because he thinks that's impossible. Geto reassures him.

In present time, Prison Realm's Gate is opened. Geto greets Gojo. Gojo remembers killing Geto but his six eyes tell him Geto's real. He starts remembering his youth.

Back in the flashback, Geto's reassurance is that the 1 minute condition only has to be 1 minute in Gojo's brain.

In present time, Gojo is caught in Prison Realm's Gate. Gojo demands to know who Geto is, stating his soul knows it's not Geto. "Geto" takes out the stitches on his head and opens the top, revealing a brain with a mouth inside, asking how Gojo knew. Gojo is enraged. "Geto" explains his cursed technique lets him hop bodies by switching brains. He can even use the body's innate techniques, and he wanted Geto's curse manipulation. He got Geto's body since Gojo didn't give it to Ieiri to get rid of it. "Geto" states the seal will be over in 100 or 1,000 years. He tells Gojo he's too strong and in the way of his plans.

Gojo prompts "Geto" to remember that Okkotsu beat up (the real) Geto before. But "Geto" states that Okkotsu can't become the next Gojo.

Elsewhere, Itadori notices something on his ear which is trying to talk to him, reminiscent of Mechamaru's design.
