Chapter 91

Kenjaku and the curses finally complete what they came for, locking Satoru Gojo inside the Prison Realm. Through a concealed puppet, Kokichi Muta passes the grim news to Mei Mei's group and asks Yuji to carry it further. Speed is everything now, because freeing the sorcerer is the only thing standing between the jujutsu world and total ruin.

Down on the Fukutoshin Line platform, the little ring-shaped device clipped to Yuji's ear suddenly speaks in Kokichi's voice. Yuji nearly tears it off before the message lands: Gojo has been sealed. Inside the Hikarie building, Kenjaku wishes the trapped sorcerer goodnight, and a flicker of the real Suguru surfaces enough to make the body seize the impostor by the throat. Kenjaku is delighted, telling Mahito the theory about body and soul being cleanly divisible cannot hold, while Mahito counters that their wildly different techniques simply place them in separate worlds. The gate closes, and the seal is set, with the Prison Realm only ever holding a single prisoner.

Mei Mei doubts the puppet until Kokichi proves himself by detailing his own death at Mahito's hands on October 19th, explaining that three such puppets were planted and hers went to the team least likely to be a traitor. He warns of a curse user, roughly semi-grade 1, advancing on the platform, and urges them to dismantle the four barriers strangling Shibuya rather than charge straight for Gojo. Yuji is sent back toward Meiji-Jingumae and the surface to spread the word, since the curtains have cut off phones for sorcerers and managers alike.

Kokichi frames the rescue as something only the sorcerers can pull off together, asking Mei Mei to clear Niji Ebina from Yuji's path. Mei Mei accepts but still asks about her payment, even as Kokichi admits that a Gojo-less world would upend both jujutsu society and ordinary life. Ebina arrives with his chained shikigami, and Yuji falls in behind Mei Mei. Back at Hikarie, Choso and Jogo shake off the lingering grip of Unlimited Void, and the Prison Realm thuds to the floor as though impossibly heavy. Within it, Gojo sits among skeletons in a timeless space, owning his mistake yet trusting his allies to set things right.
