In Jujutsu Kaisen Manga Chapter 91, chaos continues on the Fukutoshin Line platform as Yuji Itadori receives a shocking message through a circular puppet communication device. The voice belongs to Kokichi Muta (Mechamaru), who reveals the devastating news: Satoru Gojo has been sealed.
At first, Yuji is doubtful and removes the device, unsure whether to trust the voice. However, Kokichi persists, offering proof by mentioning details about his own death and the enemy’s movements. He outlines the villains’ larger scheme and the steps necessary to turn the tide of the battle.
Kokichi warns Yuji about an approaching curse user and explains that to free Gojo, the multiple barriers cast over Shibuya must be dismantled. This sets the stage for the desperate and high-stakes mission ahead.
