In Jujutsu Kaisen Manga Chapter 90, the sinister plan to seal Satoru Gojo comes to light with the introduction of the Prison Realm — a living barrier fashioned from the remains of the ancient Buddhist monk Genshin. This cursed object possesses the terrifying ability to trap even the most powerful sorcerers.
Prior to the Shibuya Incident, Geto (Pseudo-Geto) revealed the specifics of their strategy to his allies. For the Prison Realm to successfully activate, the target must remain within a four-meter radius for one uninterrupted minute. This condition initially alarmed Jogo, who doubted anyone could hold Gojo in place for that long. However, Geto cryptically reassured him, implying that his definition of “one minute” wasn’t strictly bound to conventional time — suggesting a trick or hidden tactic in their plan.
The chapter foreshadows the dangerous gambit awaiting Gojo as the Shibuya Incident unfolds.
