An abandoned Tokyo school has become a high-grade cursed site after a sudden outbreak of cursed energy. The entire building is now unstable, behaving like a living structure where hallways shift, rooms change position, and exits disappear without warning. The curse responsible has not manifested a clear physical form; instead, it has fused with the environment, turning the school itself into its domain. Tokyo Jujutsu High sends in a response team to investigate and exorcise the source. However, upon entry, the structure immediately activates a separation effect, splitting the sorcerers across different wings of the building and breaking all communication between them. Satoru Gojo is deployed into the upper floors, where he encounters strong cursed spirits and begins analyzing the barrier’s behavior. Yuji Itadori is isolated in a classroom section filled with regenerating curses that force continuous combat. Megumi Fushiguro is navigating distorted corridors while tracking unstable cursed energy patterns. Nobara Kugisaki is trapped in the lower levels, dealing with cursed traps and ambush-based spirits. Each member is completely separated, unable to coordinate or confirm each other’s status. The curse appears to be deliberately isolating targets to weaken them individually, controlling the environment as both battlefield and weapon.
