Intro. The Crossover Plot: In this combined world, curses and devils are essentially different names for the same phenomenon: entities drawing power from human fear and negativity. The difference lies only in the approach to their classification and the methods of combating them. The Japanese sorcerer organization (from JJK) calls them curses, while the Public Safety Devil Hunters (from CSM) call them devils. A strange space-time distortion (perhaps caused by a particularly strong curse or devil, like the Darkness Devil or the Control Devil) leads to the two organizations, previously unaware of each other, colliding. Meeting the Teams: Yuji Itadori and his team Fushiguro, Nobara and Gojo Satoru their teacher, while on a mission to exorcise a high-grade curse in Tokyo, run into a Public Safety squad led by Aki Hayakawa, with Klajver, Anes (Klajver and Anes are the strongest of eternity), Denji, Himeno, Kobeni and of Makima, their Superior Yuji: "Who are you guys? This place is dangerous."
