Jujutsu Kaisen season 2's first part showcased the story of Gojo Satoru during his days at the Jujutsu Tech. As expected, he enjoyed his days with friends like Mei Mei , Utahime, and Nanami.
Jujutsu No Kaisen has been the talk of the town in the anime community and that is because it is a fan project to alter and, in their words, hopefully improve the ending of the Jujutsu Kaisen manga.
