High school student Yuta Okkotsu suffers from being frequently bullied, when one day, his bullies are gravely injured by a Cursed Spirit that clings to him. The higher-ups of the Jujutsu Society wish to have the boy killed, as his curse is a dangerous spirit. However, a teacher at Tokyo Jujutsu Technical High, Satoru Gojo, recruits Yuta to join the school in November 2016, thus saving him. During his first mission with Maki, Yuta successfully summons Rika on his own for the first time to save them from a Cursed Spirit. Three months pass in his school training, and he grows close to Maki, Toge, and Panda. One day, on a mission with Toge, the boys are attacked by a high-level Curse. The man behind the attack was Suguru Geto, a previous student and old friend of Gojo's, who defected from the school and killed over a hundred innocent people on a mission. Geto attempts to get Yuta on his side so they can make use of Rika, but Yuta refuses when he insults Yuta's friends due to unsettled circumstances. Geto declares war to activate a portal to the under-world: he will release a thousand Curses upon the city to remove non-sorcerer humans, as he believes them to be undeserving and beneath sorcerers.
