Yuta Okkotsu is an anxious high school student who is dealing with a significant problem—his childhood buddy Rika has been transformed into a curse and refuses to leave him alone. Satoru Gojo, a teacher at Jujutsu High, a school where aspiring exorcists learn how to resist curses, notices Rika's struggle since Rika is no ordinary curse. Yuta enrolls after being persuaded by Gojo, but will he be able to learn enough in time to overcome the curse that plagues him?
