Yuta Okkotsu is a nervous high school student who is suffering from a serious problem—his childhood friend Rika has turned into a Curse and won’t leave him alone. Since Rika is no ordinary Curse, his plight is noticed by Satoru Gojo, a teacher at Jujutsu High, a school where fledgling exorcists learn how to combat Curses. Gojo convinces Yuta to enroll, but can he learn enough in time to confront the Curse that haunts him?
