Jujutsu Kaisen 0: Gege Akutami

The prequel to the supernatural exorcist adventure Jujutsu Kaisen!
In a world where cursed spirits feed on unsuspecting humans, fragments of the legendary and feared demon Ryomen Sukuna have been lost and scattered about. Should any demon consume Sukuna`s body parts, the power they gain could destroy the world as we know it. Fortunately, there exists a mysterious school of jujutsu sorcerers who exist to protect the precarious existence of the living from the supernatural!
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?
