Jujutsu Kaisen, Vol. 1 by Gege Akutami

To gain the power he needs to save his friend from a cursed spirit, Yuji Itadori swallows a piece of a demon, only to find himself caught in the midst of a horrific war of the supernatural!

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!

Every sports club wants him to join, but Itadori would rather hang out with the school outcasts in the Occult Research Club. One day, the club manages to get their hands on a sealed cursed object. Little do they know the terror they’ll unleash when they break the seal…
