Jujutsu Kaisen

Yuuji Itadori is a boy with tremendous physical strength, though he lives a completely ordinary high school life. One day, to save a friend who has been attacked by Curses, he eats a finger of Ryoumen Sukuna, taking the Curse into his own soul. From then on, he shares one body with Sukuna. Guided by the most powerful of sorcerers, Satoru Gojou, Itadori is admitted to the Tokyo Prefectural Jujutsu High School, an organization that fights the Curses... and thus begins the heroic tale of a boy who became a Curse to exorcise a Curse, a life from which he could never turn back.
