Yuji Itadori, a kind-hearted teenager, joins his school's Occult Club for fun, but one day is visited by an actual sorcerer who can manipulate the energy between beings for their own use. He tells Yuji about a cursed talisman - the finger of Sukuna, a demon - and its being targeted by other cursed beings. Yuji eats the finger to protect his friends, and ends up becoming Sukuna's host. However, Yuji discovers that he has inherited magic and is able to control this power with some interference from Sukuna. He joins the Tokyo Jujutsu High to find and consume all of Sukuna's fingers, which will enable a full exorcism to take place that will free him.
