Yuji Itadori is determined to save the world from cursed spirits, but he soon learns that the only way to do it is to gradually lose his humanity and become one himself! In a world where cursed spirits feed on unsuspecting humans, fragments of the legendary and feared demon Ryomen Sukuna have been lost and scattered. 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 work to protect the fragile balance between the living and the supernatural!

While investigating a series of mysterious deaths, Itadori meets Junpei, a troubled kid who is often bullied at school. However, Junpei is also befriended by Mahito, the culprit behind the bloody incident—a mischievous cursed spirit with dark intentions. Mahito sets in motion a devious plan involving Junpei, hoping to trap Itadori as well!
