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! 
Itadori closes in on Sukuna thanks to the help of Miguel and Larue, two members of Geto's faction. Despite getting weaker, Sukuna pulls off a black flash attack and begins to recover! As the ultimate battle unfolds, Itadori uses black flash himself in order to awaken his potential!
