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! 
Sukuna reveals that he is the Disgraced One whom the Angel wants to kill. While Itadori grapples with this terrible news, Kenjaku has set in motion plans involving various nations, throwing the culling game into further confusion! To make matters worse, Kenjaku then shows up at the Tombs of the Star Corridor where Master Tengen exists in seclusion!
