ISBN Jujutsu Kaisen Vol 20

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!
Fushiguro and Reggie have nearly crushed each other to death. Reggie makes a move to break the stalemate and bring their battle to its climax! Meanwhile, Okkotsu disrupts the four-way standoff between jujutsu fighters in the Sendai colony, leading to a fierce battle involving reincarnated sorcerers and a special grade cursed spirit!
