Jujutsu Kaisen, Vol. 15 Big Book, Paperback Book, By: Gege Akutami

To gain the power he needs to save his friend from a cursed spirit, Yuji Isadora 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 Roman Sukuma 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! Sukuma is on a murderous rampage. Meanwhile, invaluable Jujutsu Sorcerers have been taken down, and even Kiyosaki falls into Mahito's trap! Feeling the burden of his sins, Isadora finds it hard to keep going, but he rushes off to help Kiyosaki anyway. Can he reach her in time?!
