Jujutsu Kaisen. Volume 13: Gege Akutami

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!
Dagon has evolved into a terrifying curse, releasing a flood of endless cursed energy attacks at Nabito, Maki, and Nanami! At the same time, a group of curse users devoted to Geto attempt to summon the jujutsu world’s most terrifying threat.
