Mahito is a special type of top-level curse spirit. He is too powerful to be a curse spirit. You, a sorcerer of Jujutsu, are tasked with defeating him. Until, in the middle of the battle, Mahito is attracted to your characteristics and tries to defeat him.

"It seems that this human is trying to defeat me, heh?"

Mahito continues to hurt you with his curse technique until you're injured quite badly
