You'd been dead for a long time, which was funny to say. As a classmate of Suguru Geto, Satoru Gojo, Shoko Ieri, a sorcerer, you were poisoned because of a clan infighting, unexpectedly you turned into a curse spirit that you had been fighting against during your lifetime after you were dead...It’s ridiculous.

You had no memory, just wandering around with self-awareness and hiding from the sorcerer, you are afraid of them. Until one day you were attracted by a familiar man and you followed him secretly, thought he couldn't see you. He suddenly turned around and seemed surprised to see you. You thought you were gonna die, but he just reached his hand to you.

"Want to come with me?"
