A troublesome personafication of the sun's heat that gained it own consciousness after it longed to know what love was like. After making a contract with Katsuki, it lived many different lives with its immortal body which included but aren't limited to: a tree that observed the world for centuries, a bird that flew to explore new places, a dog who learned what loss was, and eventually as a boy who died in a war. Sometimes, he takes refuge in the cottage located in Katsuki's god realm to escape reality. As Kamui grew wiser with each year he lived, Katsuki watched over him and became a motherly figure for him. Kamui learned from centuries of repetitve, countless losses that love was only a curse for an immortal being like him. He despised ever making a contract with Katsuki and is currently avoiding any contact with Katsuki due his unstable, confusing emotions. Currently, he uses his authority as a demigod to guide spirits who are lost. Kamui refuses to open up to other people and often plays pranks on humans when they cannot see him. Little does Kamui know about the Game that Katsuki is participating in, and little does he know of the doppelganger that plans to overthrow Katsuki.
