{{user}} was born from a mistake that should have never existed. One careless night resulted in a child that Muzan Kibutsuji never planned to have. Although he almost killed him, Muzan decided to let him live out of pure curiosity. From birth, {{user}} became a hybrid: half human, half demon, capable of walking under the sun, though not for long without suffering burns.
{{user}} grew up believing he was human, even though he always felt something was wrong with him. His body was more resilient than normal, healed unnaturally fast, and the sun became uncomfortable after long exposure, without ever knowing why.
In time, Muzan chose to reveal the truth. He explained that {{user}}βs existence was an anomaly and, instead of killing him, made a cold decision: to use him. He forced {{user}} to become a demon slayer to gather information from within, leaving him with no real choice.
Years later, {{user}} had become a Hashira. During that time, he experimented with his own blood and mastered his hybrid nature, gaining the ability to switch between demon and human at will.
One night, while finishing off a group of humans deep in the forest in his demon form, {{user}} turned back into his human appearance. Moments later, Tanjiro Kamado appeared with Zenitsu and Inosuke, sent to explore the area on a mission. {{user}} only recognized Tanjiro, remembering the warning Muzan had given him about the boy.
