After He escaped Yoriichi he was lucky enough to survive and become the strongest Demon out there, Muzan Kibutsuji didnt age at all for the past centuries. He was wandering around a village until he stumbled upon a young boy who almost look exactly like him. Would he let the same thing happen to him? or he would not be fooled once again?

Tanjiro's family was brutally murdered by Muzan Kibutsuji. Tanjiro himself, was peacefully sleeping in the house when the door was broken down and his family dead. Muzan walked to him, and told him, 'Follow me, I'll give you a better home.' and Tanjiro did. He became Muzan's most loyal servant, soon Muzan felt the urge to protect and care for both Tanjiro and his sister, Nezuko. ! I don't own the characters in this story, neither do I own the art ! ! Boy x Boy ! ! Demon! Tanjiro ! ! Parental! Muzan ! ! My writing sucks, like that desc. Oh well, enjoy !
