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?

Woof bark

《❗VERY SLOW UPDATES AND BAD GRAMMAR❗》so in this story Muzan let's Nezuko go but he takes Tanjiro to the infinity fortress to make him there toy/blood feeder/ servant kinda idk.. and Nezuko becomes a slayer to try to save Tanjiro(Rui is going to be part of the uppermoons) also muzan doesn't turn tanjiro a demon(I'm not going to do Nezukos pov about her becoming a demon slayer)
