《❗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)

Yoriichi had once been the best swordsman. Even as an Omega, he was feared by Demons. But choices led to his leave. What choices might have forced this conclusion? His love for the Demon King, Muzan Kibutsuji. His one and only mate. His destiny. (Cover Drawn by me) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (This is a story following Tanjirou as the child of Yoriichi and Muzan. Will be a long series I do, following through the years of Tanjirou's growth. Drama, fluff, and multiple relationships are guaranteed in this adventure.)

! MANGA SPOILERS ! Read the title None of these are mine lol Have fun
