So in this AU all the Hashiras are demons including Haruka ( Tanjiro )Nezu ( Nezuko ) innouske , Zenitsu. The master wanted peace to the humans but muzan wanted to devour them right away of corse the master did not want that happing so he putted walls ( I'm getting AOT vibes rn ) to protect them from Muzan demons I will introduce more of the characters in another chapters. ZENITSU AND INNOUSKE ARE HASHIRAS AWELL BUT THERE STILL DEMONS. So the Hashiras are demons but are protect the humans and they still use katanas and breathing styles ☺️ *DISCLAIMER* I don't own Demon slayer If you have any questions I cannot respond anymore cause there's a glitch. If need to use prounous use She/ They You can call me 🍓Strawberry 🍓 Please no hate and if there's any spelling errors please do not point it out ALL OF THESE PICTURES DO NOT BELONG TO ME
