this is probably gonna be my favorite story🤭 I put a lot of thought into this day and night even in my dreams 😤 So like yoriichi is demon king as he betrayed his brother and became a demon climbing to the top and taking the kings place. Yoriichi turned Muzan into a demon taking nezukos place. Tanjiro, nezuko, zenitsu, and inoskue are in the butterfly mansion other than the top three everything in the same. The hashira and everything. But upper 1,2,3 are just random people- Kokushibo, akaza, and douma the main 3 now. Muzan is female cuz why not It will make more sense if you read it-
