This is a swap au, so Daki swapped with Nezuko, Gyutaro swapped with Tanjiro zenitsu didn't really swap lives, he is now Kanao's brother Inosuke swapped lives with Zenitsu, but he is still aggressive yet does not wear his boar mask Shinobu swapped lives with Kanae Aoi swapped with noone And the rest of the Hashiras don't swap, unless you have a suggestion for who should swap with who Everyone's Gender is the same as well, so only life swap, no gender swap. I hope this make sense, if not, it may make more sense in the story Disclaimer : some things that happened in the anime, may not be added into the book Hope you like the story, and if you do check out my other book 'Demon Zenitsu' or 'Demon slayer Pictures' Also I'm bad at writing combat/fighting sencesPublic Domain
