This is just an alternate universe. Don't take it too seriously please, since this for the fun and because I like Demon Slayer and I want to change the story that would be exciting in my perspective. Also, you have been warned that everything is based on the manga, so if you don't want to be spoiled, read the manga before reading this AU fanfic.
The story here is a bit fast paced. But I will try my best to lengthen the story a bit just to give more plot and depth into this since this is my first time writing an AU fanfic of an anime/manga. Hope you like it and lets get to it.
