(Y/N) has known Muichiro and his brother for as long as she can remember. But what will (Y/N) do when Muichriro loses his memory and she becomes the one thing that took away her childhood friend's brother? Warning: This story will contain some language.

I was so useless, I couldn't do anything, except quake before this man, no devil, in fear. Hello, this fan fiction is going to be where Tanjiro becomes a demon, instead of Nezuko. Before reading this I am going to tell you that this fan fiction will take a totally different path than the anime/manga does. This fan fiction is all purely based on the events in the anime, till chapter twenty, and then afterwards events that are not in the anime, only in manga, will be taking place. ~ Cover Art: @ForeverFireAnime ~Disclaimer: Demon Slayer: Kimetsu No Yaiba does not belong to me, it rightfully belongs to the amazing person, Koyoharu Gotōge. She did such an amazing job, this anime/manga is a masterpiece. So give her all the amazing credit please!!
