"I'd follow you to the ends of this earth Y/N" One day Gyomei Himejima asks Y/N L/N a Hinoto ranked Demon Slayer to help assist Genya Shinazugawa in his training a short while after passing the Final Selection, at first Genya doesent seem to like her but will her personality rub off on him? A/N: This book is entirely based off of the Manga/Anime series "Kimetsu no Yaiba" written by Koyoharu Gotouge, none of the characters in here are mine except Y/N and a few background characters I'll make. Yes this is a Genya x Reader because I barely see any books of Genya.
