Their friendship progressed until she disappeared out of nowhere. Years later, he found her once again as they decided to keep the promise they made years ago. might draw this as a manga, but just to draft out the story i'll be writing it in manuscript form Kimetsu No Yaiba: Demon Slayer belongs to Gotouge Koyoharu.
