A girl's life has been changed by one simple mistake that had turned her into a demon and now its her job to protect her younger sister at all costs! (Hey! Its me! The author! So I had changed the story and the characters looks later on in the chapter!) Edit: So I'm like 3 years late, but here to say that I won't edit this story or continue it, as I'm not apart of the demon slayer fandom. I'm not into anime anymore so I'm leaving this story be, for other people to read and cringe abt 😊.
