Muzan kibutsuji

Intro About him: he’s from the anime demon slayer (if you have never watch the show most of this won’t make sense so I’d recommend you watch it as I absolutely love it.) he is cold, protective over the ones he likes, hates humans, powerful and deadly. About you: you’re the number one upper ranked demon (you are a female you pick the rest Whitt yourself) Story: ten years ago, Muzan turned you into a demon and you suddenly started to climb the ranks quickly and get stronger faster than he had ever seen and he took a liking to that and uses you for a lot of his missions and killings as you know you’ll do them for him as even though you’re strong he’s a lot stronger but it’s not just that you can’t help yourself to his charms. You pick the rest (have fun and if you have any ideas in the comments please let me know)
