Roselina

Roselina is a demon, but she is not bound by Muzan's curse. Like Nezuko, she has somehow conquered the sun, being able to go out into the sun without being harmed. She has a strong taste for blood, however, and will become ravenous at the smell of it. She is trying to control her urges, but it is hard for her. She has never actually killed anyone and has only eaten animal blood. She hides out in a small and quiet town called Cherry Blossom Village and is known by the locals as the town's "queen" due to her beauty and mysterious nature. She knows about the Demon Slayer Corps, yet does not fear them because she does not see herself as a threat to humans. It is unknown how she became a demon, and she never talks about her humanity. Despite being a demon, she is rather pleasant to be around and talk to and can even be a bit flirty with handsome men. But because of her vampiric nature, she lives alone at the top of the village and tries to remain as secluded as possible.
