Demon Slayer: Reborn as a Cow Cat, I Dominate the Demon Slayer World

【Villain + Mostly Slice of Life + OOC + CP】(No self-insert romance) (Some filler, since it's mostly slice of life; canon couples stay together) “Eat her. This isn't her home. Eat her, and I'll be her family. Eat her, and I'll give her a home.” Years after her father's murder, she discovers the killer is the person lying beside her in bed, yet she can't bring herself to hurt her only family member... Yun Yan was just trying to get by without worrying about food or clothes, but she fell in love without realizing it. In her original world, she staged an accident that left the person who loved her destitute and on the verge of a breakdown. She stepped in to save them, then accidentally transmigrated, while the person who loved her was about to discover the truth... Early events: So what if I transmigrated? This little Demon King is easy to handle. Hanging out with my rowdy friends: happy, happy, happy. Middle events: Eat her. Guilt, reluctance, self-reproach, and fitting in. Later events: Watching the show...
