Monster Duke's Daughter

Monster Duke's Daughter summary: When Lotilucia's mother disappears, the three-year-old discovers a magical crest that whisks her away to the estate of House Frodium, an influential noble family in the empire. Instantly recognizing Duke Damian Frodium as her long-lost father, Lottie becomes aware of his notorious reputation as the "Monster Duke" due to his demon ancestry. Lottie does her best to steer clear of him upon arriving at the lavish estate, but her curiosity gets the better of her when she happens upon a mystical tome that tells the story of Duke Frodium adopting a replacement daughter named Lotilucia. Though taken aback, the precocious Lottie feels empowered by the prophecy and resolves to enjoy her time on her own terms, regardless of an inevitable fate. New and improved Lottie manages to charm her demonic father and the household staff, but surviving and thriving as the Monster Duke's offspring proves to be an entirely different challenge.
