あらすじ
When her mom goes missing, three-year-old Lotilucia stumbles on a magic crest that transports her to the estate of House Frodium, one of the empire’s most powerful noble families. Little Lottie immediately recognizes Duke Damian Frodium as her dad; he is the so-called “Monster Duke” of demon descent. Once taken into the house, Lottie does her best to stay out of his way. But then she stumbles on a magic book that shows her a story about Duke Frodium’s adopted daughter replacing his dead daughter named Lotilucia! Lottie is shocked but also emboldened by the prophetic tale.
