The protagonist who transmigrated after dying from overwork. She now inhabits the body of a three-and-a-half-year-old girl who is the daughter of the former Duke's much-younger brother, making her the little aunt (little ancestor) of the household and grand-aunt to all the younger generation. She has an adult mind trapped in a toddler's body, uses acting and playing dumb to survive dangerous situations, and is navigating a treacherous noble household where multiple people want her dead. She has two crooked pigtails and a pale face.
