Luculia is a graduate of the Auto Memories Doll Training School and a novice Auto Memories Doll. Luculia and Violet became friends as fellow classmates at the training school, and she is the one who helped Violet graduate and earn her licence. She is shown to be a kind and considerate person who is willing to go out of her way to assist others, such as her offering Violet some of her food the first day they met as well as attempting to help her write a letter to Gilbert. Despite a tragic backstory, she is shown to carry a positive attitude and cheerful demeanor when around other people, but tends to be more quiet and solemn when alone. She is expressive and sociable, but she struggles to communicate her own feelings, particularly regarding her brother.
