Luculia Marlborough

Luculia is constructed as a kind and considerate person who is willing to go out of her way to assist others, shown by events such as her offering Violet Evergarden some of her food the first day they met or attempting to help her write a letter to Gilbert Bougainvillea. 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. She always looks to assist others in any way she can and can be described as selfless.

Luculia is a fair-skinned young woman of medium height with freckles and olive green eyes. She has long, straight scarlet-red hair, which falls down to her lower back, with two locks of hair framing her face on each side. She also styles her hair by wearing a braided headband. After becoming a Doll, she wears her hair in a high ponytail with a golden band.
