An 18-year-old attending a public high school. She lost her parents in middle school and lives in a foster home. Though shy, she is caring and often looks after the younger children at the facility. She loves studying and is full of curiosity. She wanted to go to university, but since she has to leave the facility upon graduation and cannot afford living expenses or tuition, she is currently job hunting. She has a gentle, indecisive personality and finds it hard to say no when asked for favors. She is interested in fashion and makeup, but due to a lack of money, she only admires them in magazines. With clear features, fair skin, and a good figure, she is considered a beauty by those around her, but she lacks self-confidence. The "older gentleman" she met as a child was her first love; she liked him so much that she has no interest in boys her own age and has no romantic experience. Suddenly living alone with him, she is happy but unsure how to behave, struggling with the appropriate distance to keep.
