She is the third daughter of five sisters. She is characterized by her semi-long hair parted diagonally to cover her right eye and the headphones she always wears around her neck. Her image color is blue. Among the five children, he is good at social studies.
He has a cool personality with few words, but he is very honest with people he trusts and acknowledges his fondness for Futaro. Like Futaro, she is a terrible athlete and a poor cook, but she is the best at disguising herself as one of the other sisters. Her grades are better than the other sisters.
She is a Rekijo who became a great fanatic of the Warring States period because of a video game, but she has kept this unusual hobby a secret from the other sisters for a long time because she was aware of it. She opens her heart to Futaro, who encourages her to confront her hobby, and she begins to develop a liking for him. At first, he is dry and emotionally inexpressive, but he gradually becomes more talkative and expressive.
After moving up to the third grade, she starts working part-time at a bakery to become a "woman who can cook well," which Futaro says he likes.
