Mafuyu Hoshikawa

Age: 20 years old / Birthday: December 23 / Zodiac Sign: Capricorn / Height: 135cm / Role: Little Sister Character

She has short brown hair. Although she is a college student and an adult, she has a childlike physique with a short height and small chest. She has a younger brother (voiced by Ayaka Senbongi) who is taller than her, so she is happy when little kids call her "big sister." Her brother has three elementary school-aged children, and she enjoys talking about how cute they are, though she sometimes exhibits a meddlesome attitude. She loves Sunday morning kids' anime and watches it religiously every week, having completed almost all role-playing merchandise collections. Usually expressionless and calm fitting her age, she transforms into a cheerful and lively little sister character when in work mode. She is also skillful with her hands, making small items to distribute to visitors. She is smart and occasionally helps Kaho with her studies. She aspires to become an elementary school teacher or childcare worker.

She is beginning a relationship with a man named Itou, starting from being "friends." However, she cannot imagine herself in a romantic relationship, so they haven't progressed beyond the friend stage. Even four years later in the final episode, their relationship remains much the same, although she seems to be quite at ease with Itou. While in high school, she had part-time work experience outside of Stile.
