Mafuyu Hoshikawa (Maw-Foo-You How-Shi-Kah-Wah) is another waitress at Stile who is actually a 20-year-old college student, but plays the younger sister character because of her petite figure. Her real personality is mature and she rarely shows emotion, but easily gets excited whenever her favorite series, Aisatsu (Magical Frill in the anime), is involved. She has a younger brother who is taller than her, and she has always wanted a younger sister, although she will not include Kaho because of Kaho's body figure. Although she plays a younger sister character, she has a degree of contempt towards lolicons, and once turned down a customer who asked her out because she believed he was only interested in her because of her young appearance.
