Fujibayashi Kyou (藤林杏) was a third year high school student (class 3-E), and was Ryou's twin sister. She was a very strong, violent girl, always protecting her sister. But she was usually cheerful and kind to most others.

Kyou was the class representative of her class, but she didn't always follow the rules. She rode a moped to school (which wasn't allowed by the school rules.) When she got violent, Kyou usually threw a hard and heavy dictionary. Kyou also had a baby boar (named Botan) as a pet. Botan came to school quite frequently. Kyou was good at cooking.

Kyou's voice is done by Hirohashi Ryou (広橋涼).
