Tsuyaka Himejima
A good friend and basketball teammate of Kyo's from middle school, Tsuyaka transfers to Kyo's high school during her second year (Kyo's first year) so that they can play on the same team once again, only to be stunned by the news that Kyo is pretending to be a guy! Tsuyaka, from then on, tries to get Kyo to return to her true identity and join the girls team. Unfortunately for her, Kyo has already formed friendships (and a crush) and wants to stay on the boy's team! This creates a conflict of interests that calls into question Tsuyaka's level of empathy, but things work out in the end.
