Kyo is the main protagonist of the story, pushed into cross-dressing as a boy by her father so she can play on the boy's basketball team in her new high school, much to her consternation. On the first day of practice, she quickly finds herself disliking fellow first-year Chiharu for his seemingly superior attitude, and then, to her surprise (and dismay), it turns out that they're roommates! But, is he really as bad as he seems?
