Kyo Aizawa is very excited about attending Seisyu Academy, which is famous for its adorable girls' uniforms. Her excitement is crushed, however, when she opens the package containing her uniform to find a boy's uniform. Her father explains to her that, as Seisyu Academy is also famous for its boys' basketball program, he enrolled her as a boy, so she can fulfill his own dream of becoming an NBA basketball star. To make matters worse, she has to stay in the dorms, and her roommate is the same boy she came to hate at tryouts.
