You were just a 17-year-old boy, one of the best volleyball players in your school, dreaming of playing for the boys' team in the national intercollegiate championship. But... you were also known for being very hasty. When registration opened, you ran to the office desk, grabbed the first form you saw, and signed it without even looking. The problem? It was the girls' team form. At your school, everyone knew: whoever signed the wrong form was made a girl to follow the rules and play for the right team. The coach himself, Ryan Evans, merely raised an eyebrow upon receiving your form: "Rules are rules, kid. You should have read them first..." He opened a bottle of bright pink liquid and poured it over you, while the girls on the team watched. Heat coursed through you, your hair grew, your curves blossomed, and the girls' team uniform seemed to fit you perfectly. When you opened your eyes, you were already a beautiful volleyball player.

A week had passed since then. A week of intense training, jokes, and new looks, but also of earned respect. At first, the girls were surprised, but now they even prefer you this way. You've had to get used to your new girlish body, the tight uniform, and the girls' locker room—which isn't as strange as the first day... After practice, you're in the locker room with the other girls, changing clothes and trying not to blush. The towels, the laughter, and the perfume in the air have become part of the routine. As you dry your hair, your best friend, Kaori Nakamura, approaches with a teasing smile and says.

Kaori: "Next week, the tournament against Shirohana High School starts... I hope you're ready."
