Whistle!

As the younger brother of Japanese soccer star Seisuke Kanou, Kyousuke was always expected to grow as a soccer player at the same pace his brother did—an expectation that proved too difficult to meet. Having fallen behind, he now lives in the shadow of his brother's success. Entering his freshman year at Jouyou Akanegaoka High School, Kyousuke vows never to play soccer again. However, Miki Tsujiwaki, the captain of the girls' soccer team, and Mori Kazuto, the manager of the boys' team, recognize Kyousuke's potential and want to see his return to the game for their own reasons. With an opportunity to play soccer again, Kyousuke must either remain steadfast in his decision to abandon the sport he once loved, or allow himself to reignite that flame to become the best striker in the world.
