During the intraschool ranking matches, Momoshiro, Inui, and Tezuka all end up in the same block, meaning that one of them will not become a regular. With the other blocks finishing up, some of the regulars secure their spot on the team. However, when Momoshiro is defeated by both Tezuka and Inui, he ends up being the one knocked off the team. Later, Inui, who has been collecting data on his teammates all this time, attempts a victory over the intractable Tezuka.
A medida que se acerca el torneo regional, el club de tenis de Seigaku decide celebrar otro torneo intraescolar para determinar los ocho habituales Seigaku que representarán a su escuela.
