15

Shido tells Daimon that the prefab team has been playing practice games without permission, losing all five times. After a sixth loss, Azuma learns from Tubby who the opponents were. Shido orders the prefab team be disbanded. However, Maeno proposes to instead hold a rematch scrimmage with the losing team's coach losing his job, and Daimon agrees in order to settle things once and for all. When Momiji's mysterious old man visits a prefab team practice, Tubby introduces him as her grandfather. Yuhei Azuma tells his older brother he will get to Koshien for certain, to which Junpei says to have fun with baseball. Because of his differences with Daimon, Miki transfers to another school. The prefab team recruits Aoba for the scrimmage to replace a retired third-year player, and to convince her to play center field instead of pitcher, Akaishi has her bat against Ko. After watching the prefab team practice, Azuma deliberately injures himself to avoid playing in the scrimmage and tells Daimon to prove that he has enough other good players to take him to Koshien.
