Gathered Representatives!
Goro becomes a batting pitcher for the Japanese Senior team to help further his development against Professional players, but he also hopes that he can gain enough respect on the mound to become a player for the Japanese team in the World Baseball Classic. At home Taiga and Goro work with each other to improve his outside pitching control and his fastball's speed. The problem is he forgets to tell Shimizu about all of it, but her dream of following the baseball player keeps her from getting too upset about it.
