Akaishi visits his old elementary school and remembers Wakaba describing her Koshien dream. Aoba teaches Ko new breaking pitches, which Azuma describes as her way of climbing on the mound in Koshien using Ko's body, and resumes training after her cast is removed. After Ryuo wins the spring Koshien tournament, its coach denies to reporters that he is worried about Seishu in the upcoming summer tournament. Akane becomes a waitress at the Clover Cafe. When Akane visits a flea market in another township, Aoba suggests that Ko accompany her, where in return for Aoba's coaching Ko buys her a garish T-shirt.
