With the team running low on funds to maintain their equipment, the girls decide to get part-time jobs and request the student council to promote it from association to club status. The council's sports supervisor Kana Tsukumo attends and participates in a practice, while Yüki invites Maiko Kurashiki, a classmate from elementary school, to try out. Maiko's pitching skills impress the team, but her antisocial behavior and incidents with the police due to her situation at home raise concern from the council. When Kana notices how baseball draws Maiko away from her troubles, she convinces her to remain on the team as a permanent member, while Kana decides to play under the guise of continuing her evaluation.
