The day of Aoba's tryout for the women's national team, Ko and Azuma see her off at the train station. During the journey, Midori, Matsuyama, and Kojima tell her that her play during Satomi's match with Oka a year ago inspired Satomi to win the girl's high school championship. At the tryouts, the Satomi players point out Shimano from Ryuo, who looks and plays like her cousin from the boy's team. In Tokyo, Ko waits out the rainy day in Akane's soba shop. During her batting tryout, Shimano is overshadowed by Oka's Ozaki. Kojima and Oka's Sawaguchi watch Aoba's pitching and are impressed by how her speed and control have improved. Before the coaches announce the results, Shimano insists on showing how she bats against a pitcher instead of a machine, and draws Aoba as her pitcher. Aoba strikes her out with three pitches, and Aoba, Matsuyama, and Midori all pass the first round of tryouts. At Seishu's practice the next day, Aoba pitches to Azuma, a challenge they both enjoy, until he hits her with a line drive.
