Nakanishi recruits Ko for a rematch of the sandlot game from fifth grade. When Ko warms up with what he calls a few soft pitches, Nakanishi has him play right fielder instead, claiming he wants a friendly game. Meanwhile, when Aoba plays catch with her little sister, Momiji, she is startled to learn that Momiji can handle her hardest throws because Momiji has helped Ko practice. Akaishi, now captain of the junior high school baseball team, watches the sandlot game and is reminded of Wakaba's boasts about Ko's abilities. With Ko's fielding and batting, his team wins in a close game. Afterward Nakanishi learns that Ko did not join the baseball team, despite his surprisingly fast fastball, because Nakanishi had been kicked off it for fighting. During practice, Aoba and Akaishi discuss unsettling rumors about the Seishu High School baseball team, which has had a second straight losing year. In his office at Seishu High School, Acting Principal Shido tells a man dressed as a coach that he is pleased with his plans.
