Akaishi and Aoba visit Akane in the hospital, where she tells them that she promised to go on a date with Ko after the tournament, and that she may require surgery. In the semifinal, Seishu plays Nishikura, a team that has come from behind to win every game by one run. Senda hits a home run on first pitch of the game, and Nishikura scores a run in the first inning as well. Spurred by Akane's worries, Akaishi hits another home run in the second inning. In the eighth inning, with Nishikura having failed to get on base since the second inning, Seishu scores six runs. Nishikura does not score in the bottom of the inning and the game is called for Seishu, 8 to 1. After the game, Ko finally visits Akane in the hospital for the first time, where he praises Akaishi's performance and then asks when her surgery is.
