Episode 45: That's My Line!

When Seishu wins another game in the tournament, Mizuki complains because it means putting off camping with Aoba. Because she is not feeling well, Akane does not go to work nor to the game, which worries Akaishi. Based on Aoba's coaching, Ko adjusts his pitching form during the next game, which sacrifices control but gives him a speed near 160 km/h. Despite his walking many batters, Seishu wins to advance to the quarterfinals. Ko tries to explain to reporters how Aoba is important to himself and the team, even though she cannot play in tournament games. Akane enters the hospital to be tested for an unspecified illness, which disturbs Akaishi's focus. When Aoba visits her, she is startled by Akane repeating something Wakaba once said about Ko. During the quarterfinal game, Akaishi is still distracted, but with Ko's improved control while still maintaining his speed, plus Azuma's batting, Seishu wins.
