In the seventh inning, Ko strikes out Mishima with pitches reaching the high 150s km/h, though Ko is disappointed he did not show Aoba a 160 km/h fastball as he promised before the game. In the eighth inning, Oikawa tries to repeat the previous year's line drive to Ko, but Ko catches it. In the bottom of the ninth, Ryuo manages to score, sending the game into extra innings, tied 1 to 1. In the top of the 10th, Azuma hits a triple, after which Oikawa intentionally walks Akaishi and Ko, to load the bases with no outs. However, Seishu's last three batters are unable to hit, stranding the runners on base. As Seishu takes the field, Azuma warns Ko to not let Mishima get on base or Ryuo will keep the momentum. With Ko still pitching in the high 150 km/h, Mishima hits a hard line drive to first that Azuma barely catches. Aoba remembers seeing Ko cry while practicing pitching shortly after Wakaba died. In the top of the 12th with two outs, when Ko comes to bat he remembers hitting home runs in the Tsukishima batting cages, and as he does so hits a home run.

7회말. 1점을 따라잡은 류오학원, 2아웃에 4번 타자 미시마 타석. 볼넷이 되어도 상관없는 이 상황에 코우는 미시마에게 정면 승부를 겨루기로 한다. 아오바는 그런 코우를 보며 시합 전에 코우와 했던 약속에 대해 준페이에게 이야기한다. 승부는 헛스윙을 끌어낸 코우의 승리였지만, 아오바는 코우를 거짓말쟁이라 하며 솔직하게 기뻐하지 못한다. 그리고 시합은 1점 차인 상태로 마지막 회를 맞이하게 되는데...
