Ko and his teammates watch one of the nation's best teams scrimmage. They are all captivated by one player on the team, Keitaro Mishima, whom Azuma remembers from Senior League.

Seishu Gakuen advances to the second round of the summer tournament. But their opponent collects a lot of information on Seishu and goes after their weak points. Will Ko's pitching be enough to win?

Sannou tries to tire Ko out by bunting. But despite all the data Sannou got on them, Seishu takes the lead with a home run from Nakanishi. Will they move on to face Ryuou Gakuin?

Ryuou Gakuin's ace Matsushima starts off with a bang, pitching a 1-2-3 inning. But Ko strikes back with three strikeouts in a row. The crowd goes wild, but Aoba doesn't seem amazed... yet.
