Eijun getting excited
She gives him the opportunity to visit the Seidou High School Baseball Team to watch their practice and is totally excited about what he sees there.

It does not take long until he came across Azuma Kiyokuni, a talented batter. Azuma is yelling at his teammate for cowardly pitching. He says if he isn’t even going to try, he should go home to his farmhouse.

Miyuki and Eijun forming a battery
Sawamura – who favors friendship – gets angry and picks up a fight with him. You can't play baseball by yourself after all. Rei takes the chance and contrives it, that Sawamura plays together with Miyuki Kazuya and Azuma. While Sawamura is warming up Rei tells Miyuki that Sawamura's pitches are special and arouses his curiosity.
