ダイヤのA OVA

Before they were regulars on Seidou High's roster, brothers Haruichi and Ryousuke Kominato took very different roads onto the team, and this three-episode OVA goes back to show both of those roads. It also follows Youichi Kuramochi's turn from delinquent troublemaker into a trusted shortstop, and pitcher Norifumi Kawakami's struggle to believe he belongs on the same mound as aces like Kazuya Miyuki and Eijun Sawamura. It adapts two manga one-shots as side stories to the main Ace of the Diamond TV series.
