Ace of the Diamond Second Season

あらすじ

The second season of Diamond no Ace. After the National Tournament, the Seidou High baseball team moves forward with uncertainty as the Fall season quickly approaches. In an attempt to build a stronger team centered around their new captain, fresh faces join the starting roster for the very first time. Previous losses weigh heavily on the minds of the veteran players as they continue their rigorous training, preparing for what will inevitably be their toughest season yet. Rivals both new and old stand in their path as Seidou once again climbs their way toward the top, one game at a time.
