Persistent and Diligent
Seido est en mauvaise posture face à Ugumori. Furuya les a laissés prendre une avance de 3 points sur un home run dès la première manche. Les batteurs de Seido ont du mal à remonter au score. C'est au tour de Miyuki d'affronter Umemiya. Parviendra-t-il à inverser la tendance ?

Ace of the Diamond Second Season
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. Needed now more than ever before, Furuya and Eijun must be determined to pitch with all their skill and strength in order to lead their team to victory. And this time, one of these young pitchers may finally claim that coveted title: "The Ace of Seidou."
