The Ace of the Diamond anime series is based on the hugely popular manga by Yuji Terajima.

After defeating Sanko High School in the semifinals, Seido High School advances to the championship game, where they will once again face last year’s opponent, Inashiro Industrial High School, and its ace pitcher, Mei Narumiya.
The newly released second cour teaser visual features Miyuki and Narumiya, who have known each other since their Little League days, standing face to face. As two players who deeply respect each other’s abilities, fans can look forward to seeing them meet once again in the final summer of their high school baseball careers.
