The high-stakes world of Seido High baseball returns to the spotlight as the production team for Ace of Diamond Act II Second Season released a new teaser video. The footage offers a glimpse into the second cour of the current season, which is set to continue the intense athletic drama when it premieres this October on TV Tokyo and AT-X.

This season marks a shift in production, with director Hideaki Ōba taking the helm at studio OLM. While the series maintains its pedigree with returning series script supervisor Kenji Konuta and composer Hajime Hyakkoku, the visual direction has been refreshed under character designer Yasukazu Shōji. The current season, which holds a solid 8.02 rating on MyAnimeList, serves as the latest chapter in a long-standing franchise that began with Yūji Terajima’s original 2006 manga.

Fans looking to catch up on the series' history have plenty of ground to cover. The franchise includes the original 2013 television anime, the 2015 second season, and the 2019 Ace of Diamond Act II adaptation, all of which established the series as a staple of the sports genre. With the manga concluded as of 2022, viewers are eager to see how the animation team adapts the remaining source material for this ongoing sequel.

For those following the manga in English, the series is currently available via K MANGA, with Mad Cave Studios' Nakama Press imprint planning a physical 3-in-1 omnibus release beginning in March 2027. As the Seido team pushes toward their next goal, the October premiere promises to bring the same intensity that earned the original manga a Kodansha Manga Award.
