The second cour of Ace of the Diamond Act II -Second Season has officially received a Japanese premiere date of October 11, 2026. Alongside the announcement, the anime revealed a new key visual and confirmed an additional cast member, giving fans a closer look at what is coming next in the baseball series. The anime is also streaming on Crunchyroll.
The announcement comes as the ongoing adaptation prepares to continue its latest season. Rather than introducing a completely new story, the upcoming cour will carry forward the series’ focus on Seido High School’s baseball team and its pursuit of success against some of the strongest opponents in the sport.
New Visual Highlights the Rivalry Ahead
The newly released key visual centers on the Seido players as they prepare to face Narumiya Mei, the ace of Inashiro Industrial. The image places the rivalry at the heart of the next cour, reinforcing the competitive tension that has defined the series’ baseball matches.
Narumiya is not a new opponent for the team. His presence gives the visual a clear sense of an important rematch, while also reminding viewers that Seido’s journey is built around overcoming increasingly difficult challenges.
The official announcement does not reveal the full details of the next match, so the visual should be understood as a preview of the rivalry rather than a confirmation of its outcome.
Daisuke Sakuma Joins the Cast
The second cour will also introduce Shinichiro Saotome, who will be voiced by Daisuke Sakuma of the idol group Snow Man.
Sakuma has previously appeared in anime roles including Kaito Hibiki in You and Idol Precure, Shin Kohazame in Kill Blue, and Michiru Hazama in Cardfight!! Vanguard.
The casting announcement adds another recognizable voice to the series’ expanding lineup. However, the available report does not provide further details about Saotome’s role in the story, so his importance to the upcoming matches remains to be seen.
