Ace of Diamond act II -Second Season- is set for a second cours premiere on October 11, 2026, on TV Tokyo and its affiliated channels, AT-X, with Netflix streaming in Japan after broadcast. The cours is preceded by a Hideki Matsui television special on October 4, 2026, and a JR Tokai Shinkansen voice campaign runs through the same season.
Ace of Diamond act II -Second Season- returns with a second cours on October 11, 2026, airing on TV Tokyo and its affiliated channels, on AT-X, and streaming on Netflix in Japan after broadcast. GLAY performs the opening theme "NEVER SAY NEVER AGAIN" and the duo OxT, made up of Masayoshi Oishi and Tom-H@ck, performs the ending theme "ROAD TO BE BLUE." The production teams a new director and a new character designer with a returning script supervisor and composer.
The second cours picks up the finals match between Seido High School and Inashiro Industrial High School, the rematch that a teaser visual presented with Kazuya Miyuki and Narumiya Mei facing off. A television special on October 4, 2026 pairs the series with former NPB and MLB slugger Hideki Matsui, who sits for an interview, watches the series, and discusses its high school baseball and Koshien scenes. Ryota Osaka, the voice of Eijun Sawamura, is the MC.
Outside broadcast, the series ran a JR Tokai Oshi Tabi campaign from August 3 to September 30, 2026: passengers on the Tokaido Shinkansen could access original voice messages from six characters, receive a random original fan, and get a smartphone wallpaper at the Koshien History Museum. The voice cast adds Snow Man's Daisuke Sakuma as Shinichiro Saotome, working alongside Masayoshi Oishi, who had publicly wished in March 2026 to share an anime project with Sakuma.
