Ace of Diamond Act II Second Season has aired thirteen episodes of its first cour since its April 5 premiere and is headed into its second cour, which debuts October 11 at 5:30 p.m. JST on TV Tokyo and its affiliates, with an AT-X broadcast at 9:00 p.m. JST. The new cour continues the Seido vs Inashiro match.
The second season of Ace of Diamond Act II has been running since April 5, when it premiered on TV Tokyo and its affiliates and on AT-X, with Netflix streaming in Japan and Crunchyroll handling international distribution. Thirteen episodes had aired as of the second cour's promotional push. Hideaki Oba directs the season at OLM, taking over from Mitsuyuki Masuhara, while Madhouse animated the previous Ace of Diamond Act II series. Kenji Konuta returns to oversee series scripts, Yasukazu Shoji is the new character designer in place of Minoru Ueda and Satoshi Tasaki, and Hajime Hyakkoku returns to compose the music.
Coverage through the summer stayed on the second cour's timing and its subject. On June 28 the staff said the cour would premiere in October 2026 on TV Tokyo Network, AT-X, and other broadcasters, and that it would continue the Seido vs Inashiro match, a rivalry the earlier adaptation did not reach. A teaser promotional video followed on August 15 and still carried October as the window.
The date firmed up on September 8: October 11 at 5:30 p.m. JST on TV Tokyo and its affiliates, with an AT-X broadcast at 9:00 p.m. JST and streaming on Netflix in Japan. The same announcement added a key visual centered on the Seido vs Inashiro confrontation and a new cast member, Daisuke Sakuma as Shinichiro Saotome of Inashiro High School. GLAY performs the opening theme and OxT the ending theme for the second cour; both artists have previously contributed songs to the franchise. Takahiro Sakurai as Kazuya Miyuki and Ryota Osaka as Eijun Sawamura are among the returning main cast. The series adapts Yuji Terajima's manga, which ran from 2015 to 2022.
