Ace of the Diamond Act II Cour 2 Sets October 11 Return

Ace of the Diamond act II -Second Season- will return to Japanese television on October 11 with a new visual, a new cast member, and an official streaming plan that international viewers should read carefully.

The official Ace of the Diamond anime site published three updates on September 8, 2026, giving the second cour of Ace of the Diamond act II -Second Season- a firm Japanese premiere date and expanding the project’s event calendar. The announcements are useful to overseas fans because they clarify the domestic broadcast clock and the services named by the production team, while leaving some territory details open.

What Was Announced

The second cour will begin on Sunday, October 11, 2026, on the TV Tokyo six-station network and AT-X. The official broadcast page lists a 5:30 p.m. JST slot on the TV Tokyo network and a 9 p.m. JST slot on AT-X. It also lists repeat broadcasts for AT-X. In practical terms, the first TV Tokyo airing is 8:30 a.m. UTC, although viewers should check their own daylight-saving rules before converting that time locally.

The date announcement also introduced a new key visual. It places Seido High’s players in a confrontation with Inashiro Industrial’s ace, Mei Narumiya. The official description names Eijun Sawamura, Satoru Furuya, Kazuya Miyuki, Haruichi Kominato, and Yoichi Kuramochi among the Seido players facing Narumiya. That is a precise visual signal for the next stage of the baseball drama: the rivalry is moving toward the West Tokyo final and the teams’ route to Koshien.

A second September 8 announcement confirmed that Daisuke Sakuma will voice Shinichiro Saotome, an Inashiro Industrial player. Sakuma’s official comment describes Saotome as a player who appears easygoing but is intensely focused on finding a winning approach. The casting update therefore adds a named voice to the opposing side just as the new visual brings that team back to the center of the promotion.

The site also announced “Ace of the Diamond All-Star Game FINAL: Tokyo Selection vs. Seido” for December 13, 2026, at Meiji Jingu Baseball Stadium in Tokyo. The event is separate from the TV broadcast, but it shows that the franchise’s current promotional plan extends beyond the second cour’s premiere.

Why It Matters

This is more than a routine date card. The second cour is positioned around a specific competitive payoff: Seido’s players facing an opponent they know well, with Narumiya presented as the obstacle in the new visual. The official announcement does not promise an outcome, so it would be premature to describe the match as won, lost, or decisive for the entire series. What is confirmed is that the anime is using this matchup as its next major promotional focus.

The timing also gives fans a clearer way to follow a continuing adaptation. “Cour 2” refers to the next scheduled block of episodes, not a new standalone season. The October date tells viewers when the broadcast resumes, while the new visual and Saotome casting make the return easier to distinguish from the first cour in search results, episode guides, and streaming catalogs.

Sakuma’s casting is notable in a different way. It connects a contemporary entertainment personality with one of the series’ named baseball teams, but the official materials do not claim that his participation changes the production or guarantees a particular audience response. The concrete news is the role itself and the character’s place in the Inashiro lineup.

Context for International Fans

The official on-air notice confirms that Netflix will offer the episodes immediately after the Japanese broadcast, followed by other services. The listed platforms include ABEMA, DMM TV, d Anime Store, Disney+, FOD, Hulu, J:COM STREAM, Lemino, milplus, music.jp, Prime Video, TELASA, TVer, U-NEXT, Anime Hodai, Kantele Doga, NicoNico Channel, Net TV Tokyo, Bandai Channel, and Video Market.

That list is a distribution notice, not a worldwide rights map. The official page does not specify which of those services will carry the second cour outside Japan. Netflix is the clearest service for international readers to check, but local availability, subtitle languages, and the exact release time may vary by territory. The safest reading is that the Japanese broadcast is confirmed and that post-broadcast Netflix streaming is confirmed on the official Japanese schedule; overseas rollout details are not yet confirmed in that notice.

For time-zone planning, the TV Tokyo network slot of 5:30 p.m. JST on October 11 converts to 8:30 a.m. UTC on the same date. The AT-X slot is 12:00 p.m. UTC. Streaming immediately after the Japanese broadcast may not mean that every regional catalog updates at the same minute, so fans should use the local Netflix listing rather than assume a universal simulcast time.

What Happens Next

The next official checkpoints are straightforward. First, fans should watch the anime site and its official accounts for the detailed episode and streaming schedule, especially any territory-specific notice. Second, the production team may release additional information about the second cour before October 11, including promotional video material or further cast details. The September 8 announcements confirm the premiere date but do not state the cour’s episode count, so that remains not yet confirmed.

Finally, fans interested in the live franchise event should note the December 13 All-Star Game FINAL at Meiji Jingu Stadium. The official event page lists ticket application windows beginning October 7, but this is a Tokyo event and the page does not announce an international livestream. Overseas fans should wait for a separate official viewing or distribution notice rather than treating the stadium date as an online event.
