Ace of the Diamond act II -Second Season- now has a return date: its second cour premieres in Japan on October 11, 2026. The regular broadcast is scheduled for Sundays at 5:30 p.m. on the six-station TV Tokyo network, with AT-X also carrying the series. The comeback centers on the West Tokyo qualifier final between Seido and Inashiro, the matchup official promotion has consistently positioned as the main event of this half of the season.
For viewers who stopped with the first cour, the pickup point is straightforward: it ended with Episode 13, “An Endless Road”/“Michi Hateshinaku”, which aired on June 28. The next new material therefore continues from that cliffhanger. The October 11 date announcement does not state an episode number, but the series order points to Episode 14; supporting that reading, the September 8 advance screening was announced with Episodes 13 and 14.
When cour 2 premieres and where it airs in Japan
The September 8 announcement confirmed an October 11, 2026 premiere at 5:30 p.m. on the TV Tokyo network. The official schedule also lists AT-X for Sunday broadcasts. The anime's broadcast and streaming page lists Netflix and a range of Japanese services as distribution options.
- Japan premiere date: October 11, 2026.
- TV Tokyo and affiliates: Sundays at 5:30 p.m.
- AT-X: also confirmed on the Japanese schedule.
- Streaming in Japan: Netflix is prominently listed, alongside other services on the official site.
The schedule can be checked on the official broadcast and streaming page and in the September 8 Crunchyroll News announcement.
Where the story resumes: from Episode 13 to Seido vs. Inashiro
Warning: this section contains spoilers only for material already aired in the first cour.
The first cour ran for 13 episodes and finished on June 28. Episode 13 sets up the West Tokyo final, once again pitting Seido against Inashiro. The official synopsis shows Seido preparing for the rematch and highlights one major concern: Kawakami has elbow pain, and medical testing finds inflammation in his right arm.
That is the story state that matters before the return. The semifinal against Ichidai Sankou is over, and since June the second cour has been promoted as the portion that follows the championship game against Inashiro. The September key visual reinforces that focus by placing Seido's players opposite Inashiro ace Mei Narumiya.
If you want the exact refresher without replaying many episodes, the official Episode 13 synopsis is enough to re-establish the setup. Crunchyroll also carries Episode 13 in its catalog, with several subtitle options listed.
What to remember before returning, without going into future spoilers
- The final is Seido vs. Inashiro. Production materials confirm that cour 2 is built around the West Tokyo qualifier final.
- Mei Narumiya is again the central obstacle. Inashiro's ace is positioned as the direct counterpart to Seido's core players in the promotional material.
- Kawakami's condition matters. Episode 13 leaves his right-arm inflammation as an important variable in how Seido manages its pitching staff.
- Sawamura and Furuya remain crucial. The cour 2 visual highlights both Seido pitchers among the players challenging Narumiya.
- You do not need to replay the whole season. For a fast refresher, the final episodes of cour 1—especially 12 and 13—cover the transition from the semifinal to the championship game.
New confirmed cast member: Daisuke Sakuma as Shinichiro Saotome
The September 8 announcement added Daisuke Sakuma of Snow Man to the cast. He will voice Shinichiro Saotome, a second-year Inashiro player. The character description presents him as a right fielder, versatile left-handed hitter and highly talented player who saw limited action in his first year because of injuries.
The addition fits the focus of this half of the season: rather than opening a side story, it expands Inashiro's roster specifically for the final. The announcement and the new visual both make clear that Narumiya and his teammates are not merely background opposition.
Cour 2 opening and ending themes
The artists for the new theme songs are also confirmed. GLAY will perform the opening and OxT the ending for cour 2. The song titles had not been announced in the official materials reviewed as of September 8. The artist confirmation was published in June on the anime's official website.
What is confirmed about streaming—and what is still missing internationally
The distribution picture needs to be separated by territory. In Japan, streaming has been announced: the official site lists Netflix and other local platforms, and September 8 coverage reports distribution following the television broadcast. That answers the question for the Japanese market.
For international viewers, however, the September 8 announcement does not provide a country-by-country simulcast calendar. Crunchyroll already carries the series and currently offers all 13 episodes from the first cour, but an existing catalog listing does not by itself constitute a formal promise that every new episode will arrive at the same date and time in every region.
Viewers outside Japan should therefore treat the Japanese date and time as confirmed and check the regional schedule of the platform they plan to use. The same caution applies to Netflix outside Japan: the official distribution list is Japan-focused and should not automatically be read as a guarantee of simultaneous global availability.
Checklist before October 11
- Rewatch Episodes 12 and 13 if you need a quick bridge from the semifinal to the final.
- Remember that the return is centered on Seido vs. Inashiro and another showdown with Mei Narumiya.
- Keep Kawakami's physical limitation from Episode 13 in mind.
- Expect Daisuke Sakuma as Shinichiro Saotome on Inashiro's roster.
- GLAY is confirmed for the opening and OxT for the ending; the track titles still await announcement.
- Before premiere day, check Crunchyroll, Netflix or another service available in your country for a regional cour 2 schedule.
In short, the essentials for Ace of the Diamond act II -Second Season- are already set: an October 11 Japanese return, a Seido vs. Inashiro final, a new cast addition and new opening and ending artists. For viewers outside Japan, the main remaining question is practical rather than narrative: which service will carry cour 2 in each region, and how closely its release will follow the Japanese broadcast.
