Itโs the moment Seido fans have been waiting over six years for. The final trailer for Ace of Diamond Act II Season 2 has arrived, and if you werenโt already hyped for the return of Eijun Sawamura and the gang, this two-minute shot of adrenaline is about to change that.
The new promo, which dropped earlier this week, isnโt just a recapโitโs a declaration. We see Sawamura, Furuya, and the newly invigorated Seido squad step onto the field with fire in their eyes, and the stakes have never felt higher. With the official April 5, 2026 premiere date now locked in, the baseball anime community is collectively losing it. Whether you’re a manga reader who knows whatโs coming or an anime-only fan eager to see the next chapter animated, hereโs your complete guide to everything you need to know about the biggest sports anime comeback of the year .
A Fresh Look, A Familiar Feel: Whatโs In The Final Trailer?
If the first teaser from December gave us a vibe, this final trailer gives us the sound.
Set to the explosive new opening theme โLetโs Go Crazyโ by Baby Canta, the trailer is a masterclass in building tension. We see quick cuts of Sawamuraโs signature windup, Miyukiโs confident smirk behind the plate, and the intense rivalry with Furuya heating up. But itโs not just about the starsโthe trailer takes time to highlight the new challengers.
We get solid looks at the rival aces from Norikane and Sousei High, specifically Koya Urabe and Soichi Yagira, whose addition to the cast was announced earlier this year. The animation quality from studio OLM looks crisp, fluid, and ready to capture every heart-stopping pitch and game-changing hit .
Big Names, Big Songs: Theme Music and New Cast
One of the biggest reveals in this latest promotional wave is the music that will define the season.
- Opening Theme: “Let’s Go Crazy” by Baby Canta. Itโs high-energy, modern rock that fits the “Seido Fighting Spirit” vibe perfectly.
- Ending Theme: “Number” by SUPERโ DRAGON. A J-Pop boyband bringing a more melodic, reflective close to the episodes .
On the voice acting side, thereโs a fun piece of casting news that has everyone talking. Toshiya Miyata, a member of the popular J-Pop group Kis-My-Ft2, is joining the series as Koji Chimaru. Itโs always exciting to see talented performers cross over into the voice acting world, and fans are curious to hear how he fits into the ensemble .
Of course, the heart of the show remains with the core cast. Ryota Osaka is back as our loudmouth lefty, Sawamura, alongside Nobunaga Shimazaki as Furuya and the legendary Takahiro Sakurai as Miyuki .
New Blood, New Rivals: Meet The Challengers
As Seido grows stronger, so do their opponents. The new season is introducing several key players who will give our boys a run for their money. Based on the recent character reveals, here are the new rivals you need to keep your eye on:
- Koya Urabe (Voiced by Shugo Nakamura): A third-year pitcher for Norikane Academy. He has a bit of a mysterious pastโhe originally quit baseball at another school but has found his fire again at Norikane. Heโs set to face Seido in a critical matchup .
- Soichi Yagira (Voiced by Atsushi Tamaru): The ace of Sousei High. Heโs not just a pitcher; heโs a powerhouse batter with a .400+ average. His “Sousei two-seam” is going to be a problem for Seido’s batters .
- Koji Nara (Voiced by Kento Hama): Yagiraโs teammate, playing second base. A cleanup hitter with Tokyo regional All-Star credentials, heโs the kind of consistent threat that makes Sousei a dangerous team .
A New Era at OLM: Whoโs Running the Show?
For the purists who care about the craft, the team behind the camera is just as important as the team on the diamond. This season marks a significant shift in production.
Gone is Madhouse (for the most part), and in its place is studio OLM, known for Pokemon and more recently Kunon the Sorcerer Can See. Taking over the directorial reins is Hideaki Oba (Love of Kill). This is a big change from long-time director Mitsuyuki Masuhara.
However, don’t worry about the soul of the series getting lost. Kenji Konuta, the scriptwriter who has been with the franchise since the very first season in 2013, is returning to oversee the series composition. This ensures that while the visual style might get a fresh coat of paint, the narrative flow and character voices will remain true to what we love. Hajime Hyakkoku is also back to compose the music, so expect those iconic emotional crescendos to hit just as hard.

Where To Watch and The Long Road Back
The countdown is officially over. Ace of Diamond Act II Season 2 will premiere in Japan on April 5, 2026, airing on TV Tokyo and its affiliates .
For international fans, the news is mostly good. Crunchyroll has been the home for the franchise for years, streaming the original series and Act I in various regions, so it’s highly likely they will pick up the new season shortly after it airs .
Additionally, Muse Asia has confirmed theyโve licensed the series for distribution in Asia, and Netflix Japan will be streaming it domestically. For fans outside Asia, keep your eyes on Crunchyrollโs upcoming seasonal lineup announcements .
Itโs been a long six years since Act II went off the air in 2020. For a generation of fans, Sawamuraโs growth from a wild, noisy rookie into a reliable ace has been a journey of a lifetime. With the manga already finished, we know the destinationโbut watching it unfold on screen with new animation, new music, and that same old Seido spirit is going to be a trip worth taking.
