Oracle Status: Airing Split-Cour Broadcast

The dust never settles long on the sacred clay of the pitching mound. After years of quiet anticipation following Act II's initial run, Eijun Sawamura's journey roared back to life when Studio OLM took over the dugout from Madhouse under director Hideaki Oba. The first cour launched Seidou's relentless summer campaign in April, reigniting the electric battery between Sawamura and Miyuki before heading into a planned mid-season breather. Now, the final stretch of the regional qualifiers looms directly ahead. With key animation finalized and voice recording wrapped, the franchise is locked in to deliver its high-stakes second cour across TV Tokyo's airwaves this October.

Oracle Prediction: Ace of Diamond Act II Second Season returns with its second cour on October 11, 2026.

Frequently Asked Questions

Yes, the anime received an official renewal under the title Ace of Diamond Act II Second Season. Production was greenlit to adapt the remainder of the Act II storyline following the conclusion of the 2019 to 2020 run.

The new season entered active broadcast on TV Tokyo in April 2026, with the production team completing episodes for its second cour. Animation studio OLM took over production under director Hideaki Oba, transitioning the show out of early development and into full broadcast rollouts.

Extended hiatuses have been primarily driven by the pacing and completion of Yuji Terajima's original manga source material. Because the anime closely adapts match-by-match tournament arcs, the production committee had to wait for the manga serialization to conclude in late 2022 before planning a full sequel.

Studio OLM is handling animation production for the new season, succeeding Madhouse and Production I.G. The shift in animation houses came alongside a director change, with Hideaki Oba stepping in while veteran series scriptwriter Kenji Konuta returned.

No canonical anime spin-offs or narrative expansions are currently in active development. The franchise remains entirely focused on adapting the mainline high school baseball saga created by Yuji Terajima.
