5 Critical Updates On Overlord Season 5: Is Ainz Ooal Gown Returning In 2026?

Overlord Season 5 is arguably the most anticipated continuation in the Isekai genre, with millions of fans eagerly awaiting the next chapter in Ainz Ooal Gown's conquest. As of December 2025, there is still no official, public release date announcement from Studio Madhouse or Kadokawa, but the silence has been broken by significant, highly credible production news that points toward an inevitable return.

The primary reason for the delay in a formal announcement is the recent focus on the big-screen adaptation, Overlord: The Sacred Kingdom movie, which premiered globally in late 2024. However, reliable industry sources have reported that Overlord Season 5 has already been greenlit for production, shifting the conversation from "if" to "when." Based on the light novel schedule and typical anime production timelines, the earliest realistic projection for the Season 5 premiere falls into the 2026 window.

The Overlord Season 5 Release Date: Unofficial Greenlight and Timeline Prediction

While the official channels remain tight-lipped, the most significant news regarding a fifth season dropped in September 2024. Industry news leaker @SugoiLite, known for accurate scoops, reported that Overlord Season 5 had been officially greenlit for production.

This unofficial confirmation is a massive relief for the community, as it means the series' continuation is secured, even if the release date is still a mystery. The key factor influencing the announcement and release timeline is the recent theatrical project.

• Official Status: Not officially announced by Kadokawa or Studio Madhouse.
• Production Status: Reportedly "greenlit for production" as of September 2024, indicating the planning and pre-production phase is underway.
• Projected Release Window: Given the Sacred Kingdom movie's release, the need to allocate resources, and the typical 18-24 month production cycle for a major anime series, the earliest realistic release window is Late 2026 or Early 2027.

The Sacred Kingdom Movie: The Real Reason for the Season 5 Delay

The biggest factor dominating the Overlord anime schedule is the standalone feature film, Overlord: The Sacred Kingdom. This movie adapts the highly popular Holy Kingdom Arc (Light Novel Volumes 12 and 13), a major deviation from the previous seasons' direct continuation.

The movie's production, marketing, and distribution took center stage throughout 2024, with its Japanese release in September 2024 and North American release in November 2024. The decision to adapt this arc as a movie, rather than a TV season, was a strategic one, likely to give Studio Madhouse more time to develop the final arcs of the series and to capitalize on the theatrical box office.

Crucially, the movie’s successful completion frees up the production team, including director Naoyuki Ito, to fully focus on the television series. The reported greenlight in late 2024 aligns perfectly with the end of the movie's main production and promotional cycle.

What Will Overlord Season 5 Cover? The Light Novel Roadmap

The Overlord anime has historically followed the source material, the Light Novels (LN), with each 13-episode season adapting three volumes. Season 4 adapted Volumes 10, 11, and 14 (skipping 12 and 13 for the movie). The movie covered Volumes 12 and 13. This means Season 5 will be faced with a significant task: adapting the remaining, and final, arcs of the series.

The Final Arcs of Ainz Ooal Gown

The original author, Kugane Maruyama, has confirmed that the Light Novel series will conclude with Volume 18. This puts immense pressure on Season 5, as it will likely adapt the final four volumes of the story, which could mean a longer season or a more condensed adaptation.

The likely volumes to be adapted are:

• Volume 14: The Witch of the Ruined Country (Partially covered in Season 4, but key elements may be revisited.)
• Volume 15: The Half-Wood Elf God-kin (Part 1)
• Volume 16: The Half-Wood Elf God-kin (Part 2)
• Volume 17: The Celebration of Sorcerer Kingdom (Reportedly announced for release in Autumn 2025).

The final Volume 18 would then be covered in a potential Season 6 or a final movie, depending on the pacing. However, given the author’s desire to conclude the series, it is highly possible that Season 5 will attempt to adapt Volumes 14 through 17, and then the final volume will be a grand finale project.

The newly announced Volume 17, titled "The Celebration of Sorcerer Kingdom," is a highly anticipated release scheduled for Autumn 2025. Anime production often waits for the final source material to be available to ensure a complete and accurate adaptation. If Volume 17 releases in late 2025, and Volume 18 follows in 2026, a 2027 anime release date becomes even more probable.

What to Expect: Plot Predictions for Season 5

With the Holy Kingdom Arc (Volumes 12 & 13) now covered by the movie, Season 5 will pick up the threads of Ainz’s consolidation of power and the growing threats to the Great Tomb of Nazarick. The main focus will shift to the Elven Kingdom and the final confrontations with the remaining powerful entities in the New World.

Key Storylines and Entities to Watch:

• The Elven Kingdom: Following the events of the earlier volumes, Ainz's gaze turns toward the Elven Kingdom. This arc introduces new formidable characters and deepens the world-building around the powerful God-kin, characters who possess a fraction of the power of the original Six Great Gods.
• The Sorcerer Kingdom's Expansion: Expect to see Ainz Ooal Gown continue to rule the Sorcerer Kingdom with an iron fist, utilizing his loyal Floor Guardians—Albedo, Shalltear, Cocytus, Demiurge, Aura, and Mare—to execute his plans. The story will explore the political and military fallout of the Holy Kingdom's fate.
• The Slane Theocracy: This nation is the primary human antagonist that poses a long-term threat to Nazarick. Their movements and intelligence gathering regarding Ainz's true power will become a central tension point.
• New World Heroes: The remaining heroes and strong individuals of the New World will likely make their final stand, realizing the overwhelming existential threat posed by the Sorcerer King.

The overall tone of Season 5 is expected to be one of escalating conflict and the final stages of Ainz's master plan for world domination. The anime will continue to balance the dark, ruthless nature of Ainz's actions with the comedic slice-of-life moments inside Nazarick, primarily involving Momonga and the complex relationships with his creations.

Topical Authority: Overlord Production History

To understand the likely timeline for Overlord Season 5, it's helpful to look at the historical production gaps of the series, all produced by Studio Madhouse (or related staff):

• Season 1 (2015): Adapted Volumes 1–3.
• Season 2 (2018): Adapted Volumes 4–6. (3-year gap)
• Season 3 (2018): Adapted Volumes 7–9. (Immediate continuation)
• Season 4 (2022): Adapted Volumes 10, 11, and 14. (4-year gap, complicated by the pandemic and movie pre-production)
• The Sacred Kingdom Movie (2024): Adapted Volumes 12–13. (2-year gap from Season 4)

The four-year gap before Season 4 was an outlier. The current timeline suggests that with the movie complete and a greenlight secured, the production for Season 5 is likely following the faster track of a major studio's main project. However, the final light novel volumes' release in 2025/2026 will be the ultimate determinant. The most optimistic prediction places the release in late 2026, while a more cautious and realistic forecast would point to early 2027, ensuring the highest quality animation for the series' grand finale.
