Isekai Quartet brought some of the most beloved isekai protagonists together in one outrageous crossover that’s equal parts sitcom and parody. Characters from KonoSuba, Overlord, Re:Zero, The Saga of Tanya the Evil, and more have laughed, argued, and learned together in a comically chaotic school setting. After the franchise’s third TV season wrapped in late 2025, many fans are now wondering: Is Isekai Quartet Season 4 happening? Here’s the latest based on available information.
Series Recap
Isekai Quartet is a comedy crossover anime that brings together characters from multiple popular isekai franchises into a single, absurd setting. Instead of continuing their original plots, these characters are suddenly transported into a chibi-style parallel world and enrolled in a strange school.
The series thrives on contrast. Overpowered villains, tragic heroes, and comic relief characters are forced to attend classes, participate in school events, and interact in ways that would never happen in their original stories. The humor comes from clashing personalities, meta jokes, and exaggerated reactions to mundane school life.
Season 1, which aired in April 2019 with 12 episodes, introduced characters from KonoSuba, Overlord, Re:Zero, and The Saga of Tanya the Evil. The season focused on setting up the classroom chaos and establishing comedic dynamics.
Season 2, released in January 2020 with 12 episodes, expanded the crossover by adding characters from The Rising of the Shield Hero and Cautious Hero. The jokes became sharper, and the character interactions grew more layered.
After the 2022 theatrical movie, Season 3 aired in late 2025, adding characters from The Eminence in Shadow. This season leaned harder into self-aware humor and franchise parody, proving the concept still had room to grow.
Is Isekai Quartet Season 4 Confirmed?
As of now, no official confirmation has been made for Isekai Quartet Season 4 by the anime’s production committee, Studio Puyukai, or Kadokawa. While three seasons and a movie exist, there has been no formal announcement regarding a fourth TV season.
The complexity of adapting multiple franchise characters and coordinating rights across series appears to slow down forward planning. However, the third season’s inclusion of a wider cast points to continued interest from the creators and audience alike.
Season 4 Release Date: What Fans Should Know
Since there is no official renewal yet, Isekai Quartet Season 4 does not have a confirmed release window or teaser. If a new season is greenlit, it would most likely arrive after 2026, given the time required for coordination across multiple franchises. Current industry discussion places a potential return in late 2027, though no timeline has been confirmed.
Potential Story Direction: What Could Season 4 Cover?
There’s no official plot information for Season 4, but the series’ premise offers endless possibilities:
- New crossover scenarios with cameos from other Kadokawa-published anime
- Expanded character interactions drawing on current isekai franchises
- Ongoing school hijinks and meta humor that lampoon anime tropes
The format remains intentionally comedic and light-hearted, offering parody riffs on each represented franchise rather than a continuous, dramatic plotline.
Isekai Quartet Anime Ratings
Though not a conventional narrative drama, Isekai Quartet has maintained a loyal fan following:
- IMDb rating: approximately 7.0/10
- MyAnimeList rating: approximately 7.42/10
The MyAnimeList score reflects consistent audience enjoyment, especially among fans familiar with the original series. The anime is praised for character chemistry rather than narrative depth.
Where to Watch Isekai Quartet
All seasons of Isekai Quartet are available on Crunchyroll, where both subtitled and dubbed versions have been streamed internationally. The series has also been licensed on platforms like Funimation (North America/UK/Australia) and Muse Communication (Southeast Asia) depending on regional availability. The theatrical movie Isekai Quartet: Another World may be available for rent or purchase on services such as Apple TVand Amazon in some regions.
Cast & Characters
Isekai Quartet features a massive ensemble drawn from the parent franchises. Key returning cast members span:
- Kazuma Satou, Aqua, Megumin, Darkness (KonoSuba)

- Subaru Natsuki, Emilia (Re:Zero)
- Tanya von Degurechaff (Saga of Tanya the Evil)
- Naofumi Iwatani, Raphtalia, Filo (Shield Hero)

Season 3 expanded the roster further, and if a Season 4 is produced, it could introduce even more faces from current isekai favorites.
About the Franchise & Crossover Appeal
Isekai Quartet is a unique celebration of Kadokawa’s isekai catalog. It mashes up characters from multiple worlds into one setting, letting beloved protagonists interact in absurd, often hilarious ways. This crossover format bypasses traditional storytelling, letting fans enjoy character dynamics they wouldn’t see otherwise.
Because it doesn’t depend on a single narrative arc, the series is flexible — able to pull in characters from newer titles and keep evolving if demand remains strong.
Final Thoughts: What’s Next After Season 3?
At this point, Isekai Quartet Season 4 has not been officially confirmed, and the series’ future remains uncertain. The crossover concept, however, has shown remarkable staying power, with multiple seasons, a movie, and a global fanbase backing it. If the creators decide to revive the anime again, there’s clearly a world of chaotic, humorous interactions still left to explore.
