Isekai Quartet is a Japanese anime series that debuted in 2019 and is known for bringing together characters from beloved isekai anime. It features protagonists from KonoSuba, Overlord, Re: Zero – Starting Life in Another World, and The Saga of Tanya the Evil. These shows have amassed huge popularity globally, with their novels selling over 16 million copies and the Blu-ray/DVD versions of the anime reaching over 500,000 units in Japan. The success of these individual series contributed to the immense anticipation for the crossover series, Isekai Quartet.
The anime’s first season was quickly followed by a second season in 2020, and the franchise gained further traction through streaming platforms such as Netflix Japan, Funimation, and Crunchyroll. Fans eagerly awaited a third season following the second season’s conclusion on March 31, 2020, and the wait is ongoing even after more than 4 years of its last season finale. Let’s explore the details about the anime, its movie, and the potential third season.
What is the Plotline of Isekai Quartet?
Isekai Quartet delivers a unique twist on the isekai genre by blending comedy with a school-life setting. The story begins when the main characters from four different anime worlds—Re: Zero, Saga of Tanya the Evil, Overlord, and KonoSuba—press a mysterious button that teleports them into a shared alternate world. In this world, they attend high school together, resulting in hilarious situations that poke fun at their original series and their personalities.
The story includes lighthearted events like naming class representatives, talent shows, and field trips. It thrives on meta-humor and references, making it essential to be familiar with the original anime to fully appreciate its jokes. If you haven’t watched all four series, it’s recommended to do so before diving into Isekai Quartet.
Which Characters Could Appear in Season 3?
In the second season, characters from The Rising of the Shield Hero and Cautious Hero: The Hero is Overpowered but Overly Cautious joined the mix. With such a diverse cast, fans are always excited about potential new additions. Speculations have included characters from Bofuri and Plunderer. Additionally, some fans have expressed hopes to see characters from No Game No Life in the series. However, given licensing complexities and the timeline of No Game No Life, this remains unlikely.
As of now, there is no concrete information about new characters for a potential third season, and the creators have remained tight-lipped about any expansions beyond the movie.
Will there be an Isekai Quartet Third Season?
When the second season wrapped up in 2020, fans were thrilled by the announcement of a sequel in the works. However, this sequel turned out to be the movie Isekai Quartet: Another World, which was eventually released on June 10, 2022. The film picks up where the series left off, continuing the story with the same beloved characters embarking on a fresh adventure.
Despite the excitement surrounding the movie, there has been no official word on a third season of Isekai Quartet. One prevailing theory behind the delay is that the show may be waiting for new seasons of popular anime like Re:Zero and The Saga of Tanya the Evil to air first. While Re:Zero has already returned with its third season, The Saga of Tanya‘s new season might not arrive until 2026.
Since the anime is an original work, not adapted from any manga or light novel series, it doesn’t face the usual limitations tied to source material. This gives it the freedom to potentially continue beyond what has already been established. Moreover, the anime has a dedicated and sizable fanbase, making it strong enough to support a new season. Its active presence on platforms like X and its impressive following of 75,000 fans indicates a loyal audience, especially in Japan. While its global popularity might not be overwhelming, the Japanese fanbase alone could be enough to warrant another season.
When is the Release Date of Isekai Quartet Season 3?
As of January 9, 2025, there has been no official confirmation regarding the production or release of a third season of Isekai Quartet. The announcement of the movie in 2021 and its release in 2022 seem to have taken the place of earlier expectations for a third season. While fans remain hopeful, Studio Puyukai has not prioritized continuing the series in episodic form as of now.
Here’s a quick summary of the release timeline:
Season | Episodes | Release Date |
Season 1 | 12 | April 9, 2019 |
Season 2 | 12 | January 14, 2020 |
Movie: Another World | – | June 10, 2022 |
Given the franchise’s popularity and the continued demand from fans, it’s possible that new content—whether in the form of a movie, OVA, or another project—could be announced in the future. If the series is renewed, a potential third season may take several years to develop. The biggest theory surrounding the delay is that it will likely arrive after the new seasons of the series that inspired it. Considering typical production timelines and the lack of concrete news, the earliest a new season might be announced and produced could be late 2026 or beyond. For now, the third season remains speculative, but fans should stay tuned for updates.
In the meantime, if you haven’t seen the movie yet, we highly recommend checking it out. As an essential part of the Isekai Quartet franchise, Isekai Quartet: Another World offers a continuation of the series that is worth watching!
Isekai Quartet: Another World Movie
Directed by Minoru Ashina and produced by Studio Puyukai—the same team behind the anime—Isekai Quartet: Another World delivered a satisfying continuation of the series. The movie follows the group of characters as they are transported to a new world. The film retains the comedic essence of the series, delivering an engaging experience for fans. The entire cast from the first two seasons returned for the movie, including voice actors from KonoSuba, Re: Zero, Overlord, and Saga of Tanya the Evil.
Fans appreciated the movie for staying true to the franchise’s comedic roots while introducing new elements. However, its release further fueled speculation about the fate of a third season.
