The Isekai Quartet Season 3 anime could continue the comedy and humor of Re:Zero, KonoSuba, Overlord, and The Saga Of Tanya The Evil.

Back on March 31, 2021, the official Twitter account for the anime series officially announced that an Isekai Quartet sequel was already in production. But the format of the sequel wasn’t specified at the time.

Fast-forward to July 2021 and the Isekai Quartet: Another World movie release date was confirmed for late Spring 2022. Of course, there’s no reason why there can’t be both a third season and an Isekai Quartet movie.

But the real question is which new isekai characters will find their way into Isekai Quartet 3.

After all, the official announcements made it pretty obvious that The Rising Of The Shield Hero’s Raphtalia and Naofumi are temporary characters. On the official website, the new characters are listed as “guest characters” and not permanent additions to the main cast.

The BOFURI Season 2 anime was also confirmed to be in production, so Maple and Sally could come from BOFURI: I Don’t Want to Get Hurt, so I’ll Max Out My Defense. Cautious Hero’s Seiya and Ristarte also enjoyed a brief cameo in the second season and they were voiced by Japanese voice actors Yuichiro Umehara and Aki Toyosaki from Cautious Hero: The Hero Is Overpowered but Overly Cautious.

But will either duo join the cast for Isekai Quartet Season 3? Based on the isekai anime released in 2020 alone, Isekai Quartet 3 has many character options for a sequel. It seems like every day, another new anime adaptation is announced for the ever-growing Isekai genre.

Japanese publisher Kadokawa is intent on milking the currently popular Isekai genre for all its worth based on its financial results.

In 2019, anime quarterly profits rose due primarily to licensing income from isekai anime, so Kadokawa announced the intent to produce at least one Isekai anime adaptation per season.

In early May 2021, Kadokawa announced that they intended on creating at least 40 anime projects per year by 2023, an increase of 20 percent from 33 titles.

The primary purpose of the Isekai Quartet anime series is to be a blatant marketing platform for promoting ongoing popular series where Kadokawa publishes the books or manga.

For example, The Rising Of The Shield Hero Season 3 has already been confirmed.

But the focus will always be on the mainstays. The Re:Zero Season 2 anime has already been released and Re:Zero Season 3 seems very likely since the producer has already openly discussed the third season. KonoSuba Season 3 seems very likely since a new anime project has been confirmed.

The Overlord Season 4 release date is in 2022 in addition to a new Overlord movie. Similarly, The Saga Of Tanya The Evil Season 2 was also announced in 2021.

Over the long haul, it’s not a matter of whether Kadokawa would want to produce the Isekai Quartet Season 3 anime, it’s a matter of how.

This article provides everything that is known about Isekai Quartet Season 3 (Isekai Quartet 3) and all related news. As such, this article will be updated over time with news, rumors, and analysis. Meanwhile, let’s delve down into what is known for certain.

Which new characters will Isekai Quartet 3 introduce?

Even before the second season of Isekai Quartet was announced, it was pretty obvious that Shield Hero’s characters would be introduced. Shield Hero was, by far, the most popular series licensed by Kadokawa that was adapted into an anime in 2019.

The 2019 isekai anime included the Wise Man’s Grandchild (Kenja no Mago) anime. However, the series wasn’t nearly popular enough to justify a chibi Shin Wolford even though it would have been funny to watch the clueless character create OP chaos.

On the other hand, reviews of the late 2019 Cautious Hero: The Hero Is Overpowered Bu Overly Cautious (Shinchou Yuusha: Kono Yuusha ga Ore Tueee Kuse ni Shinchou Sugiru) have been fairly solid.

The isekai misadventure is not quite a straight comedy due to the heavy drama plot elements. However, the goddess Ristarte and her champion Seiya would be perfect for the Isekai Quartet Season 3 cast so it’s no surprise they have already been featured in the second season.

Ristarte first showed up in Episode 8 for a brief cameo while working a food stall. Then both Seiya and Ristarte made their appearance in Episode 11 where they join the School Festival.

On the other hand, Cautious Hero Season 2 still hasn’t been announced and the original light novel author has moved on to focusing on the Full Dive: The Ultimate Next-Gen Full Dive RPG Is Even Shittier than Real Life! light novel series. Therefore, it seems unlikely that Seiya and Ristarted will be back as guest characters.

2020 anime provided way many more options, not even halfway into the year. The Plunderer anime’s Licht Bach and Hina provide a mix of serious SciFi fantasy and “man of culture” humor. But since that anime wasn’t renewed it doesn’t seem likely they’ll be included.

(Sorry, the 2021 That Time I Got Reincarnated As A Slime Season 2 is owned by Kodansha, not Kadokawa.)

The question is whether BOFURI’s Maple and Sally or Infinite Dendrogram’s Ray Starling and Nemesis would fit in with Isekai Quartet Season 3.

Although Kadokawa licenses both, they are technically not isekai since both stories are about gamers playing a VRMMORPG.

Arguably, they are both quasi-isekai since the main plot takes place in another world, but that’s stretching the genre.

Still, if only one of these anime can get into Isekai Quartet 3 then the clear choice is BOFURI: I Don’t Want to Get Hurt, so I’ll Max Out My Defense.

Reviews of the BOFURI anime have been more positive, and the plot is more clearly focused on comedy.

Besides waiting until something new becomes popular, Kadokawa could dip down into its franchise portfolio. The obvious choice would be Shiro and Sora from No Game No Life.

Anime fans have been clamoring for the No Game No Life Season 2 anime to be produced for years.

Kadokawa is also behind Sword Art Online: Alicization. Again, SAO doesn’t technically qualify as isekai, but since we’re considering BOFURI, why not?

The SAO: Unital Ring light novels provide a direct sequel to the Alicization story arc it’s likely that Sword Art Online Season 4 will eventually be animated. Therefore, Kirito, Asuna, and Alice could be dropped in as a squabbling love triangle.

Honestly, the biggest potential is for Kumoko from the 2021 So I’m A Spider, So What? anime. The Kumoko resonated with anime fans and her comedic antics would fit in perfectly with the Isekai Quartet cast.

Isekai Quartet 3 release date prediction: Will the anime return in 2023?

As of the last update, Kadokawa, Studio PuYUKAI, or any company related to the production of the Isekai Quartet 3 anime has not officially confirmed the exact Isekai Quartet Season 3 release date. However, the production of another Isekai Quartet sequel was announced by the final episode of the second season.

Once the news is officially confirmed, this article will be updated with the relevant information.

In the meantime, it’s possible to speculate about when the Isekai Quartet Season 3 premiere date will occur in the future.

The biggest issue is whether the leaked Isekai Quartet movie is the promised sequel or if both a film and Isekai Quartet Season 3 are in production at the same time.

If it’s the former, the Isekai Quartet Season 3 release date will be pushed out into 2023 or beyond. If it’s latter, then the third season could come out in 2022, as well.

Let’s just hope Kadokawa doesn’t make fans wait too long to know the Isekai Quartet Season 3 release date. Stay tuned!
