KonoSuba Season 4 Is Coming in 2027, and It Is Changing Studios Again

KonoSuba turned ten this year, and Kadokawa marked it the way you would expect a franchise with this much goodwill to mark it: a packed anniversary event at Pacifico Yokohama on July 26, 2026, a promotional video, and the announcement everyone in the building was there for. Season 4 is real, it is dated to 2027, and it is changing hands again.

That last part is the interesting one.

The headline: 2027, no month yet

Season 4 was first teased back in January 2026, so the existence of another season was not the news. What the July 26 event added was a release window, a staff list, and a teaser visual. The window is "next year," which in practice means somewhere in 2027 with no season or month attached. Given that Kadokawa put the announcement inside a tenth anniversary celebration rather than a dedicated production reveal, I would read that vagueness as honest rather than evasive. The show is early.

The main cast is untouched, which for this series is close to non-negotiable. Jun Fukuyama is back as Kazuma, Sora Amamiya as Aqua, Rie Takahashi as Megumin, and Ai Kayano as Darkness. Ten years in, these four performances have become the actual identity of the franchise. KonoSuba is a comedy that lives entirely on delivery timing, and there is no version of this show that survives a recast.

ENGI takes over, and that is the third studio in four seasons

Here is the production history, because it matters for how you should set expectations.

Seasons 1 and 2 were made by Studio Deen. The Legend of Crimson film was Deen as well. Season 3, which aired in 2024, moved to Drive, and Drive also handled the An Explosion on This Wonderful World! spin-off. Season 4 goes to ENGI.

Three studios across four TV seasons is a lot of churn for one franchise, and the usual fan reaction to a handoff like this is dread. I think the dread is misplaced here, for one specific reason: Takaomi Kanasaki is coming back as chief director.

Kanasaki directed Seasons 1 and 2 and Legend of Crimson. He was not in the director's chair for Season 3. Having him return in a supervisory role while Manabu Kurihara handles the day-to-day direction is the single most reassuring detail in the announcement, because KonoSuba is a show where the comedic grammar is the product. The joke construction, the reaction-shot rhythm, the willingness to hold on a character's face two beats longer than is comfortable, that is all Kanasaki's fingerprint from the first two seasons. Season 3 was funny but noticeably different in cadence, and a chunk of the lukewarm reaction to it traced back to exactly that.

The other continuity anchors are just as important. Makoto Uezu has been the series composer since Season 1 and is still writing. Koichi Kikuta has been the character designer since Season 1 and is still designing. So the situation is not "new studio, new everything." It is closer to a new production house executing an established creative playbook, with the original architect back in the room.

What ENGI brings to it

ENGI is not a prestige name, and I want to be straight about that rather than pretend otherwise. The studio's track record is mixed. It has turned in perfectly competent light novel adaptation work and it has also turned in seasons that looked rushed. What ENGI does have is a genuine specialty in exactly this lane: Kadokawa-owned isekai and fantasy comedy, produced on a TV budget, on schedule.

That is more relevant than it sounds. KonoSuba does not need spectacle animation. It needs elastic character acting, clean layout, and the ability to sell a punchline visually. Its most memorable sequences are almost never fight scenes. They are Aqua crying, Megumin posing, Darkness monologuing into a void, and Kazuma's face doing the heavy lifting in the corner of the frame. That workload rewards a studio with strong in-betweening discipline and a director who understands timing, not a studio with a huge sakuga bench.

The adaptation question nobody answered

The announcement did not say what Season 4 adapts, which is the one omission I would have liked filled.

For context, Season 3 covered the light novel material through the Kingdom arc territory, and Natsume Akatsuki's novel series completed at volume 17 back in 2020. So there is a defined finish line, and there is a substantial amount of story left between where the anime is and where the books end. The remaining material also gets progressively more plot-forward. The later volumes still function as comedy, but they carry actual stakes and payoffs that the early arcs deliberately refused to set up.

That shift is the real creative challenge for Season 4, and it is bigger than the studio change. A show that spent three seasons training its audience to expect nothing to matter now has to make things matter without breaking the tone that got it here. Uezu has been the one shaping that balance for a decade, which is another argument for reading his return as the most load-bearing credit on the list.

Where this leaves the franchise

Ten years on, KonoSuba occupies an unusual position. It parodied isekai before isekai parody was a genre, the joke has long since been absorbed into the mainstream, and the show survived anyway on pure character chemistry. The spin-offs have kept the brand warm, the anniversary event drew a real crowd, and the fact that Kadokawa is greenlighting a fourth TV season after a studio shuffle says the numbers still work.

I am cautiously optimistic. The staff list reads like a company that identified what went slightly soft in Season 3 and corrected for it. Now they need to actually land the material, and we have at least a year to wait before finding out.

If you have not touched the series since 2024, the practical advice is simple: the anniversary PV is a decent nostalgia hit, and there is no urgency to rewatch anything yet. Save it for whenever Kadokawa finally attaches a month to that 2027.
