The fan-favorite crossover comedy Isekai Quartet is coming back for a third season. The new trailer shows the return of familiar characters along with some fresh faces and brand-new theme songs to set the mood. Studio Puyukai is once again handling the production. The chibi-style anime brings together popular isekai worlds and mixes them into one classroom, full of humor, silly chaos, and school-life fun that fans have been waiting to see again.
Isekai Quartet Season 3 Premieres This October With New Trailer and Songs
The third season is set to premiere on October 13, 2025. Much of the main staff from earlier seasons is returning. Minoru Ashina is back as director and scriptwriter. Minoru Takehara continues as character designer and chief animation director. Composer Ruka Kawada is also returning, which means the familiar light and playful tone of the series will stay intact. Fans can expect the same energy they enjoyed in the past.
This season is also adding something new. Characters from The Eminence in Shadow will join the classroom, making the cast even bigger and funnier. With Ainz, Kazuma, Subaru, Tanya, and now the Shadow Garden characters, the series has even more room for funny clashes and absurd moments. The charm of Isekai Quartet has always been in its “what if” scenarios, and season 3 looks ready to push that even further.

With the premiere date now set, Isekai Quartet 3 promises another season of lighthearted chaos that isekai fans won’t want to miss.
