Isekai Quartet is a chibi-style crossover anime series that brings together characters from various KADOKAWA isekai light novel series. The first season, which aired in 2019, featured characters from Overlord, KonoSuba: God's Blessing on This Wonderful World!, Re:Zero - Starting Life in Another World, and The Saga of Tanya the Evil. The second season in 2020 added the cast of The Rising of the Shield Hero, and this upcoming third season will introduce characters from The Eminence in Shadow. An anime film, Isekai Quartet The Movie: Another World, was released in 2022.

The button appeared out of nowhere. There weren't any signs NOT to push it... so the solution is obvious, right? Is it a trap or the start of something new and exciting? The crews of Re:Zero, Overlord, Konosuba, and The Saga of Tanya the Evil will find out when they go from their world to another and get stuck in... class?! See what adorable chaos they'll get up to in this collection of shorts!^[1]
