Isekai Quartet

Isekai Quartet is a comedy short series that brings together characters from four different isekai anime: Re:Zero, Overlord, Konosuba, and The Saga of Tanya the Evil. When a mysterious button transports all four casts to an unexpected location, they find themselves enrolled in the same class and forced to coexist despite their vastly different personalities and goals. The result is a lighthearted slice-of-life comedy that plays on the absurdity of mixing incompatible characters from separate worlds.

The series aired in spring 2019 as a twelve-episode short run, making it an easily digestible watch even for viewers new to some of the source material. While familiarity with at least one of the four parent series enhances the humor, the comedy works standalone through visual gags and character interactions that don't require deep knowledge of each show's lore. The shorts format keeps episodes brisk and the tone deliberately silly—this is comedy first, plot second.

Isekai Quartet functions as a celebration of the isekai genre itself, gleefully poking fun at its tropes while letting beloved characters from different stories play off each other in an entirely new context. If you enjoy ensemble comedy or want a fun palate cleanser between more serious anime, this collection of shorts delivers exactly what its premise promises.
