Isekai Quartet 3

Isekai Quartet 3 is a comedy short series that brings together characters from four major isekai anime—Re:ZERO, Overlord, KONOSUBA, and Saga of Tanya the Evil—into one chaotic classroom setting. This season expands the cast with new additions including Alpha and Shadow from The Eminence in Shadow, creating fresh dynamics among the ensemble. The series finished airing in fall of 2025 with eleven episodes total.

The show is structured as a collection of comedic shorts rather than a traditional full-length series, making it ideal for quick, entertaining viewing sessions. If you enjoy slice-of-life humor with a fantasy twist and appreciate seeing beloved characters from different series interact in unexpected ways, this continuation delivers exactly that. The short format means you can jump in during your downtime without committing to lengthy episodes.

The third installment maintains the franchise's trademark blend of comedy and fantasy while introducing fresh comedic opportunities through its expanded character roster. Fans of the previous seasons will find the same lighthearted tone that made the crossover concept work, while newcomers to the Isekai Quartet concept will discover an accessible entry point into this particular brand of ensemble humor.
