Isekai Quartet - Wikiwand (2025)

Isekai Quartet (Japanese: 異世界かるてっと, Hepburn: Isekai Karutetto) is a Japanese anime series that is a chibi-style crossover between the light novel series KonoSuba, Overlord, Re:Zero − Starting Life in Another World and The Saga of Tanya the Evil, all published by Kadokawa Corporation.

One day, a magic button suddenly appears. The protagonists from KonoSuba, Overlord, Re:Zero, and The Saga of Tanya the Evil all press the button occasionally, unintentionally and move to a parallel world — another brand new isekai — where a new story featuring high school life begins. Soon, they are joined by protagonists from The Rising of the Shield Hero and Cautious Hero: The Hero Is Overpowered but Overly Cautious.
