Re:Zero, Overlord, Saga of Tanya the Evil, and KonoSuba are four of the most popular isekai anime out there. Combined, they have sold over 500,000 DVD and Blu-Ray discs between them. And to celebrate, these four anime are getting a special crossover. However, it won’t just be any poster or special smartphone app, no, it will be an actual anime, and it’s titled Isekai Quartet.

In the anime, a magic button appears to create a new isekai world which brings the four series together. Kinda makes you wonder how the characters will be interacting, huh? Unfortunately, the staff have only revealed some of the four anime’s main characters, and haven’t confirmed the others yet. This means that it still ain’t clear if KonoSuba’s Megumin and Darkness, or Re:Zero’s Ram and Rem will be part of the anime.

Pure Pure Purea Desu Overlord shorts’ Minoru Ashina is directing the anime, with Studio Puyukai doing the animation production. Also, expect plenty of hilarity from this new anime too!
