Isekai Quartet

A strange button pulls familiar heroes, villains, and troublemakers from different fantasy worlds into the same classroom, where daily school routines quickly turn into pure chaos. Instead of grand quests and deadly battles, the focus shifts to short, playful interactions as strong personalities clash over lessons, lunch, and club-like activities.

Its humor comes from seeing well-known isekai characters squeezed into a small, chibi-style school setting that turns their usual roles upside down. With magic, parody, and a light slice-of-life tone, it plays like a crossover comedy built on exaggerated reactions, odd friendships, and the fun of watching very different worlds collide.
