A humorous and ambitious anime crossover in which 4 Isekai anime shows get transported to a school by a red button, all clustered together in one classroom.
Weeb: Isekai Quartet is better than Dream 9 Toriko X One Piece X Dragon Ball Z.
Another weeb: How come?
Weeb: Well it’s because Isekai characters from other shows interact with each other and have crazy adventures.
Shorthand for being teleported into a fantasyworld, often via a collision with a motor vehicle.
Ryan: Poor Devin got isekai'd last week. He had to kill a dark lord and everything!
Bryan: He should really learn to look both ways before crossing the street.
