Review of Isekai Quartet

Isekai Quartet represents the most wholesome and pure type of fan service one can write. In other words a spinoff truly made for the fans of not just one franchise but four of them, more specifically KonoSuba, Re:Zero, Youjo Senki and Overlord; kind of like a 2019 equivalent of what Carnival Phantasm was for the Nasuverse back in 2011. It should go without saying that you should have seen at least some and preferably all of these series before watching Isekai Quartet or you will not be able to appreciate this anime for what it is. This chibi crossover spinoff basically takes all the main charactersfrom these various franchises and sends them to another world... again... where they meet each other in a seemingly ordinary human school and are forced to become students. Of course what the anime is actually about is simply putting all these loveable characters together just to see what the hell happens, and that is really the charm point of it all. Just seeing the crossover interactions play out is something any fan of these series should have a great deal of fun watching. After all, character relations such as Tanya's hatred for deities like Aqua and in turn Aqua's animosity towards the undead such as Ainz is unavoidably going to lead to a great deal of interesting confrontation.

It's a simple show by design but it definitely works. The only real problem with it is that there are so many characters involved and potential interactions that would have been fun to explore, but with only 9-minute episodes (excluding OP and ED duration) we only ever get a quite limited amount of exposure to a large portion of Isekai Quartet's character cast. There are so many things I would have liked to see the show touch upon that never ended up happening simply because it ran out of time. But nevertheless it is still a great spinoff which I would highly recommend any fans of the related series to watch. It may be short but it's exceptionally sweet.
