First of all, let me state the obvious: this is not an independent anime, this is a crossover project with 4 different sources. So, to fully enjoy this title, you should watch at least some (preferably all) of the sources. And when it's done - you will appreciate this title fully, cause all the characters included behave exactly the way they did in original. Or, if you don't - you will miss 90% of humor, cause it is based on originals. Art style may put some people off, but it is the same exact style that was used in short comedy spinoffs, so no problems read more

This is a crossover combination of 4 anime (Overlord, Konosuba, Re:Zero & Youjo Senki), and if you've seen and/or love those anime, you will love this crossover! If you haven't seen those anime, please proceed to watch all of them and then watch this crossover in all its glory! No, but seriously if you haven't seen and/or didn't like those 4 anime, you'll have a very hard time appreciating this show.

An average Joe: “Avengers: Infinity War is the most ambitious crossover ever!”

Me, a cultured anime connoisseur: “Isekai Quartet says hold my out of this world sake!”

Isekai is one of the most hated anime genres of them all. Yet even so, there are a select few Isekai that are generally well received by the anime community for adding unique twists to the genre or by just being entertaining to watch. Four such Isekai anime have been brought together and chibified in order to create the awesomeness that is Isekai Quartet. And so far, it has been a pleasantly enjoyable watch.

Obviously, this is just a lighthearted comedy/parody read more

🔥 4 Isekai worlds being Isekai'd into another Isekai... and they said that Infinity War was the most ambitious crossover event in history

The anime itself currently presents itself as being quite capable with a good potential to become a funny series, all the most liked characters of each show featured in this show are given a good amount of screen-time right from the first episode and in the coming episodes. In other words, they did a great job at making each viewer of the show content with what they got. It doesn't matter if all you like is Overlord because you'll still love this show read more
