It is a normal day; everyone from deranged military girl Tanya Degurechaff and 16-year-old isekai protagonist Satou Kazuma to expansionist overlord Ainz Ooal Gown and demon sisters Rem and Ram go on with their daily lives. Suddenly, a conspicuous red button begging to be pressed appears before them. Overcome by curiosity, the otherworldly characters push the button, sending them to an unfamiliar world.

With no way of escaping, the characters must lead a normal school life and make acquaintances with the others. One thing is certain: the classroom full of fan-favorite eccentric personalities never gets boring!

Who could’ve ever thought we’d get a deformed, chibi version anime from some of Kadokawa’s most popular works? At first, I thought the announcement of the anime was a joke until I saw the actual trailers and promotional images. Taking a look back, I also remember when Overlord and Youjo Senki had their own version of chibi shorts featuring goofball characters doing what goofballs what do. Maybe they were experiments to prepare for this anime. Who knows?

Without a shadow of a doubt, Isekai Quartet is based on characters from isekai shows. The character roster consists of the cast from KonoSuba, Overlord, Youjo Senki, and read more

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 characters read more

Trash mixed with garbage, fused with dog farts, and interwoven with mindless stupidity.

As a word of caution, I have not seen KonoSuba, Overlord, Re:Zero − Starting Life in Another World, or The Saga of Tanya the Evil.--Thus, my perspective is drastically different than a consumer who has seen these Kadokawa Corporation productions. With that said, however, Isekai Quartet is bottom of the barrel entertainment. Perpetuating the stereotype of puerile-based Japanese comedy.

As a word of caution, Isekai Quartet is a perplexing show. I understand it’s a comedy/parody of the Isekai genre, but the abysmal execution leaves me questioning the effort of the so-called read more

FINALLY, ABOUT TIME. The outlandish short comedy that is this show.

The biggest crossover not just in anime history, but one that can be said to level off with Avengers: Infinity War (no pun intended): Isekai Quartet, the short crossover that we knew we wanted for a long time, and thanks to the people over at Kadokawa green-lighting this high-profile series, we finally can rest at ease.

For the Average Joe, Isekai Quartet combines the Isekai universe's 4 most beloved series: Re:Zero, Youjo Senki (Saga of Tanya the Evil), KonoSuba and Overlord. And combine them Kadokawa did, for a collaboration that's unthinkable at this high scale, difficult read more
