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 ...

Mixed Feelings
I mean it'd probably be easiest for me to put some kind of Avengers joke here for the intro, but I'm pretty sure that's been done to death by this point, so I'll just go onto the meat of the review.


Alright, so let's give the main cast of Konosuba, Overlord, Youjo Senki, and Re:Zero a random button that just magically appears on their respective doorsteps in order to Isekai them again into a world where now they're forced to participate in high school activities and shenanigans.  What fantasy!  What merriment!  I bet the rights holders were high-fiving each other when they came up with this ...

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 ...
