Anime franchise crossovers aren’t entirely unknown; see 2015’s Infini-T Force for a recent example. However, this 12-minute series easily surpasses its predecessors as possibly the most ambitious anime crossover ever, as it takes four of the most popular isekai franchises of the past few years and combines not just their protagonists but the entire core casts of all four series into one grand chibi-fied affair. That’s probably because the source novels for all four titles are published by the same company (Kadokawa), but even so, the sheer audacity of this stunt is staggering.
It’s also a brilliant conceptual move. Director/writer Minoru Ashina has essentially pulled the ultimate “meta” play by creating an isekai story about isekai stories, where characters who have been transported to another world are transported to yet another world. Just as amazingly, it looks like this wacky idea is going to work out. The first episode shows how three of the four groups feel about ending up in this situation; Tanya sees this as a stunt by Being X, for instance. The episode also allows characters from each series to demonstrate their viewpoints and idiosyncrasies; Ains plays the cautious info-gathering game but also quickly evaluates the KONOSUBA lot as having inferior equipment; Kazuma and crew debate whether or not they should attack the obvious monsters in the Overlord crew; Emilia sees the whole situation as a chance to make a bunch of new friends, and so forth. There’s also a small underlying mystery afoot in why the generals from Saga of Tanya the Evil seem to know what’s going on while playing the teacher roles, but the episode ends before they get to detail their circumstances.
Frankly, the reasoning behind all of this doesn’t matter much. The concept and casts present are absolutely loaded with potential for all kinds of fun interactions as different backgrounds and perspectives clash, and the chibi-fied designs and simple animation go a long way toward keeping things refreshingly goofy. If the creative staff can maintain a balance that keeps everyone involved in the chaos that’s certain to ensue, then this could be one of the most entertaining anime romps in a long time. It sounds like they’ve even brought back the full voice casts for each series too. The one catch is that it looks like you’ll have to be more than passingly familiar with all four franchises to fully appreciate the show; the Overlord parts reference events from the third anime season, and all of the Re:Zero anime has to be seen to fully understand what those characters are talking about. As someone who’s done episode reviews for all four franchises, this series is a dream come true.

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 Re:Zero. Collectively, they are united as a quartet of characters in a school life setting where all sorts of shenanigans blooms. As someone who is familiar with all of those established franchises, I do recommend watching them before stepping foot into this. Character personalities carries over and in general, I do believe you can get a better experience if you knew who the characters are. But for popcorn entertainment sakes, you can also just dive right into this little gem.
Even as a crossover, Isekai Quartet stands out as a show of its own. The episodes contains skit stories that are half length. Its main purpose is to humor with the immense amount of comedy that aims to draw our attention. If someone told me this whole idea sounded absurd, I might have agreed at first. That is, I tasted what Isekai Quartet really is and it’s pretty damn delicious. That’s thanks to the drama within that showcases this like a Saturday morning cartoon. To start off, we have several foil characters which translates into some rather noticeable character drama segments. There’s Tanya and Ainz who were once a salaryman in the real world. These two are portrayed as powerful entities that others seems to fear in from their perspective shows. In Isekai Quartet, there’s a rivalry that develops between the two based on some rather absurd reasons. KonoSuba’s Kazuma and Re:Zero’s Subaru came from fantasy worlds as the two manages to establish themselves in their own ways. However, it is easily noticeable how different both characters are. Kazuma is portrayed more as a butt monkey while Subaru evolved as a dark fantasy hero. When you put all four of these protagonists together in the same show, hell breaks loose. I’m talking about the over the top comedy type of hell of course.
With the school setting, the creators aimed to bring as many as possible segments as possible. From school rules to a class talent show, there’s many opportunities for comedy. (yes, there is the infamous “beach episode” too before you ask) Anyone who is familiar with these franchises will also quickly recognize how much their personalities carry over. Make no mistake, every character remains who they are from their respective shows. This includes Overlord’s core characters such as Albedo, Shalltear, and Demiurge. KonoSuba has its own class clowns like Aqua, Megumin, and Darkness. Re:Zero’s Emilia, Rem, Ram, and Beatrice are no strangers when they sit in class. And who can forget Youjo Senki’s adorable Visha? Bringing this legion of isekai characters also means a clash of personalities. Just like at school, there are class leaders and rules. The show establishes the rules early on and as each episode progresses, it becomes more and more evident how some characters can’t follow them. The class talent shows also displays a clash of egos. At the end of the day, the audience is the real winner as the anime accomplishes its job of glorfying popcorn entertainment. In a sense, this is a deconstruction of isekai. Character behaviors are observed in the some of the most outrageous ways possible. KonoSuba’s cast is the guiltiest of this with Kazuma’s antics, Megumin’s explosive personality, and Darkness’ perverted fantasies. However, others such as Albedo, Shaltear, and Beatrice also act on actions that speaks louder than words. My only slight disappointment is how much Tanya has to carry her own franchise in this crossover. Honestly, she is probably the most credible member from Youjo Senki. Even someone like Visha feels like she’s the invisible kid in class if you don’t pay too much attention. Similarly, most of the supporting characters from these perspective franchises is overshadowed by the main cast.
Isekai Quartet ended up being an anime that I didn’t know I wanted. When it got first announced, I thought this would’ve ended up being a big fat joke to further alienate the isekai fan base. It seemed like a big risk considering how much controversy their franchises became for certain audiences. But after watching this show to finish, I’ve seen the light. Be prepared to be enlightened.
