Despite completing all the tasks given to them, Ainz Ooal Gown, Tanya Degurechaff, Kazuma Satou, Subaru Natsuki, and the other members of Class 2 are surprised to find out that their role as students is far from over. With no means of returning home, the class of eccentric personalities is still mysteriously stuck in the unfamiliar world. Although, as they are becoming quite fond of each other, spending more time together does not sound that bad. With the unexpected arrival of new transfer students, the comedic antics of our beloved characters continue to grow. Thus, their bizarre yet nonchalant school life continues.
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. You can also free Isekai Quartet 2nd Season anime watch online and free download.
