If you can get past the chibi art style and the fact this is a pure fanservice crossover series, there's a lot to enjoy here. Every character is written like themselves (and every VA has returned to reprise their role, both in the Japanese and English dub even). And it's just a lot of shenanigans of these characters being put into a school together. While it's definitely a comedy, it's also not too unserious. There's a grounding and developments between the characters and situation here that get fleshed out. This might not make it a laughs-per-minute type of show, but it does play into making
the characters more interesting to watch interact with one another. And since each of the four animes crossovered here have notable characters with big personalities, that's a good thing.
(small Season 2 update, a fifth show has been added into the cast in S2, Rising of the Shield Hero, but all the same points remain to its addition, the Shield Hero characters all have returning VAs and are written like themselves.)
Not everyone's going to like it; as this crossover is rather shameless it might make some roll their eyes at this, and if you happen to only like one or two of the shows and actively loathe the others you may not appreciate aspects of this show since it does a surprisingly good job at capturing the "downtime" atmosphere of each show in moments with it's characters (Konosuba's characters downtime moments feel like Konosuba, Overlord character downtime moments feel like Overlord, Re:zero and Tanya the same), and not all may appreciate seeing these aspects blend and play off one another. Like if you like Konosuba but hate Overlord for example, you may not appreciate Konosuba moments getting interrupted with an Overlord type scene, or even the two of them blending in some weird sorta' hodgepodge.
However, if you're a fan of most or all of these shows and their downtime moments and characters, there's a lot of fun in seeing them all interact and how they all weirdly work together. And even if you haven't seen all of them, this might be a good way to get interested in a few series (all four of which coincidentally are available on Crunchyroll at the time of writing), and the characters personalities are all established pretty solidly fairly quickly, so there may be enjoyment even for those not in the know-how. The Sgield Hero was kinda great. If you want to watch crossover anime, tgis is the place.
I watched this mainly out of curiousness at first, because I really enjoyed Shield Hero, so to see characters from that show pop up in this. I figured I'd give it a watch, and I've kept up ever since. Even went back to watch the first season. It's really fun and those 11mins go by way too fast for my tastes.
Story? There isn't a lot to say on the story given it's setting, and being that this is the second season. You're already in the loop of things. Not that it's bad, but more you're already know what to expect in some cases, but it
still goes along swimmingly and great. Which I'll explain by the way the characters are.
The characters are really hard not to like honestly. Whoever idea it was to put this together, knew what they were doing. The characters really shine once again through comedic moments, to sometimes wholesome. To the point I'm even going through their respective shows, as I haven't watched them before. They're really likeable in that sense.
The music is what you'd expect at a 'school anime' so there isn't really a lot to say there. It's nice and peaceful as you'd expect. It's art style is really nice also. Bright colours, and other colours to fit the right moments. Well done.
It's honestly really great. You should keep watching! Just as good as the first season is.
I believe if you are watching isekai quartet then you know what is happening. If not here is the basic plot: Some character from KonoSuba, Youjo Senki, Re:Zero and Overlord are put into a school setting and we just follow their daily lives in school. Now in the second season we got characters from Rise of the Shield Hero, who barely is even in this show. Naofumi appeared like once during the first episode and the entire 2nd episode was focused on Naofumi, Raphtalia and Filo but after that they haven't been seen since. Entire 2nd season has been just bullying Aqua.
In every episode at least 2 people bully her. The opening and ending are worse than the first seasons but they are still very good.
Characters: If you have watched the previous season and the originals shows which you should watch before starting this show since everything makes more sense after that, I dropped the show once since I hadn't seen Youjo Senki. The characters do act a bit differently from their usual self but not in a huge way. The character power balance is fucked or at least Ainz said so.
If you have seen all the shows and I do recommend that you watch them since all of them are good, and of course have seen the previous season then this is also a good watch.
