Isekai Quartet

I have loved Konosuba, Overlord, Tanya the evil, and Re: Zero and there takes on the isekai genre. most of them got me hooked onto that genre when looking for manga but hey not everyone is going to like this and that's okay. But I can say that if you are a fan of any of these series then you'll have a good time.

Really good crossover anime but here are some people i want in it Rimuru: that time i got turned into a slime Satou: Death march to the parallel world Touya: in another world with my smartphone Hajime: from common place to world strongest And Takuma(Diablo): how not to summon a demon lord

The anime is in chibi style and the story is nonsense, but that's why I love it. A school story that brings together 4 different animes. And the ost is amazing too, just too good. I highly recommend watching all 4 animes as they are some of the best ones and you can also understand better the jokes.

Actually stopped 2 episodes in because the characters were amusing enough I figured the shows at the core of each of the group of "students" was worth checking out

This is a gem of an anime crossover, but it really requires the viewer to have seen at least some of the origin anime series to truly appreciate it. There are lots of insider jokes and references and if you haven't seen any of the origin animes, you'll probably won't enjoy it as much.
