This show doesn't know what kind of show it wants to be so it left it so that it could be any kind of show. You find out that it is an isekai and that the entire class was transported, but you dont see the actual isekai event. It is like playing an rpg where someone else has played the first few levels for you and you are just continuing from there.
Story is horribly done including the attempts at comedy and fanservice.
The art is below average.
The characters don't feel unique. Especially the main characters.
The best way that I can describe this anime is that someone is trying to take their favorite parts of all the anime they have watched and put it all together, but they also missed several details
This is an isekai that is so poorly done that I created an account to leave this review so that others don't waste their time.
