It is a run of the mill OP main character isekai that is as deep as a puddle of water in the road. Nothing new is added to the formula but that doesn't have to make it less enjoyable. Art: The CGI is atrocious but the rest of the art is decent. Story: It is simple and predictable. MC is a loser, something happens, MC gets overpowered as hell, and good looking of course. Music: Nothing special. It works for the anime. If you're looking for a anime to just watch and shut-off your brain to it sure does the job. For that simple reason it is enjoyable.
