I don´t understand why it is so underrated. The series just tries to make fun of its own genre and it is just funny. It´s not suposed to be anything else. For anyone who didn´t watch it, if you like konosuba this is probably good for you. There is no depth and the anime doesn´t take anything seriously. But it is fun to watch and for me that is more than enough. I watched a shitload of anime this year and this really one of the best anime that came out 2021. If you want to watch something serious this will not be anything you like.
