The execution and enjoyability of this series reminds me of Prison School. It's somehow an anime for grown ups, even if it's no sex involved.
The characters are well done, even if their screen time is just too little to develop them. The only character with loads of screen time that doesn't evolve is Sakamoto, but that is because of the nature of the character in itself.
This is one of those animes that needs to be tasted by yourself before deciding to watch it or not. It's one of those animes that either you love it or you don't understand it, so go see it for yourself.
