There was only one thing you need to know that was wrong about this anime... It doesnt have a season 2. It should literally be criminal for this to not get a season 2 and I dont understand.
Overall, however, the show was great. Its comedy was top notch especially for a high school boy like me. One problem I have though, other than how short of it was, is how one of the MC's, Tadakuni, didnt appear as often as I hope he would. If you are looking for a comedy, this is a seriously good pick to watch.
My favorite part of this anime has to involve a running gag that happens on a riverbank. Thats all I can say without spoiling it.
Seriously go watch this.
