Honestly I started watching this anime because I thought it was somehow related to Akame Ga Kill (one of the best animes I have ever seen) but when I started watching I just fell in love with the art style. I was hooked because of the art style but I continued watching it because of the amazingly entertaining story. There is never a time where you are not engaged in the story. If there is not any action in an episode you can be sure that episode you are going to laugh your ass out. The soundtrack is one of the best I have ever heard since I watched Naruto.
Honestly this is a great anime that you should definitely watch
