This review accounts for all 3 seasons. Let me preface by saying that this is the most underrated show I have ever watched. And by underrated I mean that more people should see this show. I started this show thinking it to be some weird niche show that only had humor going for it, and a story primarily episodic in nature. Boy was I wrong.The story and art are wonderful as long as you can deal with the occasional goofiness.
This show is incredibly unique and I'd highly recommend it if you're sick of the usual generic style of anime character, art, or story.
