I'll just start making clear that it is a comedy. So... don't expect great stories, but fun and silly ones. In my opinion the best part is the art. A lot of light, very easy to see. All with that summer vibe. The next big point would be in my opinion the characters. They all are funny. The sound is maybe too crazy for my taste, but it is fair with the anime vibe. And finally the story... it is very short, and with no much relation between episodes.As a result is a short anime, that you can enjoy when you want, almost in any order.
But the most important thing of all: it will make you smile.
I really enjoyed levia-san, muromi and her phobias, the fish, and the boy dealing with all that mermaid craziness.

In my opinion is a dark horse from the spring'13 season, I give it an 8
