I'd have to say that it's a relaxing anime to watch. The main story is just about a little princess finding the best way to sleep but the lack of story is made up with great art work and a wide range of different characters with their own personalities and that's why I think it's a really enjoyable series. While it's a comedy like series with a new story about sleep with each episode I think it's a great series but if there would to be a second season they would have to change things up a bit or else it may get bland.
