There is are no real characters to speak about. In addition, there is no story. Character development consists of a dancing blob. The dancing doesn't improve, so I guess there isn't any development. The blob doesn't learn from past mistakes, not exactly well-rounded.
Enjoyment? None. I'd rather watch Nami on repeat with my eyes held open by paperclips.
Overall, I suggest you avoid this anime. You will not get back these 30 seconds of your life. Why waste it on something so tragic?
