I liked how the manipulated all this myths and legends to fit the story. They really made them look quite different from what I imagined. Of course, it has something to do with anime's superficial nature. Some of the creatures they mentioned I never expected to have human form, and if they did most stories always add that they were but deformed representations of what they once were.
The music was cool. I really liked listening to it, but like any theme music, after watching a show continuously you sort of grow bored of it.
Again, I must bring up the point of it only had 12 episodes. For this reason I understand that the characters weren't meant to have really changed. It's not a fault, because they really handled it quite nicely. The characters were three dimensional, even though they didn't changed. It's not as if they had some stagnant personality. You see a couple sides of them as the series progresses.
Over all it was short and simple and cute, and I think that made all the difference.
