The typical perverted boy meets beautiful innocent girl but with a twist the girl is a robot! As much as I loved this anime the story really wasn't too original or inspiring. Many places where is is just a fan service but the detailed gothic lolita styled dresses give it an up in the art category.
As for the characters they are typical and not liable to change much throughout the series. The robot twist does add a little points in this category though.
The theme song and the two ending songs were wonderfully chosen and the voices where well done as well.
Watching it was pleasant because it was just a funny uplifting with some dark plot behind it. It was a nice little anime that really just kinda made your day and just asked you to keep watching it.
Overall I would have to give it an 8 because even though it is very good it really isn't near the best animes I have watched but still deserves to be mentioned because it is still really well done.
