Story was enjoyable, as well as most of the characters (and their designs). Characters weren't overly annoying. A bit too much fanservice though, that makes it kind of awkward to watch.
Music wasn't anything special, and the opening/ending themes didn't seem to catch my attention much.
Overall, I was surprised that I enjoyed a series with so much fanservice, but I think what won me over was everything else - the story, the art, the characters.
