I really don't know about this series. Firstly, the characters just look too "pretty". I just find it hard to believe that the same studio that created Black Lagoon and Highschool of the Dead made this. It looks too "art house" anime and not as much a fun series to watch.
Then there is how they are showing the series. It's airing in Japan, but not on any of the major anime websites for the American audience to see the Japanese series, such as Crunchyroll. When it finally airs on TV, it's only going to be on G4TV. I'm sure tens of people will see it then. Why not also put it on HULU or other official sites that distribute anime legally?
