That was a very weird premise for the series, but so long as it can distract away from the fanservice, then it's fine. I must say though, for a show like this, they really rushed through a lot. It introduced numerous characters at blinding speed which comes at the detriment of our main protagonist. What a shame, he seems to be cool and mature, and I would like to know more about him. Anyways, the show is technically above average, slightly I think, more can be done in animations and audio, but they are fine as they are. I don't think I could give a verdict on first impressions, but if you like it, then watch. I am just curious how the story would progress from here on out.
