To start there is a lot of gratuitous fan service in this anime. That aside it is a very enjoyable show. Obviously from the ending they were hoping for a second season. It needs one please. I'm sure I'm not the only one who feels that way. I do not get technical about art, story, or sound. If I like the characters and enjoy the show, I consider it a good show. I liked this show and could not tell you why I just did. Itwas a simplistic premise. The harem was underdeveloped. The main is annoying. Despite all that I really enjoyed this show.
It fulfilled what I wanted it to do. It entertained me to the point that I stayed up till 2 on a work night to watch it in its entirety.(I get up at 6.)
In short if you are looking to be entertained this anime delivers. Nothing heavy to think about , nothing breathtaking to look at, just a good batch of entertainment.
