The plot and story were your usual recycled harem deal, but this may sound silly, the main thing that I enjoyed about this show was the artwork. Great style and no dips in quality, A+ all the way. Also I was glad that unlike so many other animes, the girls were not stick figures. I get tired of seeing the characters looking so fragile that they might break if you touch them.
The only thing I guess I didnt like was that the story didnt progress much from the beginning to end. Not a big deal to me but may be for some.
