Just discovered it myself. It seems to have a bit of a Disgaea-style humor. The art is pretty good, and the manga is not as full of fan-service as say, To-LOVE-Ru. It also seems to know when to take itself seriously as well. However, it probably won't be until the manga and the scanlators reach volume 5 that we'll have an accurate estimate of this series' value.
It's funny that some people place it in the harem genre when, aside from the numerous females, there's been next to no instance of harem antics.
