I hadn't seen an anime as loaded with fanservice and ecchiness like this one in a long time! Basically, all female characters (95% of the complete series) end up nude at some point, revealing their breasts and butts, in awkward positions. If you like these types of things, you'll be very grateful towards this 3-episodes OVA.
The story is very silly, light, and pointless. Art style is good, better than many other similar animes, and they focused a lot in the depiction of the female body. Sound is fine; the voice acting seemed to be alright for the most part, and I can't recall at all the opening and ending songs (that's how good they were). Character development is very vague for most of them. The main 3 characters, however, are explained enough as for the viewer to understand them.
Overall, I enjoyed the anime. It delivered a lot of fanservice, which I must admit I like, and it got me entertained.
