Art was really well-done. It was a decidedly silly romp and I thoroughly enjoyed it. As far as story, it wasn't ground-breaking or anything, but sometimes it doesn't take a ground-breaking story for you to enjoy yourself. It's funny how despite all the blatant fan-service and ero, the manga still managed to make me feel a sense of child-like innocence. The ending was pretty much trash in a hole, though.
It's not bad. I actually liked it a bit. Interesting story idea, if a bit on the silly side. The artwork is pretty good too. Its main drawback is that it's not very coherent. It's more like a collection of one shots about the same characters.
