Though I only own one volume, I've read most of the series, so I have a good feel for it. The artwork reminds me of Battle Angel Alita with the general atmosphere it exhibits. The storyline itself is pretty goofy at first, but eventually it starts to get more serious as the volumes progress. Even then, the story never loses its comic appeal and has enough fan-service to choke a horse... twice. So if you like animal-people, random violence, and boobies, then Hyper Police is the manga for you... as long as you don't mind the rough artwork
