This was entertaining, but not very deep. The premise of a future society with toxic air and bioconstructed cities is a good one. However, the stories in the volume are somewhat inconsistent in terms of the plotting. And yet, Shirow makes good use of some dark humor to balance things out, which makes the reader appreciate the work some more. The art is ok, but I think Shirow has done better in other works. I liked the catgirl molls. Overall, this is a pretty quick easy read. Casual readers may not appreciate it as much, but I think Shirow fans will like it. I saw another reviewer describe this as campy, and I think that is a word that applies very well to this volume.
