This is an interesting series. A post apocalyptic sci-fi story written and drawn by Chiba Toshirou. The world lies in ruin, most men are gone, and all that remains in the Lower World are beautiful women and ugly orcs. Though artificial men do descend from the Upper World from time to time, tasked with searching the past and providing for the future.
