6. It's historical fiction based on the Thirty Years War :P Yeah. It's really awesome, and Miura did a lot of research for it. Not only that, but half of the manga is based on Aristotle's writings and musings on a man-made Idea of Evil. The anime kind of deviates from the plot, but the manga has a lot of accuracy and good religious points and and and. It's got everything from weird incest kinks to homoeroticism to sexy love triangles and and and political intruige and..uh..lots of demons and gore. BUT OH WELL :D I love it. But damn I would NOT want to be a woman in that world. I don't think I'd be able to fight very well, which means I'd be screwed by either the plague or abuse, rofl.
