I can't actually remember ever seeing a graphic novel with this kind of cover. Yaoi can possibly have scantily clad guys in compromising positions on the cover, but not quite like this actually, even if that's how they end up in the pages. And for a woman to get this kind of position? No boob, hip or neck exposure and with a serious, dark expression... also notice her lips being closed, while the dude (you might not see this because it's so small) has his scandalously slightly open.
Looking closely also made me notice other things. Like that her blade-tentacle-censor thingy is drawn as if it's hands grabbing her boobs. And I have no idea what the snake has to do with anything. The dude (whose name is Darkness) actually doesn't have *that* crazy shoulders to be a comic book dude. Lately I've realized that to make men look even impossibly more buff, they draw their heads smaller relative to their bodies which, when you start thinking about it, makes them look more silly than cool actually - just like I think Witchblade and all her boob-job friends look silly. I'm not saying all artists draw either gender that way however, there are plenty doing a fine job of applying cool comic style without drinking too deep from the more-is-better-fountain and falling off the tower of exaggeration in their drunken stupor.
