^It's interesting how different artists can give the same storyline completely different impressions. The demon queen in the version above looks more like a holy priestess (...with horns!), while the one in the scanlated version has more of an I'm-smart-and-I-know-it impression.
I lol'd at the first chapter though. Our poor hero didn't stand a chance. She's got the arguments, she's got the data, she's got the, ah, "looks," and she's got that totally unfair upward glance and pout which no man can withstand (a real life oft-used weapon, to be fair).
