Whilte reading this manga, I wasn't sure at first how I would like it, even though my tastes are all over the spectrum. In the beginning, the translations were difficult to follow while LOLScans was the main group working on it, however after chapter 28 someone else takes over, though I don't know who it is. They're scans were much better quality, and it was then easier to understand what was going on.
I sincerely liked the different concept of devils/vampires in this manga, I liked how much the author was trying persaude the reader that no two people are entirely different, it's like a lesson in not judging a book by it's cover, or in the case what you look like.
I rated the story 10/10, because it is beautifully written and sucks the reader in easily, even after just a few chapters. I couldn't stop reading for a few days, when I finally reached the latest chapter that was out, I was disappointed that there was no more available for public access (though ComiXology has up to 61 chapters available with purchase). Usually I dream about the content and come up with my own versions if I am left unsatisfied, that did not happen with this manga, which made me very happy.
I rated 10/10 for the art because this style is unique, Ryo Hanada's style expressed the characters emotions expertly, which causes you to fall in love with them or hate them, depending on your views.
The characters were rated 10/10 because, again, Ryo Hanada's development of them was simply awesome, the way they progressed, struggled, were careless, were caring, were brave, it was all very human of them and very in depth. I found myself liking several characters by the time I reached chapter 52, and not disliking quite as many as before. Though, I still firmly dislike a few, just because I find their personalities annoyingly written, as they remind me of real life people that I personally know.
I am glad I found this little gem, I hope to one day purchase the translated books one day, when I can.
Overall I gave this 10/10, if I could I would go so far as to give it 30/10.
I feel the genre is incorrect though. It feels more like a pyschological drama to me, than dark fantasy.
