From all the yaoi manga that I've been reading recently, this is a real improvement. The art is incredible, stylized with a great character design. Story-wise it's average but I do like how some situations were handled. Risuto is part of a very powerful family. He inherit the ability to "charm" people so they made his will. Even if this sounds like a good thing for him, this arcane power gives him a lot of problems.
On the other side we have Luka, he has the same power but he knows how to use it better. From now on, there are gonna be spoilers.
I was a little wary about the main relationship but somehow the "we are demons" made it work for me. It's a justification for the insta-love and sounds plausible. Some very disturbing situations -sexual abuse, incest, bad moral behavior-, are condemned -unlike other yaoi books-. I was pleasantly surprised.
The cousin being a moderately nice human being was a high point too.
I wish the plot would revolve more around the "cursed blood" since at the end we found out some people were not affected.
To sum it up, I enjoy it, it's sexy, it has some drama, and even if sometimes it feels rushed, it's a well-rounded story.
