I really did not read this one because I had already watched the Anime about it. I gave it a five star because I already know the story is good. Also, the sexy demon tag I gave it is just that. While the demon is playing as the young masters butler, he is fine as hell. Then you add the voice they gave him in the anime, it sent chills down my spine in a good way. ;-)
And after reading some of the comments on this one, I just might read it anyway since it seems there is more too it then I realized. :-)
