One of simply the best mangas , i have ever read period! I haven't seen the Anime ( which i have heard isn't too great ) but the mnaga is a true masterpiece. There is not one department , that it doesn't deserve top marks. The art is amazing , the characters and story sublime , a gripping and intellect plot that's just polish its all round brilliance. I actually don't like horror storiestoo much ( the exception perhaps being Dance in the vampire Bund) but this was actually a story that transcends the the limitations of any signal genre , with its beauty and style.

All Ii can say , with out spoiling anything , is that if by the last chapter , your not begging for more , i would be very surprised.
