Just a grat manga overall, from the characters to the story itself. Even though it has a dark and mature main theme, it also can be comedic and light at times; especially with the Dance with the Vampire Maid chapters thrown in. I was however upset for a split second with the ending because it was a cliffhanger making me want to know what happens with Akira, Yuki, and Mina; but then I found the sequel Scarlet Order (which I am currently finishing up). This is also one of the original mangas that got me into reading mangas back when I was a teenager; and even though this manga has been around since 2005/2006, the story, art, and just everything about it makes this manga stand above most manga (in my opinion) even today. Definitly worth a read, will not be disappointed.
