Vincent Phantomhive was what they would call a devil in disguise, hiding his true nature behind a mask. By day, he was nothing more than a nobleman. A loving husband and a soon-to-be father. But by night, he became the Queen's guard dog, King of the Underworld. He was manipulative and cruel, killing mercilessly all those who stood in his way. He would stop at nothing to ensure the Queen's happiness, that the deed was done, no matter how dirty.
However, even the Queen's guard dog made mistakes. Making deals with those who were immune to his dark charm, unable to be manipulated to his will. Being manipulated himself, tricked into believing a string of lies perceived only to lead him away from the scent of his next victim. One wrong move, and everything fell apart. He would disappear for a few days to a week, being tortured for information. But never once did he let a single detail spill from his lips.
Despite it all, his loyalty never wavered. He remained the ever faithful guard dog, obeying every command given by it's master without hesitation. And that is how it will remain. As long as he is alive, he will forever be the Queen's guard dog, be-ridding of anyone who dares to defy Her Majesty. Just like a loyal dog, the loyal dog that he is.
