Ceil and Alois aren't the only ones with a demon as their butler. What happens when a young sociopath girl is the Queens Cobra. Also know as the witch's snake.

You, [Name] [Last Name], are the best young assassin in London. That's the reason you were chosen, well, blackmailed, to kill the Queen and her only son. But you nearly got caught, and you'll now have to disguise yourself as the queen. Your life depends on it.

Everyone knows who the Queen's guard dog is: Ciel Phantomhive. What happens when the Queen finds another pet, this time a sly kitty with her unearthly butler, and decides to make a team of the two? Excerpt from Chapter One: "Lady Maria Elrose, also known as the Queen's kitten." The butler's eyes widened a little bit before he was rudely shoved aside by a smaller boy with an eyepatch and one blue eye that was visible. "She's a girl?! An actual girl?!" He looked her over, his shock momentarily showing. "You are the Queen's dog, are you not," Maria replied. "I do not believe you are an actual dog either." Ciel looked long and hard at her, realizing that she wasn't just some ditzy - animal - pet of the Queen. ----------------------------------- Excerpt from Chapter 10: Sebastian slowly shook his head, and Ciel closed his eyes and leaned back in his chair, his untouched tea sitting on the table before him. Anyone - human or demon - could literally see the worry rolling off of him in waves. Sebastian himself felt a twinge of... something. "I will find her, my Lord." He bowed deeply as Ciel responded. "You had better, I ordered you to."
