Rosalie Anne Michaelis, a beautiful young demoness who is full of excitement. She has come across her much more mature, older brother, Sebastian Michaelis once again. It seems like any typical story right? Wrong, here's why. One day Ciel gets a rather odd letter from the queen stating that she has a surprise for his butler... what? It said to meet them at a train station at 3:00 sharp. Rosalie comes off the train and is almost too excited to meet him again, but what will happen to the earl and Sebastian? Will Sebastian pay more attention to his sister than his master? Will she persuade Sebastian to leave the manner for good?
