(Y/N), a mere human came across the cunning demon Sebastian Michaelis. Sebastian has taken quite an interest to (Y/N) but will a demon and a human ever be together? DISCLAIMER: I do not own any characters, they all belong to their rightful owners.

Just sit back and watch the story unfold. The title pretty much explains it anyways. I DO NOT OWN BLACK BUTLER OR YOU ONLY THE PLOT!

I'm Zandra Michaelis. Yes, I'm the daughter of Sebastian Michaelis. I am 4,517 years old, but look around the age of 15 or 16. My father says I'm the split image of my mother, except with his red eyes. I have long navy blue hair and the same perfect figure of my mother. The only noticeable thing I gained from my father was his red eyes. My mother was a neko demon or more precisely a cat demon. No surprise there since father loves cats. She was murdered a few days after my birth by the hands of Claude Faustus, the demon butler of the Trancy manor, with the Sheathe of Lævateinn. The blade was taken by my father to kill Claude, but instead killed Hannah, the keeper of the blade, who jumped in the way for Claude to escape. That blade is now within me. So that makes me part neko demon and crow demon. My reflexes are more aware than my father's, my strength is doubled, and my speed is way more advanced than any normal neko or demon. The young master, otherwise known as Earl Ciel Phantomhive is 15. My father and I serve him everyday and help him on his 'missions' by the queen. The queen has ordered us to depart to Japan and help with the cases there, as she has plenty of others that are able to do cases in London. She also said that he should enroll in high school to affiliate with other rich companies to make the Funtom Company stronger. My father also wants me to enroll to be able to protect the young master from any nuisances. The school we're going to: Ouran Private Academy. • • • Rated mature for strong language.
