Assassin? [Black Butler x reader]

Y/N, after the tragic murder of her family at only the young age of six, somehow manages to survive. Helpless, weary and half-starved, she wandered the streets of London, and somehow managed to stumble upon an odd man who was.. Oh, good lord, he was hovering above a corpse!

"The Striker", the most feared man in all of England and the best murderer of his time, originally kidnapped poor little Y/N, but after some time, became sort of a father-figure for the girl. He trained her in the art of murder, and taught her how to harden her heart. However, the striker had another special thing besides him just being extremely good at what he did. He only killed noblemen. Dirty, filthy rich people who abused their power. And so the two became sort of like Robin Hood together, killing the rich and avenging the poor.

When Y/N turns fourteen she leaves her adopted father and goes off on her own. After a couple of months, she gets herself in the newspaper. They call her "the Mistress", for she lures in unsuspecting, greedy nobles into her trap, with her charms, sweet words and caring facade, before getting them alone and slitting their throat. Easy and quick, no torture needed.

However, when Y/N decides to target the famous Phantomhive earl himself, she makes one fatal mistake... She has her first ever slip up, and gets caught! Will her turn her in? Or maybe he'll end her himself: he IS the queen's guard dog, after all.

So what next?
