The Blood Contract (Ciel x OC x Sebastian)
I do not own Black butler or it's characters, all rights go to Yana Toboso. I only own some of the plot, and my OC's including Rozalina and her family.
Rozalina Ivanovna Dragomirova is the youngest child and only daughter of Ivan Viktorovich Dragomirov the Vampire King of Russia. Rozalina has grown up sheltered from human contact besides the occasional human pet her father would get for her to feed on and play with. She's young, for a vampire anyways, and she wants to explore the world and see new things, but her father won't allow it, he says it's too dangerous. In the 19th century Vampires are common and are rapidly being hunted and killed. Vampires are extremely feared during this time, but that doesn't stop Rozalina from stowing away on a ship headed for England once she finds out her father has planned to marry her off to some wealthy vampire prince from another country.
Upon arriving in England, Rozalina finds herself in London where she's forced to keep shelter from the harsh sunlight and only come out during the night. It's when she stumbles upon a Jack The Ripper crime scene after following the strong scent of fresh blood that she runs into a young boy and his strangely handsome butler. From the moment Rozalina laid eyes on the two she knew she'd found the adventure she was looking for.
