Anno Dracula

"In 1899 Geneviève Dieudonné travels to Japan with a group of vampires exiled from Great Britain by Prince Dracula. They are allowed to settle in Yōkai Town, the district of Tokyo set aside for Japan's own vampires, an altogether strange and less human breed than the nosferatu of Europe. Yet it is not the sanctuary they had hoped for, as a vicious murderer sets vampire against vampire, and Yōkai Town is revealed to be more a prison than a refuge....

In an alternate history of the nineteenth century, Queen Victoria has married Vlad Tepes, better known as Count Dracula, leading to a reign of horror, while, in Whitechapel, Silver Knife, a murderer of vampire girls, threatens the new regime.
