Sirius

In Tokyo in 1930, mysterious killings increase as vampires infiltrate the city. To hunt them, the Jaegers arrive: vampire killers who conceal weapons inside musical instrument cases and meet their prey with the same ruthlessness the vampires show humans.

The group's most dangerous fighter is Yuliy, a young man with werewolf blood and the sole survivor of a village destroyed by vampires. His work in Tokyo appears driven by revenge, but the deeper conflict centers on the Ark of Sirius, an artifact connected to his people with the power to alter the fate of the world. Between hunting vampires and uncovering what happened to his family, Yuliy must reach the legacy of Sirius before his enemies turn it into a weapon that cannot be stopped.
