Set before the events of the 1st season, on the eve of the Russian Revolution, our favorite Chiropteran-hunting duo masquerades as members of Tsar Nicholas Romanov's royal chamber orchestra. Saya begins to uncover some of the strange secrets of the Romanov royal family and -- of course -- finds some hideous Chiropteran beasts that are doing a little masquerading of their own. Despite being one of the Chiropteran "originals," Saya's devoted her life to eradicating the wilder, more vicious Chiropteran spawn who prey on humanity.
