Her father holds the key to Japan's bloodshed. She must find him. Chizuru Yukimura is on a mission to find her father, after having heard no word from him for over a month. After unwittingly becoming both a victim and a witness to a crime when she travels to Kyoto, Chizuru falls into the hands of the Shinsengumi, the Emperor's special police force. Just like her, they are after her father as well but their intentions are far more serious. It appears the Shinsengumi are hiding something deadly from the public. Known as Furies, they are vampire-like creatures of their own making in their pursuit of the ultimate enhancing drug. But the Furies maybe the least of their worries when Chizuru's family may hold a deadlier secret, that can ultimately change the course of Japan's future.
