In occupied Japan in 1946, an American military investigator is sent to Yokohama Base to research a number of bizarre deaths. His encounters with a mysterious, sword-wielding stranger and a series of supernatural events lead him to believe that the murderer isn't human. Something more sinister lurks within the shadows! Paying homage to the previous Blood series - but telling a wholly new story - Blood-C: Demonic Moonlight is the prequel fans have been waiting for!
