from back of bk: The prequel to the Blood-C saga! In occupied Japan in 1946, an American military inestigator 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! This two-volume series pays homage to the previous Blood series while telling a whole new story! A collaboration between Ryo Haduki & Production I.G - the studio behind Blood: The ast Vampire and the Blood+ series - this expansion on the Blood-C anime series is not to be missed.
I watched the anime some time ago, so there should be more chapters than this.
I didn't too much like the anime, but I would prefer the anime than the manga at the moment. Of course by watching the movie, "Blood-C: The Last Dark," made up for what lacked within the series.
