Plot
In 1923, the Japanese government creates a new unit ("Code Zero") within the army to counter the rising threat of vampires, as well as their artificial blood source. Code Zero offers all vampires the same choice: surrender and receive benefits such as blood and formal registration, or face eradication. The vampires themselves defy classification, exhibiting a great deal of variation among their ranks and little loyalty towards each other. Though all were once human, most people who are bitten die immediately. Those who become common vamps are simply staggering, mindless predators, while "noble" vampires are far more intelligent and refined (though no less cruel). Still others are able to hold on to their human natures and long for a sense of belonging in an increasingly hostile world. As the members of Code Zero carry out their mission, they encounter strange vampires, humans, and phenomena that force them to question their own identities and purpose.Characters
