Legend of Duo

Early in the twenty-first century, humanity is doomed. The only thing that can save humanity from extinction is the blood of a vampire because of a mystery virus that steals the essence of human existence. For many years, vampires have kept the cure for the virus a well guarded secret, which has caused a huge breach between them and humanity and the world's descent into anarchy. A vampire by the name of Duo is now being hunted by the ruthless vampire Zieg for betraying his race by disclosing the key to saving humanity. Zieg, however, is conflicted because of his feeling of duty: should he kill the man who betrayed his people, or will his past experiences with Duo cause him to reconsider?
