Legend of Duo

It is the early 21st century, and mankind is doomed. Due to a mysterious virus that steals the essence of human life, humanity has been pushed to the brink of extinction with only one hope for salvation: the blood of a vampire. Vampires have closely guarded the key to curing the virus for several years, which has led to an immense rift between them and humans and the world's descension into chaos. A vampire named Duo, having leaked the secret to saving humanity, is now considered a traitor to his race, and the powerful vampire Zieg is on his trail. However, due to Zieg's sense of duty, his heart is torn: should he kill the man who betrayed his people, or will his personal history with Duo sway him to have a change of heart? Each episode of Zelda followed the adventures of the hero Link and the royal Princess Zelda as they defended the kingdom of Hyrule from an evil wizard named Ganon. Most episodes consisted of Ganon (or his minions) either attempting to capture the Triforce of Wisdom from Zelda, kidnap Zelda herself, or use another method to conquer Hyrule. Link and Zelda are in some episodes assisted and accompanied by a fairy-princess, Sprite.
