Human

Humans are mortal ones in the Twilight world. It is said that humans are often food to vampires that those who drink human blood. However, it is said that human blood vampires don't target on young ones that are handsome or beautiful since the Volturi made a law about that. They target on ones that are not to young. If any human knows the secret of every existence of vampires, then they must be turned into one. If any vampire in the Twilight world drinks animal blood, they don't kill humans at all since their hunting is mostly animal. When a human is often bitten and all the blood is devoured from a vampire, they are not turned into one. The only way to turn a human into a vampire is to bite and delivers venom to inject into the heart. Once the human is turned into a vampire, it has to choose it's path of drinking animal or human blood.
