Ex-Human Vampire

An Ex-Human (元人間, moto-ningen) is a type of vampire who used to be human. They are Level D (Dクラス, D Kurasu, lit. "D Class") and Level E (レベルE, Rebere E) vampires.

When a human is bitten by a Pureblood vampire, they will either die from blood loss or poisoning, or they will suffer the slow agony of the awakening to become a vampire. These vampires are easily controlled by their master and are unable to kill their creator. One of the few advantages is that unlike normal vampires, they are not overly sensitive to sunlight.

When Hunters capture level D vampires, they tattoo them with their symbol and perform a "taming" ceremony enabling them to disable a vampire with a linked piece of jewelry. While the hunters have a ward to prevent vampires from entering their buildings, an exception is made for tamed vampires.

Eventually, every ex-human vampire falls to level E, and loses his or her humanity and goes mad with bloodlust. These vampires are then put on the list for extermination. However, they can be saved from this fate if the Pureblood that created them gives them their blood.

Trivia

 * The transformation into a vampire is not instant, though once bitten the human will become subsevient to the Pureblood that bit them.
 * As shown with Zero, a Level D can be prevented from falling to Level E if they feed on blood on a regular basis.
 * Level Es could be divided into two categories: those that went mad from suppressing their bloodlust and those who freely feed on humans and thus are a threat.
 * Ex-human vampires (if saved from turning Level E) will cease aging once they reach their prime as neither Seiren or Zero look any older 50 years later.
