Vampire

Vampires are the supernatural creatures of the Vampire Knight universe. As in traditional folklore, they are sensitive to the sun and are active during the night; however, in reality, sunlight only hurts their eyes and does not actually casue them any damage.

When killed, vampires will turn into dust, though Purebloods are an exception in that when they die, they shatter into shards of glass instead. The most effective way to kill any vampire is to cut off their head or stab their heart using an anti-vampire weapon. Blood tablets had been developed to take the place of actual blood feeding, despite having a bad taste. Vampires also have a bloodlust that can only be quenched by the blood of their beloved.

History
Vampires have existed for well over 10,000 years, first appearing when mankind's civilizations began to crumble. At one point, they waged a war against humans, during which Purebloods began turning humans into vampires. When the number of vampires began to increase, a monarchy was established to rule the vampire race, with the Kurans as the royal family.

However, two generations ago in current times, the former king and head of the Kuran family (Rido, Haruka and Juri's father) abolished the monarchy in order to avoid authoritarianism. The Senate was then established to govern the vampire realm, with high-ranking vampires aristocrats in the seats. Despite their demoted status, however, the Kurans still hold the title as the highest standing family, and it is well known there are many vampires families who would support Kaname Kuran if he should chose to take back the kingship.

Classes
There are 5 types of vampires, ranked according to the purity of their blood. The more diluted by human blood, the lower their ranking is.

Level A is the Purebloods, the rarest, most elite, and most powerful class, whose blood lines have never mixed with any humans. Purebloods are also the only class that can turn a human into a vampire.

Level B are known as "Nobles" or "Aristocrats". These are also very powerful vampires, but not as mighty as Purebloods. They have a small amount of human blood in their ancestry.

Levels C, D and E include humans who have been turned by a Pureblood rather than being born as vampires. These ex-humans would eventually go mad with bloodlust and become a "Level E" if they are not stabilized by drinking the blood of the one who originally bit them. Stabilized ex-humans are known as "Level C" or "regular vampires", and humans that have been bitten but have not gone mad are "Level D".

Purebloods
Level A Vampires. The heritage of these vampires hasn't been diluted by human blood. They are the strongest type of vampire and have the most significant powers, and can destroy any lower vampire with ease. However, despite the fact Purebloods are very powerful, they make up for it due making up only a very small portion of the vampire population. The Senate holds Purebloods in extremely high regard, to the point where it is taboo to kill or even harm a Pureblood. As a result, they are treated like royalty. The powers of Purebloods are dangerous to both their fellow vampires and humans. Purebloods have the ability to compel lesser vampires to do their bidding. In recent chapters, Kaname Kuran demonstrated why Purebloods are feared and respected by single-handedly killing the members of the Vampire Council. If a human is bitten by a Pureblood, that human will turn into a vampire. The Pureblood and ex-human in question have become bonded as Master and Servant. The master is able to completely control their servant, while the servant becomes incapable of ever killing their master, even if they wish to. When Purebloods die, their bodies slowly disperse into small sparkles (as shown by Shizuka Hio's death in the anime) and then shatter like glass.

Aristocrats
Also known as level B vampires, they are elite vampires with specialized abilities beyond normal vampires.These are also very powerful vampires, but not as much so as Purebloods, due to having a small amount of human blood in their ancestry. They have super strength and speed, as well as specialized powers such as mind control or freezing matter. When an aristocrat is killed, they turn to dust like all other vampires except for Purebloods. These aristocratic vampires are still able to be compelled by Purebloods, but enjoy a much more independent lifestyle in general. The Council of Elders is usually made up from their ranks.

Commons
Level C vampires. These are average vampires with no significant powers. Level C vampires are not usually seen in the anime but have several different appearances throughout the manga. They only have super speed and they heal faster than a normal human.

Ex-humans
Ex-human vampires, also known as level D and level E, are the lowest form of vampires, humans who have been turned into vampires by being bitten by a Pureblood vampire. The E in Level E represents the word 'end' because after falling to level E, it's usually the end of their life after losing control. If they don't want to die, they'll have to drink the blood of the Pureblood that bit them. The consequence is that the Pureblood would have complete control over the person and that person would truly become a vampire.

Powers
Elite vampires, such as Level B and Purebloods are known to have special powers. The following powers have been demonstrated:


 * All vampires display an accelerated healing. The purer the vampire blood, the stronger the healing factor.
 * Decelerated aging: the purer the vampire blood, the longer the life of the vampire. Purebloods are immortal. They age very slowly and they can only be killed if someone cuts off their head or if they are continously imbolised and shot/stabbed in the heart with an anti-vampire weapon.
 * Ability to erase memories.
 * Ability to use animals as a familiar, to watch and listen.
 * Telekinetic powers, ability to use these highly destructively.
 * Arisocrats most commonly display the ability to control an individual element, such as fire, ice, lightning, etc.
 * All vampires hace hightned senses like their ability to smell blood from a great distance.
 * Super strength, vampires can tear through flesh with ease and destroy large concrete structures (walls,pillars,etc) and can leap great distances
 * All vampires have accelerated speed, they are able to appear beside someone instantly.
