They have a small amount of human blood in their ancestry as well as all other levels below them. When an aristocrat is killed, they turn to dust, as do all the other levels below them.

Pure Bloods 

Purebloods (純血種, Junketsushu) are the highest rank among classed as Level A (Aクラス, A Kurasu, lit. "A Class"). They are "pure" vampires without any human ancestry, and can trace their lineage back to the .

Purebloods all possess a series of unique powers, often exclusive only to the certain Pureblood or Pureblood family.

There are currently only seven Pureblood families: , ,, Toma, Shirabuki, Ouri, and Shoto

A very long time ago, when the human race was on the verge of extinction the first vampires emerged. These first vampires, known as Purebloods, appeared. Purebloods are those who have not bred with humans, thus keeping their vampire blood pure. Some Purebloods breed with Humans producing weaker vampires which have came to be known as the Noble vampires. Most vampires have some human blood in them, but a Pureblood vampire does not. Purebloods, like all vampires are sensitive to the sun as it only hurts their eyes and can get sunburned easily.

War broke out between the Purebloods and the Humans at some point a long time ago. In order to defend themselves against vampires, some humans ate an ancestor's flesh, creating the vampire hunters which granted them the power and strength to kill vampires. This includes anti-vampire magic and weapons. Therefore all vampire hunters have vampire blood in them but not to the extent that they are classified as vampires, thus they do not benefit from a vampires longevity and thirst for blood. The vampire hunters protect the Human race from the vampires.

During the war, the Pureblood population greatly diminished. Many Purebloods drank the blood of humans during this time thus creating Level E vampires to increase the vampire population. Consequently, there are few Purebloods today.

The full extent of their powers are only known amongst their Pureblood companions. Their true powers remain a mystery. They have ethereal beauty of the Purebloods. They are immortal, meaning they live forever unless an anti-vampire weapon is used to cut off their heads or pierce their hearts. Any other injury is healable, including having one's head cut off or blown to pieces, if a Pureblood uses the blood of another Pureblood to heal them. When a Pureblood vampire is killed, their bodies slowly disperse into small sparkles before shattering into shards of glass.

It is heavily implied that each vampire has a unique power such as Rido Kuran's ability to manipulate his blood or Shizuka's control over plants. Their blood is highly prized and many have attempted to drink their blood, this includes both humans and Noble vampires. The blood of a Pureblood can give vampires new powers.
