Pure blood

A Pureblooded is vampire that has no trace of human blood in their ancestry nor has it been tainted by the blood of average vampires. They are the most powerful type of vampire, but are only a very small portion of the vampire population. Marriages are focussed on keeping the family and bloodline pure and because of that it's not unheard of, for siblings, cousins and other family memebers to marry as it is essential to keep the bloodline pure. Another option is to marry a memeber of another pureblood family.

Purebloods are treated like royalty mainly because of their power and rarity, and because of this, purebloods are considered "treasures" by the Vampire Council. The Council hold Pureblood's powers in extremely high regard but fears their powers especially the power that lets them control lower vampires. It is taboo to kill or to even harm a Pureblood. Other vampires lust for a pureblood's blood, more than their lover's making them the perfect prey whom they try to hurt with words.

Purebloods live longer then most vampires, so, a pureblood can not die of illness or any other cause. They can only die if they commit suicide or are murdered. It's said that most purebloods kill themselves because of the long lifespan a pureblood lives. Their are only seven pureblood families left, Kuran, Hiou, Shirabuki, Ouri, Hanadagi, Touma and Shoutou. Before the birth of Yuki Kuran who is youngest pureblood at the age of 16, their were thirty three Pureblood vampires of which the Vampire Council controlled nineteen of them, the rest on them had been away for a long time.
