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.

Pureblood Abilities
Pureblood families have different abilities.

The Kuran, Shirabuki and Ouri family has the ability of a normal Pureblood, common but strong. The Shouton Family has the ability to see the future and to stay alive even without drinking any blood of a human or vampire for quite a long time. The Hanadagi and Touma family has the ability to stay alive without sleeping and drinking blood  for 400 years. Only the Hanadagi family has the ability to create small floods, massive earthquakes and small tornadoes.They are still hibernating. The Hiou Family can sleep for a very long time (not hibernation) and not wake up.They only wake up when a trigger or a feeling is felt be those  sleeping Purebloods.

Although Hibernation is necessary for Purebloods, the Hanadagi and Touma family can stay alive even without sleeping or drinking of blood. Many look up to them as their leader.
