"To Die is to Live"

Those are the exact words that each vampire lives by.

Most of the vampire population were once human, all except for the 4 Noble Bloodlines.  They orginate across the globe from Europe to Asia to the Americas.

But soon, the vampire race is threatened.

Vampire girls are ending up dead; bodies and heads separated with no shred of mercy found.

200 years have passed, and the vampire population is dwindling.  That is, until one day, on a cold December day, a beautiful baby girl is born, with not one, but two golden markings on her back.

Afraid for their daughter's sake, the parents hid her identity and her markings.  But sacrificing their lives to protect her was not even enough to shelter her from her fate.

Departed from the earth, the parents knew little of the Nobles who were well aware of their daughter's existence and were watching over her carefully.

It was not one, but two forces.

Now 18 years have passed, and the baby girl has blossomed into a beautiful young lady.

Though her parents are gone, she's maintained a beautiful personality.  As well as 12 beautiful friends, better known as Exo.

But on her 19th birthday, things took a turn for the worse.

She died.

But through death, she lived once again, breathing the same air, eating the same food, walking the same street, with one exception.

She didn't remember anything, about who she was, about her past life and about Exo.
