During the war between vampires and humans a thousand years ago, Shura, the child of humans and vampires, became an important force.
Those who join the vampire camp are called Dark Shura, and those who join the human camp are called Holy Shura. After the war, the vampire leader Hades put Shura on trial. Shura's abilities were sealed, and only by sucking magical blood can all his energy be released.
This gave rise to a brand new profession, Shura Contractor.
