Legend of Duo
In the early 21st century, humanity faces extinction after losing "purana," the vital essence that sustains all life. A vampire named Duo refuses to let mankind perish and reveals the secret of purana to save them. But like Prometheus, who was punished for giving fire to humans, Duo faces consequences for breaking this taboo. The one sent to punish him is Zieg-his closest friend, or perhaps something even deeper.
