Centuries ago the king of Saint Pheliosta, and the Vampire King, Duzell, had a monumental duel. Duzell was defeated and swore that he would fight again in his next reincarnation. Reborn as a wildcat, Duzell is picked up from the wild by Ishtar, the great-granddaughter of his nemesis, Phelios. The fate of ages is reborn and the vampire game begins.

And, oh yeah, did we mention that this is a comedy?
