Saint Seiya ~ The Version of the Underworld

(This version will be more or less from the movie but by memory. Including there will be some will be by my own words.)

In ancient times, vampires/Death Dealers and Werewolves/Lycans lived separately. Until the strong Death Dealers and Lycans, stands out of the rest and lived as legends. They are known as War Lords, leaders of the packs or colonies from either side, and fought for territories for many years. But a secret prophecy begins to stand within their way...

In Japan, two young Lycans and two young Death Dealers are followed by the same order from their leader that lives in the same place. But different superiors. To hunt down two colonies/pack of War Lords but never notice what secrets they would discover from their enemies' ambition. A young man begins to stand in the crossfire of the two and soon becomes a target. However, something special about this young man holds the key of both Lycans and Death Dealers alike.

Can these two Death Dealers and two Lycans work together and rebel against what has been ordered, so they could help this young man? Or will it be their downfall?
