Vincent is a short tempered orphan, blessed with a super-human strength and living on the streets of the Ryuuga Ghettos.
One fateful day, he is confronted by a man more powerful than himself and recruited into the ranks of GRAVE; a secret anti-terrorist organisation who's members also possess strange abilities.
Situations become more complicated when an entity known as the Wrath is awakened and enters Vincent's body. Now having to come to terms with his new and deadly powers, Vincent is thrust head first into a world he never knew existed.
However when an ancient, cannibalistic demon surfaces from the shadows of history and leads an army on the world, it falls to the members of GRAVE to stop them and save the world from total annihilation.
Armed with a power that had been exiled for a thousand years, can Vincent be the key to the world's salvation or its demise?
