Dragons have been extinct for centuries. Hunted by humanity without knowing the dragons were created to protect the world from beings of the Nether world. The spirits of the strongest of the dragons lived on in the souls of 12 royal families of the world.

In modern times, revolutions had taken power from royalty and their decedents live normal lives. Raoul is one of these decendents and inherited the soul of the Obsidian Dragon of Crimson Soul.

Raoul lives the life of a mechanic and vigilante with the power of a dragon, shown by his right arm. While others are creeped out by his dragonic limb, he wears it with pride and will rarely cover it up. He knows there are others like him out there and works to locate them to understand the history of the dragons and his own family.

Raoul can send powerful energy blasts from his arm, though this takes a lot of stamina. He's a talented boxer and biker as well as wielding a sawed off shot gun. He's a grungy street wise punk of sorts who feels the plight of those around him, and works to help any one in need from those in power who abuse their power.
