Levius est 10.

It’s the 19th century, and the world has entered the Era of Rebirth, recovering from the devastating flames of war. The sport of Mechanical Martial Arts has galvanized the nations. Cybernetically augmented fighters turn their blood into steam and their bodies into brutal fighting—and killing—machines.

Young Levius is one of those arena battlers, hell-bent on winning so he can simply survive.

The time has come for the final fight between Levius and the powerful Arthur Graynore, founder of Amethyst. Their battleground? A secret underground ring hidden deep beneath the championship arena. As the blows begin to fly, Levius starts to see the true reason for the existence of the M.M.A. and realizes he must survive and win this fight…at any cost.
