Levius/est, Volume 5 by Haruhisa Nakata

As society rises from the ashes of war, cybernetically augmented arena fighters battle for fame and fortune…or die trying.

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 main event of the Southern Slam tournament is Levius’s title fight against "the Emperor," Oliver E. Kingsley, but first Natalia must face off against A.J.’s brother Balthus. Zack and Bill are ringside to help, but the Amethyst corporation’s experiments have turned Natalia’s opponent into a dreadful new kind of weapon!
