Fuutarou has always lived in poverty and hated it. Because of his past he had become obsessed with money and will do anything to obtain it.

Beast-Fist is a form of martial arts where the powers of a beast can be acquired by sensing the beast in their hearts. There are two relative schools of the Beast-Fist. One, the Beast-Fist of justice, Geki Juken Beast Arts. And one, the evil Beast-Fist of Rin Juken Akugata. The two schools of warriors learn and change in order to increase in power every day, as they are destined to clash.

A samurai lord has bartered away his newborn son's organs to forty-eight demons in exchange for dominance on the battlefield. Yet, the abandoned infant survives thanks to a medicine man who equips him with primitive prosthetics—lethal ones with which the wronged son will use to hunt down the multitude of demons to reclaim his body one piece at a time, before confronting his father. On his journeys the young hero encounters an orphan who claims to be the greatest thief in Japan.
