Unabara Domain—home to nightmarishly strong students and masters of martial arts of all kinds. The lord of the Unabara has decided that whichever of his sons discovers the strongest martial arts style will be his heir, but when 28th son Naoyoshi Washizu decides on Ogama-style practitioner Gama Kurogane, son of notorious father and scion of a “weak” style, to represent him, the odds seem bleak. But between Naoyoshi’s determination and Gama’s hard-earned strength, they may yet come out on top!
Just like that, the Grand Tournament of Unabara has suddenly come to an end. The tournament itself was only a set-up to Gama’s father Jinsuke's grand scheme to take over the country… And in order to achieve that goal, the Muho style has abducted Naoyoshi after completely and utterly defeating Gama. In order to get Naoyoshi back, Gama vows to become stronger than ever! Gama and the others head to “Juren Village,” a sacred ground for the Ogame style, to begin their training!
