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!
Shinnojo and Iori clash swords for the right to stand as head of the Ogame style! However, their battle fails to reach its conclusion. Iori gives Gama his “last lesson as his mentor” before leaving the Ogame style and its members behind as they each begin to walk their individual paths. Everything is for the sake of bringing Naoyoshi back and taking Jinsuke down. Meanwhile in Juren Village, Gama and Zenmaru find themselves training under a new master by the name of Kashitaro!
