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!
In the dungeon of the main castle, the battle between Iori and Ango Kuryu has begun. Kuryu comes at Iori with a slash of divine speed, produced by his super-heavy nagamaki longsword. How does Iori plan to survive an attack which he can neither dodge nor receive head-on?! Meanwhile Gama has finally made it back to Naoyoshi, just in time to rush head-first into battle with Ranmaru!
