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 before reaching the Unabara Domain, the Ogame style find themselves under attack by the Muho style’s 47th corps, users of the powerful enhancement drug: the “Jugan” pill. Gama and the others wind up being split and surrounded by “super soldiers”, but Gama manages to ward off his enemy with his special technique. However, Ginki awakens to a new height of superhuman power with his second “Jugan” pill and comes back with a next-level attack! The fierce showdown between Gama and Ginki has begun…!
