Once a renowned high school known for its martial arts prowess, Hakuo Academy faced a bleak future as rival school Seishikan resorted to underhanded tactics to poach its top students. To turn the tide, Hokujo Hikoko, the head of the board of directors, dispatched a messenger to the legendary Fuma Village. The Fuma Clan, skilled ninjas capable of astounding feats like running thousands of miles in a day and hearing a pin drop from three miles away, answered the call. Their leader chose Kojiro as the envoy to Hakuo Academy. Upon arrival, Kojiro found himself embroiled in a fierce conflict with the Yasha Clan, allies of Seishikan, and faced his most formidable adversary, Asuka Musashi. Musashi fought relentlessly for his ailing sister, who was afflicted by an incurable illness.
