Honoring his father's memory by avenging his untimely death is a duty that young samurai Jintetsu holds close to his heart. However, the culprit who mercilessly killed his father happens to be a corrupt government official. In response, those in power have declared an all-out manhunt against Jintetsu, treating him like a savage beast. Despite the challenges he faces, Jintetsu is determined to succeed, even if he is no longer among the living.
After being brutally mauled by a pack of hounds, Genkichi discovers Jintetsu's shredded corpse. As an outcast and a skilled inventor, he rebuilds Jintetsu's lifeless body with an indestructible steel exterior and a sentient sword that speaks at his owner's command. This new form is exactly what Jintetsu needs to confront the criminal organization responsible for creating chaos within his hometown, as well as the gang leader who orchestrated his father's murder. However, the one thing that his steel armor cannot shield him from is the aching desire for the beautiful Otsuki, whom he had to leave behind.
