As the opening credits roll, an abbreviated version of Ogami Itts Tomisabur Wakayama past as Shogunate Decapitator and his wifes murder by ninja are seen, with Daigor Akihiro Tomikawa providing the narration.Two hooded samurai attack Ogami while he is pushing a cart with Daigor inside. Ogami fends off the attack of the first, breaking the samurais sword and splitting his head. The second attacker jumps over the first, with the first still clasping Ogamis blade. Ogami pulls off a handrail from the cart and a blade comes out, transforming it into a spear. Ogami then uses the spear to impale the second attacker. As the first is dying, he reminds Ogami that he is marked for death. ........
