Mirumoto Sanzo left the Dragon Clan after his family was slaughtered by ogres, becoming the noted ronin Sanzo, a samurai without a daisho who rode a horse that was better kept than himself. This former samurai of the Dragon Clan interested Miya Yumi so much that he took on Sanzo as a yojimbo and took this time to study him. Yumi was so moved by Sanzo's story that she replaced Sanzo's missing daisho. Musha was the name of his loyal mare, who served him both in life and death.
