Lord Yoshikawa is dying, and his final wish is to be reunited with his son Rokuo, a young samurai forced into hiding after killing the son of Lord Hojo in a duel. Unfortunately, Hojo's retainers are also searching for Rokuo, and their intentions are anything but nice. It's up to Usagi to find him, race him through a gauntlet of swords, and get him to Lord Yoshikawa's side before the old man draws his final breath.
