Usagi Yojimbo: Lone Goat & Kid Vol. 1 #5

The Way of the Samurai Usagi befriends a famous general from the Great Wars. General Oyaneko was a loyal vassal to his late lord, but his son had refused to listen to his counsel and demoted him to become a magistrate to a small provincial town. Now disgraced and with no lord to serve, the General feels there is only one way to regain his honor as a samurai: challenge Usagi to a duel to the death.
