One-eyed Ichiro was a bandit that, along with twenty or so bandit henchmen, terrorised villages in several provinces. A large price on his head attracted bounty hunters, one of these being Gennosuke. Ichiro holed up in a temple with the priests as hostages, keeping authorities and townsfolk at bay.

Gen, with Usagi as his yojimbo, stormed the temple and found Ichiro with his blade at a priests throat. His bluff called, Ichiro threw the priest behind him. The priest was in fact Ichiro's brother, Kenichi, who made a sneak attack upon Gen. The attack was unsuccessful however and Ichiro was slain.
