Translated as "Phantom Child," Genzo (幻児?) is an eyepatch-wearing Shinma who wields a Kusarigama in battle. He is the brother of Genta and Genji and the youngest of the three. They attacked a town and killed some of its villagers. They wanted the village chief's daughter Sato for their bride. When they came to the town the next day to claim Sato, they encountered Miyu and Reiha. Genzo used his chain to wrap Miyu's arm. When Larva didn't come, Reiha used her ice attack on Genzo. Miyu sent her fire attack along Genzo's chain and Genzo ended up returned to "The Darkness."
