Released by Monkey Fist to help him find the "weapon". After making a pact, Yono goes to Yamanouchi where he easily takes care of Kim, Rufus, and Master Sensei, turning them all to stone. When Hana beats his summoner, Monkey Fist, everyone is returned to normal and Monkey Fist himself is turned to stone and sucked into the earth as he followed the "Path of the Yono".

Personality
Yono is evil, he was neither ruthlessly nor mindlessly evil, and either required or preferred having a worthy summoner to direct his power.
