Prior to being introduced to Mele, Haku uses his Gengi to control children easily taken by it. Having them go to his Unicorn Palace, Haku intended to have them amplify his Gengi's affects worldwide to gather the despair of devastated parents. But actions of involving children, especially Natsume Masaki, made it personal to Miki Masaki as she personally destroys Haku in SaiDaiOh. Despite his cowardly techniques, Haku speaks and acts like a medieval knight.
