Appears in <i>Ayatsuri Yashiki</i> (Marionette Mansion). Yukihiko is the oldest of the Kitawaki kids. He and his family live in a truck and travel all over Japan, performing puppet shows. He is very skilled at it and his favorite puppet is Jean-Pierre, but feels that they are actually the ones controlled by the puppets, and not the other way around. Like Haruhiko, Yukihiko also wishes that they'd settle down somewhere and make friends; he eventually has enough of it and runs away from home.<br /> <br />
