Kikko is Tani's wife. She appeared in a couple of special episodes over the course of the series; the first time was in a short sketch set in her and Tani's 'house'.
In her second appearance Kikko had a much bigger part. She sent Tani off across the world to find international contestants to bring home and storm the castle. While he was away, Kikko filled in as the General to lead the day's Japanese contestants through the games.
