Tokugawa Shige Shige, the Seii taishōgun of Japan. His role in controlling the country is not great because of the passing of his late Father (and the Amanto invasion), so he looked up to Police chief Matsudaira as a sort of father-figure.
He appeared in several episodes being led around by Matsudaira to cabaret clubs and so on and met Gintoki and the people of the Yorozuya through the progress and is often harassed by Otae and the girls.
