Bunta Takakura

The principal of Action Kindergarten, his Yakuza-like appearance is often misunderstood by the people in the neighborhood, which often acts as a recurring joke in the series (often worsened by Shin-chan by calling him "Kumichō" (組長 ,Godfather?)). Actually he has a tender heart and good attitude. He masqueraded as a superhero called Enchoman but Shin-chan found out his true identity easily. He is shown to like women's wrestling in one episode.
