Duklyon battles the evil Imonoyama Shopping District, whose goal is world domination. This group is headed by Kotobuki Sukiyabashi, a shy good-natured classmate of Kentarou's and Takeshi. The Imonoyama Shopping District goes to unique ways to ensure their goals, taking various classes hostage, hijacking the lunch room, and even kidnapping Utako Okawa, the Elementary School's student body president. But Duklyon always shows up to save the day.
