With the sudden passing of the Niigata representative Tonomura, his seat in the Diet is up for grabs. Clumsy country girl Hoshina Natsuki signs up for the position, running under the Heroine Party.
Natsuki wants to help Ryusekidou Chinatsu of the Sunlight Party fight off pollution in her hometown, but she has a bit of a complicated history with Onimaru Shizuka.
A spat during a Diet session leads to the Idol Dietwomen facing petty retribution during a swimsuit competition. They respond in a way that only Idol Dietwomen can.
Natsuki becomes the Chief for a Day at the local police station. She negotiates with hostage takers at Kamekame Preschool.
The New Subculture Party tries to launch a bottle rocket event at the Diet building, but Dietman Inagawa returns with his usual obstructionism. The Heroine Party lends the New Subculture Party a hand.
