As the mighty star fleet of the planet Keron prepare their invasion of Earth, Sergeant Keroro and his elite team of commandos have been sent to infiltrate the enemy strongholds and gather as much intelligence as possible. However, it seems even his extensive military training is no match for the forces of Earth, as he is discovered and captured by the two middle school siblings, Fuyuki and Natsumi. Submitted to the rigorous torture of housework duty, the amphibious Keroro must now bide his time, covertly locate his squad-mates, and resume his mission of conquest!
