Battles continue between the "Penguin Empire," a mystery life form that appeared on Earth unexpectedly, and the "Beauty Salon Prince," a hidden anti-Penguin group. Beauty Salon Prince has invented their ultimate weapon, "Daimidaler," in order to combat Penguin Empire's massive "Penguin Robot," and is currently seeking for a pilot. They select Koichi Madanbashi, a hot-blooded high school kid with a penchant for huge boobs, as the factor of "Hi-ERo particles," the source of unknown energy.
