Battles continue between "Penguin Empire", the mysterious life form which arrived on earth all of a sudden, and "Beauty Salon Prince", the secret anti-Penguin organization.

They choose Koichi Madanbashi, a hot-blooded high school boy who is mad about big boobs, because he is the factor of "Hi-ERo particles", the source of unknown energy.
