Dr. Narutaki, a genius who is trying to preserve true Japanese men, not the losers they are today, needs semen from 100 specimens. The problem is these 100 specimens wouldn’t give it to him voluntarily, so he comes up with a plan. He gets Marine, a sexy girl from an all girl school, and put her in a special sexy costume that changes to a mans desire and won’t come off until she gets all 100 semen specimens. Now to get in her way, South Pole One, a sexaroid created by the doctor’s assistant, is interfering by exhausting and taking the men’s semen first, making it a race.
