Marilyn Willow

Dr. Marilyn Willow is the personal assistant of Dr. Narumi Narutaki, a scientist who is trying to preserve true Japanese men by collecting semen from 100 specimens. He gets Marine, a girl from an all girl school, and put in her a ring and a special costume that changes to a mans desire and won't come off until she gets all 100 semen specimens. Dr Marilyn, being jealous of Marine, creates a sexaroid called South Pole One in order to interfere with her by exhausting and taking the men's semen first, making it a race against time.
