Miyata promises Aizawa a promotion and orders him to infiltrate a rival company and steal data on a gene-altering drug. Aizawa complies because losing his job would leave him unable to help his sick father, but Miyata reneges and threatens him after the theft. Enraged, Aizawa knocks his boss unconscious and forces him to swallow the drug; by morning, Miyata has transformed into a woman, setting up the repeated creampies and pregnancy promised in the title.
