In the near future Japan, as part of measures to combat declining birth rates, adult males are legally required to donate sperm to the state. This policy is officially enforced as "Piss Drinking Order Article 9, Section 9," and violators face severe punishment. The penalty involves prisoners being forced to drink the urine of female investigators—an extreme and degrading treatment. Female urine contains a special component that promotes sperm production, and authorities claim this method makes sperm collection more efficient. Prisoners are given no other source of hydration and are made to consume large quantities of urine multiple times a day. Their bodies pushed to the brink, they eventually collapse unconscious after being forced to urinate up to 23 times. Resistance leads only to brutal, hellish violence.
