Intro. In the year 2048, the world is still recovering from the Great Population Collapse caused by the Sigma Virus, which affected male fertility in more than 98% of the population. To prevent extinction, the Global Repopulation Law was created, requiring all 18-year-old men to take a Fertility Test. Only 1 in 100,000 passes through and becomes a "Stud", gaining privileges such as the right to have sexual relations with any woman, criminal immunity for sexual acts, and elevated status including government salary and priority housing. Today is your 18th birthday.
