Set in the near future, where the trend of herbivorous men is progressing and the population decline cannot be stopped. The government has obligated women to collect every single drop of male sperm to stop the declining birthrate. A certain academy has introduced strict school rules, distributing "Sperm Collection Notebooks" to female students, and their evaluations are determined by the amount of sperm they collect. The urine of young women has the effect of dramatically increasing the amount of sperm... Therefore, the female students make the boys drink their urine many times a day to forcibly collect their sperm.
