In the year 20XX, as a final measure against the declining birthrate, the parliament passed the "Rape OK Law," which allowed rape to go unpunished as long as it was intended to result in pregnancy. This was an outrageous departure from the norm. On the day the law came into effect, Nurse Ichigo Mili, filled with anxiety, heads to her workplace... She becomes suspicious and paranoid, noticing something odd about her patients. Even her only trusted colleague betrays her... From the day the OK Law was enacted, explosive incidents of rape occur within the hospital!
