In 20XX, humans are on the verge of extinction. Due to low birth rates (especially for boys), the current male-female ratio is 1:10721. The world leaders decide to pass a new law to combat this crisis: The New Sex Law. All males receive a card called the “Free Sex Licence” which allows them to have sex with any female once it is shown. Obviously, there was much opposition to this and the results were very disappointing. To reduce the loss of vital sperm, a series of rules were imposed. Among them: no masturbation, no birth control, no non-vaginal sex. Will these drastic steps save humanity?

Takumi’s childhood friend who lives next-door and Rin’s elder sister. Contrary to her very adult-like appearance, she loves teasing people, especially Takumi. Furthermore, she loves making fun of him as well. She doesn’t seem to hold any romantic feelings towards Takumi, treating him more like a little brother. Though, later on, because of the license allowing them to have intercourse, her feelings (toward him) gradually start to change (for the better).
