About one in ten girls spontaneously undergo a process called reduction. This can happen at any time while a girl is between 18 and 20 years of age, and results in the girl suddenly becoming eight times smaller in size, so typically around 20 centimeters (8 inches) tall. A side effect is an increase in voice pitch, proportional to the reduction in size.

A girl who experienced reduction is colloquially known as a "doll". The law states that a doll is not considered to be a human being anymore. Instead, she is property of the first person who finds her. Owners have to fulfill their dolls' needs, like food and shelter. In exchange they're allowed to use their doll in any way they wish, as long as it doesn't cause the doll any physical damage. With the owner free to touch and play with their doll however they want they are typically used to satisfy the owner's urges and fantasies. Another side effect of reduction is increased sensitivity to touch, which makes the doll even more attractive as a sexual plaything.
