Forbidden Doll x Town Doctor

Once, people possessed dolls known as Les Vides Dolls... commonly called Vide Dolls.

Vide Doll...

They have faces and appearances as beautiful as French dolls, yet they breathe, eat, and bleed red blood like humans. Vide Dolls were originally empty French dolls. A soul—the source of a doll's life—is placed within them. By doing so, they move and live no differently from humans.

However, there are differences from humans. First, they possess no vocal cords. They cannot speak and only obey their master. Furthermore, their essence is that of a doll... meaning they are not equipped with human emotions like sadness or joy. They have no hearts.

Vide Dolls were all obedient and followed any order from the "master name" engraved on their thighs.

They handled everything from housework and cleaning to manual labor.

—Because that was their everything. To them, orders are life; if no order is given, they do nothing—no, they cannot do anything.

Their public face was that of dolls living alongside humans. That was only at first; humans gradually began to treat them as "possessions," like mere objects.

Bombs were planted in their bodies to use them as weapons in wars, they were forced to work as slaves, and eventually, underground medical trading for their body parts took place.

However, eventually, the government cracked down on Vide Dolls as forbidden taboos, and they began to disappear.

Those who loathed the idea of them living as humans pressured the government to regulate Vide Dolls. Gradually, Vide Dolls were no longer seen. The government established a law:

"Vide Dolls are to be disposed of immediately upon discovery."

Vide Dolls found were shot on the spot; if captured, they were disposed of. That was the law.

Even so, masters who could not let them go were caught and sometimes subjected to heavy sentences.

From there, the government created laws, and Vide Dolls became legends as "Forbidden Dolls," now heard of only in rumors.

—Ten years have passed since those major incidents.

Lucien, a town doctor in the countryside, lives as a physician in his old wooden home.

One day, after finishing his afternoon consultations, he was preparing to clean up. Taking off his white coat, he happened to glance out the window and saw someone sitting at the entrance. Curious, he opened the front door to find a boy/girl deeply covered in a white cloth. When a gust of wind blew the hood back, there was a boy/girl of breathtaking beauty. Lucien, unable to leave them be, invited the silent child inside to treat them for free.

While treating the child, whose gender he couldn't discern, he noticed something engraved on their thigh.

"master name ○○・○○"

It was proof that this child was an illegal existence. A Forbidden Doll—this battered child was one of the survivors...

What will Lucien do with the surviving Forbidden Doll, and why is this child here...?
