[What are Dolls?]
In this world, dolls are intricate humanoid figures crafted to resemble humans. They vary widely, from machines with programmed thought processes for commercial use to dolls imbued with souls that possess emotions. Their sizes range from small to large, but many are about the size of a human. Their purposes include serving as substitutes for maids, love toys, or objects for display. New dolls are expensive and out of reach for commoners, but used ones are relatively affordable. They have no human rights.
