Doll

Dolls (ドル, Doru) are an emotionless humanoid species used by the world's governments and criminal underground for reconnaissance.

Overview
Dolls, like Contractors, appeared ten years before the start of the series. Most Dolls were once Humans, however, some Dolls can be "made" to mimic human form. Dolls have no emotions, and cannot think for themselves. It can, however, be given the memories and personality of another person and assume a person's personality perfectly, mimicking all their habits, dreams, and feelings until the time is right; making them into the perfect sleeper agents.

Interestingly enough, a Doll by the name of Shinoda Chiaki seemed to have some "life" of her own by saving Hei from being killed by another Contractor. This suggests that Dolls, like Chiaki, can go beyond their "set" characteristics and become something else. Other examples include when Huang discovers Yin crying, July expressing confidence in himself, and Sakurai, a doll stolen by the yakuza, smiling as she runs away with one of their own.

Abilities
Like Contractors, Dolls have abilities that make them unique.


 * Observer Spirit: An ability unique to Dolls, Observer Spirits are ghostly specters that Dolls can use for reconnaissance missions; their primary function. Each Doll has a unique medium (i.e, concrete, water, etc) that they can send their Spirit through. As long as their target is either touching, or near their medium, they can spy on that target for as long as they wish.
