Doll is an interpretation of the Quiet One trope — introverted and taciturn.

Doll rarely spoke to anyone, talking occasionally with her friend Lizzy and giving enigmatic non-answers to questions anyone might have. As well as being quiet, Doll lacked any interest in expressing herself to others under the assumption that no one understands how to help her. She have something like magic named "AbsoluteSolver". She hates V because V killed doll's parents. She trying to hide her AbsoluteSolver.
