Real name: Kirsi.

Yin is a short, blind, slender doll from Finland in her early-to-mid teens with silver hair & purple eyes.

Dolls are emotionless spirit mediums who can project an observer spirit, a disembodied aura which can remotely access areas considerable distances from the Doll, allowing the Doll to observe what is in the area. Dolls have different mediums through which they can send their observer spirits & must be in contact with this medium while observing. Yin's medium is water, through which she can send her observer spirit anywhere else there is water.

Yin keeps her long silver hair tied back with a purple ribbon. She wears a dark purple dress with black hem & a short black bolero jacket which covers her neck, shoulders & arms. Her outfit is completed by black thigh-high socks & black mary-jane shoes.

Yin is unable to emotionally or verbally express herself due to being a doll & thus, lacks free-will. She can only act & make decisions when ordered to do so.

There have been instances of dolls developing free-will overtime...
