Darker than Black: Yin

A member of Hei's team and an emotionless spirit medium known as a "doll."

Her power lies in tracking and observation by way of water. However, this power only takes effect when she is in direct contact with water. Huang mentions that her "program" is a minimal one, incapable of showing emotion or even allowing her to make decisions for herself, though, she later debunks this by making the decision to keep working with Hei and the others when given the choice of leaving.
