Yin

Resumen

A member of [Hei](https://anilist.co/character/2160/)'s team, an emotionless spirit medium known as a "Doll." Her power lies in tracking and observation through direct contact with water. [Huang](https://anilist.co/character/2164/) mentions that her "program" is a minimal one, incapable of showing emotion or even allowing her to make decisions for herself; however, she later debunks this by making the decision to keep working with Hei and the others when given the choice of leaving, a possible sign of her recovering her humanity. ~! Yin is of Finnish origin and her real name is Kirsi. She was once a student of a famed Finnish pianist named [Eelis Kastinen](https://anilist.co/character/23856/), who slowly started developing a love interest in her mother. Yin's father died in a plane crash. !~
