Yin (銀, In?, lit. Silver) Voiced by: Misato Fukuen
A supporter in Hei's team. She is an emotionless spirit medium known as a "Doll". Very passive and speaking rarely, she is described as having no emotion and incapable of such processes (however as the series progresses she shows a slight human side with hints of emotion). Her primary function is to locate individuals, usually assassination targets, for the team. For this she uses her ability to see anything near water when she is touching water. Before the appearance of the Gates she lived in Finland as Kirsi (last name unknown) learning to play the piano under the tutelage of famed pianist Eris Kostinen.
