Alright so I just watched Darker than Black and I really liked the characters and the story. Yin is a young women (in her teens) who is a "doll." She can find certain people by touching water with her hands or feet. I think Yin is absolutely adorable! XD She is quiet but cute. It seems she has some feelings towards Hei and he has feelings for her too, but who really knows - _-
Even Though I'm a Doll I still love you.
