Yoko has straight, blackish brown hair flowing to her shoulders, and has a fringe. Her eyes slant upwards, and are bright blue.
Yoko is very shy and timid, she doesn't really make her own decisions, relying heavily on her friend, Kimura Miki. She's smart in studies, but she's too timid to stand up to Miki, who's manipulative and takes advantage of her.
She resembles Amane when she (Amane) was a kid.
Yoko has been close friends with Miki ever since they were young kids, and has never separated from her since.
