Yukie Sano

She is the most mature of Rina's friends. Additionally, she is the only one who has a boyfriend named Reiji Nakama who is older than her and already attending a university. Much like Masashi, she can get mad very easily and gets out of control. Because of this, Masashi is very scared of her when she is like this. She does have a soft side however, she is rather creative and is one of the best at her studies.
