She is one of the three JK part-time workers and the most popular one at the store. She is a loose-fitting girl with a charm point of her ample breasts and a soothing smile. Her sweet talk and smiling face are a skillful manipulation of men's hearts, but she has a natural disposition that she is unaware of. She has a loving boyfriend who calls her all the time even when she is at work, but she is unfaithful and has a strong sexual appetite, and has many playmates. She has a strong following at the store, especially among the older men, and many of them go to the store just for Yuka. [From official site]
