The very beautiful sister of Yuri. She is the oldest of the siblings who came to live with their mother at age seven. She is not married and she does not have a job. She tends to be very lazy and sleeps often because of her "stomach problems" and "headaches" and "low blood pressure". She is the nicest to Yuri when she first comes to the house, but still teases her and orders her around. She likes to drink milk tea.
