Ane Mirai, a 19-year-old active female college student with a friendly smile and a plump body, makes her AV debut! The origin of her slightly unusual name is that she has a habit of saying, Um... when talking to her friends and family. She is usually a serious girl, but for the past two years she hasn't had a boyfriend and is lonely, so she comforts herself with a vibrator. At that time, she admired the AV actress she was watching.
