遠海 佐奈

Satoru's cute younger sister. She does most of the housework. She really disapproves of him being an otaku and will often yell at him for playing eroge and is prone to kicking him when she's mad. She calls him "aniki" rather than "onii-chan".

She attends the middle school next to Satoru's high school and wears a different uniform than the other girls.
