Sawatari Nadeshiko

Twin sister. She is a gentle, calm, and caring "kind older sister".

She is a woman of her own pace and has a ladylike atmosphere. However, she is also a bit preoccupied and worried about the main character. She prefers to read books quietly by herself rather than to be outdoorsy, and she doesn't seem to have many close friends.

She has been a domestic helper since she graduated from school. She grew up in an all-girls' school like her younger sister Kasumi. She has never been in a relationship with a man, so her knowledge of the opposite sex is a little off.

She thinks of the main character as her "cute and precious little brother," but she still sees him as a kid and is a bit overprotective of him.
