五ヶ谷 羽耶音

A third year in the school, is Kanade's older sister and Souji's first love, he's been calling her "Haya-nee". Although she's just a year older, she appears to be even older and is like tolerance incarnate. She immediately hugs people close to her and compliments them along with a pat on his head. She is bad at cleaning her room and cooking, but her skill at making sweets is on the level of a pro, her crepes are especially good. She sometimes staggers and has problems holding her balance, which is blamed on her "extremely self-asserting big breasts". She often walks around her home without a bra, or wearing just a towel after coming out of the bath.
