沢渡 京香

Takuto's wife. She works as a part time lecturer for high schools and universities. She is a very caring and helpful person even to strangers, and because of her straight forward personality she often overdoes things causing her to blunder.

She has a very unyielding personality and hates to lose, yet when it comes to her husband she is quite obedient and listens to whatever he says.
She sees herself as Takuma's real sister and teases him a lot.
