姉川 絢音

Likes: Shun, doing housework, friends
Dislikes: Holding herself back

Mio's friend who is like a second older sister to Shun, as she takes care of the household chores for him due to Mio being busy with work. She is understanding of Shun's circumstances and keeps a certain distance from him, but at times she'll also pamper him with her "sisterly love." Similarly to Hinano, Ayane becomes more aggressive in her pursuit for Shun after Ena's confession, as she realizes she wants Shun all to herself. She likes sexual things and is open to trying out any kind of sexual plays.
