Ayako Suzuki

Ayako Suzuki is Sonoko's older sister and has a good relationship with her. As a graduate student interested in film, she was in a film club while an undergraduate, holding the role of head of makeup and costumes, and hosted the club reunion.

In total contrast to her younger sister, Ayako is much more polite, kind, and lacks the snobbish and shallow attitude Sonoko often displays. She acts relatively happy and she always appears as if she has her eyes closed, which is not an unheard character style in manga and anime respectively.

According to Sonoko, Ayako is not a summer person, and dislikes being out in the sun, but she went to the family's summer villa for the chance to see her fiance.
