Ayane Shirakawa

Chilhood friend of Kazushi Sudou and the older sister of Kotone Shirakawa. The older sister of the Shirakawa sisters. The type who is highly conscious of beauty and is busy polishing herself, such as saving pocket money to purchase beautiful skin bath salts. She tends to reflexively take a twitchy attitude towards Kazushi, but the truth is, she is worried and can't be honest with herself.
