Naoko Sakisaka

Оригінальне ім’я: 向坂ナオコ

Rikuo's older sister. College student. It seems she's popular on campus, but at home she's lackadaisical to the extreme. She treats androids entirely as "things", epitomizing the attitude of her contemporaries, and detests "android-holic" types. She sees hints of "android-holic" tendencies in Rikuo.
