Kurosaki, Sayoko

黒崎沙夜子

Sayoko possesses a notably dark personality and lacks responsibility. In the manga, she is depicted as suicidal, although this trait was removed during the adaptation to anime. Despite this alteration, she remains irresponsible in both versions, yet she desires to make Asami happy and live with her for a long time. Their room is cluttered with cardboard boxes, which serve as furniture and bedding due to their extreme poverty. Her father is a wealthy sculptor, from whom she became estranged in her youth. Her favorite food is Mizuyōkan. Although she appears useless throughout the series, she genuinely cares for Asami. While her age is not disclosed in the manga, her birthday is October 17.
