who is in the 花 arranging club along with Sakura.
She is quiet and thoughtful.
According to Sakura,
she has a brother and sister in 大学 and junior high,
and that all three of them look alike,
they also all wear glasses.
Shizuko is often the one to tell Sakura off for making rash decisions and behaves maturely and logically like a mother.
She is very strict and finds meeting strangers,
attending concerts and going on trips a nuisance.
