桜庭 湊

Koutaro's step mother.

She and Misako, Koutarou's biological mother, have known each other since childhood. She married Koutarou's grieving father, after the death of his wife shortly after Nagisa was born.

Since then, she has been taking care of household responsibilities while making the family supermarket business prosperous.

She is the ideal mother, perfectly capable of handling all household chores, sometimes kind and sometimes strict. In reality, she is an extremely lonely person who cannot survive without someone's support,

However, she only shows this side of herself in front of the man she really loves, Choichiro.
