田辺 美佐子

Yuuichi's step mother. She used to be a nurse and by coincidence was in charge of caring for Yuuichi's biological mother who died after childbirth. After Yuuichi's birth, she supported his father who was mentally devastated. She went on to marry him and raise Yuuichi has her own.

To Tomoichi, she is a kind, beautiful, and proud mother. Of course, Misako also views Yuuichi as a lovely son.

While on the surface, Misako and Yuuichi have a friendly and loving mother son relationship, on the inside she is confused by the fact that she has developed feeling for him and the love she has for Yuuichi is different to that of a mother.

She is unaware of the fact that Yuuichi is a member of "mama club"...
