Aihara Akito Manga

Ayano-san is a beautiful housewife with a son, Yuusei, who doesn't seem to approve of her carefree ways. Always smiling and well-meaning, Ayano-san still finds a way to make herself an object of curiosity and appreciation by passing people."Bimajyo" (literally beautiful witch) is a term apparently used in Japan to describe a woman older than 35 or so who has retained her great beauty, almost as if by magic. So it doesn't mean she's a witch or the series will pivot to that genre in the future.
