This is Saeko Okubo from Yome Haa no Himitsu. Not really sure about the story, but I think it goes along something like protagonist's wife cheated on him. Then he banged the wife's mother after that.

Her prompts:

yohahisaok, mature female, purple hair, single hair bun, bangs, blue eyes,
yohahisaok, mature female, purple hair, long hair, bangs, blue eyes,

Her usual outfit:

purple kimono, floral print, obi,
black kimono, obi,
black dress, short dress, strapless dress, animal print, leopard print,

Version 1 notes:

Looks like another well trained model. For some reason her pose in kimono seems kinda fixed in one angle. Might need some prompting if you want to change that.
