This is Hitomi Ayase from Dear My Mother, as you can see her character design is very similar to Scarlet Desire. But since this is technically a different series and I am training with a totally different data set, I am treating this as two different characters.

Her prompts are:

dmmhiay, mature female, long hair, red hair, blue eyes,

No usual outfit again. In fact most of the souce material is of her totally nude.
