This is Atsuko Maruyama from Itoshi no Manman.

Her prompts are:

itmaatma, mature female, long hair, blue hair, blue eyes,

Her usual outfit:

see-through, midriff, baseball cap, choker, denim, short shorts, bikini

Version 1 notes:

Seems to be a pretty well trained model. Due to how she was drawn in some angles, some images generated may give her really thicc thighs. There are a few pics from the dataset having her engaging in gangbangs so suggest to use the solo prompt if you want her to pose alone. Also suggest to use 29 steps and above, as a lot of text bubbles were cropped out from the dataset, if your steps is low you will see a lot of blank spaces generated.
