This LoRA will generate Sayaka Miki, it's been pretty good about getting her outfit correct, but sometimes it's a tad lewd, so you may need to neg prompt for that if her skirt is too short.

Triggered by: Sayaka Miki

If she is generating without her cape, prompting for "cape" should fix it. Not sure why it excludes it sometimes.

I've had success with weight 1, but you may need to adjust to 1.2 or higher. 1 tends to produce passable results, but there may be small variations on her outfit. 1.2 has shown good results with getting more details correct without effecting the overall image.
Models used in the previews are Salute mix, Ivory, and Aniflat. I did not try on a model geared toward photorealism.

You can remix her clothing by prompting for a weighted design, such as (girl wearing teal kimono:1.2), I have attached an example of what that outcome looks like.

Enjoy!
