LoRA for the Ghost Girl from Mon-Musu Quest!.
I could only get 5 images for the training set, so I have no clue if this will work well for you, but give it a go.
Prompt:

• mmghostgirl, black hair, long hair, pale skin, red eyes, armless, big breasts, purple nipples, black slime body, floating hands

• Toss ((arms, legs)) into the negative prompt as well

Notes:

• I had to crank the LoRA weight up to 1.4 for the swoopy part of her hair to appear in my usual style so you may need to do the same

• Arms may still show up regardless of what you prompt against them
