This is a DoRA, not your typically made LoRA. A1111 v1.9.0 and up is required to use this. Forge users must download two files, which can be found here. Go to stable-diffusion-webui\ldm_patched\modules and replace the files there.

Weight: 1.0

Trigger + Appearance: omava, monster girl, harpy, black wings, feathered wings, winged arms, bird legs, talons, ahoge, hairclip

Default Outfit: mask on head, pink jacket, jacket partially removed, partially unzipped, black tank top, turtleneck, yoga pants, bare shoulders

Add streaked hair, black hair, pink hair and pink eyes if necessary.

The results of your generations are dependent on the additional LoRAs, weights, and models you use, so it may not work or come out as consistent as my sample images.
