This is a lora meant to create a variety of asari characters. This is a model trained with text encoder on about 30/70 SFW/NSFW art, primarily of realistic nature. The lora is not particularly horny, surprisingly, but do consider the origins when tagging.
Separate anime release is available as well. https://civitai.com/models/20081/asari-diffusion-anime
Tags: "Asari" is the main trigger. This lora is trained to reproduce blue, green and purple skin with quite a few possible variations of color (but see issues, below). Other tags as appropriate for your model, nothing special. Since the model is trained on a variety of nsfw art, nude pictures work with obvious tags. Have not tried anything hardcore, but should work with an appropriate base model.
Tagging clothes description seems to be enough to avoid nudity.
The model has not been trained to recognize any particual Mass Effect characters, but you will sometimes see Liara's face.
Issues: Sadly, skin color tags often bleed into other parts of the shot, I was not able to figure out many ways around it other than to tag carefully or not tag the skin at all and rely on random. It happens less with blue_skin.
