I enjoy this concept so I thought I'd try to make a LoRA for it. You can interpret this as Belle having become a Beast herself, or the Beast being female, either way is of course fine. :)

This LoRA was trained on very few available images for this concept, so I apologize if it's overtrained or a bit rigid in what it can output. Most of the images seem to have been intended to be a female version of the Beast, which means they showed her wearing the blue ballroom coat with the poofy collar. You can usually escape this by putting coat and collar in negative and just strongly prompting for the clothes you do want.

You may want to mix this with other relevant LoRAs for the Beast or Belle at various strengths to draw in other concepts and styles.

The trigger word is "b3astb3ll3" and some of the most common associated concepts are "long hair, brown hair, brown fur, horns, fangs."

The strength that worked best for me was 0.9 but it's probably usable from 0.7 to 1.0.
