I figured I might as well get a lora going for Leia, the mermaid bachelorette from Harvest Moon DS. The dataset is kinda limited since there's rather few images of her to choose from, and all the official art of her are rather chibi style, which essentially forced me to use fanart in order to diversify the dataset enough to allow users to generate all kinds of content with her. Either way, I believe the end result should be good, as long as you use appropriate tagging.

Trigger word: hmLeia

Appearance: green hair, medium hair, bangs, purple eyes, shell hair ornament, monster girl, mermaid, mermaid tail, orange tail, gradient tail

Clothes: bandeau, midriff, bare shoulders, pearls, belly chain, arm ribbon

After some testing with the model to ensure how it works with correct tagging and negatives, I recommend you use the model at 0.8 strength for best effect.
