Megane is love, megane is life.
Versions
Prototype: Trained on a toaster. Enough to get her likeness but not great, has some rough edges.
Leah from Pokemon Café Mix. Because of the low amount of images of her I had to supply the training with my own art and synthetic images, but it's generally usable. It's a bit hard to use, but works more often than not. Expert users should be able to manage. I'm trying to adapt to PonyXL training with my meager 1070, so this can be definitely improved if there's enough demand.
Default costume
pokeleah, blonde hair, ponytail, glasses, blue eyes, asymmetrical hair is enough to get her likeness. Hair will not always be asymmetrical, it struggles a bit with that.
Use red headwear, waist apron, black tights and maybe neckerchief and sneakers for her default costume. Add thighhighs to negatives if it keeps adding them. The apron is often drawn as a skirt, but it's cute, so I don't mind too much.
At times a mysterious handbag appears and I have no idea why, as none of the training images had one. Clearly, this is the work of a ghost or enemy stand.
Other costumes
On the other hand, applying various clothes and costumes is relatively easy. Add any element that sticks out to negatives and it should work out fine. It's also easy to insert eevees in the picture without extra loras, which is appropriate enough for the source material.
