For completion's sake here I add the 3rd Tendou sister. Both reviled and loved by many. To me she is kind of meh. But If you are going for sisters you might as well get the full set. Nabiki's dataset turned out to be a mix and match and had to really dig to get a proper-ish one. On the other hand Ranma, Akane, Shampoo and even Kasumi were much more easy.
Don't you get angry when your hairstyle subsumes your personality? Well it happened to my LORA. It refuses to trigger unless you add short_hair. Regardless... Pay attention to the suggested prompt. I might do a V2 version later with more tag pruning.
I got nice results with: masterpiece, best_quality, highres, TendouNabiki, short_hair, bangs, large_breasts, brown_hair, brown_eyes, <lora:TendouNabiki:.65>, solo,
Her special outfits are:
FurinkanUniform

Her Furinkan uniform seems to like getting a bow or ribbon. That's odd as there is no such a thing in the dataset. I would recommend to add it to the negatives when generating her furinkan uniform.
Her hair and eye color might color change a bit so add brown_hair and brown_eyes if you want to stop them from drifting.
Seems to be tolerant through the whole spectrum but gets more cartoonish the closer you get to weight 1. It seems to reflect more her canon appearance at around .6 to .7.
