Recently I've been reading Nekotete and I really liked the main female character. So here is a Lora for Mii-chan in both human and cat form.
How to use:
Humanform: humanform_mii, twintails, (optional black_hair or dark_hair)
Catform: catform_mii, cat_ears, cat_tail
Catgirl: "Add both humanform_mii and catform_mii in one prompt"
Additional info:
It mostly gets the colors right, but you can always add: Yellow_eyes and dark_hair to get it good every time.
Also because of the way the two imagesets are mixed, using humanform_mii with catform_mii and the trigger 'furry' will always end in a furry cat mii.
Adding: kitten, pet, or housecat will almost always add an extra cat to the image. I'd recommend not using those to keep her solo, unless you want to of course.
