Tayuya from Naruto
Keep in mind that settings may vary slightly between different versions. See below for more details.
When I tested this with different checkpoints and LoRAs, it seemed to work quite well.
Pony:
A LoRA weight of 0.8 works great, though you can adjust the strength as you prefer.
Prompts I usually used:
Human:
long hair, red hair, brown eyes, black hat, tan tunic, purple rope, black arm warmers, black shorts, aTayuya
Demon:
long hair, red hair, yellow eyes, black sclera, facial markings, dark skin, white horns, bTayuya, tan tunic, purple rope, black arm warmers, black shorts
