Shinobu Kocho from Demon Slayer / Kimetsu No Yaiba
When I tested it some different checkpoint and LORA's it seemed to work well with this LORA.
LORA weight 0.8 works great, but feel free to adjust the strength to your liking.
Prompts that I usually used:
black hair, purple hair, short hair, multicolored hair, purple eyes, empty eyes, japanese clothes, purple shirt, purple pants, white coat, butterfly print, butterfly hair ornament, hair ornament
