Suma 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:
long hair, black hair, blue eyes, japanese clothes, blue kimono, sleeveless, blue obi, bare arms, cleavage, short kimono
