Aoi Kanzaki from Demon Slayer / Kimetsu No Yaiba

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:

black hair, short twintails, blue eyes, butterfly hair ornament, hair ornament, blue shirt, blue pants, white apron
