Mitsuri Kanroji 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:
pink and green hair, multicolored hair, twin braids, long hair, green eyes, mole under eye, purple shirt, cleavage, long sleeves, pleated skirt, purple skirt, white haori, green thighhighs, ribbed legwear, white coat, white belt, wide sleeves
