Se-Mi Han from Solo leveling / Ore dake Level Up na Ken
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 0.9 works great, though you can adjust the strength as you prefer.
Prompts I usually used:
Se-Mi Han, semi_han_sl, long hair, purple hair, long braid, purple braid, dark green eyes, dark purple dress, multicolored capelet, purple capelet, long sleeves, white gloves, earring, high collar,
