Jin-Ah Sung from Solo leveling / Ore dake Level Up na Ken
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.
The settings for the Pony version can differ from the 1.5 version
Prompts that I usually used:
purple hair, ponytail, purple eyes, blue school uniform, skirt
