Albis from That Time I Got Reincarnated as a Slime / Tensei shitara Slime Datta Ken
When I tested it some different checkpoint and LORA's it seemed to work well with this LORA.
LORA weight 0.7 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
The Naga variant might have few problems generating the snake body
Prompts that I usually used:
long hair, black hair, yellow hair streaks, white and purple dress, purple capelet, long sleeves, green eyes, gold necklace
