Esther Rosenthal from Toaru kagaku no accelerator
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
Prompts that I usually used:
blonde hair, medium hair, green eyes, hair ribbon, pink dress, red belt
