Milly from Toaru ossan no VRMMO Katsudouki / A Playthrough of a Certain Dude's VRMMO Life
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:
long white dress, blue trim, long hair, vibrant blue hair, white hairclip, blue eyes
