Yuki Terai.

Yuki Terai is one of the earliest virtual idols, certainly that I've ever heard of.

This PONY LoRA is trained on mostly images from her official artbook, the booklet that came with her first album, and images created from many digital artists in the mid-2000s with DAZ Poser for which Yuki Terai was an available model.

You want to be generating images in at least 1024x768 or 1024x1024. Weight should be 0.8-1.0. Good looking results using an upscaler on 0.7. Feel free to copy from and adjust my generation prompts, have a play around with it.

Trained on SFW and NSFW, can generate both.
