It is a lora meant to generate realistic videos of Ruby Rose from the anime series RWBY.

Sample prompt:

A high-definition video of Ruby Rose (RWBY). She is lifting her black crop top, exposing her naked breasts and nipples. Titty drop, flashing her breasts. She has gorgeous silver eyes. She is in her bedroom. There is a bed in the background. The camera is held steadily and has focus on her body.

I also recommend you generate at 768 x 1344.

There is a also a photo version of this lora trained on the same dataset: https://civitai.com/models/1142326/ruby-rose-rwby

The difference is that the Flux variant is of much higher quality (at least for the moment). Once Kohya introduces training for Hunyuan, that will change.
