This LoRA has been trained using the Anything v4.5 model. It does a pretty good job at generating characters that look very much like May from Gundam Build Divers Re:Rise. Resemblance is actually very close if you the follow usage instructions.
The model has been trained using Kohya so you probably want to use it in the same way as you use other Kohya models. If you are Using A1111's Webui you want to move the file into the models>Lora directory. Make sure to use the corresponding trigger if you want her to have the correct hair color and get optimal results.
