Images trained on game official art and ingame screenshots. Note the "cat ears" in the negative prompt. I only had one training image where Claire had cat ears, yet it spontaneously shows up more often than not in the generated images. Might be a positive for some people. It is necessary to add "pink hair" to the prompt to get the Lightning look.
