[CHROMA] Power LORA (Chainsaw Man)

Big thanks to the Chroma Discord for crash-coursing me on how to correctly train a LORA for this thing.

I love Chroma, but one thing it lacks compared to models like Illustrious and Pony is fandom knowledge, so I just decided to do it myself. The model doesn't have any fancy trigger word. Just prompt for Power in whatever prompt style you use and she should appear.
