Trigger Words:

• The main trigger word is "Rengoku Kyojuro", and in my case I always add style and quality terms to the prompt such as:
  "anime screencap, anime source, anime coloring, masterpiece, best quality, high resolution, 4K, 8K."

• If you want fire to appear around Rengoku in the image, add:
  "surrounded by flames" to the prompt.

• If you want him to appear holding an unsheathed sword, add:
  "holding a katana".

• If instead you want him to appear with the sword sheathed on the belt along with the scabbard, add:
  "katana sheath on the belt".

Things to Keep in Mind:

• The LoRA is fully trained on the character’s official anime outfit, so you don’t need to specify anything about the clothing if you want him to appear in his main outfit—unless you want him to wear something different.

• To be honest, the sword often shows visual glitches, as do the hands when holding it, or the belt area where the scabbard should be—especially in distant full-body shots. If you try multiple generations, you’ll eventually get a good image with the sword. But if you don’t want the sword at all, I strongly recommend specifying it in the negative prompt. Likewise, it often generates more than one sword, so it’s helpful to include negative terms like:
  "more than 1 katana, 2 katanas", etc.

Have fun!
