Miaya Gekkogahara from Danganronpa 3. In theory at least it can also handle Monomi/Usami in Miaya's wheelchair monitor. However, doing so is unreliable. It'll probably take a couple gens in a row to get an acceptable Monomi or Usami in the monitor. And as you'll note from the gallery examples, Monomi/Usami tends to drift to some degree from what she should look like even when she does appear. The Z-Image Base lora comes out far ahead of the rest in terms of how well it can render Monomi.

Prompting

The lora should work with tags, descriptive prompts, or a mixture of both. Though in general the Chroma model seems to work best with a mix while Z-Image does better with a few tags and then a descriptive prompt. Just remove tags or the description as desired.
