Monster Hunter Monster Girls - Nu Udra: Now The Black Flame can be a cute or sexy monster girl! Also seems to work for the non-personified giant cephalopod and might work for monster boys and furries. The training data is entirely monster girls and the monster itself though, so no promises on those.
Trigger words are a bit different this time because I'm testing a slight different tagging approach.
Anthropomorphized: "Nu Udra, personification" then add monster girl/monster boy as desired.
Monster "Nu Udra, cephalopod, monster, kaiju"
IL-v1: First version for Illustrious. This came out decently well, so I'm not labeling it as an alpha.
PDXL-v1: First version for Pony, generally has the same triggers as Illustrious, but to get the monster you need to add "monster girl, anthro" to the negatives. Doesn't like making personified Nu Udra a scylla without additional LoRAs. Sometimes needs "greyscale" added to the negatives.
