A fairly basic lora trained on most of the Devil Survivor images from Danbooru with a few additions from other games in the franchise to try beefing up demons that were present but underrepresented in the initial dataset and a few extras like Sophia from Persona 5 Strikers to try normalizing for style. I'd suggest just experimenting with it a bit if you like it. The general idea was just to strengthen elements that were probably present in the model's training data but underrepresented to the point where it wasn't really usable. Think of it as a specialized megaten crutch.
