A fairly simple lora that I just trained on danbooru information. These older games tend to not be represented well enough on there for illustrious to really pick up on them by default. So this acts as a crutch of sort to push up their strength.
This lora should cover the majority of the main characters from Shin Megami Tensei If... , Persona 1, and both Persona 2 games. Not all by any means, but a solid chunk of them. Sadly, no Otsuki. There's a few instances of hee-ho-kun in the dataset, but a bit too sparse to be usable. Annoyingly, it also tends to do a poor job of rendering the SMT If comps. The comp's tag is comp_(megami_tensei) but so far in my testing it seems extremely unreliable.
I've included a lot of generation examples, but when in dobut check danbooru to see if one you're looking for is on there. If it is then there's a good chance this lora should be able to handle the character.
You can push the style closer to the official style from the games with either of these tags:
official_art
kazuma_kaneko, official_art
Here's a list of the characters that seem to, for the most part, work fairly well.
