Player character from Mega Man ZX and her girlfriend/mission command. These two are very yuri for each other, and it’s not even a case of failing to adjust for the FeMC: The very intimate ending is exclusive to the Aile route, and Vent doesn’t even exist in the official audio drama Girls Bravo (where Aile and Prairie go on a date).

Illustrious actually does Aile base form pretty well without a LoRA, but its absolutely miserable for the other models.

I had to train this one twice since it didn't want to generate the pelvis parts on X or ZX as "greaves" till I added crotch plate. Added a bunch of data for the biometal when doing so since I had to retrain it anyways (doesn't seem to get the concept of holding them though).

Training data summary:
Human Aile: 3 official art (1 from X-Dive), 27 fanart.
Model X: 5 shots of ZX’s anime cutscenes (the ZX collection actually has high res ones based on the original master files instead of a upscale), an official art, and 4 fanart (low data set size, but most of the parts overlap with her base form or Model ZX so I figured it was worth a try)
Model ZX: 7(+3 in V2) shots of X-dive 3D model, 3 official art (2 from original game, one from X-Dive), a cutscene picture, 9 fanart
Prairie: 1 official art, 1 official manga page, 17 fanart.
+13 fanart with both base Aile and Praire
+20 biometal pictures (9 each solo+2 pics with both in it )
