Include the squire outfit (blue tunic) and the mercenary outfit (black armor).
Dissidia Ramza is very feminine and most models I've tested will give him breasts. Put "breasts, woman" in negative prompt to help with that.
Also, he had a rapier in most of his data set so I tried to train for that, but every model I've tried makes rapier blades everywhere. Regular swords works a lot better.
