A LoRA trained on all official outfits of Narmaya from Granblue Fantasy, trained using NAI as the base model at a network dim of 128 and resolution of 640 for 6 epochs. This is the second revision of the model, I didn't adjust the dataset but I did up the training resolution a bit and simplified the activation tags. This is also an earlier epoch so it should be a bit less burnt/overfitted.

Activation tags:
Character: narmaya
Base outfit: black dress, white coat
Summer Bikini: white bikini
Holiday: santa dress
Valentine: black sweater, apron
The Black Butterfly: black bikini, hood
Grand: red dress
Visions of Butterflies: bandages, purple kimono
Yukata: yukata

You can put other characters in these costumes as well, though it can be a bit finnicky, putting the LoRA strength lower will help.
Leaving white coat out of the base outfit gives you just the black dress thing part.
You can also remove the hood from the 'The Black Butterfly' costume by leaving the tag out.
