Kaya Velasco from Warframe 1999, Illustrious version. Works for both SFW/NSFW

Trained on the standard, original look, but also on some custom fashion frame to hopefully make it good to use with different kinds of colors and clothing.

BEST PRACTICE:
Use with ADetailer to clean up face weirdness, it works pretty well. You will want to upscale the image, as the small standard resolutions give out really bad results. Even with a basic upscaler at 2x you'll get some pretty good results. You can set the steps of the original image generation to a lower number, and the steps in the upscaler to a higher number to save some time for no real difference in quality (for this model, I use 20/30 split)

STANDARD PROMPT:

realistic, kaya, 1girl, hair bun, classic outfit, pink hair, pink eyes, pink turtleneck

ALTERNATIVE PROMPT:

realistic, kaya, 1girl, hair bun, black turtleneck, white hair, red eyes, sleevless

MAIN KEYWORDS:

• kaya - self-explanatory

• hair bun - put in every single prompt, should hopefully make it so that other hair styles ca be used

• (color) turtleneck - highlighted the turtleneck both to facilitate changing it's color, and to potentially skip it if another outfit is desired, make sure to mention it in pink if you want her default

• (color) hair, (color) eyes - they were used in every prompt in training, make sure you mention them as pink if you want her default

• classic look / nova look / classic outfit / nova outfit - all used in every single prompt which didn't have visual modifications to the skin, make sure to use if you want just classic Kaya
  

OTHER KEYWORDS:

• gemini emote / picture emote / photo emote / gemini gesture / picture gesture / photo gesture - I've added a multitude of screenshots of Kaya doing her emote gesture and all those pictures were tagged with all the above tags, seems a bit difficult to get to work but you can try

• earrings / jewelry - present in almost all pictures, referring to her various facial knick-knacks

• reactor / chest reactor - should add her chest reactors, have not tested it but there were multiple screenshots with the reactors that were all tagged with both

• chest emblem - from a few pictures with the ember heirloom sigil on the front

• wet - pictures with Garuda's blood sigil colored to grey

• sleeveless - used on pictures where I used a color tone on Kaya that made her arms look more human

• stickers - used on all pictures where her thigh pouches with the stickers were present

• boots - used on most pictures with her boots present, hoping that it will make the generator be able to skip them if desired

• infestation - used on some images where her neck infestation was particularly visible

• blue energy - used on a lot of images that had a lot of VFX from emotes, you'll get varying results with it but there's quite a few references to it

• snow / snowing - I liked a lot of the expressions from Velemir's emotes so a lot of ice themed pictures made it in, should make it easy to go wild on an Xmas themeing

• silence gesture / finger pointing up - used the Mirage Oneiro idle quite a bit so there's a few references to the stance there
