Falling through a time-rift, your character ends up in pre-historic times. Will they survive? What awaits them?
This LyCORIS was trained on 100+ images that fit the theme including NSFW content. The outcome seems pretty good to me. Sample images aren't upscaled but you can get better results if you use the various upscalers. But let me know if you run into any problems. Otherwise, go ahead and generate your favorite characters in some pre-modern times.
Trigger words are: StoneAgeCh, StoneAgeChEro (for NSFW)
Additional words that may help: yellow clothing, brown clothing, loincloth, animal print, outdoors, torn clothes,
Recommended Strength: 0.6 - 0.9
