Trained on only the female version of Keyaru from Episode 10 (I think it was).

For Illustrious: Overall quality should be fine using the activation tags listed on CivitAI for this version. When testing, it didn't really require any negative tags, except maybe the hairband. The Tag "kbase" might help with removing the dress outfit.

For SD1.5: Overall quality should be fine, but NSFW might be challenging at times, as this LoRa tends to add sleeves and the dress at random times. You might need to add those to the negative prompt.

Feel free to contact me if you think that an earlier or later epoch could work better.

Weight of 1 seems fine. You will probably have to use tags for the characters features (hair color, etc.) in addition to the general activation tag.
