Illustrious update*: New trigger, bigger dataset, some of her new looks added, overall larger variety and better response, the tags should be close to her PONY version with slightly more detail, check the examples if you need more info.
Recommended weight: 0.8. Default look model as in her first appearence, pretty straightfoward and should give you no problems that I'm aware of. Here are the tags:
Character:
1girl, solo, long hair, blunt bangs, streaked hair, blue hair, pink hair, blue eyes, mole under eye
Outfit:
borutoeida, earrings, bracelets, white shirt, long sleeves, high-waisted shorts
