Recommended weight 0.8. Trigger viv.

-- Identity (baked into the trigger) -- pink→purple gradient twintails, ahoge, blue eyes, a fang, and a black choker. She's a beauty / makeup-themed idol.

-- Trademark outfit (add for the canonical look) -- white cropped shirt with a black bra worn OVER the shirt (bra over clothes), shoulder cutout, purple detached sleeves / arm warmers, black shorts, black thighhighs, belt. Add holding makeup brush, lipstick tube, cosmetics, pink nails for her signature beauty-idol theme.

-- Style note (IMPORTANT) -- For clean anime shading (not 3D / semi-real skin), put anti-realistic terms in the NEGATIVE prompt: realistic, 3d, photorealistic, shiny skin, oiled body, semi-realistic, render.

-- NSFW -- Undresses cleanly; the twintails / ahoge / fang persist through explicit scenes.

Tested checkpoints

• ✅ waiIllustriousSDXL_v170 (trained base)

• 🔍 Other Illustrious XL fine-tunes (untested; start weight 0.6-0.8)

• ❌ Pony / SDXL base (architecture mismatch, untested)

Caveats

• Keep bra over clothes for her canonical idol look (the black bra sits on top of the white shirt).

• On checkpoints other than the training base, the recommended weight shifts (try 0.6-0.9).
