Sora (Blue Archive)

ソラ (ブルーアーカイブ) / 소라 (블루 아카이브) / 空 (碧蓝档案)

Be forewarned that this LoRA is prone to generating NSFW results since Sora has an unusually high proportion of extremely lewd art. Use nsfw, naked apron etc in the negative prompt to prevent this.

Usage

Use any or all of the following tags to summon Sora: sora, halo, mini wings, white wings, two side up, blonde hair, forehead

For her usual outfit: blue apron, white shirt, (black pleated skirt:0.8)

  • If needed, you can also add off-shoulder, strap slip, bowtie, short sleeves
  • Sora's skirt is not visible in most training art. Consider adding black pleated skirt and negative prompt miniskirt, pencil skirt for more accuracy.

Sometimes her wings appear too high; low wings can help with this.

Weight 1 is suggested.
