LoRA model for the AI VTuber Neuro-sama and her sister Evil Neuro, as well as #1 Tech VTuber Vedal (the turtle).

My contribution to The Swarm.

Trained on a mixture of official images, fanart, and lots and lots of VoD screencaps. May be just a bit biased towards her default pose, but you can fairly easily prompt for other things.

Recommended settings

• LoRA network weight 0.7-0.8 for Animagine XL v3, or very closely related models.

  • Depending on the relation of the checkpoint, higher weight may be needed.

• Trained on Animagine XL v3. May not work well on models not closely related to Animagine XL v3.

• I highly recommend using highres fix with this LoRA, as well as quality tags such as masterpiece, best quality, etc.

• If using with other LoRA or heavy style tags, weight may need to be lowered further if it is clashing.

• If you want to mount something on her head, dropping "ahoge" can help with consistency

• Her badges can be a bit inconsistent, especially the drone badge. Please adjust prompt weights and sampling method as needed.

• The legwear/bandaid often generates in the opposite configuration despite the training set having it the right way

• For her trademark gym bag prompt for "school bag"

• "demon horns" is in the training data for Evil, but only a little so I'm not sure how well it works

Neuro-sama (Halloween Dress)

1girl, neuro-sama, blue eyes,
light brown hair, ahoge, two side up, hair ribbon, red ribbon, heart hair ornament,
black dress, frilled dress, off-shoulder dress, bare shoulders, frilled choker, long sleeves, aqua bow, white buttons,

Evil Neuro (Halloween Dress)

1girl, evil neuro-sama, red eyes,
light brown hair, ahoge, two side up, hair ribbon, dark red ribbon, heart hair ornament,
black dress, frilled dress, off-shoulder dress, bare shoulders, frilled choker, long sleeves, red bow, red buttons,
black heart,
black socks, frilled socks, grey footwear, loafers,

Halloween Witch Hat

black headwear, lace-trimmed headwear, witch hat, hat ribbon, hat ribbon [aqua/dark red] color, yellow star \(symbol\),

Halloween Gym Bag

red halloween bucket, school bag, swirl lollipop, lollipop, candy wrapper, candy, chocolate bar, banana,

• The black heart patch on her knee is quite temperamental, due to the general prevalence of hearts in her design/fanart appearing everywhere

• The hat and gym bag are a bit less consistent than the rest of the outfit (they didn't appear in many vods).

• The model doesn't like to draw Vedal in the bag that much

Vedal & Rubber Duck

turtle, on head, animal on head,

rubber duck, on head, bird on head,

• It can also generate them not on Neuro's head if you drop those tags

• May cause the badges on the cardigan to go a little crazy sometimes

• You can prompt for expression "angry turtle" "turtle with one eye closed" etc. which might be needed as it will very likely leak in from elsewhere in the prompt otherwise

• Add "party hat" to get the birthday stream hat

Cat Mode

cat ears, cat tail, tail bow, :3,

• Tail lotto is real. I often get multiple tails, tails emerging from offscreen, bows without tails, etc.

• It's actually a bit better when doing angles not from the front

Special Expressions

heart-shaped pupils,
+_+,
tearing up,
nose blush,

*Frog hood, Christmas costume/hat, angel, pirate, teacher, etc. are currently not supported

I will probably update this model when her next new model debuts (assuming Vedal shows the whole thing on stream/posts).
