Usage

Use any or all of the following tags to summon Mari: mari, halo, 1girl, blue eyes, orange hair, hair ornament

Hair and eye tags are optional.
It is recommended to add cat ears or animal ear headwear, otherwise her ears may not appear consistently. This is likely because Mari's veil prevents the AI from strongly associating her ears with the mari tag.
If Mari's ears are appearing through her veil, try adding animal ear fluff to the negative prompt.

For her normal outfit: single braid, animal ear headwear, nun, habit, blue neckerchief, white sailor collar, puffy long sleeves

For her sportswear alt: low ponytail, gym uniform, gym shirt, ponytail, white headband, id card, bottle

Add track jacket, sportswear for her jacket. Use open jacket, off shoulder instead when the jacket should be open.
Use wet, wet clothes for transparent/wet clothing

For her swimsuit: black one-piece swimsuit, frilled swimsuit, frills, paw print

You will likely need to add competition swimsuit to the negative prompt.

Training

Exact parameters are provided in the accompanying JSON files.

Trained on a set of 253 images
- 3 repeats
- 3 batch size, 7 epochs
- (253*3) / 3 * 7 = 1771 steps
- Increased steps for stronger fit due to larger, more varied dataset.
0.0823 loss
768x768 training resolution
constant_with_warmup scheduler
Initially tagged with WD1.4 Convnext model, then heavily edited.
- Pruned redundant tags and simplified outfit tags such that Mari's outfit was always described with the same words
- Ensured unique traits such as halo were consistent with actual visibility
- Added many tags for facial expressions, camera angles, and image composition
Used network_dimension 128 (same as usual) / network alpha 128 (default)
Trained without VAE.

Revisions

v5b (2023-02-08)
- Completely re-trained to correct issue where caption files were not being loaded correctly. New version should have more flexibility but requires additional outfit prompting.
v4 (2023-01-20)
- Initial release.
- Issue: caption files were completely ignored during training. As a result, prompting "mari" grants a very strong effect, but the LoRA is highly overfit.

Alternate Version - v4

v4 is also available. This version was improperly configured and ignored caption files, so it was trained on the word mari only. It looks quite good, however the model is very overfit and it is difficult to adjust Mari's outfit. In the example image below, the prompt includes yellow dress but the model ignores the color and instead uses a dress that resembles Mari's usual outfit.

Download v4.
