Pet the CATGIRL. Do it now.

The cheeky Myarei from the manga The Daily Life of a Middle-Aged Online Shopper in Another World.

How to use
First, this isn't a perfectly stable LyCORIS. Myarei is mostly a gag character and as such she's either in the background making goofy faces or in the front making, well, goofy faces. Often with speech bubbles or other objects partially blocking her. I had to do a lot of fixing and editing including making intermediary models for refinement before I got a decently working dataset together so expect to have to fiddle a bit with prompts and strengths.
To prompt Myarei simply use the trigger word "fzbll" (fuzzball) along with "body fur". Her default outfit is tagged as "camisole, skirt, belt, lace-up boots".
For further prompt tips see the sample screenshots or the uploaded zip with training tags.

A couple of things to note:
Four fingers are normal, that's what she got in the manga.
While there are a few color shots in the dataset they're not enough to reliably get her hair and eyes right, use "blue hair" and "purple eyes" if you want to stay canonical.
The shine in her hair sometimes be interpreted as hieroglyphs by some models, if so add a hair tag like "shiny hair" to stabilize things.
Skipping "body fur" usually gives poor results so I recommend using it even for fully clothed prompting.
Recommended strength is anything from 0.5 to 1.0 depending on model and what you're trying to prompt where higher values makes it easier to prompt the default outfit and lower custom versions. To improve character consistency at lower levels add one or two catgirl tags like "cat ears".

MISC
Trained on NAI at 512 resolution on 60 images from the manga and a few color shots.
All images are raw txt2img upscaled, no inpainting or helper embeddings used for quality transparence, e.g. - things should look even better if you do.
The training was done on a small subset of images from the manga, as such the output of this LyCORIS is not an accurate representation neither in quality or style of the source material. Go buy the official release if you want the good stuff.
