Sunohara Kokona (Blue Archive)

Usage

Use any or all of these tags to summon Kokona: 1girl, halo, animal ears, orange eyes, long hair, grey hair She really doesn't need many, just 1girl, halo is enough to summon an instantly recognizable version of her. The model may be a little overtrained but it looks good.

For her normal outfit: china dress, vertical-striped dress, white skirt, frilled skirt, off-shoulder, jacket

Somewhat frequently, a strange, mysterious man in a black suit likes to appear out-of-frame beside her. You can shoo him away with 1boy in the negative prompt. Not sure why this happens as there was nothing like it in the training data.

The AI is generally pretty good at picturing her, but it really struggles with her pout. Try various combinations of pout, :t, pouting and negative prompt wavy mouth to try to get it to appear correctly, or just use img2img without the LoRA. It seems to be related to the LoRA since vanilla NAI can do pouting just fine.

Her stamp is in the training data and it sorta knows what it is but is probably too small to be recognized by the AI.

You can add or ignore kokona, blue archive; while they were in her captions, their effects aren't especially strong.

Weights close to 1 work well with her, she's very cooperative.
