Neimi from Fire Emblem Sacred Stones.

Tested at 0.6-0.9 weight. Trigger word is neimi fe.

Prompt for default look: neimi fe, short hair, gloves, elbow gloves, pants, hood, fingerless gloves, headband, asymmetrical clothes, asymmetrical gloves.

The FEH splash screen effects like to make their way into the gens, so maybe either neg prompt "simple background, black background" or prompt a background for the AI to work with.

Kind of limited data, the asymetrical elements like the glove and the shoulder armor are very hard to get on the right place.
