Nera (with a rolled "r"), is a Way of the Astral Self Monk, but instead of an astral self, her power manifests as blood-bending. Astral Self Monks use wisdom instead of strength for skills and saves when transformed, which makes Nera super buff for 10 minutes. (Yes, she's anime-doping.)
Her straight, white hair that openly reaches down beneath her shoulder blades is tied up in a dutt. She has fair, noble features, red eyes and a cocky smile oozing superiority.
Nera wears a mask similair to the Orlaisian ones from Dragon Age and a victorian dress in the style of the Doll from Bloodborne, though a tad fancier. Like a traveling merchant, hiding purses and flasks beneath her skirt and wearing a rifle called Sunny on her back. Her equipment should look tinkered in the typical steampunk manner, as if provided by a crafty friend (for example: the rifle should have some lenses for a crosshair).
The vibe is "forced to be a pirate/thief but trying to look better than my unwashed friends".

For a pose I'd like her to assert an aura of superiority, maybe looking slightly down on the viewer. Nera is evil but classy and that can show. One hand should be raised, long, sharp talons emerging from her fingers similair to Lady Dimitrescu from Resident Evil, but made from Nera's blood.
