"Is this person really a priestess?" ~Someone on a Jewel Princess wiki. For appearance:

HimekawaJP, double hair cone, purple eyes, long hair,

For normal outfit:

HimekawaDef, hair ornament, magatama, hakama, cleavage, ribbon, detached sleeves, wide sleeves, short hakama skirt, white thighhighs, sandals,

For her maid appearance

black maid bikini, maid headdress, magatama necklace, front-tie bikini, long white gloves, black miniskirt, waist apron, white thighhighs, mary janes,

use "single staff" for her staff but it might appear even if you don't prompt for it. In Pony It might generate in greyscale or monochrome with her maid outfit so add those to negatives. In illustrious, it greatly favors Japanese architecture. If you have trouble with her double hair cone, try "double bun" in addition or instead of double hair cone. Sorry if the example images are a bit uninspired.
