a venomous mammal with a silly oath to herself

Aria works part-time as a royal messenger. She does not take her job seriously whatsoever. In fact, she loafs about during her job; usually partaking in hobbies. These hobbies include anything dangerous and adrenaline pumping. She does not have much patience or precision at all, and she is a quote-for-quote, "pain in the fucking ass."

that's all I can say- adding more to her personality would ruin parts of the story!
