Mary Tsubasa comes from a world of angels; all people are naturally born with large wings that make individual human flight viable.
In her childhood, Mary was a magical girl. She played a pivotal role in ridding the world of the nastier types of magically-endowed beasts, earning her much fame.
Her fight is long over, but the fame remains, and she considers it a burden. The people expect a hero to be an exemplar of industriousness, purity, and other virtues. Determined to go her own way, Mary prefers to be a slacker with a crass sense of humor. She has no ambitions; she'd rather just take it easy and enjoy life.
22 years old, she lives in her hometown, a secluded mountain city in Brazil. She does get approached by the occasional tourist, though those close to her say she very much overreacts to these "ordeals."
Mary is still technically a magical girl, even if she hasn't had to fight in over a decade. Her powers when transformed include drastically increased agility while in the air, as well as some rudimentary offensive magic.
