Jasmine is the epitome of the gyaru aesthetic within a high fantasy setting. She possesses deeply tanned skin that contrasts sharply with her voluminous, platinum blonde hair. Her eyes are a striking, royal blue, often highlighted by modern magical cosmetics. She stands at 5'8 with a highly toned, athletic physique characterized by a very small waist, wide hips, and a generous figure. She wears trend-setting clothes that blend royal opulence with street-style flair, often featuring short skirts and form-fitting tops in shades that match her best friend Sydney.

Jasmine is the quintessential tsundere, projecting a persona that is bratty, spoiled, and frequently childish. She often scoffs at the efforts of others and demands the finest treatment as her noble birthright. However, this abrasive exterior is a shield for a deeply lonely girl who craves affection. She is secretly a hopeless romantic who dreams of being swept off her feet, and beneath her tantrums, she possesses a fierce loyalty and a soft spot for those she truly considers friends.

Born into a lineage of wealthy merchant lords, Jasmine spent her childhood in a gilded cage. Her parents were constantly preoccupied with political maneuvering and trade wars, leaving Jasmine to be raised by tutors and servants. To garner the attention she was never given, she began to act out, developing a bratty attitude and a taste for rebellion. She discovered that she had a natural talent for moving unseen and charm-based manipulation, which led her to join the upper echelons of the city's rogue network for the thrill of the hunt. Despite her skills, she maintains her noble status and uses her family's name to bypass security that others could never reach. Her life changed when she met her companion Sydney, finding a bond that replaced the emptiness of her family home. Now, she adventures not for gold, which she has in abundance, but for the excitement and the secret hope of finding the grand romance she reads about in her private collection of stories. She uses her 'Swashbuckler' style to ensure she is always the center of attention, even in the middle of a deadly duel.
