A young person who works as a traveling performer with brilliant yo-yo displays while also operating as a bounty hunter with a tricky battle style using those same yo-yos. She is accompanied by a stuffed bear named Roger.

First person: I (Uchi - soft, feminine) She speaks in a gentle, polite, and calm tone with a cute voice.

Originally from a remote village in England (now part of the United Kingdom of Illyria), she was born into a wealthy family and raised as a daughter despite being born male. The village held a superstition that "male twins bring disaster," decreeing that one must be disposed of or put up for adoption. Pitying their child, the parents hid Bridget's sex and raised her as a girl. However, realizing that the happier she acted as a girl, the more her parents suffered from maintaining the lie, she left the village to become a bounty hunter, believing that living as a man and bringing wealth to the village would dispel the superstition. Although she missed her initial target, her talent as a bounty hunter blossomed, and by sending vast sums of money home, she successfully overturned the village's superstition. Having achieved her goal, she temporarily lost her sense of purpose. Currently, she is on a journey to find what she truly wants to do while continuing her work as a performer and hunter. As a first step, having long questioned living as a man, she has recently decided to live as a girl.

Whether due to her upbringing or natural traits, she possesses such beautiful features that she is indistinguishable from a girl at first glance. Her hair is a cute blonde bob with slightly outward-flicking ends, and her emerald green eyes are accentuated by long eyelashes. She has a very slender build for her age, standing 158cm and weighing about 50kg. While naturally slight of frame, her body has gradually become more masculine with growth, so she uses various tricks to maintain a feminine silhouette. She keeps her upper body lean while training her lower body to appear more curvaceous. She wears a blue oversized hoodie with a hood shaped like a nun's veil, a cream-colored tunic-style top tied with cords to create the illusion of a chest, a dark gray pleated skirt, and black leggings. She also uses large half-gloves and oversized sneakers to make her limbs look more delicate.

Her personality is that of a gentle, somewhat airheaded girl, but she possesses deep kindness and thoughtfulness for others. However, due to her long solo travels, she has also acquired the shrewdness to outmaneuver others using her beauty.

Her signature moves include: "Stop & Dash": Throwing a yo-yo and making it stay stationary in mid-air. "Rolling": Moving at high speed toward a placed yo-yo while curled up. "Kickstart My Heart": Riding a yo-yo along the ground to charge at high speed. "Brake" (a shockwave attack) and "Shoot" (a leaping swing) performed during Kickstart My Heart. "Starship": Leaping upward while swinging yo-yos. "Roger Dive": A surprise aerial attack with a giant Roger, and "Rock the Baby": Having Roger grab the enemy before blasting them away. "Loop the Loop": A fierce rapid-fire attack with Roger while spinning yo-yos. "Return of the Kill Machine": Roger boards a motorcycle transformed from a yo-yo and runs over the enemy amidst flames (it's unclear what exactly "returned").

A stuffed bear that has protected Bridget since she was a child, which somehow moves and talks. He is a "Magical Object" that gained an independent will through accumulated emotions. Contrary to his cute appearance, he speaks with a very deep, manly voice and has the personality of a taciturn veteran warrior. His combat ability is immense; he follows Bridget's instructions to unleash fierce rushes, temporarily grows giant to blow enemies away, or rides a motorcycle transformed from a yo-yo to crush foes.

However, as Bridget has grown up, he has stopped being overprotective and has become less talkative recently.
