Mink is one of the two members of a self-proclaimed phantom thief duo that appears in the anime Brave Beats. She operates alongside her partner Tank, and the pair are depicted as comedic antagonists who frequently clash with the main characters, though they are rarely a serious threat. Mink is an adult woman with medium-length blonde hair, blue eyes, and a glamorous appearance, often seen wearing thigh-high boots, gloves, a ponytail, earrings, and makeup. She lives with Tank in a mansion filled with stolen goods, far removed from typical city life.

In terms of personality, Mink is talkative, strong-willed, and impatient. She presents herself as a noble, high-class woman who loves luxurious things and is not shy about using her charm and feminine wiles to get what she wants, especially from Tank. She can be quite demanding and assertive, but she also possesses poise and a flirtatious demeanor. Despite her self-centered tendencies, she has a genuine affection for Tank, and the two are portrayed as a devoted couple. Her confidence is matched by a tendency to act on impulse, often resulting in chaotic schemes that go awry.

Mink's primary motivation is to become the world's greatest phantom thief alongside Tank. She is driven by a desire to acquire anything that catches her fancy, and she often plans heists with a philosophy of being bold and flashy. However, her plans tend to be haphazard; she frequently adds unnecessary complications, such as stealing extra items or making sudden changes, which leads to unintended destruction. Despite these failures, she remains undeterred in her goal.

Within the story, Mink and Tank serve as recurring obstacles for the protagonists, particularly Hibiki Kazaguruma and his allies as they collect Dance Stones. The duo receives Odorings from the main antagonist Choreo, which allow them to power up when dancing together. Mink's primary dance style is jazz. In certain episodes, she and Tank play a more significant role by helping to open the sealed Dance Gate, sending the Brave Beats to the Dance World when a crisis arises.

Mink's most important relationship is with Tank, her partner and lover. The two are inseparable and function as a bumbling yet affectionate pair. Tank is a strong, mostly silent man who handles the physical labor, while Mink does most of the talking and planning. She relies on him to carry out her ideas, and he is fiercely loyal to her. Together, they form a comical contrast to the more serious heroes. There is little indication of development beyond their consistent dynamic, though they occasionally show a softer side when working together under pressure.

In terms of abilities, Mink does not possess supernatural powers on her own, but she is an agile dancer skilled in jazz. When she and Tank use the Odorings given by Choreo, they can execute impressive dance-based attacks, including a combined technique called Love-Love Super Chaos Dance. Her resourcefulness and persuasive skills are also notable, as she often manipulates situations to her advantage, even if her plans frequently backfire.
