Hibari Torii led the Torii Group yakuza clan as its matriarch, commanding significant respect through her leadership, beauty, and capability. After the clan's dissolution, she secured stable employment at a grocery store for herself and her former members, who transitioned to working there under her guidance. This shift from authority to customer service proved challenging, as she struggled to adapt to environments demanding deference rather than receiving it. Despite this adjustment, she maintained a dignified and graceful demeanor, though she could become visibly flustered when making mistakes. Her inherent leadership qualities continued to earn respect from colleagues and acquaintances, including the former yakuza member Tatsu, whom she encountered during a routine shopping trip.

Her appearance reflects traditional elegance: brown hair typically pinned back, brown eyes framed by thick lashes, and manicured nails often accentuated by classic red lip tint. She is commonly seen wearing a dark maroon kimono adorned with floral or plant motifs on the sleeves and hem, secured by a purple obi sash.

A later revealed aspect of her personal life is her fondness for cats. This fondness is seen when she visits a cat café and attempts needle felting to create a cat model, starting with the head. Her initial attempt was unsuccessful, though Tatsu later fixed the model despite his own inexperience with the craft.

In the live-action adaptation, her background incorporates additional elements. She is depicted as the widow of the Torii Group's patriarch and later enters a marital relationship with the former president of a different yakuza group, blending her original character with new narrative elements.
