Yukari Kotozume attends Ichigo Field High School as a second-year student, presenting a refined yet fickle personality prone to teasing others. Her self-centered tendencies often earn her the description of behaving "like a cat." She transforms into Cure Macaron, the Pretty Cure embodying beauty and excitement, drawing motifs from macarons and feline traits. Her signature expressions include "How Interesting" and "Fufufu..."

Visually, Yukari possesses long wavy purple hair and sharp purple eyes. She favors stylish attire in lilac, lavender, and purple, featuring trench coats, pencil skirts, and tailored dresses that shift seasonally—long light purple dresses in summer, cowl-neck sweaters with boots in winter. As Cure Macaron, her transformation includes a macaron-shaped hat with dark purple cat ears, a tail, raspberry earrings, and a purple dress with puffed sleeves plus a layered macaron-resembling skirt. She wears white opera gloves and boots with paw-like toes. Enhanced forms like Super Cure Macaron and A La Mode Style introduce lighter colors, wings, cape-like fabrics, and more elaborate ballgown silhouettes.

Her personality evolves significantly. Initially egotistical and manipulative, she demonstrates perceptiveness, such as detecting antagonist Rio's suspicious behavior. Her background involves childhood loneliness and frustration; constantly seeking passions, she felt trapped by others' perception of her as "perfect," leading to isolation. This struggle culminates in episode 29, where she confronts her younger self in a mirror world. She acknowledges she cannot erase sadness but finds strength through friendships and creating her own enjoyment, marking a turning point where she embraces vulnerability while valuing the "colorful world."

Relationships are integral to her development. She forms a bond with the earnest Usami Ichika and shares a complex dynamic with classmate Kenjou Akira. They initially clash due to opposing personalities—Yukari criticized Akira's selflessness, while Akira disliked her capriciousness—but develop mutual respect after witnessing each other's kindness and tenacity. Their relationship deepens romantically, highlighted by duets framed as love songs. She shares a unique connection with Three-star Kitty, a cat who exclusively allows her affection, and maintains a close, respectful bond with her grandmother, Kotozume Shino, who taught her etiquette. She also adores the fairy Pekorin, often gently stroking her.

In the movie *Kirakira☆Pretty Cure A La Mode: Crisply! The Memory of Mille-feuille!*, Yukari travels to Paris with the team for a sweets contest. Her perceptiveness proves critical when she deduces antagonist Cook is sabotaging contestants and manipulating pâtissier Jean-Pierre. When Cook unleashes experimental sweets as monsters and curses the Cures into animals opposing their themes, Yukari adapts strategically. Her resilience aids the team in overcoming curses via Miracle Lights, contributing to victory and restoring Paris.

Her name and theme carry symbolic weight: "Kotozume" combines "harp" (琴) and "claw" (爪), referencing cats, while "Yukari" (ゆかり) means "affinity" or "violet," aligning with her color scheme. Cure Macaron's namesake reflects the French dessert's variety and creativity, mirroring her multifaceted growth.
