Akira Kenjō, also known as Cure Chocolat, attends Ichigo Field High School as a second-year student. She transfers to a neighborhood near Ichika Usami to be close to the hospital where her younger sister, Miku Kenjō, receives treatment for an undisclosed illness. Caring for Miku is her primary motivation, frequently bringing her chocolate to uplift her spirits and demonstrating deep devotion to her family.

Akira possesses a gentle yet resolute personality, often described as embodying a dog-like sense of loyalty and justice. She is rational, dependable, and protective of those close to her, frequently comforting others with phrases like "Are you okay?" and "There there." Despite consistent misidentification as a boy due to her boyish appearance and demeanor, she remains unbothered and occasionally displays a showy side. Her relationships drive her character development: she forms a strong bond with Ichika Usami after moving next door, often teasing her to ease nervousness. She also develops a notably close, potentially romantic connection with Yukari Kotozume (Cure Macaron) after initial clashes over their differing personalities, with their dynamic evolving through shared experiences.

As Cure Chocolat, she represents the Pretty Cure of "strength and love," themed around chocolate and dogs. Her transformation grants enhanced canine traits, including a heightened sense of smell for tracking enemies. Her appearance features red dog ears and a tail, a chocolate-themed top hat, cape, and paw-like boots. In battle, she wields chocolate-based weapons, including a sword, performing attacks like "Chocolat Aromase" and group techniques such as "Pretty Cure Animal Go Round." The Dog Chocolate serves as her Animal Sweet, the magical item enabling her transformation.

Key story arcs highlight her protective nature and resilience. Witnessing Ichika struggle against a Kirakiraru thief triggers her first transformation; her desire to protect homemade chocolate for Miku activates her Sweets Pact and Animal Sweet. In a critical confrontation, she sacrifices her own Kirakiraru to rescue Miku after the antagonist Julio drains her sister's energy, fueling her fury during the battle and leading to Julio's defeat, reinforcing her commitment to safeguarding loved ones. Another antagonist, Elisio, later exploits her devotion by kidnapping Miku and accusing her of prioritizing strangers over family, but she reaffirms her resolve to protect everyone without compromise.

In the film *Kirakira☆Pretty Cure A La Mode: Crispy! The Mille-feuille of Memories!*, she travels to Paris with the team for a patisserie competition. When Ciel (Cure Parfait) becomes emotionally distressed due to criticism from her mentor Jean-Pierre, Akira supports Yukari’s suggestion to give Ciel space, demonstrating her nuanced understanding. During the conflict against the antagonist Cook, Akira is temporarily turned into an animal opposing her dog motif but adapts alongside her teammates to confront the threat.

Her future, depicted in the series epilogue, sees her pursuing medical studies to become a nurse, continuing her lifelong dedication to caring for others; she wears her hair in a ponytail during this time. Her name carries thematic significance: "Kenjou" combines "ken" (sword or dog) and "jou" (castle), while "Akira" means "bright" or "clear," sometimes interpreted as "never give up"—a reflection of her tenacity.
