Akane Hino, a second-year student at Nanairogaoka Middle School, transforms into the fiery Cure Sunny. Hailing from Osaka, her speech carries a distinct Kansai flair, peppered with "uchi" for self-reference and playful interjections like "aka~n" to signal disapproval. Her family’s okonomiyaki restaurant serves as both workplace and culinary playground, where she tinkers with recipes alongside her younger brother Genki and shares boisterous, affectionate clashes with her father about tradition. A tomboy at heart, Akane’s posture radiates confidence—legs casually splayed when seated, stance firm when standing—yet she secretly adores whimsical charms, particularly gorillas, and cracks puns to lighten classroom moods. Fiercely protective of friends, she once leaped into battle unpowered to shield Cure Happy, an impulsive act that ignited her transformation. As Cure Sunny, she wields flames and raw strength, hurling boulders or cracking the earth with seismic strikes. Driven on the volleyball court, she aims to claim the ace spiker title, berating herself fiercely after missed plays. Initially dismissive of teammate Miyuki’s magical recruitment, she eventually harmonizes athletic drive with superhero duties, channeling volleyball flair into combat. Her signature Sunny Fire attack mimics a spike, launching fireballs later amplified in Sunny Fire Burning. Teamwork shines in joint techniques: Fire Shoot merges her flames with Cure March’s winds, while group finishers like Rainbow Healing erupt in dazzling unison during upgraded forms. Though she ribs timid classmates like Yayoi, mutual admiration anchors these bonds. A friendly rivalry with Cure March evolves into steadfast camaraderie through shared battles. Post-series novels reveal a lingering crush on exchange student Brian Taylor, sustained through letters a decade after his departure. Her transformations mirror growing power: initial orange-themed gear sports feathered sleeves and a perky bun, while upgrades like Princess Sunny drape her in gold accents, flowing locks, and celestial halos. Ultra Cure Sunny adds wings and iridescent hues, unlocking barriers and purification blasts showcased in crossover films. Names anchor her essence—"Hino" (sun/field) and "Akane" (sunset crimson)—tying her to fire and solar motifs. Her journey weaves personal ambition with collective duty, maturing from a skeptic of heroism to a crisis leader who bridges fiery independence with unshakable teamwork.
