Kise Yayoi attends Nanairogaoka Middle School as a second-year in class 2-2. Her civilian look features shoulder-length fluffy yellow hair, typically held by a white headband with orange gems on each side, and large round golden eyes. She usually wears a goldenrod pleated dress over a pale yellow long-sleeved blouse accented with frilly white details, dark gold Mary Jane shoes, and frilly white-cuffed socks. Her summer outfit switches to a white short-sleeved blouse layered over a ruffly pale yellow camisole, paired with pale denim shorts. She transforms into Cure Peace, embodying lightning and thunder. In this form, her hair brightens and lengthens significantly, styled in a fanned-out ponytail secured by twisted hair atop her head. A white tiara with a gold orb and swirled wing-shaped pieces adorns her head, complemented by round earrings. Her costume is a short yellow dress trimmed with gold scalloping, featuring a white feathered layer over puffy sleeves decorated with two gold spheres. A pale yellow bow centered by a gold Smile insignia medallion sits on her chest. She wears gold shorts beneath the skirt, a downward-pointing gold choker, white wrist pieces with goldenrod cuffs, and white ankle-length boots sporting yellow toes and goldenrod bows. A white bag with light yellow scalloped lining and a pastel pink bow hangs on her right hip. Personality-wise, Yayoi starts shy and modest, crying easily and keeping to herself. Recognition of her artistic potential by friends draws out a more passionate side. Confronting danger causes her to shed timidity, revealing inner strength. After forming friendships, she becomes more outgoing and bubbly, passionately embracing her Pretty Cure role. While retaining some crybaby tendencies, she demonstrates resilience protecting friends and making difficult decisions. She excels at sympathizing with others and honoring promises, though initial shyness prevents her from sharing her manga artwork. Key relationships include her bond with Hoshizora Miyuki, forged through understanding the challenges of being a new student. She maintains a close friendship with Hino Akane despite frequent teasing about her crybaby nature. Mutual admiration exists with Aoki Reika, who appreciates her artistic talents. Her family background includes a close relationship with her father, Kise Yuuichi, who found comfort in her presence during stressful times. In the film "Precure All Stars New Stage: Mirai no Tomodachi," Cure Peace joins the effort to locate and secure scattered fragments of the villain Fusion to prevent its resurgence. She allies with other Pretty Cure teams, including Smile and Suite, confronting Fusion-related threats across Yokohama. During a critical battle, she witnesses Cure Echo emerge, transforming in response to her bond with Fuu-chan, a fragment of Fusion. Cure Peace contributes her lightning-based abilities to the unified attack that ultimately defeats Fusion. Her combat abilities center on electrokinetic powers, initially manifesting through emotional surges like crying. She later learns to deliberately summon lightning from her hands, using techniques such as Peace Thunder to electrocute or paralyze foes and demonstrating the capacity to teleport through electrical currents. In advanced forms like Tiara Mode, her tiara evolves into an intricate gold crown, enhancing her role in group attacks such as Rainbow Healing. Princess Peace form adds a ruffled pastel yellow overlay to her costume with a rainbow-gradiented ribbon. Ultra Cure Peace form incorporates feathery pale yellow fabric across her chest and back like a cape, feathered wrist pieces with additional gems, wing-like boot cuffs, and functional white wings. Significant development occurs when she transforms into Cure Peace during a crisis, overcoming fear to protect friends. An April Fool's incident highlights her guilt sensitivity when a transfer school prank backfires, reinforcing her commitment to honesty. During a relay race, she battles self-doubt after overhearing criticism about her athletic skills but perseveres with team encouragement despite a last-place finish. In the final arc against the Bad End Kingdom, separated from teammates, her resolve solidifies upon reading heartfelt messages; this renews her determination to fulfill promises, showcasing her evolution from a timid artist to a resilient warrior.
