Emily, known as Glitter Lucky when transformed, is a key warrior defending against despair. A transfer student initially nervous during introductions, she quickly bonds with classmates who become fellow fighters. She possesses light skin, magenta eyes, and distinctive magenta hair styled in cone-shaped buns secured with yellow bows. Her everyday outfit consists of a pale pink long-sleeved shirt under a pale yellow and fuchsia vest, a layered pink and magenta mini skirt, white tights with pink stripes, and pink sneakers. Seasonal variations include a ruffled short-sleeved pink shirt with a magenta ribbon, denim capris, and strapped fuchsia sandals.
Her transformation into Glitter Lucky follows an encounter with Candy, a fairy from Jubiland, and witnessing an attack by Ulric. Accepting the warrior call, she metamorphoses within a column of pink light. As Glitter Lucky, she wears a light pink short dress featuring a prominent magenta bow with the Glitter Force symbol on the chest, white ruffled sleeves adorned with pink beads, and a light pink skirt with hot pink trim. Her attire includes magenta bike shorts, white boots with light pink cuffs and magenta ribbons, white wrist cuffs with similar ribbons, and a pink choker. Her hair restyles into low ponytails with strands often sticking out, topped with a white tiara featuring a pink bead and small wings. Advanced forms include Tiara Mode, where her tiara becomes a golden crown with a dangling heart charm, and Princess Mode, adding a light pink overlay dress, a halo, and golden ribbon earrings. Royale Mode introduces a new golden tiara with wing motifs and wing accents on her dress.
Emily exhibits a bright, energetic, and overwhelmingly optimistic personality. She finds joy in small things like sweet treats and openly expresses affection for friends and Candy. Her love for fairy tales fuels her imagination and sense of wonder, leading to playful pretend scenarios. This enthusiasm sometimes causes physical clumsiness. Despite her cheerful demeanor, she initially struggles with fear during battles, attempting to hide or flee rather than confront enemies. Early on, she questions her decision to become a warrior, lacking confidence. However, she gradually develops courage and leadership skills, rallying her team with increasing reliability while maintaining her enthusiasm. Her catchphrase is "Another happy ending!".
Key episodes illustrate her growth. A body-swap incident caused by Brooha's magic rings leads to frustration but deepens empathy for Candy. An April Fool's prank involving Lily's fake school transfer plan triggers panic, demonstrating fierce loyalty. A shrinking mishap induced when Candy strikes her with a magic mallet forces navigating a giant world. Her leadership faces a test during a school trip to the Asian-Pacific Expo when a fortune predicts bad luck; losing her Glitter Pact mid-battle results in temporary defeat, a failure she learns from with team support. For Mother's Day, feelings of inadequacy lead her to craft a necklace, later recovered from an enemy attack.
Relationships define her journey. She recruits teammates: Kelsey after supporting volleyball, Lily by defending her during a poster contest setback, April through helping with her siblings during a babysitting crisis, and Chloe by assisting with a puppet show project. Candy serves as her constant companion; their bond is evident when Emily reassures Candy after an argument. She deeply values her mother, striving to create a meaningful gift, and credits her grandmother with teaching her to smile during shy childhood, advice that helped overcome timidity. A childhood encounter with a character named Nico from a storybook inspired her appreciation for smiles.
Her combat abilities evolve. Initial attacks rely on physical maneuvers, often accidental. She later masters Sparkle Storm, a directed energy attack requiring concentrated "glitter spirit," first used to defeat Ulric's Buffoon. The discovery of Tiara Mode enhances her capabilities, enabling powerful group attacks like Tiara Mode Torrent. Her Glitter Pact serves as both a transformation device and an energy channel.
Notable adventures include discovering the Library of Legends, a magical interdimensional archive accessed through bookshelves, where the team learns their history and devises their group catchphrase: "Shining bright, here comes the Glitter Force!". She identifies a woodland area near her former home as the team's secret hideout, inspired by friendship bonds in "Anne of Green Gables".
