Description
Natalie Miller emerged from a fragment of Princess Marie Angelica's heart, specifically the portion representing love for her kingdom. This occurred when the princess sundered her heart to separate noble intentions from paternal affection during a terminal illness crisis involving the misuse of the Golden Crown of Wisdom, which transformed the king into King Mercenare. Sent to Earth as an infant, she was discovered crying in the woods by an elderly woman who became her adoptive grandmother. Threatened by a distain, the infant Natalie emitted light and rapidly aged to approximately ten years. Raised solely by her grandmother, she learned traditional arts like tea ceremony preparation, integrating it into her daily routine.

Physically, Natalie appears as the youngest and shortest in her group, possessing burgundy eyes and long brown hair typically styled with bangs pulled back. Her standard attire is a sleeveless red dress with white stripes at the skirt hem, a white neckline featuring a central ribbon, magenta sneakers, and white socks. In cold weather, she wears a red jacket with a white collar, a black skirt, and burgundy boots. Transforming into Glitter Ace brings dramatic changes: she grows significantly taller than her teammates, develops bright red, voluminous hair styled in thick curls, and her eyes shift to magenta. Her transformation outfit is a red and black scalloped dress layered under a white jacket with red detailing and pale pink cuffs. Gold accessories include a pointed hairpiece with a winged bow, earrings, a necklace, and a chest emblem, completed by white feathered wrist cuffs, red straps, and knee-length boots.

Her personality blends composure, strictness, and wisdom beyond her years, sometimes perceived as bossiness or leading to unintentionally hurtful remarks when enforcing rules. Despite this rigidity, she harbors a deep appreciation for culinary pleasures, especially sweets like peach rolls, Sebastian’s cakes, and anmitsu, which she describes vividly. This duality reflects her struggle to balance lofty responsibilities with human vulnerabilities. Initially viewing fellow warriors Maya, Rachel, Clara, and Mackenzie as inadequate allies, she adopts a stern, critical stance to strengthen them for their mission to save Splendorius. Over time, she softens, developing genuine camaraderie and recognizing them as valued teammates.

Her relationships stem from her mystical origins. Princess Marie Angelica is her creator, while Regina, born from the evil half of Marie’s heart, functions as a twin sister or counterpart. Dina, originating from Marie’s soul after its transformation into an egg, is regarded as a younger sister figure; Natalie feels protective of her even before understanding their connection. Her grandmother remains her sole familial anchor, having nurtured her and imparted cultural practices like tea ceremonies.

Transformation into Glitter Ace requires collaboration with Dina, who summons a device containing Royal Crystals and a stylus. The process involves inserting a Glitter Charm, tapping the crystals, and applying "shades of victory" as eye shadow. During transformation, engulfed in fire, Natalie declares phrases like "Feel the fiery energy!" and "A for absolutely fabulous!", culminating in her aged-up form. Her primary attack, Ace Shot, utilizes a Glitter Sparkle Stick and varies by crystal color: red defeats enemies outright, purple immobilizes, yellow binds with ropes, and blue traps in bubbles. Initially, she maintains this form for only five minutes due to energy limitations, but sustains it indefinitely after obtaining the Golden Crown of Wisdom. A Japan-exclusive power-up depicts her gaining a fiery red aura through self-belief, enhancing her strength.

Her developmental arc begins with isolation and criticism of others, driven by urgency to reclaim Splendorius. After intervening to save the team from Regina’s assault, she confiscates Maya’s Glitter Charm to instill resilience, returning it only when Maya demonstrates courage. During a festival crisis, she allies with Maya to defeat distains, signaling growing trust. This evolution peaks as she transitions from viewing teammates as liabilities to embracing them as essential partners, reconciling her regal duties with personal connections. Trivia notes her unique dual statuses: youngest chronologically but oldest physically when transformed, and shortest normally but tallest as Glitter Ace. Her surname "Miller" was revealed via a doorbell at her residence.
