Maya Aida, identified as Mana Aida in the original Japanese version, commands the Glitter Force Doki Doki team. Her civilian life centers on Ōgai Middle School, where she excels as a student council president and middle schooler, celebrated by peers and adults alike for her sharp problem-solving skills and unwavering trustworthiness. Her family runs the Pigtail restaurant.

Maya possesses distinct magenta eyes and short, flared dark pink hair, partially gathered into a small ponytail secured with an off-white bow. Her typical casual outfit features a white and lilac striped long-sleeve shirt beneath a pale pink top adorned with a heart design, paired with a ruffled light pink mini-skirt, lilac stockings, and pink-and-white sneakers. A summer variation swaps in a black top under a light pink t-shirt, black leggings, and a layered pink skirt, retaining the sneakers. She consistently wears her Glitter Charm accessory on her bow.

Transforming into Glitter Heart brings dramatic changes: Maya's hair extends into bright blonde, styled into four large curls with a looped ponytail held by a pink-and-white hairpiece featuring heart-shaped accents. Her costume is a pink dress with winged sleeves, white detailing, and magenta-and-white straps across the chest, shoulders, and waist. A magenta ribbon with heart-shaped tails accents the skirt, which incorporates a scalloped pale blue layer and a frilly white petticoat. She also wears magenta shorts, pink-and-white boots with gem heart accents, a pink pointed choker, and magenta heart earrings. Her transformation sequence activates by placing her Glitter Charm onto her partner Kippie’s medallion, declaring "Glitter Force Makeover," and tracing "L-O-V-E" on her Glitter Pad.

Achieving Parthenon Mode, an advanced state unlocked through combined team powers, further alters her appearance: her hair lengthens and large white wings manifest. Her attire shifts to a pale pink hue with white accents, including a ruffled cape displaying a winged heart motif and a gold neckline. This form grants significant power amplification.

Maya radiates a cheerful, courageous, and empathetic personality. She demonstrates excellence in academics and sports, frequently steps in to resolve conflicts, and actively assists others to ease their burdens, though she occasionally acts impulsively. Notably, she is tone-deaf. Her inherent kindness and leadership inspire deep trust, yet she often internalizes stress to avoid troubling others. She maintains enduring childhood friendships with Rachel (her student council secretary) and Clara, and holds profound admiration for the idol Mackenzie Mack, who later joins her team.

Her primary bond is with Kippie, a rabbit-like pixie serving as her transformation partner and the provider of the Glitter Pad. Maya actively protects Regina from her father's manipulation; their friendship suffers a temporary fracture due to brainwashing but is restored when Regina defends Maya. Other key connections include Natalie, who offers crucial encouragement during critical moments, and Nicholas, an elementary school friend whose secret affection remains unnoticed by Maya.

Maya's journey initiates during a Clover Tower school orientation where she aids a lost child and encounters Mackenzie. Witnessing a Distain attack, she is chosen by Kippie, transforming into Glitter Heart for the first time to save Glitter Spade (Mackenzie). As Glitter Heart, she commands attacks including "Let Your Heart Light Shine" (a purification technique using the Glitter Pad and Charm), "Heart Shot" (utilizing the Glitter Heart Arrow), and "Love Bubble" (deployed with the Glitter Crystal Pad). She also contributes to group maneuvers like "Togetherness Power Arrow" and "Five of a Kind Glitter Bow."

Her development includes mastering an unnamed power-up by adhering to Glitter Force principles, enhancing her strength and enabling advanced applications of the Glitter Heart Arrow. Parthenon Mode represents her peak power, attained through team synergy and legendary artifacts: the Miracle Dragon Glaive and Golden Crown of Wisdom. Throughout her battles, Maya consistently prioritizes others' well-being, leveraging her role to shield both her world and the magical kingdom of Trump from Distains.

Etymologically, her Japanese name "Mana Aida" (相田 マナ) combines "ai" (signifying togetherness or love) and "da" (field), meaning "the love between people." The localized name "Maya" derives from Hindu philosophy, meaning "illusion" or "magic," while "Aida" is Italian for "helpful." Her Glitter Heart persona embodies the theme of love, encapsulated in her catchphrase: "Feel the Doki Doki!"
