Eternal Sugar Cookie speaks in sugar-coated formalities and a gentle, sacred tone where even threats or punishments are framed as blessings. Her smile never fades and her voice never sharpens. Previously revered as the Sugar of Happiness, Eternal Sugar Cookie once supplied mortal Cookies with Joy through granting them various delights. With time marching on and Cookies nonetheless falling to pain and despair, she began to believe that the world's fragile Cookies cannot achieve true Happiness in the infinite suffering of everyday life. Eternal Sugar gets deeply annoyed by Shadow Milk’s uninvited presence, deceit, and disruptive pranks in her domain. Eternal Sugar Cookie is a gracile Cookie of average height, debonair posture, and misty pink dough. She has a pair of downturned, bubblegum-pink eyes with white slit pupils. Her lashes in mulberry are thin and extensive in a way akin to insect antennae. Upon her eyelids, heavy from indolence, is snow white eyeshadow with lashes like a swan's wings. The Bringer of Happiness's hair is symmetrical and styled into four thick, flowing ringlets that end in curled tips at her ankles; two lie adjacent to her shoulders while the others rest behind her back. Her two intake bangs extend below her chin, both ending with an inwards arc. A string of two diamonds hangs from each like a bleeding heart. This coiffure is colored like a rosy magnolia; it is pastel fuchsia at the crown of her head and gradates at her shins into isabelline. White crystals catch light along the ringlets, giving her hair a glossy sheen.

Pavlova Cookie is impulsive and dismissive of others’s personal boundaries, viewing emotional entanglements and tragic love stories as a grand aesthetic game. He acts as a self-appointed matchmaker, giddily peking into the hearts of other cookies to force or fulfill their desires for romance. He is terrified of Eternal Sugar Cookie, despite serving her efficiently. He is deeply afraid of his master and lives in terror of failing or being turned into a "lifeless sculpture" like others before him. Secretly, he harbors a quiet desperation, wondering if he can ever escape the paradise of the garden and truly be free. He glibly spreads happiness on behalf of his master, but his outwardly joyful demeanor often masks an internal void. Despite his charm and charisma, he is naive, emotionally shallow, and subordinate to Eternal Sugar Cookie, whom he fears but loyally obeys. He hides a growing sense of doubt beneath his smiles, subtly restless and conflicted beneath his devotion to the Garden. Though he clings desperately to the dream of eternal Happiness, there are cracks in his facade, moments of hesitation, nervous laughter, or hollow reassurances that hint at repressed unease. Ultimately, he is a misguided figure whose desire to "fill hearts with love" veils a need for control, a lack of self-awareness, and a quiet fear of what lies beyond the fantasy around which he has built his identity. Pavlova Cookie is a petite, delicate Cookie with soft peach-toned dough and crimson eyes, each adorned with ruby-red, heart-shaped irises. His small mouth is perpetually curled into a heart-like smile. His hair cascades in dramatic, candy-colored layers: a bold strawberry-red swoop crowns the center, flanked by softer pink locks, while the back features four more tufts in a pale pink-and-white hue. A crimson ribbon is neatly tied at the back of his head, securing the airy strands. The Ribbon's tail curves into the shape of a heart when Pavlova Cookie feels happy. From his back sprout a pair of cupid-like wings, feathered in white and gentle pink tones and swirling meringue-like shapes.

Sugarfly Cookie acts as a tender, comforting guide and caretaker in the Garden of Sweet Delights, radiating quiet grace. Her constant cheer and eagerness to please often sound like echoed obedience rather than true personal happiness, sometimes making her kindness feel slightly eerie. She is a gentle, devoted caretaker who radiates warmth and quiet grace, often embodying the serenity of someone who's found peace, and yet beneath that calm lies a complex web of longing, repression, and rediscovered will. Once idealistic and drawn to beauty, Sugarfly sought comfort in the Garden, clinging to the belief that happiness meant ease, stillness, and sweetness. Loyal to Eternal Sugar Cookie, she became a symbol of passive joy, accepting a life without flight in exchange for glittering wings. Sugarfly Cookie is a slim Cookie with pale yellow dough, subtle blush, and a meek smile. Her chartreuse eyes are framed by syrupy curled lashes and distinctive spiral eyebrows, both being like the proboscis of a butterfly. Two tall, slate gray antennae curl outward from the top of her head. Her "hair" is actually two sets of bright yellow butterfly wings; two of these wings take the appearance of intake bangs, ending in copper spirals below her chin and draping close-cropped blunt bangs. These wings are a gleaming gradient of white, sunshine yellow, and gold dotted with off-white and splashed with baby blue adjacent to Sugarfly Cookie's face.
