Daiwa Scarlet embodies fierce competitiveness and pride, driven by an unrelenting perfectionism and deep-seated refusal to accept defeat. Outwardly, she projects the image of a poised, courteous honor student, yet beneath this polished facade lies a tenacious, unyielding spirit. Her relationship with roommate Vodka crackles with rivalry, marked by constant clashes and mutual one-upmanship, mirroring their real-life counterparts’ historic duel across five major races, each claiming two victories. A disciplined strategist, she methodically charts goals in bold red ink and self-reflections in crisp blue within a dedicated notebook, showcasing her relentless pursuit of growth. Her striking appearance features long auburn twintails secured by blue ribbons, a tiara crowned with a vivid blue gem, and a race outfit embellished with symbols of her triumphs—four pearls gleaming on her headpiece as emblems of her Grade 1 conquests. Drawn to Agnes Tachyon’s intellectual brilliance, she eagerly volunteers as a test subject for Tachyon’s experiments, echoing their real-life sire-daughter bond. Connections with Aston Machan and Eishin Flash further shape her narrative, the latter partnership culminating in the birth of Umbrella Date, a nod to their lineage. In media, she thrives in collaborative challenges, co-organizing a city-wide relay race in the *BNW no Chikai* specials alongside Team Spica, where her problem-solving and teamwork shine. A quirk of her perfectionism surfaces in her unerring ability to draw flawlessly straight lines freehand. Her design channels early 2000s tsundere archetypes, blending elegance with hidden intensity—subtly betrayed by expressive ears that flicker with unfiltered emotion and a tail demanding daily grooming battles. Contrasting Vodka’s exuberance, she balances delicate grace with ironclad resolve. Background nods to her legacy include her historic Arima Kinen victory as the first mare in 37 years, immortalized in-game, and her breeding history: ten fillies preceding a lone colt, with a granddaughter’s lineage intertwining with Vodka’s descendants, quietly anchoring her enduring influence.
