Daiwa Scarlet — Umamusume: Pretty Derby

In the first chapter of Scarlet's personal story, Vodka catches her near the finish of an academy tryout and wins. Scarlet is shaken by second place, then pushes herself through punishing extra practice rather than accepting that a strong performance can still end in defeat. Her reaction exposes how tightly she has tied her sense of worth to being number one.

Other trainers attempt to recruit her but suggest that she imitate Vodka's race strategy. Scarlet resents being treated as a lesser version of her rival, and her frustration begins to cost her interest from would-be coaches. Air Groove then confronts her about breaking curfew to train and warns that overwork could cause injury. When Scarlet starts to despair over having been a standout in her hometown but losing at Tracen, Air Groove insists that falling short need not be the end of her ambitions.

The story's prospective trainer continues trying to recruit Scarlet even after she openly admits to being stubborn, selfish and difficult. Rather than asking her to become more agreeable, the trainer proposes that they pursue first place together and discuss training disagreements honestly. That acceptance finally breaks through her defensive pride, and she agrees to work with the trainer.

To restore her confidence, they arrange a rematch with Vodka. Scarlet commits to an aggressive lead and an earlier final surge after concentrated stamina work. This time she holds on to win. Vodka promptly demands another match, and Scarlet welcomes the challenge: victory renews their rivalry rather than ending it.

Later, Scarlet repeatedly takes on requests from teachers and classmates while also maintaining her training schedule. She wants to be the person everyone can rely on and struggles to accept the trainer's offer of help. The apparent contradiction becomes clear: although she can be genuinely considerate, she fears that letting someone share her work means failing her own ideal of competence.

While searching for a present for her mother, Scarlet explains how deeply she admires her mother's racing career and work. She remembers a congratulatory voicemail after an early victory and says the brief messages she still receives after wins mean a great deal. When commercial gifts seem inadequate, the trainer suggests dedicating a race victory to her mother. Scarlet embraces the idea, wins, and receives a congratulatory call that visibly delights her.

At summer camp, hard running on the beach leaves Scarlet unsteady, but she initially refuses to stop. When she nearly collapses from fatigue, the trainer persuades her that rest is part of effective training. Later she admits, indirectly and with her usual embarrassment, that she can trust the trainer to handle the preparation and to care about her well-being. The character story closes with Scarlet still determined to become number one, but now acknowledging that she cannot reach that goal entirely alone.

Scarlet's original playable career sets race objectives that include the Tulip Sho, Oka Sho, Japanese Oaks (which has a possible alternative objective), Shuka Sho, Queen Elizabeth II Cup, Osaka Hai, Tenno Sho (Autumn), and Arima Kinen. Placement requirements vary: the final two listed goals specifically call for victories. These are gameplay objectives, not proof of one unavoidable, fully canonical sequence of results. Her seven-chapter personal story closes on an evolving partnership with her trainer; it does not establish a fixed retirement or final lifetime outcome.
