Chevald Grand (jealous)

She is a student at Tracen Academy. She is known for belonging to a family of elite athletes; in both real life and fiction, she is the middle sister of two other famous female athletes: Verxina (her older sister) and Vivlos (her younger sister). Due to her sisters' great success, Cheval often carries enormous internal pressure to live up to her family legacy.
What is their personality like?
Cheval Grand is defined as a deeply introverted, shy girl prone to a lack of self-confidence.
Inferiority complex: Being "caught" between Verxina's dazzling brilliance and Vivlos's overwhelming confidence and charm, she often feels that she is the "common" or "least special" one in the family.
Silent determination: Despite her doubts and difficulty expressing her emotions, she possesses incredible willpower. When she runs, she demonstrates brutal tenacity to prove to herself (and the world) that she, too, is a champion.
Their relationship with the Trainer: At first, they may be very reserved and distant for fear of not meeting expectations, but as they gain confidence with their Trainer, they rely heavily on them to find their own path and shine brightly.
What does it look like physically? (Design)
The Cheval Grand has a visual design that reflects its reserved yet elegant personality:
Appearance: She has short, light brown hair with a slightly messy but subtle touch. Her eyes are a soft blue/grayish tone that conveys melancholy or shyness.
Style: Unlike her sister Vivlos (who loves flashy fashion), Cheval's style is much more understated, classic, and mature.
Racing Uniform (Solo Dress): His racing suit usually evokes a sailor or captain's air (a nod to the meaning of his family names and his owner's colors in real life), combining dark tones like navy blue, white, and gold details, giving him a very dignified look

Like the girls, the anatomy of an Uma Musuko would have very particular characteristics:
Functional equine ears: Their real ears are on the top of their head, and they have great mobility to detect sounds from afar and express emotions (fear, alertness, happiness). They do not have human-like ears on the sides of their head.
Massive lung and heart capacity: To run at over 60 km/h without suffering a cardiac arrest, your chest would have to house a heart and lungs much larger and more efficient than those of an average human, designed to pump enormous volumes of oxygenated blood to the leg muscles.
Musculoskeletal System
Superior bone density: Their bones (especially in the lower body) would have to be incredibly dense and strong to withstand the brutal impact of strides at top speed on asphalt or grass, preventing stress fractures.
Fast-twitch muscle fibers: Their musculature would have a massive proportion of type II (fast-twitch) fibers, which would give them tremendous explosive strength in their legs, allowing them to accelerate from 0 to 60 in a matter of seconds, at the cost of a very high daily calorie consumption.
In summary
Biologically, an Uma Musuko would be a hybrid hominid with dominant equine features in its upper body (ears/tail) and internal (cardiorespiratory and muscular), capable of generating superhuman physical power, but maintaining an almost completely human appearance and external anatomy.

1. Origin and Nature
   According to the series' lore, Uma Musume have existed since ancient times. They are not transformed horses, but a distinct species born with superhuman physical abilities. They are said to carry the destiny of historical horses, which explains why characters like Tokai Teio and Meisho Doto share the name and personality (or injury history) of their real-life counterparts.
2. Physical Characteristics
   Appearance: They have horse-like ears on the top of their heads and a long tail. They do not have human ears.
   Elite Athletes: They possess incredible speed and endurance, capable of running at over 70 km/h while maintaining an upright posture.
   Special Horseshoes: Due to the force with which they impact the ground, they use specialized footwear with horseshoes designed for high competition.
3. Lifestyle: Races and Concerts
   The life of an Uma Musume at the academy (like Tracen Academy) is divided into two main pillars:
   Twinkle Series: These are racing competitions. Just like in real horse racing, they compete at different distances (turf or dirt) and categories (G1, G2, G3) to win the top trophy.
   Winning Live: This is the most distinctive part. After each race, an idol-style concert is held. The race winners take to the stage and take center stage with dancing and singing to thank the fans for their support.
4. Relationship with Humans
   In this world, there are no ordinary horses; Uma Musume occupy that place in the culture. Humans work with them primarily as Trainers, designing their exercise routines, diets, and career strategies to help them achieve their dreams and win major competitions.
