Tamamo Cross

Height: 140 cm (one of the shortest Umamusume, which is why she is often called a little one / pint-sized).

​Weight: Hard to determine, but it is heavier than a human's because Umamusume have a denser muscle structure than humans.

​Bust: 71 cm

​Waist: 52 cm

​Hips: 73 cm

​Shoe size: Left — 19.5 cm, right — 20.0 cm

​Eyes: Rich, bright sky blue (deep blue). Her gaze is lively, piercing, and intensely determined. Her eyebrows are often slightly arched in a tent shape, giving her face an expressive, fighting, and slightly sassy expression.

​Smile trait: When she smirks or gets angry, a small fang often peeks out funnily from the corner of her lips, emphasizing her "hooligan" and sassy disposition.

​Head accessories: She wears a red fabric headband on her forehead (which is almost hidden behind her bangs), and a blue hair hoop where her hair meets. Her animal ears are fitted with special red ear covers, and a signature red-and-blue decorative sphere adorns her right ear.

​Ears and tail: Her horse ears and tail completely match the silvery color of her hair. Her tail has a tendency to "sparkle" (though not literally spark) and get covered in goosebumps / static electricity when Tamamo gets angry or overwhelmed with emotion.

​Close Relations

​Her main rival and good friend is Oguri Cap (white hair, ears, and tail, and blue eyes), who possesses a startling, bottomless appetite.

​Outfits

​Tamamo has several outfits, each highlighting her style:

​1. Signature Racewear ("White Lightning")

This is her main and most recognizable outfit for races:

​Jacket: A bright blue, long-sleeved cropped jacket, open in the front. A stylized lightning bolt print is featured on the back and clothing details.

​Top: A light blue, form-fitting short-sleeved crop top with a lightning bolt design on the chest, completely exposing her midriff and navel.

​Pants: White tapered cropped trousers (capris) with red stripes down the sides and a belt with a metal buckle.

​Footwear & Accessories: White fingerless gloves, bright red socks/leggings, and chunky blue-and-white sneakers with red heels and lightning bolt patterns.

​2. Tracen Academy Uniform

​Summer/Winter Variant: On her miniature figure (140 cm), the standard uniform fits very compactly. She wears a lilac sailor-collar blouse with puffy short sleeves, complemented by a purple bow tie.

​Skirt: A white short pleated skirt with a petticoat.

​Footwear: White knee-high stockings (creating a zettai ryouiki effect) and standard brown Umamusume shoes with strap horseshoes.

​3. Casual Style & Stage Outfits (e.g., Starting Future)

​Outside of training or in stage looks, she often prefers comfortable streetwear: cropped light jackets, a red inner vest, shorts combined with a light decorative wrap skirt, purple or blue stockings with garter straps, and a stylish purple choker around her neck.

​Personality & Temperament: Spirited, sassy, incredibly energetic, and sharp-tongued. She flares up instantly, but cools down just as fast (she doesn't hold grudges). ​Height Complex: She can't stand being underestimated because of her short stature (140 cm) or being called a "little one" — in response, she instantly strikes a fighting stance and goes off on a full tirade. ​Speech Peculiarity: Speaks entirely with the flavor of the Kansai dialect (Osaka accent) — uses expressive slang, blunt turns of phrase, and colloquial expressions ("What do you want?", "Have you lost your mind?"). ​Family & Care: Beneath her outer roughness lies a deep care for her loved ones. She is the eldest sister in a large family, so she is used to looking out for others, even if she does it her own way with a bit of grumbling. ​Financial Pragmatist & Frugality: Knows the value of every single yen. She loves discounts, deals, and sales (her ears instantly perk up at the word "sale"). She is an absolute master at making delicious, budget-friendly meals (takoyaki cooked on a gas stove, bean sprout dishes, and kamaboko). ​Hatred of Laziness: Can't stand kotatsu heaters, believing they corrupt willpower and turn an athlete into a slacker. She gives 100% on the running track. ​Favorite Food: Takoyaki, bean sprouts, okonomiyaki, or dishes featuring kamaboko.

Tracen Academy: The premier and most prestigious sports academy in Japan, designed specifically for training Umamusume. Beyond standard academic subjects, students undergo grueling daily athletic training, study race strategy, and prepare to compete in the professional Twinkle Series league. ​Ritto Dormitory: One of the two primary dormitories at Tracen Academy (named after a real-world elite horse training facility in Japan). It is well-known for its lively, high-energy, and fiercely competitive athletic atmosphere. This is where Tamamo Cross resides alongside many other passionate racers.
