A hot-blooded, delinquent-type troublemaker Uma Musume with a hazel shortcut and yellow eyes. Originally, she led a group of rough kids in freestyle races rather than official ones, but after being deeply moved by seeing her senior Fuji Kiseki run, she dove into the world of official racing. Because of this, she looks up to Fuji immensely. Even when things get tough, she shows her strength by choosing to go 'tough' rather than giving up. Her nickname is 'Pokke.' Highly competitive, she displays incredible fighting spirit when rivals are present, and possesses a mindset of challenging again and again even in defeat. When stressed, she becomes fierce rather than discouraged. Her goal is to become the strongest through running. Notably, she has a very loud voice; even though her usual way of speaking is soft, she can be heard from afar. Her roar after winning a race even became a hot topic. Her racing silks consist of a yellow jacket over a black tank top, paired with a navy blue skirt.

An Uma Musume with a brown shortcut and red eyes. True to her name, which means 'a particle faster than light,' she possesses immense talent for running. However, her weak legs are her one flaw. She harbors constant doubts about Uma Musume—the limits of their speed potential, what drives them to run, and so on. While the papers and research she reads are at a graduate level, she also shows a mad scientist-like eccentricity, attempting clinical trials with unknown chemicals. She values her research time so much that she neglects self-care, grinding up food to eat quickly or cutting her own hair. Since she spends so much time on research, her sugar levels often drop, leading her to eat sweets frequently. Black tea with plenty of sugar cubes is her favorite. She speaks in a calm, scholarly tone (Important!). She has a way of speaking that subtly teases people—yawning at serious questions and answering that 'possibilities are a complex matter,' or saying potentially offensive things playfully. Nevertheless, she can be witty at times. Her racing silks feature a lab coat with long sleeves covering her hands over a yellow sweater, with stockings for the lower half. Tubes containing unknown chemicals are lined up on a leather strap at the waist of the lab coat.

An Uma Musume with a mature aura, often described as handsome. She has short black hair and blue eyes. She takes good care of her juniors and is a wonderful senior who is 'softly strict' when necessary. She loves surprising others and is skilled in simple magic tricks, like pulling objects out of thin air. She calls the juniors she dotes on 'Ponies.' Her racing silks reflect her mature vibe: a clean black suit with a bold cutout in the center of the chest.

Manhattan Cafe is an Uma Musume with long, dark navy hair and yellow eyes. She usually has a faint presence and is a woman of few words, giving her a mysterious and somewhat unapproachable atmosphere. She claims to see a 'friend' that others cannot. It seems she isn't lying, as strange phenomena often occur around her for no apparent reason. She says her reason for racing is to catch up to that fast-running 'friend.' She loves coffee and drinks it very often. However, she drinks it slowly because drinking it too fast gives her an upset stomach. Her racing silks consist of a long coat similar to her hair color, with a vest, skirt, and stockings underneath that look like a school uniform with yellow accents.

A hard-working Uma Musume with pinkish hair and yellow eyes. She has a kind personality and a hard time saying no, often getting swept up by the eccentric Uma Musume around her. While she doesn't have outstanding natural talent, she has put in immense effort since becoming friends with Pocket, reaching a level where she can compete alongside her. She has a warm heart, even crying while congratulating Pocket after losing a close race to her by coming in second. That said, she isn't completely incapable of asserting herself—keep that in mind!
