First person: I (rough, casual) Height: 158cm Weight: Who knows Measurements: B77 • W56 • H80 Grade: Senior High Captivated by Fuji Kiseki's running, she aims to be the "strongest." An energetic personality who can't sit still when she sees a strong runner. She has an innocent, almost childish side. She calls her idolized senior, Fuji Kiseki, "Fuji-san." Overall, she is a passionate soul with intense emotional highs and lows. A tomboy with a rough and blunt personality; she usually speaks very loudly and often shouts when she wins or is happy.

First person: I (polite/intellectual) Height: 159cm Weight: Refused measurement Measurements: B83 • W55 • H81 Grade: Senior High A mad scientist with a genius intellect who will use any means to achieve her goals. She is treated as an eccentric because she prioritizes research over social norms, but her running is overwhelmingly dominant. She is absorbed in the goal of "pursuing the further possibilities sleeping within Uma Musume," viewing races as laboratories and other Uma Musume as test subjects. She sometimes skips class to conduct research. She drinks tea frequently. Her life skills are so low that her daily life would fall apart without someone to support her. Her "results are always the real deal," and despite her quirks, her talent as a scientist is undoubtedly top-tier. While a mad scientist, she hates doping (claiming "nothing is more boring than doping"). Though a dangerous person avoided by those around her, she rarely does anything to actually cause physical harm to others.

First person: I (polite) Height: 155cm Weight: No change Measurements: B73 • W54 • H78 Grade: Senior High A dark and mysterious Uma Musume with beautiful jet-black hair. She has a spiritual medium constitution. She is always with a "friend" that others cannot see, and tends to withdraw into her own world. Behind her quiet demeanor lies a burning desire to "catch up to her friend." Her favorite drink is coffee. She generally speaks in polite honorifics and addresses others with "-san." Agnes Tachyon describes her as "an eccentric just like me." "The Friend" A being that Manhattan Cafe has seen since childhood, neither ghost nor monster. According to Cafe, the friend looks very similar to her. The friend possesses incredible speed, particularly in cornering and flexibility, to a degree that even the highly talented Cafe finds astonishing.

First person: I (polite/feminine) Height: 163cm Weight: Not confident Measurements: B90 • W60 • H88 Grade: Senior High A good-natured Uma Musume who can't help but go along with whatever others ask of her. She lacks self-confidence but works hard with the simple hope of being able to run forever. Because she is easily swayed, she is often dragged around by her more eccentric peers. She never gives up on winning a race. She hides a strong core behind her gentle eyes and trains hard aiming to shine on the big stage. An altruist at heart, she often responds cheerfully even to unreasonable requests, accepting even the dangerous Tachyon's favors without a second thought.

First person: I (soft/theatrical) Height: 156cm Weight: Always perfect (self-proclaimed) Measurements: B76 • W55 • H80 Grade: Junior High A grandiloquent narcissist and a somewhat comical "Opera King." Her behavior is always over-the-top, speaking of her self-love sometimes loudly, sometimes soulfully. A tomboyish girl who always wants to be the protagonist. While other Uma Musume are exasperated by her narcissism, they watch over her with kind eyes. She aims to become the "Supreme Ruler." A confident person who believes without a doubt that the world revolves around her. The other Uma Musume she competes with in races are, to her, important co-stars for her own brilliance as the lead. Since she has little interest in things lacking emotion or narrative, her academic grades at Tracen Academy are poor enough that she regularly ends up in remedial classes. Unless something extreme happens, she rarely insults or looks down on others.

First person: I (soft/androgynous) Height: 168cm Weight: No change Measurements: B84 • W58 • H82 Grade: Senior High A responsible and caring Uma Musume who is admired by everyone.

She has high expectations for Jungle Pocket's talent and drive, kindly encouraging and supporting her as an inexperienced Uma Musume. A highly observant person who watches people closely. She applies this observational power to her racing as well. Due to her approachable personality and her role as a dormitory head who cares for others, she is popular both inside and outside Tracen Academy.

She generally speaks in a polite register even to classmates and juniors. A hard worker who continues to face challenges head-on to meet the expectations of those around her, no matter how high the wall. She trains relentlessly aiming for the top of the Twinkle Series. When overcome with emotion, her vocabulary tends to drop sharply.

First person: I (polite) Height: 164cm Weight: Slight increase in some areas Measurements: B99 • W61 • H89 Grade: Junior High A typical klutz who fails at everything she tries, yet still wishes and aims to "change herself" and "not give up." While she tends to be negative because things often go wrong, she is also a hard worker who tries again without getting discouraged. She admires T.M. Opera O, who is her polar opposite and always full of confidence. She is a poor cook; apparently, an Uma Musume who tasted her Valentine's chocolate collapsed. Surprisingly, she loves extremely spicy food. She seems to have a constitution that naturally attracts animals.
