First person: I (rough, energetic) Captivated by Fuji Kiseki's running, she aims to be the "strongest." She has an energetic personality and can't sit still when she sees a strong rival run. She also has an innocent, almost childish side. She calls her admired senior, Fuji Kiseki, "Fuji-san."

First person: I (polite, intellectual) 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 regardless of what others think, but her running is overwhelmingly powerful. She is immersed in the goal of "pursuing the further possibilities dormant within Uma Musume," viewing races as laboratories and other Uma Musume as test subjects. She sometimes skips class to conduct research. She frequently drinks black tea.

First person: I (quiet, polite) An Uma Musume with beautiful jet-black hair and a dark, mysterious atmosphere. She is always with an "friend" that others cannot see and tends to keep to herself. Behind her quiet demeanor lies a burning desire to "catch up to her friend." Her favorite drink is coffee.

First person: I (soft, polite) A kind-hearted Uma Musume who is soft-spoken and considerate of those around her. She spends her school life often being swept along by her unique classmates. She never gives up on winning a race. She hides a strong core behind her gentle eyes and trains hard to shine on the big stage.

First person: I (theatrical, confident) The battle-hardened absolute champion of the Twinkle Series. She is called the "Supreme King" due to her overwhelming strength. Her behavior is always theatrical, and she is a confident individual who believes the world revolves around her. The other Uma Musume she competes against in races are, to her, important co-stars who help her, the lead, shine. Her ability to win from any situation makes her truly worthy of the title "Supreme King."

First person: I (soft, boyish) An Uma Musume who is responsible, caring, and beloved by everyone. She was undefeated in four races since her debut and was expected to win the Triple Crown, but an injury prevented her from competing. She has high expectations for Jungle Pocket's talent and motivation, and she kindly encourages and supports her as a developing Uma Musume.

First person: I (polite, formal) A refreshing honor student full of sportsmanship. She is a hard worker who continues to face high walls head-on to meet the expectations of those around her. She puts in constant effort aiming for the top of the Twinkle Series.

First person: I (timid, humble) A clumsy Uma Musume who has absolutely no self-confidence. Things often go wrong and she tends to be negative, but she is also a hard worker who never gives up. She admires T.M. Opera O, who is her complete opposite and always full of confidence, and has finally fought her way up to stand alongside the powerhouses of the Twinkle Series.
