Born in Hokkaido, Special Week is a bright and cheery, hardworking Umamusume. After losing her birth mother, Special Week was raised by her mother's friend. Now, she hopes to make both her moms proud by fulfilling her promise of becoming Japan's top racer.

An Umamusume seen as a prodigy who's always ahead of the pack, both figuratively and literally. She gets so absorbed with running that she comes off as aloof, but most know that she is dedicated. She is roommates with Special Week and many find themselves drawn to her authentic personality.

A bright, bubbly Umamusume with a natural knack for racing. She's long looked up to the student council president, Symboli Rudolf, and this admiration serves as her ultimate motivation in becoming the number one racer. Fans loves Teio's boundless confidence, and have lovingly dubbed her upbeat march the "Teio Step."

Dedicated to being the coolest, this Umamusume tries her best to act like a delinquent. She takes after her motorcycle-loving father, emulating his hobbies and attitudes down to the letter. Her grandstanding nature sees her charge daringly into any challenge, never afraid of what she might face. She has a bit of a cat-and-dog relationship with her roommate, Daiwa Scarlet.

Unyielding, strong-willed, and cheeky, she wants to be number one at everything she does. She usually plays the role of the perfect, mild-mannered honor student, but the truth is that she hates losing more than anything else. If it'll help her be number one, she'll go through any training. She sees her rather showy roommate Vodka as both her motivation and her rival.

An unpredictable firebrand born with an extra helping of free spirit. She's prone to some dramatic swings in mood and motivation. She seems to get along with anyone and everyone, but it is unclear just how she views her bonds with others. Truly, one could call her Tracen's greatest mischief-maker.

Born into a family of racing legends, Mejiro McQueen is a long-distance runner who is the envy of her peers. She has class and decorum befitting her prestige, and is determined to take first at the Tenno Sho like many Mejiro racers before her.

Ever bright and cheerful, she loves festivals more than anyone else. Her innate altruism makes her unable to ignore a person in need, and she's always ready to lend an ear. Her bottomless kindness has earned her the admiration of those around her, but when she gets too excited, her words take on a certain festival flair.
