Released globally in mid-2025, Uma Musume: Pretty Derby features female characters who personify real-life racehorses. With its cute visual style and spirited storylines, the game also serves as an educational gateway to the world of horse racing — a world many young people may not yet be familiar with.
 

Mejiro McQueen represents elegance and endurance. In real life, she was a long-distance race specialist with extraordinary stamina and hailed from the prestigious Mejiro racing family in Japan.

At the peak of his career, T.M. Opera O reigned supreme. He held an unbeaten record in Japan and once swept all major titles, including the coveted Triple Crown. It’s no wonder he’s considered one of the most dominant racehorses of his time.

In the game, he’s portrayed as flamboyant and narcissistic, constantly declaring himself "the greatest, the most beautiful, and the most brilliant." His confidence isn’t unfounded — the real-life horse truly had the talent to back it all up. Dramatic yet legendary.
 

Rice Shower won fans' hearts most unexpectedly. Known as the “spoiler,” he often disrupted the victories of race favorites in major competitions — and that’s exactly why he’s remembered. He proved you don’t have to be the champion to be loved.

In Uma Musume, Rice Shower is depicted as quiet and self-doubting, a girl who simply wants to run freely. But the world often misunderstands her. She’s a symbol for those who may not be perfect, yet still give their all in life’s race.
 

Narita Brian is a true legend. A Triple Crown winner from the 1990s, he was renowned for delivering outstanding performances under intense pressure. He wasn’t just fast — he was mentally tough.

In the game, Narita Brian is the classic “lone wolf” — quiet, cold, and intensely focused. He rarely speaks, but when she hits the track, no one can ignore her. She embodies quiet strength and fierce ambition.
 

Unlike the others, Haru Urara is famous not for winning — but for never winning. This horse raced dozens of times and never claimed victory. Yet that’s precisely what made her legendary: she became a symbol of hope for the Japanese people during tough times.

In Uma Musume, Haru Urara is cheerful, energetic, and never gives up, even when the results aren’t pretty. She teaches that the courage to keep trying matters far more than winning. Her character is proof that not all heroes need to win to be inspiring.
