Uma Musume: Pretty Derby - BNW no Chikai (OAV)

Narita Taishin's racing costume is primarily colored pink after the racing silk worn by the jockeys that raced with the real racehorse (1990-2020).

Biwa Hayahide's hair is colored white after the real racehorse (1990-2020). Her racing costume is pink and black with a zig-zag pattern after the racing silk worn by the jockeys that raced with the the real Biwa Hayahide. Her long, fluffy hair is a reference to the racehorse having a big head. The racehorse won the Japanese Horse of the Year award in 1993.

Winning Ticket's racing costume uses the colors red and blue after the racing silk worn by the jockeys that raced with the the real horse (1990-2023)

The term "BNW" was coined by horse racing enthusiasts to describe the three racehorses that dominated the Classic Japanese Triple Crown during the 1993 season, when Biwa Hayahide won the Kikuka Sho, Narita Taishin won the Satsuki Sho, and Winning Ticket won the Tokyo Yushun (Japanese Derby).

Gold Ship's racing costume is colored red after the racing silk worn by the jockeys who raced with the real racehorse (foaled March 6, 2009). The six gold buttons symbolize the racehorse's G1 wins. Her boots have red ribbons, which are used in horse racing to warn people that the racehorse is aggressive and has a tendency to kick.

In real life, Daiwa Scarlet (foaled May 13, 2004) is the daughter of Agnes Tachyon (1998-2009).

At 180 cm, Hishi Akebono is the tallest uma musume at Tracen Academy. This is a nod to the real racehorse (1992-2008) being the heaviest (560 kg) to win the Sprinters Stakes in 1995. The racehorse was named after the sumo wrestler Akebono Taro (1969-2024). The uma musume's racing costume uses the white and blue colors of the racing silk used by the Hishi horses owned by Masaichiro Abe.

Air Shakur's racing costume uses the yellow and blue colors of the racing silk worn by the jockeys that raced with the real racehorse (1997-2003). As depicted in the OAV, she has tattoos and wears spiked bracelets as an homage to rapper Tupac Shakur, who was the racehorse's namesake. Prior to the release of the video game, she underwent a redesign, with a black jacket and leather shorts replacing her original costume, and her tattoos erased.

Prior to the release of the anime series, Ayaka Imamura was originally announced as the voice of Mayano Top Gun, but she retired in 2018 due to health issues. Mayano Top Gun has since been voiced by Mio Hoshitani.

If an uma musume has an accessory on her right ear, this means the original racehorse was a stallion (male). It it's on the left ear, the racehorse was a mare (female). The only exception to this rule is Fine Motion, as she has accessories on both ears. This is because the real racehorse (foaled January 27, 1999), while being a mare, was discovered to have chromosomal abnormalities after several failed matings with King Kamehameha (2001-2019). This revelation has led to numerous rumors and jokes that Fine Motion was a hermaphrodite horse. In addition, Fine Motion was originally introduced in the game as an Irish princess. However, as Ireland is a republic and not a kingdom, Cygames rewrote her origin in 2025, making her a descendant of ancient royalty that moved to Ireland, and her father was now a government official instead of a king.

When Gold Ship introduces Team N in episode 15, each member does a Kamen Rider pose: Agnes Tachyon (Kamen Rider W), Gold Ship (Kamen Rider 1), Air Shakur (Kamen Rider Build), T.M. Opera O (Kamen Rider Den-O), Mihono Bourbon (Kamen Rider Kabuto), and Seiun Sky (Kamen Rider Black).

In episode 16, Gold Ship imitates Michael Jackson's 1993 Dangerous World Tour appearance on her entrance to the track.

Gold Ship's incident with Air Shakur at the Osaka Hai in episode 16 is based on the 2015 Takarazuka Kinen, when the real Gold Ship reared right when the gates opened, and he finished second-last. This became known as the "12 Billion Yen Incident" as a combined ¥12 billion was lost from betting on Gold Ship. Commentator Junko Hosoe even re-enacted her screams from the original broadcast.
