As with all prior playable Trainees, Believe is based on the real racehorse of the same name. The mare was born in 1998 from the American horses Sunday Silence and Great Christine. Her racing career spanned from 2000 to 2003, during which she recorded ten wins, including two G1 victories in Japan at the 2002 Sprinters Stakes and the 2003 Takamatsunomiya Kinen.

The Japanese reveal of Believe followed a server outage that affected not only Umamusume but also Cygames’ other titles like Granblue Fantasy and The Idolmaster Cinderella Girls: Starlight Stage. The outage lasted for around 4.5 hours, and Cygames has also compensated by sending 150 jewels to all players who started before the outage.

Meanwhile, the global English version of Umamusume: Pretty Derby is still catching up with the addition of Hishi Amazon, who first appeared in the Japanese release in June 2021. In early September 2025, Cygames also added Seiun Sky to the global release’s roster.

Umamusume: Pretty Derby is available worldwide on iOS, Android, and PC.
