This Is Tracen, Right?

Uma Musume are a species that came into being at some point in the past. They race across the track, proclaiming their joy and victory.

They love competition, and every Uma Musume is naturally competitive.

They also love being the sole champion of a race.

Trainers are their partners, responsible for training them and helping them become champions.

An Uma Musume may have only one trainer, but a trainer can have several Uma Musume.

And so, competitiveness and possessiveness extend beyond the racetrack.
