Uma Musume: Pretty Derby Season 3

Kitasan Black and Satono Diamond grow up admiring Tokai Teio and dreaming of reaching the greatest races themselves. Kitasan joins Team Spica and begins with enormous confidence, but her first serious defeat forces her to consider what kind of runner she wants to become instead of simply following her idol's path.

Satono Diamond carries a different burden: no horse girl from her family has managed to win a G1 race, and she wants to break that long-standing curse. The two friends support each other while inevitably becoming rivals as their careers advance. Through injuries, pressure, and painful losses, the simple dreams of childhood become harder choices about changing, enduring, and running toward goals that belong to each of them.
