Uma Musume: Pretty Derby - BNW no Chikai

Biwa Hayahide, Narita Taishin, and Winning Ticket once stood out not only for their fierce racing but for the friendship that made the trio BNW special. Lately, however, the three have drifted apart, and even those around them can see that something between them has changed.

When Tracen Academy plans a relay race for its fan festival with each BNW member leading a different team, Team Spica is tasked with persuading all three to participate. Winning them over is difficult enough; repairing the bond beneath their rivalry is harder. The coming relay may be the chance they need to remember why racing against one another once brought them closer.
