From a young age, equine heroines Kitasan Black and Satono Diamond have looked up to their peer Toukai Teiou, dreaming of following in her footsteps. In pursuit, they join Tracen Academy, a school devoted to honing horse girls and readying them for championship contests. Shortly thereafter, Kitasan Black secures a spot on Team Spica, the same squad as Teiou. Fueled by ambition, she stays unbeaten until her first Grade 1 (G1) event—the league"s most elite race—eludes her, yet she vows to unlock her full potential as a horse girl in the upcoming season.
At the same time, Satono Diamond hails from a lineage of horse girls who, despite remarkable speed, have never clinched a G1 title. She must finally lift this streak and grant the Satono family the honor they deserve, with unwavering resolve to victory.
