In Tokyo, elite horse girls and rising prodigies dominate the national racing scene. Rookie trainer Jou Kitahara arrives with big dreams but modest hopes, never expecting to find hidden talent in the quiet town of Kasamatsu—until he encounters an ash-gray-haired girl with a wild, unrefined running style.
Oguri Cap spent her childhood hindered by weak knees, enduring pain just to stand. Through sheer determination, she overcame her limitations and discovered freedom in the very activity that once seemed unattainable: running. While other horse girls in Kasamatsu strive for victory and recognition, Oguri runs without purpose, motivated solely by the joy of movement.
Fujimasa March, a rising regional star, commands respect through her discipline, skill, and fierce determination. For her, running is a point of pride. However, when a school-organized race pits her against Oguri's raw, untamed stride, March's self-assurance begins to erode. In turn, something within Oguri changes after competing with March. For the first time, a flicker of ambition awakens in her—a longing to win that will carry her beyond her small hometown toward the grand stages that await.
