Umamusume: Cinderella Gray

Tokyo draws the nation’s top horse girls and the next wave of elite runners, but rookie trainer Jou Kitahara isn’t expecting to find anyone special in the quiet town of Kasamatsu. That changes when he notices an ash-gray-haired girl whose untamed, unconventional stride stands out from the pack.

Oguri Cap grew up hampered by weak knees and constant pain, fighting just to stay on her feet. Through sheer persistence, she pushes past her limits and discovers freedom in running—something that once felt out of reach. Unlike her classmates who chase recognition and results, Oguri runs simply for the feeling of movement, until a school race pits her against Fujimasa March, a disciplined regional standout who treats every sprint as a matter of pride. Their encounter unsettles March’s certainty and stirs something new in Oguri: a first, clear hunger to win, pointing her toward challenges far beyond Kasamatsu.
