Umamusume: Cinderella Gray

Synopsis

In the bustling city of Tokyo, elite horse girls and promising young talents dominate the national racing circuit. Aspiring trainer Jou Kitahara begins his journey with ambitious dreams but modest expectations, never anticipating that his breakthrough would come from an unremarkable town like Kasamatsu—until he discovers a girl with ash-gray hair who possesses a raw yet powerful running form. Oguri Cap endured a difficult childhood plagued by weak knees, struggling just to stand upright. Driven by unwavering determination, she overcame her physical limitations and found freedom in running, an activity once thought impossible for her. Unlike her fellow horse girls in Kasamatsu who pursue victory and recognition, Oguri runs purely for the joy of movement, without any particular goal. Fujimasa March, a rising local star, earns admiration through her disciplined approach, exceptional skills, and relentless drive. Running is her passion and source of pride. Yet, during a school-organized race where she competes against Oguri's untamed speed, March's confidence begins to falter. Meanwhile, Oguri undergoes a transformation after facing off against March, as a spark of ambition ignites within her for the first time, inspiring her to strive for more than the limits of her hometown and to reach the grand stages ahead.
