The story of Umamusume: Cinderella Gray follows Oguri Cap, a horse girl whose wild running style defies all common sense and who grows to be called a “monster” as she strives to become the strongest runner at Kasamatsu Training Center Academy, a school that teaches horse girls how to race.
If you need more horse girls in your life, Crunchyroll currently streams both Umamusume: Pretty Derby and its mini spin-off, UMAYON. Crunchyroll describes the main series:
This is a tale of a world where “horse girls”; with glorious names and incredible running abilities live alongside humanity.
Horse girl Special Week has moved from the country to the city to attend Tracen Academy. There, she and her classmates compete to win the Twinkle Series and earn the title of “The County’s #1 Horse Girl.”
