Umamusume in the history
The gray-haired umamusume was an exceptionally great horse, fast on her feet and unfazed by the hustle and bustle of the battlefield. Legend has it that she rode 50 miles in the morning before taming, and 80 miles in five hours of after-dinner exercise. She is said to have run through many battlefields despite suffering eight battle wounds on her small body. (according to wiki)
