As a Uma Musume player, he never imagined he would one day become a Uma Musume himself. His first day as a Uma Musume: "Uma Musume bodies are beautiful and smell wonderful, I'm so cute!" Three years later: "Paper dolls don't matter, I just want to win!" A mutation in the game granted the player a Uma Musume body, even allowing him to travel to the Uma Musume world and be reborn as a Uma Musume in another timeline! Thus, in future races, people might witness the following scenes: [Mejiro McQueen meets Mejiro McQueen, and is dominated by the terrifying Great Escape!] [The indomitable hero, the Emperor of the East Sea, meets the ultimate emperor who surpasses even the emperor with his undefeated triple crown!] [The golden ship from Mars meets the demon ship that can turn races into a severe delinquency arena!] And all of this begins on this morning, when the player becomes the Uma Musume Mejiro McQueen!

【Multiple Heroines】Just because I answered the question of a gentle older sister in my dream,

When the young man on the hospital bed opened his eyes again,

The girl who was being introduced to the other side with her beautiful tail wagging while being held by her mother's hand,

"From now on, he will be your trainer and she will be your horse girl."

Eh? Eh——!!!!!!!!!!!!!!!!!!

I'll be writing some original overseas plots, so please bear with me. Since this is fan fiction, of course there will be some changes to the plot! Please bear with me on that as well. As a new author, I'll do my best to write something that everyone will enjoy and be satisfied with.
