I Just Wanted a Quiet Life... So Why Am I an Uma Musume Trainer?!

“The world is always wrong.”

After surviving high school with my cynical wit and a complete lack of romantic progress, I—Hikigaya Hachiman was ready to live a peaceful, uneventful life.

No youth, no drama, no forced social interaction.

That dream came to a crashing halt when I somehow woke up in a world where horse girls—yes, literal girls with horse ears and tails—race professionally while chasing their dreams.

And apparently… I’m now their trainer.

Me. The guy whose idea of teamwork is "doing everything myself to avoid dealing with people."

Special Week smiles at me like I’m her hero. Tokai Teio asks for advice like I have wisdom. Mejiro McQueen demands a training plan like I know what I’m doing.

Spoiler: I don’t.

But every race pulls me deeper. Every tear, every laugh, every finish line crossed… I start to understand these girls.

Maybe... just maybe...

This world isn’t as wrong as I thought.

A loner, a realist, and a former Service Club ghost becomes the heart of a new team.

This is the story of how I, Hikigaya Hachiman, became the most reluctant—and possibly the most effective—Uma Musume trainer this world has ever seen.
