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

Cynicism was my shield. High school left me wanting nothing more than solitude—no meaningless youth adventures, no romantic entanglements, no tedious social obligations.

Then I woke up in an impossible world.

Horse girls. Literal girls with equine ears and tails, competing as professional athletes, pursuing their dreams on the track. And somehow, I—Hikigaya Hachiman—have become their trainer.

A role I'm completely unqualified for.

Special Week looks at me with absolute faith. Tokai Teio seeks my guidance as though I possess answers. Mejiro McQueen demands training schedules from someone who barely understands the sport.

I'm winging it entirely.

Yet something shifts with each competition. The victories and defeats, the tears and laughter, the crossed finish lines—they reshape how I see these girls, and perhaps, how I see myself.

The world I once condemned as fundamentally broken begins to look different.

A detached observer and self-proclaimed realist reluctantly becomes something unexpected: the anchor holding a team together.

This is how Hikigaya Hachiman—misanthrope, reluctant trainer, and accidental catalyst—transformed into the most unlikely, undeniably effective Uma Musume trainer the world has encountered.
