Song Wen accidentally stumbles upon the world of horse girls and becomes a horse girl trainer. Having acquired the Cloud Raising Horse Girl System, he immediately intercepts Silent Suzuka, allowing her to escape the other horse girls and take first place in the competition. He then invites Ulala, Emperor of the East Sea, Mi Yu, and other horse girls to join his team. Silent Suzuka: The scenery ahead can only be seen with one horse in the lead!!! Ulala: The legend of a hundred battles and countless defeats will come to an end!!! Emperor of the East Sea: With the imperial dance, I will conquer the world!!!

After being transported into the world of Uma Musume, specifically into Tracen Academy, Kitahara Shinji has only one goal: to slack off.

When the chairwoman calls on him, he doesn’t respond. When the prestigious Mejiro family invites him, he ignores them. When the student council reaches out, he pretends to be asleep. And when a horse girl personally chooses him to be her trainer, he disappears without a trace.

"Let’s hope you treat your own life with the same level of commitment."

"Yeah, sure, whatever."

As he stares at the overwhelmingly red “monopoly of attention” stat in front of him, Kitahara keeps nodding, completely unfazed.

He’s convinced: as long as he slacks off hard enough, even the racetrack can’t catch him.

And surprisingly, he turns out to be right. As his reputation for being utterly useless spreads, everyone at Tracen Academy ends up believing he’s actually—

A walking mint for horse girls.

The chosen one of the Three Goddesses.

The guardian of Tracen.

The savior of all horse girls.

Kitahara Shinji: “…Huh?”

"Horse Girls" are born to run. They have "tails and ears" on their bodies and "superhuman running abilities". They are simple and kind "girls".

They inherited names and souls from other worlds, gathered at the "Tracen" Academy, and kept running in the "Shining Star Series", striving towards the finish line called "dream".

But such a road is destined to be bumpy.

If the timeline remains the same, the reed-haired monster who regretted missing the classic triple crown, the white lightning who was forced to retire due to injuries, the dark assassin who had a happy name but was not blessed... these will happen again.

After traveling to this world and becoming a trainer, Kitahara is determined to create a better world for horse girls.

"My biggest dream is for you to run carefree on any field."
