"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."

"Surely, the world can't live without me?" "This ugly face is truly... disgusting." — A Thousand Years. This ninja world has been in chaos for a thousand years. Rotting corpses, blinding blood, and rusted, broken swords litter the battlefield. And the war... never stops. No one can end it. And now... he has arrived.
