Rejecting her grandfather's request to study medicine and inherit the clinic, and with the support of her father and mother, Chihiro Higashino resolutely forgoes further studies and embarks on the path to becoming a central trainer, heading for Tokyo. Here, the strongest horse racing girls from across Japan gather to pursue their dreams. Aiming for the Shining Series, they sign contracts with trainers they find a good match for, striving together for victory. In such a competitive arena, what kind of horse girls will Chihiro Higashino meet, get to know, and become close friends with? What kind of stories will unfold between him, her, and the rest of them?

Inari Kagura, a young girl from China who died from overwork, had just awakened in a remote shrine and, after a desperate escape from a sudden fire, collapsed on the doorstep of the Symbol family. Lacking the system unique to time travelers, she was penniless, powerless, and lacked even a usable identity. Her body, now only eleven years old and too timid to accept a part-time job, forced her to accept the old Symbol family's offer of a maid position to survive. "This world isn't right. I should have listened to my bestie and gone to see Uma Musume..." In the student dormitory in Tresen, looking at herself in the mirror, now transformed into a ponygirl, Inari Kagura sighed helplessly, feeling uncertain about her future. On the bright side, at least a maid's duties didn't involve any strange tasks, nor did she face the kind of shrewd young masters who would demand your services by name. "Ms. Eclipse, I think people should still look up..." Looking at the words that suddenly appeared out of thin air on the mirror, Inari Kagura felt even more complicated. And, is there really nothing?

Chiya Fujiwara, as a trainer of Treson, fell into a huge blow after being terminated by two race girls in a row.

"Isn't there a racehorse girl who is both obedient and understands my heart? With

unrealistic fantasies, he made a wish to the three goddesses.

The next day, his wish came true.

But, ah.

Looking at the white-haired and blue-eyed girl next to her, Fujiwara Chiya held her head.

"Why is this person myself!

"Why is this person myself! Two

people make the same sound.
