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?

Due to some accidents, the goddess brought her to the world of horse girls. Although she doesn't know what to do, she just needs to follow the goddess' disguised system, right? After being lectured by the goddess for a long time, the girl finally stepped onto the track, but... "Oh no! There was an accident with contestant 8's gate!" "He bumped into it!" "I'm so upset!" ==============[You have our genes, right?] Isn't that great? [Well...] ​​Hmm? After turning around, she saw several tall horse girls (relatively speaking). You...what do you want to do? "After all, Z-chan is an adult..." "It's legal anyway!" Don't come over here! ! ! ==============
