Transmigrating to the world of horse girls, becoming a trainer, and obtaining a system. Each of these is a joyful experience, but when combined, it's triple the joy. I've even envisioned being intimate with a horse girl, having a baby girl, and a daughter becoming a Triple Crown horse girl, a future Hall of Fame horse. But why has reality turned out this way? Standing at the entrance to the arena, I look down, still able to see my toes, but not my entire paw. The horse girls all around me gather around me. Emperor of the East Sea: "Reiko, I will prove that Team Spica is the best!" Silent Suzuka: "Reiko, I won't lose, because I'm Silent Suzuka!" Mejiro McQueen: "Reiko, I will protect everything in the Mejiro family." Special Week: "Reiko, it's my duty to restore the glory of the foodie world." Excellent Quality: "Reiko, even if you target me, as long as I don't come in third, I'll be a success!" Wait, is there something strange going on here? Special Week, I'm not a big eater, why are you meddling? No, why should I, as a trainer, transform into a horse girl and stand on the track?

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! ! ! ==============
