差し競馬無理に仕込まれて馬群が怖くてレースも嫌いになりかけてるところにカノープスの面々や南坂トレやイナリと出会って徐々に明るくなっていってレースで逃げたことがきっかけで今のターボになったんだよね（ここまで妄想）

Even though afraid of other horses, she was forced to race in the back of the pack, and was on the verge of hating racing. Then she met Canopus, Trainer Minamizaka, and Inari, gradually brightening up and breaking away from the pack, becoming the Twin Turbo she is today. (this is all a fantasy)
