Uma Musume Pretty Derby - Her Highness's Days Off -Princess Holiday- (Doujinshi)

Several years after Fine returned to her home country, her former trainer learned about her arrival in Japan while visiting his regular ramen ship. As he reminisced about the old days, he suddenly heard a familiar voice beside him...
While he ascertained which parts of her changed and which parts stayed the same, his time together with the now adult Fine Motion passed, and thus began the 3 days of "Her Highness's Days off".
