[Crossover] The Divine Child Never Shows Up

My name is Fujiwara Fujihime. It's a bit of a mouthful, but that's not the point. The point is that my name is Fujiwara Fujihime, and I live in a country called "Kyo," where everyone is waiting for the Dragon God's priestess to descend. That's right, I'm the princess of the Star Clan, the daughter of Fujiwara no Michinaga's mistress, and Fujihime, the "attendant" who summons the heroine's priestess and provides her with food, clothing, lodging, and transportation in the classic, famous otome game later adapted into a manga and TV anime, Haruka O Sora. Now I've run into the most difficult and terrifying problem of my fifteen years of life. Five years ago, I summoned the priestess right on cue, following the plot to the letter. The priestess answered my call, but five years have passed and she still hasn't made it to Kyo. And Kyo can't hold out for another five years. So, if the priestess has gotten lost in the passage through time and space, what should I, her summoner, do? Help, it's urgent.
