In Equestria, Twilight and her friends must go to Earth and become human in order to help Princess Celestia turn human again, and encounter several problems on the way.

Amu Hinamori is growing up. Nothing much in her life has changed since elementary. She's in high school now, the Guardians are back together and she and Tadase are even on-and-off dating. Amu has everything she could want. But it feels like nothing. Something feels wrong, something is stopping her from feeling happy with her life. Every night she finds herself looking out at the stars at night and wondering what Ikuto is up to. She hasn't seen him in 3 years, so now he'll be 20 years old and an adult. She wonders if he'll come back, then slaps herself because he's in the past and it's obvious he can't remember the promise. But then what is with these halucinations of seeing him out of the corner of her eye? And the rumours about the attractive cat-eared boy? What will Amu do when she finds Ikuto asking her for help and pulling her back into the life she left behind in elementary school?

It's been three years since Ikuto took his journey in searching for this father in America, leaving Amu behind with only a promise to hold to. Will that be enough to satisfied her loneliness.
