Aside from the fact that there's a crow that can somehow speak, the boy Ron was living a completely unchanged life. He spent his days simply watching the distant starry sky, letting time pass by.

Then, with a sudden deafening roar, an unknown craft crashed into his backyard. In front of the stunned Ron, a girl who looked like she stepped right out of a picture book appeared with a flourish.

"You are said to be the hero of my star."

Confused beyond belief, Ron was, in a way, kidnapped and taken to a star completely different from Earth.
