Basically, there’s this manga I’ve seen on the Net sometimes, which is about a girl who stars living with her uncle (I can’t remember if he was one of her parents’ friends or a real uncle). I remember the front page has got an image in which these two are sitting and looking up the sky, fireworks maybe.

Fly me to the Moon and let me play among the stars...Yes, you have to, I am the child of the stars! Indeed, I am the child of the Sun and the Moon , after all.

I'm thinking Hirunaka No Ryuusei
