Hi, I am trying to find out the name of an anime movie/TV show I saw as a child.
I vaguely remember that it was fantasy style, about a girl with wings and a boy.
She became leader of her people when she and the boy became one body when the stars or planets were in a certain alignment, and they stood together facing the sun or star and he raised his sword behind her as the sun shone on them to join them into one ruler of their people.
I only remember this much of the movie and I think it was near the end too.
Can anyone help?

That sound a kind of like "Sea Prince and Fire Child". Why don't you Google that and see what you come up with.
