Rakka:
We're not human, are we?

Reki:
Nobody knows exactly what we are... if we're human or not. We call ourselves the Haibane, which means 'charcoal feathers'.

Rakka:
I wanna go home!

Reki:
The Haibane are not allowed to go outside of town. It is our most sacred law. Besides, even if your family were somewhere in this world, they wouldn't recognize you if they saw you now.

Rakka:
But why?

Reki:
Just as you cannot remember the world that you used to be in, there is nobody in this world who can remember you.
