She doesn't become a princess. She just has an unhappy marriage. Riliane never had descendants to begin with, as she became a nun before she was old enough to and lived her life at a monastery. The overall theme of the song is the girl trying to stay pure and believing she's failed solely because she didn't get the mirror, not falling into a demon's trap and letting it loose on the world. The child at the end makes her happy, indicating it's a good thing he was born. For her at least.

The only demon who has ever manipulated a fetus in-utero to look like itself is Eve, and she's not a demon but a powerful witch spirit. We know what the demon of pride looks like and it's not human.

There's no point where the four mirrors could have been in a shop for the girl to find.
