~MYTHOLOGY~
Mythology? How can there be mythology within the lives of these senshi? Well Naoko took the time into actually making these characters have some detail in their life.
Why is lead crow lead crow?
In myth, Coronis was the mistress of Apollo (another reason why she may have red/orange hair) But before she had one of Apollo's kids she had cheated on him. And thus creating Raven. Raven told the secret and the god was furious. He killed Raven burning her in a pyre. That 's how she got her black wings. Before, Raven had white wings. So this meaning. Sailor coronos was white or white magic, or something along the lines of that.
OR - the idea that she was a daughter of some king. And in order to escape from Neptune. She was turned into a crow by Athena.
