I'm a Lover Not a Fighter, But I Will Fight for What I Love

Michael is the oldest angel in existence. Logically there has to be a youngest somewhere. Enter Azariah: the baby of the celestial family. Trained and loved by the legendary Castiel, she's a powerful soldier with a tough exterior and a heart of gold. But don't mess with her unless you want to be strangled by your own intestines.
