In my quest for manga, I found this.
When Aya turned sixteen, all she wanted as a karaoke party with her twin brother and their friends. Instead she is attacked by her family, who are trying to kill her because they think she is a threat to the family. It turns out Aya is the descendant of an angel and carries her heavenly powers. Before long, Aya is on the run, accused of her father’s murder and hiding out with another of the angel’s descendants.
This first volume of the manga series is quite interesting. Some nice layout of plot and backstory. An early leader in the "angels are the new vampires" trend. Pick it up.
