The Angel On The Battlefield

[This is an original; I just don't want contract spam for it so I posted it here.] Serenity Dawson is a girl hunted by millions all because of a rumor. Died from having her heart torn from her chest, and she was reborn into the past before the appearance of Fana. How will she live her life this time? Will she help those in need once again, only to be betrayed all over again? Or will she turn from the Angel she was hailed as in her early days into a demon?
