I've been searching frantically for an animation series. I don't know the name and the only things I can remember is that is has: 12 or 13 episodes, anime like animation, a first episode with a character (a girl?) walking through the woods at night, and what seems to be angels fighting in the final episode. I also recall it being heavily violent with blood. Can anyone help me search for this series? I've tried multiple methods of searching for it, but nothing has come up yet. Please help.
