A long time ago, before humans were created. Two sister, light and dark, both very different from each other. The youngest one saw peace and happiness in the world. But the eldest one saw darkness and betrayal. Two sister, light and dark, fought to win the war they brought. But failing to see their own fault, they kept on fighting, for centuries long. Now it's 2017, the war is still going. But when a curious angel comes to earth, all would be changed........... ........forever.
