But then again, humans aren't much different. Anna, a normal village girl is dragged into this war at a young age when her village is attacked by demons. She manages to escape with a few others. The most unexpected people betray them, and others join them... some even fall in forbidden love. Will a few teens be able to stop this war? Or are they all doomed to a war that will last for eternity?
