The Hokkaran empire has conquered every land within their bold reach--but failed to notice a lurking darkness festering within the people. Now, their border walls begin to crumble, and villages fall to demons swarming out of the forests.

It is up to two young warriors, raised together across borders since their prophesied birth, to save the world from the encroaching demons.
