Hetalia Hearts

To hold a weapon of greatness, but ruin in his hand. The superpower didn't know what to do with it. Until shadows invade their world, and he had no chose but to fight. All meaning of being a hero is gone. The darkness closes in, and he doesn't know what to turn to. He's trapped in his own mind. In the dead of night, running to a sun rise. What will become of his home & friends now?
