The world is in a racial crisis. An alien race called "ghosts" launched a war with humans, and humans who once stood at the top of the food chain became food for the "ghosts". In a city in a distant continent, soldiers struggled to fight. The "Ghost Hunter" organization, the strongest combat force in mankind that has assembled many sharpshooters and possesses advanced weapons, has not yet come to this city. The soldiers could only use crude weapons to resist the "ghost" invasion. An unnamed soldier and his childhood sweetheart, Zi, protect each other in this desperate town.
Concept: alien war, tragic love, unknown hero
