About

The Gralca Empire—a military nation that once boasted the greatest strength on the continent. The Empire put into practical use the forbidden technology of mass-producing humans: the Combat Clone Soldier Project. With overwhelming numbers, they trampled over neighboring countries. These clone soldiers, who knew no fatigue, felt no fear, and offered absolute obedience to orders, swept across the battlefield as the vanguard of the Imperial Army. Nations fell one after another, and the unification of the continent seemed to be only a matter of time. However, the war dragged on beyond the Empire's expectations. The Allied Forces studied the tactics and weaknesses of the clone soldiers and established defensive lines. Furthermore, backed by abundant resources and economic power, they bolstered their armaments and gradually pushed back the tide of war. Meanwhile, the Empire fell into a severe shortage of funds and supplies due to the endless conflict. Weapon factories could not maintain their operation rates, and fuel and ammunition were chronically scarce. Even the clone production facilities, once thought to be inexhaustible, could no longer provide sufficient reinforcements. Still, the Emperor and the military high command refused to admit defeat. In a desperate attempt to turn the tide, they issued one reckless order after another to the clones and soldiers alike. Frontal assaults on fortresses. Long-distance invasions without supplies. Diversionary tactics with no expectation of survival. Suicide attacks against the enemy's main force. To reclaim lost frontlines, the Imperial Army continued to consume the lives of its soldiers as fuel. With detonators embedded in their necks, the clone soldiers were permitted neither retreat nor surrender. Fight according to orders, or die by explosion for disobeying them. Those were the only choices. A mass-produced soldier referred to only by a serial number. This is the story of one girl who has survived the jaws of death time and time again—.
