The most powerful girl who does not know common sense throws herself into the battlefield -- a girl with silver hair floating around and with jet-black eyes galloping across the battlefield. The name of the girl who carries a jet-black sword and kills many enemies with an innocent smile is Olivia. She is a girl who has a wide range of knowledge and combat skills and has been driven into the existence of a god called Shinigami. On the day Olivia turns 15, Shinigami suddenly disappears. Seeking a clue, Olivia decided to devote herself to the war as a volunteer for the Royal Army. Time was 1998. The kingdom was forced to struggle against the empire that claimed victory over the continent. On the increasingly fierce battlefield, the innocent girl who does not know common sense takes the path of a hero as the "strongest piece."
