A king has left the world. In this country where for generations the king has been decided by the Holy Sword, a ceremony would be held to select the new king. Out of the many people who sought to draw the Sword, only one succeeded. Neither a knight nor royalty, the person was an ordinary girl. Persuaded by the legendary magician Merlin, the girl begins to live as the king without understanding anything. It is there that she meets the Knights of the Round Table. The girl stands on a battlefield for the first time in her life. She grips the Sword tightly in hand, still not knowing why it chose her. Tears are in her eyes. The girl learns what love truly is. Even as several threads of fate entwine around and trifle with her, she will continue to love only one. And so, the girl takes the sword in her hand. To cut open fate for the one she loves.
