A king has left the world. In this country where for generations the king has been decided by a holy sword, a ceremony would be held to select the new king. Many people take the challenge -- only one person was able to pull out the sword.
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 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. Weeping as she holds the holy sword in her hand, wondering why she was chosen. The girl knows love. 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.
