In an ancient kingdom of El Gladio, all young men and women are given a chance to rise up in the world; from a farmer's field to the king's bodyguard, all through one mean; a sword.  A sword is what favors them; it is what unites them. Any who knew swordplay are fit to take up duties of a soldier. Any who mastered swordplay have their name spread far and wide, unsheathing their blade for the nobles, or even the royals. And any who- through a path of hardship and dedication- completely dominates the realm of swordplay, reaches the apex of legends.  But not all are equal... or at least that's what the world had decided for a certain young man, whose dream and ambition surpassed many others- yet are forced to wield those hopes with only a single arm.
