Delate, a blacksmith at the Blacksmith's Guild, lived a modest life, crafting toy weapons for the neighborhood children, all under his principle of "not working harder than necessary."

However, fifteen years later, he is expelled by a proud colleague who has become the Guild Master.

Expelled, and also having received a letter from one of the children, Delate heads for the royal capital.

There, he discovers that the neighborhood children have become "heroes"—a Legion Commander, the Chief Instructor of the Magic Academy, and the Captain of the Musketeer Corps—thanks to "those toys."

As the legendary master craftsman who forged their weapons, Delate begins to receive due recognition from those around him, being appointed as the national army's exclusive blacksmith and a special lecturer at the Magic Academy, among other roles.

Meanwhile, the Guild Master.

He attempts to repair a national treasure crafted by Delate but destroys it in a single second.

After losing his job, by order of Her Majesty the Queen, he is commanded to train under Delate.
