"I was thrown out of the workshop as an 'outdated witch,' but what I was dyeing was the 'Royal Blue.' ~It seems the former workshop, which prioritized efficiency and mechanized operations, is now screaming in despair as the dye won't set properly, but that's no longer my concern~"

A craftsman named Erna works at a royal dye workshop, and is mocked as a "outdated witch" for continuing to preserve traditional techniques. One day, the new master who inherits the workshop dismisses Erna for being "inefficient" and begins mass production using machinery. However, they did not know that the most noble color in this kingdom, the "Royal Blue," was a miraculous hue that could only be born when Erna listens to the voices of plants and communicates with them. The dresses made at the workshop after Erna's departure fade miserably during the ceremony. A story of the fate of those who have lost sight of the "real thing," and the redemption of an honest craftsman who is finally rewarded.
