Darius, a magical blacksmith, set up his workshop in a remote forest teeming with monsters for a certain reason. He was enjoying his freedom to forge, but one day, he found triplet girls abandoned in the forest and decided to raise them. As time passed, the daughters grew up healthy and strong. The lively eldest daughter, Aria, took the path of the sword. The intelligent second daughter, Luna, chose the path of magic. The kind-hearted third daughter, Sofia, followed the path of healing. Eventually, as his daughters set off for the royal capital to pursue their dreams, Darius gifted them with handmade weapons as a farewell present. ―Five years later.

His daughters had become heroes renowned throughout the continent in their respective fields. And at the same time, they were going around saying, “My weapons were made by Darius-sensei!” Thanks to his daughters’ boasting, Darius’s name spread throughout the kingdom without him even knowing it.

This is the story of a middle-aged blacksmith who was just quietly hammering iron, but thanks to his overly filial hero daughters, he unknowingly became a legendary master craftsman who shook the world without ever leaving the remote forest.
