Dungeons are a place where danger lurks everywhere, a place where mana would gather and birth monsters where brave people can test their strength and braveness. Adventurers are people who dedicate their life to knowing the dangers of the world and the Dungeons itself. With fame, gold, and cheers from the people who would not want to be an adventurer. These two things are something that can't be separated no matter what you do. Now how can a simple blacksmith fit into this. In this world full of magic and swordsmen. 

Watch how Yuuto, a blacksmith, will discover the world he is not able to see while stuck in his town. Can he survive or die before he even managed to see the wonders that have been secret to him.
