My Quiet Blacksmith Life in Another World: Volume 4 (Manga): Volume 3

Eizo's back from the capital, Diana has permanently joined the family, and requests just keep piling up at the forge! First, Helen asks Eizo to sharpen her twin blades, and then Camilo commissions a custom rapier--one made of mithril. Eizo struggles to master this difficult ore, but the final product is sharper and more powerful than anything he's ever forged. However, this is frightening to Eizo, who doesn't want to see anyone harmed, and he finds himself agonizing over the bloody implications of his craft. As he wrestles with this, a new face appears on his doorstep: Lidy the elf! She brings along a shattered mithril greatsword, and asks Eizo to reforge the fragments and restore the blade. Can Eizo steel his resolve and nail the repair, or will the sword's magic prove to be too much for a humble blacksmith?
