Death March Parallel World Rhapsody (Manga) Vol 12

Elder Dohal and Satou stay up all night sweating over the anvil, taking turns hammering out mithril to forge the newly christened Fairy Sword Trazayuya! Between sword forging, spell book scrounging, and leisurely strolling around, there's always something to do in the Dwarven Kingdom! Yen Press
