My Quiet Blacksmith Life in Another World. Volume 3

Eizo does his best to live a humble life, and the last thing he wants is to be caught up in political intrigue. But when he stumbles across a noblewoman in a precarious situation, he has no choice but to step in and lend a hand. This young woman turns out to be Diana Eimoor, sister of Marius, the city guard he's met many times. Shocked to discover Marius is a noble, Eizo agrees to help settle House Eimoor's succession by forging him a family heirloom sword. But danger lurks as Marius's brother launches a deadly plan to seize the countship. Can Eizo forge a sword sharp enough to cut through the treachery surrounding the fate of House Eimoor?
