Eizo Tanya is now living a quiet life as a blacksmith in another world. Well, maybe not so quiet... Tales of his cheat smithing abilities and overpowered blades have started to spread. Alongside his companions, Eizo tries to earn a modest living while avoiding political intrigue. However, intrigue finds him anyway when he saves Diana, the daughter of a comital family.

When an elven village requests that he repair their treasure, a mithril sword, Eizo is excited to take on the challenge. But will this blade be too much for a human blacksmith to handle? Eizo puts his cheats to the test, repairing both swords and societal conflicts, all in pursuit of his dream life!
