Eizo's business is booming, and his weapons are flying off the shelves of Camilo's shop! As the forge increases output, it's soon apparent that the family's handcart is no longer an adequate mode of transportation. Luckily, Camilo has a solution for sale—enter Krul, an adorable drake who's champing at the bit to be of service! With Krul pulling the cart, the trips to the city are a breeze...until the family is ambushed by a mysterious woman seeking to commission a blade from the blacksmith of the Black Forest. Eizo is shocked to learn that his new client is actually a demon, but he's even more shocked to hear what kind of sword she wants: a katana! Can Eizo forge an authentic piece of his culture in his new world? Or will cutting corners with his cheats dull the edge of his Japanese blacksmithing dreams?
