Gorō Masamune

A blacksmith with a forge in Kamakura. As a master swordsmith, his fame is so great that there is no samurai who doesn't know his name. Due to his workshop being a hideout for Tokiyuki, he is also close to Tokiyuki and calls him "Toki-bō."

Currently, he is no longer satisfied with making ordinary swords and is obsessed with creating unique weapons. He has a keen eye for recognizing people's strengths at a glance and excels in crafting weapons tailored to the skills of the user, based on his belief that "there is no sword that can make anyone invincible."
