Murata Tetsuya was an Edo-period swordsmith best known for crafting the Benizakura, a bio-mechanical sword that built on his father's original design. He came from a family of skilled smiths—his father was the renowned Murata Jintetsu, and he had a sister, Murata Tetsuko, who could confirm details about his work.
Tetsuya dealt with severe hearing loss, which affected how he communicated; he had a tendency to speak loudly, almost like he was constantly shouting. Despite his hearing difficulties, he maintained his craft and his connections in the underground weapon trade. He supplied Takasugi Shinsuke with one of his swords, though he wasn't particularly invested in or supportive of Takasugi's larger ambitions and schemes—it was more of a business arrangement than an ideological alliance.
