Tetsuya Murata

Murata Tetsuya was a swordsmith living in Edo. He was the son of renowned swordsmith Murata Jintetsu, and brother of Murata Tetsuko. He was the creator of the Benizakura bio-mechanical sword, which was based on his father's original Benizakura, as confirmed by Tetsuya's sister in Episode 59. He had severe hearing problems and often spoke like he was shouting. He helped Takasugi Shinsuke by providing him the sword he had made but didn't care for Takasugi's plots or ambition.
