Awataguchi Yoshimitsu made his name primarily as a tantou craftsman, but this tachi is one of his notable works. The name itself carries meaning—it's meant to represent "the only one" created within "one lifetime." He's the oldest of the Toushirous, and his younger brothers affectionately call him "Ichi-nii."
Most people know him by his consistently kind and calm demeanor, though he occasionally lets a sadder expression slip through—something fans have definitely picked up on.
