A masterless swordsman from Tosa who made his name practicing the Hokushin-itto-ryuu style. He's best known for his sharp criticism of the shogunate and especially the Shinsengumi—though he keeps his distance from actual rebel groups, preferring to stay independent. Fans often note his peculiar way of speaking, which matches his unconventional approach to everything else. Unlike most swordsmen of his era, he carries a Smith & Wesson revolver as his weapon of choice. He knew Tetsu's father back in the day, which explains some of his connection to the story.
