He leads the third unit of the Shinsengumi as their captain—and he's the only one who's stuck around. Everyone else got executed for treason, which makes his position pretty unique and honestly kind of lonely.
The guy basically never talks. His silence has caused all sorts of misunderstandings, and people tend to find him intimidating without him really trying. When he does write something down, he ends every sentence with "Z"—which is apparently the sound he makes while sleeping. It's oddly endearing and weird at the same time.
Despite how things usually go, he's weirdly trusting. Case in point: he considers Katsura a good friend, even though Katsura is obviously shifty and duplicitous as they come. Fans often note this as one of his most defining contradictions—this quiet, solid guy who somehow has terrible judgment when it comes to people he cares about.
