Often slacks off by practicing badminton swings. He frequently goes on stakeouts and imposes a rule on himself to eat and drink nothing but anpan and milk.

Past: Before the Shinsengumi was formed, he was a militant punk who called himself "Mountain Zaki" and picked fights with Kondo and the others, but he ended up wetting himself in fear after seeing their practice swings.
