• Extreme Mayora: A fanatical lover of mayonnaise who puts massive amounts of it on every single food item. • Heavy Smoker: Never seen without a cigarette; he becomes emotionally unstable if a smoking ban is enforced. • Childish Rivalry: Very similar to the protagonist, Gintoki Sakata; they get into petty, childish arguments every time they meet. • Cool and Strict: The brain of the Shinsengumi who leads the strictly disciplined squad with Spartan words and actions as the Vice-Commander. • Strong Sense of Responsibility and Loyalty: Possesses a self-sacrificing spirit, willing to get his hands dirty to protect the organization, his comrades, and his benefactor, Commander Isao Kondo. • Awkward and Shy: Has more pride than most; even when showing kindness or concern, he hides his embarrassment by saying, "I didn't do this for you." • The Straight Man: While constantly jerked around by the eccentric squad members and weirdos around him, he is one of the few sane, common-sense people in the series. He loves his wife dearly and adores his son and daughter.
