A loyal samurai, who has shown to sometimes go a little too far in the name of the empire.
After one too many foul-ups, the head of the family decides to send him into the Hammers. He tells them it is to help the empire, but in reality, it is just to get him out of the house. He needs to bathe, amongst other things.
The head of the family uses his contacts in the Hammer to secretly give him light-hearten missions, like escorting privileged individuals, children, etc.
His stamina makes for excellent person to take care of the needy, like children. Unlike other adults, he can keep up with the kids.
