Sabo is twenty years old and makes a living as a tattoo artist, goes to college for social sciences, and volunteers at a children's shelter whenever he can. At the age of seven, he was adopted along with his brothers, Ace and Luffy, by a couple who could not have children and who had a great life. Even though he grew up without ever lacking anything, the boy still remembers the difficulties he went through before being adopted and that's why he never let money go to his head.
