Sam's father was eventually killed by one of his pupils, with one of the drug cartels being rumored to have been involved for reasons and methods unknown, although not before Sam personally inherited his Murasama blade from his father.
His father ran a Brazilian Kenjutsu dojo, and specifically taught the Uradachi technique, better known as Satsujin-ken or 'the murdering sword,' which dealt with violence as the end goal.
Samuel Rodrigues was descended from a long line of swordsmen, dating back to 16th century Japan.
