The TV anime series is set in a futuristic, yet feudal Japan, and stars a samurai named Afro for his hair. The story follows Afro as he tries to avenge his father's murder. In the world of Afro Samurai, it is said that the one who becomes "Number One", will rule the world, wielding powers akin to a god. Someone becomes Number One by killing the previous Number One and taking his ceremonial headband. However, the only rule in this world is that only the "Number Two" (also designated by a sacred headband) is allowed to fight the "Number One".
