Meet Nao Sakai. He's most likely going to be a drifter.
He's 19 and wields both a sword and a gun, though he only uses the gun when he really needs to rely on it. Otherwise, he's pretty good while handling a sword. Before the apocalypse, his father owned a rather large and famous dojo in which he learned some of his skills and then some. He's fairly strong, and stands a bit tall, just a little over 6'.
Nao tends to be stoic and keeps to himself most of the time, only speaking if he absolutely feels that he needs to or if he feels particularly attached to a certain person.
