Shinobi: Sammy Sixgun

In a world of Ninjas, there stands a gun-slinging mercenary, "Sammy Sixgun"
From his hat to his boots, there's a reason the call him "Sixgun". They are the only weapon he'll use. From a Colt Model 1855 Carbine to twin Colt Army single actions to a boot knife made from a .38 special, six shots is all he needs.
Which might come in handy when he is to kill Akatski elites and figuring out his confusing relationship with Mia Hyuga. Hinata's cousin.
