There's not much I can say about this obscure character right now so I'll just explain the basics the best I can.

He resides on a post-apocalyptic Earth approximately one hundred years in the future. He is a mercenary nomad and so spends a great deal of his awake time, when not hunting for food, looking for work. Firearms are incredibly difficult to come by in this barely forgiving world, let alone a hearty supply of ammo for said firearms, so he prefers to carry a katana with him instead when performing his duties.

Law, government, pretty much any traits of a civilized world are non-existent here. The only sure rule to abide by in this future Earth is that everyone has to fend for themselves even if it means taking the life of another. So because of this, he trusts no one and will only take up a job offer if he's sure the reward is well within his favor.
