A Girl Is A Gun

I always imagined the owner of the this weapon was a young teenage girl who heavily modified an old fashion shotgun that she received from her father as a gift before the war. An EMP took down all of the worlds resources and started toxic war, killing millions of people. She was one of the only survivors but she couldn't save her father in the end, the girl trust no one and has grown bitter from her surroundings and experiences. She can never live a regular teenage life ever again but she still clings to the innocence of being a normal girl which reflects onto her weapon, even after years of looting and killing.
