I am serious but crack jokes to lighten the air.
I have a katana on my back, one on my side and a dagger on the other. I have a small container on my leg that contains shuriken in it.
The reason for the scar on my arm is that I got into a swqord fight a long time ago. He cut my arm off during the battle and then ran, leaving me in my own blood. Someone came along and saved me from dying, he had a metal arm replacing that missing arm with a metal one. I need to find that man and get my revenge.
