why?
look how bout this excuse:
-you shot a man, in the face, from less then 2 meters away, with a bow, whilst the man didn't have any weapons on his person and was minding his own business.
It was self defense!
-how so?
Well you see he was so goddamn ugly that he nearly caused me to have a heart attack, so i had to act before i died, shooting him in the face was the only way..
-hmm yes i do see your point, he is much more bearable to look at now, with a mutilated face.
Just wait till i get my hands on them explosive arrows i ordered!
-WHAT ?
nothing!

also yes the katana is a knife! i mean its not a real sword! its not a heavy blunt piece of iron that you basically pummel someone to death with, using all the strength you can muster, it just makes a nice clean cut through most anything! what a sissy weapon!
i wonder if i'll get murdered for that... ohh look! a ninj....
