@eras: The Setsura actually resembles a hand any way I look at it. The tube is the fore-arm and palm. There are the energy claw emitters that look like fingers and stuff... so yeah... upgrades or make it look more natural.
Though I find it odd that we're always out to hurt/maim/torture/in-born disabilities/even kill out characters but we never give them disabilities as the story goes along
just sayin'
