No she should be wearing what ever makes the story exciting. The only reason it stands out is because retards like you go "HUR DURR NOT REALISTIC." It's not supposed to be realistic. She's a pretend ninja with laser swords that come out of her hands. The same reason they get fucking mutilated when they go into battle is the same reason every other TVshow or piece of fiction doesn't. Because it's not that kind of edgy twat story.
