That is some really good metal the umbrella is made of. For it to dual as a rapier-like stabbing attack, and a sabre/machete-like slashing attack, all while being completely fine to shoot is impressive, because it implies it's somehow that light. More that, it's much more likely this girl is an absolute badass at fighting because it's not easy to move so accurately AND quickly.
She neck-stabbed a guy in what, like under one second?
DO YOU EVEN KNOW HOW HARD THAT IS? (I play foil and occasionally epee in fencing, for reference. Neck touches are hot, and everybody in my team claps when it's achieved.)
