first off, thanks everyone for the awesome fanart!
Second, JBK, I'll have to add it to her bio page, since I forgot to put it down, but the power works kinda like if the space Kete and her umbrella occupied became void. Think of it like a Photoshop image, and Kete and the umbrella were cropped out of the image. So in that regards, when that happens, stuff would not be able to hit her, like rocks, or bullets, etc. And it only happens when the umbrella is open, and Kete is holding it. Hope that helps!
