Kawa Kamen - Skin MaskEdit
A semi simple technique used for covert ops operations. The user will literally peel the skin off of a dead person's face, and convert it into a mask. The user then temporarily bonds it to his own flesh creating a seamless mask. This disguise is usually supplemented by contacts, a wig, and some sort of voice changing technique. The mask lasts at most 3 days before it begins to rot off.
