The Hay Fever Pollen Mask (杉花粉口罩 Sugikafun Masuku?) is a special surgical mask from the Joketsuzoku village that was created to give the unhealthy a means of self-defense by enabling them to breathe a paralysis gas at their target while keeping themselves safe from its effects. Its name uses the Chinese characters for "mask" that specifically refer to a hygenic mask and the Japanese furigana for the word "masuku", the Japanese rendition of "mask".
