This device is used by Shizune to launch poison-coated senbon at her opponent with deadly accuracy. It is comprised of a five-part segmented device with barrels on top where the senbon are loaded and soaked inside the barrels when the strings are pulled. Wires on the back of these facilitate the launching of the weapons. It is usually kept concealed underneath the sleeve of her kimono on her right arm.
