Kidōmaru spreads a network of "touch threads" throughout an area. Kidōmaru constantly sends his chakra along the threads, allowing him to sense anything that comes into contact with them; the threads are sensitive enough to even detect slight disturbances in the air. Because the threads appear no different than normal spiderwebs, they aren't likely to be noticed and thus are effective as an alert of approaching enemies. Kidōmaru uses this technique while he and the rest of the Sound Four are resting, ensuring they won't be ambushed. The touch threads, being stronger than wire, can also be used to reel in those who've contacted them.
