Kidōmaru used this technique to harden the golden metal that releases like sweat. The weapons created from this process form the core of his style of fighting. This metal hardens like steel upon contact with air, so by chewing it in his mouth and changing its shape Kidōmaru can create weapons appropriate to each battle. Because it instantly hardens, direct attacks from a distance are possible.
