After forming the needed hand signals, the user forms a well of metal in front of them and makes it erupt from the ground in the form of a large wall. Though the metal is mostly iron, chakra can be added to it to increase its strength and durablity. The height and thickness of the metal wall depends on the user's chakra level. This wall was shown to be strong enough to take the impact of a Wind Release: Rasengan and a Chakra Enhanced Strength-augmented punch. It can also liquidize and trap and opponent's striking limb.
