The user uses chakra to harden their hair and shape it into spikes, which are as sharp as metallic weapons. This hair also grows long enough to wrap around them, serving as armour. This technique is used to discourage opponents from attacking, or it can be activated in response to physical attacks they've already started, causing them to impale themselves on the spikes. This blocks 2 techniques of B-rank, 1 of A, or 4 of C-rank before the hair loses its hardness and falls off reverting to the users normal length.
