Shadow Binding Technique is a hidden ninjutsu of the Nara clan. The user materializes their own shadow and reinforces it, making it resemble steel. Then they seize the target's shadow and forcibly move it. The technique's power depends on invested chakra: with a sufficient amount of energy even a giant can be shifted. Combined with the Akimichi Human Bullet Tank, it turns an ally into a controllable weapon. Unlike the Shadow Imitation Technique, here shadows connect, but the target is not obliged to mirror the user's movements and retains freedom within the confines of its own body.
