Earth Release: Earth Spear


 * Name:
 * Type: B-rank, Supplementary
 * Users: Kakuzu

This is a ninjutsu technique utilized by Kakuzu via his earth-element heart. This technique makes use of the chakra that naturally flows through the body, using earth elemental manipulation on it to harden the user's skin. The hardened skin is nigh-unbreakable and can be used to defend against physical attacks as well as strengthen offensive strikes. The technique is also weak to the lightning element.
