Earth Grudge Fear


 * Name: Jiongu (地怨虞, lit. Earth Grudge Fear)
 * Type: Kinjutsu
 * Users: Kakuzu

This is Takigakure village's most prized forbidden technique that Kakuzu has taken with him before defecting. This technique turns the user's body into a rag-doll like body, held together by hundreds of thick black threads. Kakuzu is able to manipulate these threads for many purposes. He can detaching his limbs and manipulate them for long range attacks, as well as sew up any injuries that he suffers. He can also use these threads to sew up damaged bodies of others, as demonstrated with Deidara's arms and Hidan's head.

The most significant point of these threads are that they grant Kakuzu a form of immortality (though he declines to think of it that way). Aside from sewing up his injuries, he can use the threads to tear into a victim's body and steal their still functioning organs and integrating them into his own body, extending his life. Kakuzu usually uses this method to steal hearts from powerful shinobi, and he stores five hearts in his body, which means that he must have all five hearts stopped to truly die.

These hearts Kakuzu took from others are stored in various animal masks sewn onto his back, and they grant him vast amounts of chakra and numerous elemental affinities. He can detach these masks and have them form bodies composed of the a blanket of threads, and they can attack seperately, unleashing devastating blasts of elemental chakra.

Masks

 * Tiger-like mask: This heart has a fire-affinity and it takes on the shape of a demonic bear. Using Fire Release: Intense Pain, it can launch a destructive, explosive fireball.


 * Bull-like mask: This heart has a lightning-affinity and it takes on the shape of a deformed bipedal body. Using Lightning Release: False Darkness, it can launch twin bolts of lightning that can pierce through enemies.


 * Eagle-like mask: This heart has a wind-affinity and it takes on a strange four-legged body with thin wings. Using Wind Release: Pressure Daage, it can launch a heavily dense and high-pressured tornado that can blow away anything in its path.


 * Earth-mask: It is unknown what animal this mask is, as it wa destroyed before it could be seen, but the heart has an earth-affinity. It allows Kakuzu to harden his body with Iron Body, which forms a near-invincible defense, and using Earth Release: Earth Spear, Kakuzu can further use this hardened skin to strengthen his strikes.


 * A water-affinity based mask and such techniques is never present, but since Kakuzu is from a waterfall based village, it can be assumed that his original heart (or a shinobi that did have such a heart, as his original heart might have died of old age) remains in his true body.
