|Earth Grudge Fear|
Earth Grudge Fear (地怨虞, Jiongu) is a technique that transforms the user's body into something similar to that of a rag-doll's, which is held together by hundreds of thick black threads. Kakuzu is able to manipulate these threads for many purposes.
In addition to manipulating threads, Kakuzu has animal masks that are sewn onto his back, granting him numerous elemental affinities. He can detach these masks and have them take on a body of their own, composed entirely of threads. These masks are capable of attacking separately, unleashing devastating blasts of elemental chakra. These masks can also have the masks move from his back to his head, allowing him to fuse the attacks of his masks together in order to increase his attacking power.
- In the Naruto series, this technique is classified as a kinjutsu.
