Fear of Earthly Wrath is a kinjutsu secretly developed in Takigakure. It changes the nature of the user's body: instead of ordinary flesh, it is permeated by many black threads that serve as connective tissue.
These threads are universal. They pull the edges of wounds together, put torn-off limbs back in place, fuse nerve endings and muscle fibers so that the damaged part begins to obey again. The user can detach fragments of the body and move them separately, and then pull them back.
The technique also prolongs life. The threads allow extracting still-working organs from an opponent and implanting them into one's own body. Usually hearts are obtained this way. Several additional hearts can be kept inside, and death occurs only after all of them fail. Each such heart is secured in a beast mask sewn onto the back. The masks are able to detach, create a body out of threads, and use elemental attacks. The threads can gather into a spider-like form to connect different masks and carry out a joint attack. Thanks to the additional hearts, the user gains a large reserve of chakra, as well as affinity with the element of the shinobi to whom the heart belonged, which allows, with the right selection, the use of all five basic elemental transformations.
