This technique transforms the user's body to something similar of a rag-doll, held together by hundreds of thick black threads. Kakuzu is able to manipulate these threads for many purposes. He is capable of sewing up any injuries that he or others may suffer. However, it appears that this is limited, since he warns Hidan not to move his head too much after he had sewed it back on, saying it might fall off again. He can detach part of his limbs and manipulate them, to the point that he can even send them underground, and then reattach them when he is done with them. 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 aspect of these threads are that they grant Kakuzu a form of immortality (though he declines to think of it that way). In addition to sewing up his injuries he can use the threads to tear into a victim's body, steal their still functioning organs, and integrate them into his own body, extending his life. Kakuzu usually uses this method to steal hearts from powerful shinobi, able to store up to four spare hearts at any given time (meaning all hearts must stop functioning in order for Kakuzu to die).

These hearts Kakuzu took from others are stored in various animal masks sewn onto his back, granting him vast amounts of chakra and 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 threads can also compact together to form a spider-like body around Kakuzu, allowing him to fuse the attacks of his masks together in order to increase his attacking power.

Masks
Kakuzu's animal masks, which resemble those of ANBU, contain his spare hearts. If he takes use of the heart for himself the masks crumble into dust.


 * Earth mask: It is unknown what animal this mask is, as it was destroyed before it could be seen, but the heart has an earth-affinity. It allows Kakuzu to use Earth Release: Earth Spear. In the anime, even though this mask was destroyed, Kakuzu was still able to use the Earth Spear technique.
 * Tiger-like mask: This heart has a fire-affinity and it takes on the shape of a demonic tiger. It can use Fire Release: Intelligent Hard Work. This mask can also unite with the Eagle-mask to launch a fire-wind dual strike that is near unstoppable.
 * Bull-like mask: This heart has a lightning-affinity and it takes on the shape of a some sort of deformed bipedal. It can use Lightning Release: False Darkness.
 * Eagle-like mask: This heart has a wind-affinity and it takes on a strange four-legged body with thin wings. It can use Wind Release: Pressure Damage. It can unite with the Tiger-mask to launch a fire-wind dual strike that is near unstoppable.
