Description: Kakuzu will imbue one of the three basic elemental chakras (Earth, Wind and Water) into all of his dark threads related jutsu (for the next five turns) to cause them to take on a specific set of properties. If the user channels their suiton chakra into the threads, they will become coated in a thick layer of adhesive water (similar to Water Release: Starch Syrup Capture Field), giving them adhesive properties and the ability to stick to people/objects. They will also become extremely resistant to burning and will short-circuit electricity, meaning electrical currents can't be channeled along them. This is because unlike normal suiton, the adhesive water is so viscous and dense that it resembles oil more than it does water, therefore making it an electrical insulator. The method employed in channeling suiton chakra is similar to that of a spider creating silk from its glands, where he will secrete the adhesive suiton chakra onto the threads as they leave his body, which is why the user isn't stuck to the threads internally. If the user channels their doton chakra into the threads, they will take on a pitch-black metallic sheen and be hardened to the extent they can clash with swords and endure powerful impact forces. This doesn't hinder the user's mobility in the slightest as the extremely high flexibility of Kakuzu's threads cancels out with the hardening created by channeling doton chakra. Granted they become more stiff and taut, but this simply makes the threads more tensile rather than unmovable. Furthermore, the hardening follows a similar method to that of Earth Release: Earth Spear, which hardens the skin without significantly increasing the object/person's mass. If the user channels their fuuton chakra into the threads, their cutting capabilities will be enhanced and electrical currents will be impossible to conduct along them. The jutsu itself doesn't add any damage or range to techniques used in conjunction with it. It simply serves the purpose of infusing the dark threads with elemental chakra to cause the technique to become an elemental jutsu of the same rank e.g. a B-Rank dark threads jutsu infused with doton chakra will become a B-Rank doton jutsu. Elemental infusions via this method will respect all elemental strengths and weaknesses of the infused element. Activating this ability is instant and does not consume any time whatsoever. All of these methods of infusing elemental chakra occur whilst the threads are leaving the user's body (to perform a technique), meaning they will have no negative effects on the user's body (e.g. causing them to become rigid due to threads clinging to one another).
