Water Release: Anthropoid Puppet Theatre

After using Water Release: Yama's Judgement to take complete control over a target(s) bodily fluids that contain water, including their blood, which they can then use to override and control the motor functions of the target against their will. Shūrin can make his victims do his bidding in a fashion similar to Puppet Masters using the Puppet Technique. The only difference being, Shūrin can choose to whether or not let his victim(s) retain their consciousness; though, it is hardly a factor, since even with them being conscious they are unable to resist this control unless his chakra has been flushed out of their system completely. It would seem that even if a small portion of his chakra manages to linger inside one's body, regardless of when this chakra was poured into them, Shūrin can immediately take control of at least parts of their body. The degree to which he can manipulate the bodies of his victims depend on how much chakra he pours into them.

Trivia

 * Yakedo Gesui's body only retained a small portion of Shūrin's chakra due to chakra deterioration over the course of 24 months but despite this, he had enough of Shūrin's chakra left in his system for Shūrin to take complete control of his right arm.
 * It would seem that despite its name, this technique can be used on any living being, as Shūrin was able to use it on a bunch of rats.
