Saigōgan

Note: The usage of this technique in general roleplaying is currently being mulled over.

An advanced technique of nenzuru, it allows the user to overtake the target's mind completely and let t "flow" out of it's borders, essentially spreading across the whole body, including the nervous- and chakra system. This allows the user to perceive hos the victim's chakra system works, allowing them to replicate any technique of the victim, even Kekkei Genkai, and use it as their own. Using these replicated techniques, however, requires an unusually large amount of mental energy to replace the physical and spiritual energy needed to form chakra, tiring out the user rapidly than the original one. To use this method, both the user and the victim have to sit still for a long time, depending on the complexity of the victim's brain and their abilities. It also requires a device similar to that one used with the Yamanaka version of Mind Reading. The mental strain that accompanies the technique is mostly fatal to the victim, unless he or she is freed before the jutsu is completed.

However, Sushun has shown a more battle-useful variation of Saigōgan, albeit less effective. By holding the victim for a while, the user can perform his opponent's abilities as long as he physically touches them. This also includes Kekkei Genkai, seen when Sushun's eyes took the shape of a Byakugan when he grabbed a Hyuga clan member by the throat. It also allows the user to know and understand all of his opponent's abilities, aswell as understand the full workings of their mind, robbing the opponent of any chance to surprise the user with a supposdly secret technique.

Trivia

 * Ths technique was partially inspired by the Perceptive Replication Ability of Heroes.
