Heavenly Illusion: Perception Overload

This technique is reportedly Shirokaze Fuyutama's most powerful and original genjutsu is his arsenal. Using what he had learned from years of training with his Sharingan he developed a technique designed to debilitate even the most cunning of shinobi. This technique allows the user to alter the target's ability to sense external stimuli in a quite unique way. Under normal circumstances a person is unable to detect a stimuli until it has reached an intensity referred to as the absolute threshold. In this way a person is able block out unnecessary stimuli that would otherwise be distracting and preventative to accomplishing a focused goal. As such the body constantly sends a multitude of sensory signals that aren't registered by the brain. This technique effectively removes the minds ability to block out these sensations. As such a target under its effect has all of their senses magnified to the point that clouds their mind's ability to focus on anything but what they are sensing. In most cases this will immediately cause a target to fall into a comatose like state due to the mass of information that is being channeled from every single one of their nerves. It should be noted that the effects are only temporarily as the victim's mind will eventually reestablish the sensory limitations over to course of a twenty minutes, though time spent unconscious can be anywhere between a few minutes to several days. Particularly calm individuals, people who meditate regularly, and those who already have increased sensory abilities appear to have greater resistance to this technique. As such the only way to defeat this technique is to forcefully ignore the unnecessary sensory information. It would appear that skill with genjutsu doesn't provide one with a greater defense from this technique due to the its design. While this technique has a quite powerful effect it requires direct eye contact from a Sharingan user with great skill in genjutsu. Also Shirokaze states that he can only use this technique once every eight hours or three times every twenty-four hours. The latter reportedly stresses the user's chakra reserves and eyes, which is rare for a non-Mangekyou technique.
