Space-Time Ninjutsu Barrier

Space-Time Ninjutsu Barrier (時空間忍術結界, Jikūkan Ninjutsu Yūkai; Literal meaning "Barricaded Pocket Dimension") is an ancient style that allows the user to manipulate the space-time continuum involving barriers to temporarily isolate a certain location from earth. Basically the user creates a pocket dimension, which allows the user to become the “law” of the dimension; control and disrupt the time, sensory, chakra flow, etc. Around the pocket dimension is an impenetrable barrier, which allows one to enter the pocket dimension, while blocking the way out. Therefore the Space-Time Ninjutsu Barrier is regarded to be an absolute style, only honed flawlessly by a few, two of them being and Tenzu.

Shikon
While the ancient style is classified to be impenetrable, Shikon’s Space Time Ninjutsu Barrier is not blockading any trespasser to go in and out. His pocket dimension focuses to alter the sense of time and disrupt the chakra flow. This allows him to make his trespasser slower as he changes the speed of time, while it does not affect him. On the other hand, the farther the trespasser is from him, the closer they would be to the normal speed of Earth. The closer they are to Shikon, the slower the time will go for them. Disrupting the chakra flow allows Shikon to disable the trespasser’s ability to mold chakra and perform jutsu of any kind.
