Shin Uchiha's Space–Time Dōjutsu

With his Sharingan, Shin has access to a unique space–time ninjutsu. Being drawn inwards to a spiralling void focused on his right eye, Shin is instantaneously transported to virtually any location of his choosing.

This is done by generating a spatial barrier, that warps anyone and anything within its confines. It can even effect chakra-based substances. To fit the situation, the spatial barrier's size and shape can be manipulated at will. Shin is also able to channel the usage of this technique through his Sharingan Spying Creature. Doing so allows Shin to plan for a strategic retreat should the need arise. After being temporarily incapacitated by Sakura's sneak-attack during his battle with Sasuke and Naruto, the creature was able to rescue its master while kidnapping the former before any of the latter could react.

Space–Time Ninjutsu

Space–Time Ninjutsu (Jikūkan Ninjutsu, English TV: Teleportation Ninjutsu or Transportation Techniques, Literally meaning: Space–Time Ninja Techniques) are techniques that allow the users to manipulate the space–time continuum.

By manipulating a specific point of space, the user can warp anything targeted into a dimensional void and teleport it to another location instantaneously. Minato Namikaze, Obito Uchiha, Sasuke Uchiha, Kakashi Hatake, Tobirama Senju and Kaguya Ōtsutsuki are skilled users of space–time ninjutsu. All summoning-based techniques are space–time manipulation related, as they warp the targets through a dimensional void to the summoner's location. Space–Time Ninjutsu allows one to bypass any Barrier Ninjutsu, as barriers only extend over the dimension they are placed upon, which cannot prevent Space–Time Ninjutsu users from escaping to the dimensional void and then back outside of the barrier's confines. It appears that each specific space-time technique has its own unique dimensional void that other techniques cannot normally access. However, a user can synchronise their respective dimension with the other one to gain access to it. To achieve this feat, however, requires much more chakra.
