Space–Time Ninjutsu

are techniques that allow the users to manipulate the space–time continuum.

Usage
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 no other technique can access. However, if techniques of different dimensions are similar in nature, 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.

Dimensions

 * Kamui's Dimension
 * Kaguya's Dimensions
 * Pure Land

Trivia

 * In Naruto the Movie: Legend of the Stone of Gelel, Temujin summoned a distortion in space-time using his blood to activate the contract in the Sealing Room. However, the civilians of Temujin's Continent do not know what chakra and ninjutsu are, this remains debatable whether it can be counted as an actual ninjutsu.
 * Though summoning of ninja tools is commonly associated with the use of the Unsealing Technique, some shinobi have shown the ability to use space-time ninjustu to summon objects.
