Space-Time Ninjutsu

Jikūkan Ninjutsu (時空間忍術; Literally meaning "Space-time Technique") 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 near instantaneously.

All summoning-based techniques are space-time manipulation related, as they warp the targets through a dimensional void to the summoner's location.
