Yomotsu Hirasaka

Yomotsu Hirasaka is a kekkei mōra technique used by the Ōtsutsuki clan, which is said to be the progenitor of all space–time ninjutsu.

Overview
The user is able to open rifts in the fabric of space that allow them to instantaneously transport themselves to another location. The openings can be used to connect two different spatial locations within the same dimension, or to create a pathway that links two dimensions together. Kaguya Ōtsutsuki regularly used this technique to travel between her six dimensions. Using these spacial tears, the user is able to retreat, disorient enemies, or execute ambush attacks, among other possible tactics.

These portals can also be used to transport only sections of the user's body by partially entering them, allowing the user to grab their opponents and drag them into the portal, sending them to another location. The speed of this is such that even a shinobi as fast as Sasuke Uchiha was caught off-guard. However, evading the portals is still possible.
