Sasuke Uchiha's Space–Time Dōjutsu

With his unique Rinnegan, Sasuke has access to an unspecified Space–Time Ninjutsu that allows him to travel across different dimensions.

Usage
The technique creates a black and dark blue spiral portal that allows Sasuke and others to enter it with ease. By doing so, Sasuke can travel to Kaguya Ōtsutsuki's six exclusive dimensions, as well as Momoshiki Ōtsutsuki's dimension. However, doing so requires a large amount of chakra as he can only teleport a certain number of times before he is unable to use his Mangekyō Sharingan or his Rinnegan's full power, and thereby access to this technique, for an extended period of time. Sasuke was also limited by how many people he could allow to enter the portal, such that he was only able to bring the four Kage and Boruto Uzumaki with him on a rescue mission to save Naruto.
