Sasuke Uchiha's Space–Time Dōjutsu

With his Rinnegan, Sasuke can use an unspecified Space–Time Ninjutsu to travel to different dimensions.

Usage
The technique creates a dark spiraling portal that people can enter with ease. With it, Sasuke can travel to Kaguya Ōtsutsuki's six dimensions, and Momoshiki Ōtsutsuki's dimension.

This technique requires a large amount of chakra, and extended usage leaves Sasuke incapable of using this technique, his Mangekyō Sharingan, and his Rinnegan's full power, for some time. Sasuke also stated that the number of people who could enter the portal was limited: only the four Kage and Boruto Uzumaki joined him on the rescue mission to save Naruto; however, they were secretly followed through the portal by two people.
