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 which renders him unable to use his Mangekyō Sharingan and resulting in him losing his Rinnegan's six tomoe for an extended period of time.
