Universal Travel Technique

The Universal Travel Technique is a Space–Time Ninjutsu created by Dark Soushiki Ōtsutsuki, which allows him to travel through different universes.

Overview
Not much is known about this technique, aside the fact that it took Dark Soushiki Ōtsutsuki many decades to fully perfect the technique. He focuses all of his chakra onto his hands and his Rinnegan and says the name of the technique before shouting "Open!", and a portal appears before him and as soon as he enters it, the portal disappears.

Usage
Dark Soushiki Ōtsutsuki is so far the only individual who can perform the technique, and with the fact that no one else even knows the existence of this technique, makes Dark Soushiki the only individual capable of using it. Dark Soushiki states that the universe he travels to is a "twin" of the universe he came from, and the events of said universe have followed the same path as the one he came from, or a similar one. Dark Soushiki's original universe had Black Zetsu killed by Asura Ōtsutsuki when he was still alive. As a result, this prevented Zetsu's plan of reviving Kaguya Ōtsutsuki from ever being completed as Dark Soushiki stated that Zetsu was the mastermind of the plan, and without him, Dark Soushiki would be unable to ever complete it.

Trivia
