Kūkan chōyaku

Kūkan chōyaku(空間跳躍, Space Jumping) is a Space-Time Ninjutsu created by Namikaze Sasuke during his stay in Uzushiogakure. This works by creating a wormhole that connects two points in space no matter the distance, allowing Sasuke to transport himself instantly to a desired location. This however is restricted to his line of sight, or places he has been to before previously. He may also use the chakra signature of someone he has encountered before as an anchor for his teleportation. Sasuke is also able to teleport other objects along with them, which puts strain on his body depending on the size and weight of the object. When teleporting people, it incites nausea if they aren't used to it. After teleporting, Sasuke leaves a sort of rift in space-time that resembles a trail of translucent smoke that dissipates several seconds later. These rifts will shred anyone or anything that attempts to touch it, ruling out the possibility of someone pursuing generally. It seems that large doses of foreign Raiton chakra will prevent him from using this ability.
