Yomotsu Hirasaka

The user is able to form rifts within the fabric of space that allows them to instantaneously transport themselves to different locations. They are also capable of sending different sections of their body forth by partially entering through the portal. Furthermore, they can use the portal to catch the enemies off guard by creating rifts behind them, and sending them to different dimensions. This happens so quickly that even Sasuke Uchiha, a shinobi capable of instantaneous teleportation, was unable to evade it. It has been shown, however, that evading the portals is possible.

Trivia
