Yomotsu Hirasaka

The user is able to form rifts within the fabric of space which allows them to instantaneously transport themselves to different locations. They are also capable of transporting sections of their body by partially entering through the portal. Furthermore, they can use the portal to catch enemies off guard by creating rifts behind them, even sending them to different dimensions. This can happen so quickly that even a shinobi as fast as Sasuke Uchiha is caught off-guard. However, evading the portals is still possible.

Trivia

 * The technique is named after the slope that leads to the underworld in Japanese mythology.
 * Black Zetsu gained access to this technique while he was residing inside Kaguya's severed arm sleeve, opening portals by channelling himself to the arm.
