Space-Time Gate

The Space-Time Gate is a Scientific Ninja Tool, created by Amado, in order for Kara's members to instantaneously travel to and from their main hideout and in between various locations. They are also able to use this gate to transport large objects. When in use, the gate violently surges with electricity.
In the anime, after Boro's death, Jigen ordered Delta to destroy the base of the Ōtsutsuki Cult, alongside the gate there to ensure no one could use it.
After Isshiki's demise, Code disabled or damaged all working gates to prevent anyone from using them to access the organisation's dimension.
