Amenominaka

With her third eye, Kaguya is able to focus the dōjutsu and instantly transport her, and those within a certain range of her, to a different dimension. The activation of this technique is activated and cast so quickly that even those affected by it are caught completely off guard, as there seems to be no warning prior to its use. Having been set to a different dimension, the presence of their chakra is completely erased in the normal world as well.

Kakashi states that Kaguya has the ability to literally rewrite all aspects of the dimension instantly, a phenomena he also compares to the creation of genjutsu.

Currently there have been three locations within the dimension:
 * An active volcano surrounded by a sea of lava, with a single tower on the side of the mountain.
 * An icy mountain with a large castle near the top.
 * A vast desert.
