Kaguya's Dimensions

are a gathering of alternate spaces that Kaguya Ōtsutsuki has access to through the use of Amenominaka. The first dimension was first shown after Kaguya's resurrection. Wishing to not fight on the world that she viewed as her "nursery", Kaguya transported both Team 7 and Obito Uchiha to the mysterious world and over a widespread river of lava. 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. There are a total of six interconnected dimensions which she can teleport to by creating portals. Kaguya has the ability to travel between any of her six dimensions as she sees fit. The dimension were noted by Obito to be very far from each other and he had a hard time believing she could join these dimensions in an instant. Even so, Black Zetsu stated repeated usage of instant dimensional transfers with Amenominaka was starting to take a toll on her chakra reserves.
