Kuroninja Multiverse

The Kuroninja Multiverse is the place where the Kuroninja Series takes place. It was created by Kuroninja's Earth-0 Counterpart. Sayori is the most powerful being in the Kuroninja Multiverse.

Outer Multiverse
The Outer Multiverse is the farthest part of the Multiverse, and it represents alignment. It's ruled over by the Interdimensional Guardians. Here's how the Outer Multiverse's dimensions are arranged:

Astral Plane
The Astral Plane connects the Inner Multiverse with the Outer Multiverse. It's a vast, empty space with no gravity, featuring circular portals scattered everywhere that take you to outer dimensions.

Inner Multiverse
The Inner Multiverse features the Elemental Dimensions, the Mirror World, the Nature Dimension, the Shadow Dimension, The Void, and, of course, the Center of the Multiverse.

The Void
The void is a place used to connect the rest of the Inner Multiverse with the Center of the Multiverse. It represents neutrality and doesn't have anything in it except total blackness. If any matter from Chaos enters the void, it creates a Void Creature.

Center of the Multiverse
The Center of the Multiverse is a large cluster of universes. Each universe has some people who look the same. Most of these universes are labeled Earth-(number). An example is Earth-1, Kuroninja's universe. Because the Kuroninja series is rated PG or T, everyone is banned from entering or leaving Earth-30.

Earth 0 is at the very center.
