Yōkai

 Yōkai is a powerful Sharingan dōjutsu that gives the user access to a unique space–time ninjutsu.

Usage
Using their right eye as the medium, the user creates a spiralling void the he/she is drawn into. With this technique the user can travel almost anywhere including other dimensions such as the dimensions of the Rabbit Goddess. This achieve by creating a small spatial barrier that warps anyone and anything inside of it. Shockingly it can also warp chakra substances. Depending on the situation the user can alter the shape and size of the barrier, though size and shape require much more control and chakra usage.But if one has humongous reserves then he/she would be able to create massive barrier big enough to teleport even a village. This technique is often confused with the Mangekyō Sharingan's space-time jutsu Kamui.

Influence
Yōkai (妖怪?, ghost, phantom, strange apparition) are a class of supernatural monsters in Japanese folklore. The user chose this as the name because of it is the exact opposite of a god, which is what stands for.
