Limited Tsukuyomi (Sigma)

The  is a advanced version of the Tsukuyomi, and a downgrade of the Infinite Tsukiyomi. However, while labeled as a downgrade, has shown great effect.

Overview
While using the Sharingan, the user has the ability to reflect their eye off of the moon. After someone is caught in this world, they are all trapped in a genjutsu world were everything seems to be reversed. From events, places, and further even history. Everything in this world is practically real, only acting as a "alternate" world.

Countering

 * People who are sleep, seem to have no affect. As they can't see the moon's shape.
