Infinite Tsukuyomi

The Infinite Tsukiyomi is a technique which is the key to Madara's Eye of the Moon Plan. It creates an empty dimension under the user's control, which can be then filled with contents of his desire, using the power of the Shinju to do so. To trap every human being in this genjutsu, it has to be cast onto the moon's surface using the eye of the Shinju. In order to do that, one needs to become its jinchūriki. The technique is done by assimilating a person into the Shinju. Once this is done, the person is locked in a permanently genjutsu yet will live endlessly from the Shinju's power.
