Infinite Tsukuyomi

This technique is the key to Madara's Eye of the Moon Plan. It creates a white world under Madara's control, where he can create and change everything as he likes, using the power of the Demonic Statue of the Outer Path. To catch every human being in this genjutsu, he plans to reflect it on the moon's surface using the eye of the Shinju. To gain enough power to do that, he needs to become the Ten-Tails' jinchūriki.
