Madara planned this all. He want something from Kaguya's world.

The denial is strong...

Madara's plan ended with the Infinite Tsukuyomi. He thought he had achieved eternal peace, as he said to Naruto "This is the end". He didn't have any plan involving Kaguya's dimesion, which he doesn't know about to begin with...

maybe edo kages, madara, naruto and sasuke vs kaguya that would be super ultra fight
