Madara will return soon; Kaguya is probably irrelevant now, and currently this new Juubi "not under her control" is the villain.

About the Ten Tails, about Madara, and then, about Sasuke…I will continue to raise the tension without restraint, in every way I can! Please follow this story of a boy named Naruto a little while longer, I will greatly appreciate it.
