The light cleared away, Naruto waking to find himself on the ground. His body was falling apart. He looked up and saw Kaguya standing above him. His release of all chakra in the world and let it flow through him and Kaguya had failed. And as destroyed as his body was, Kaguya was pulling herself back together. The Infinite Tsukuyomi providing her with all she needed to heal herself.
Kurama was yelling in his mind, as damaged as he was. "Naruto! It is time! That one fallback you prayed wouldn't come! Do it!"
Naruto looked around and saw Hinata's zombie form falling apart as he released control of the Edo Tensei. He crawled towards her.
"What a resourceful young man." Back Zetsu said, walking up to him. "Tell me, Naruto Uzumaki, 'savior of the world,' where are you going?"
Naruto smirked as he grabbed onto Hinata just before she faded away. "If I'm lucky, wherever you're going so I can taunt you with your failure."
He activated the millions of pounds of C-4 buried under every elemental nation and activated every Hiraishin seal he could. He would not leave the world to be enslaved by Kaguya. So if this was the end, he would take it all down with him.
And suddenly the entire world was a flash of light. Even if it wouldn't take Kaguya down, it would destroy the tree and eventually Kaguya would die.
