'Awaken.'
He jerked his head, as his eyes blinked open slowly, feeling a cool sensation all over his body. The first thing he noticed when he opened his eyes was that everything was green. No…he realized everything was green from where he was. He was inside a glass tank filled with some green liquid, wearing a white full body suit with multiple bindings to restrain his limbs and a mask of some sort that he soon realized was providing him with air. He glanced around the room and saw it was empty, with only two doors beside each other at the other end.
There were no people, no tables, no chairs, only a metallic floor, walls, and ceiling. The only things in this room were two tanks. One of which held him, while the other held a girl with long flowing green hair wearing the same full body suit as him. And she was looking straight at him with intense yellow eyes that seemed to bore straight into his soul.
'Wh-where am I?' He thought to himself.
The last thing he had remembered was personally fighting Uchiha Madara with his friends. After that, there was a flash of light, and things began getting blurry.
'You're in a Britannian research facility in the Militarized Zone of India. You fell from an opening in the sky and landed right at their feet, where you proceeded to kill more than half the scientists and researchers at this facility using some unknown power, before they finally managed to subdue you with their Knightmares.' A female voice whispered in his mind.
'Was that her? Is she speaking into my mind?' Regardless of how she was doing it, her words were bringing back memories.
He remembered…
Uchiha Madara attempting to capture the remaining Biju(Tailed Beasts) to revive the Juubi(Ten-Tails), preparing to subjugate the world in Infinite Tsukuyomi as he captured Naruto and Killer B but Naruto was saved by Obito at the last second. He knew that Madara would force him to use his stolen Rinnegan to revive him and when that happened he'd be able to seal the Juubi inside of him. He knew that Madara had Zetsu looking for the other Rinnegan he hid away and he would use it to bind the other Biju and seal them back into the Demonic Statue of the Outer Path. He couldn't let that happen so he did the only he could do: deny Madara the chance to revive the Juubi.
Obito Uchiha creating a giant Kamui portal to swallow up everything to prevent Madara from capturing the Kyuubi inside of Naruto. He extracted Shukaku and Gyuki and sealed their chakra inside Naruto with the chakra of the other Biju to prevent Madara from summoning and sealing the Juubi inside his body to gain its power.
Everyone hanging on for their lives as they struggled to not be pulled into the dimensional portal.
Naruto being pulled forward and creating a massively large Odama Rasengan to collide with the portal, sealing it up to stop Madara from chasing after him.
He knew he wouldn't be coming back…
He had no regrets though…
He managed to stop Madara's plans of robbing the world of free will
Perhaps the world he left will start over with the very few survivors learning how to make peace like his family had strived to create for centuries.
He knew he wouldn't be Hokage now but he supposed Sasuke-teme would make a decent one, making sure that history never repeated itself.
"Naruto-kun!"
He remembered hearing Hinata's voice crying out to him as he vanished, smiling at how ironic it was that he had spent his life never being noticed and he never noticed her until it was too late. If he could turn back the clock of time he might try giving her a chance.
