After the war with Madara, Uzumaki Naruto became the Rokudaime Hokage but it was not the cheerful occasion the he hoped for. During the war Konoha had lost more than half of its population, two-thirds was the shinobi and two-fifths civilians. None of the other hidden villages fare any better either. Naruto was 22 when he became the Hokage, and when he fully merged with Kyuubi's chakra, because of this he became what Orochimaru always wanted to be, an immortal. Time went by and the rest of Naruto's precious people die, he retired at age 57 and is one of Konoha's elders even though he still looks like he's in his early 20s. Millenniums passed by and Naruto had seen the village rising from their ashes into a Golden Age and had seen their fall to modern technology. Soon the shinobi arts were forgotten, but Naruto just kept on training in everything that he did not learn before, and adding to the list of jutsu as he gains more knowledge. He is the only true shinobi alive, not like those ninjas you see on television, and the thing he regretted the most was not being able to make much of a difference for his people when they were alive. In modern time right now Naruto's companies are the biggest ones in the world, but what everyone doesn't know is that he is still working on a time seal that will change so many things even if it was selfish of him to want these changes. Another century past and the seal was finally finished, the Kyuubi, since he decided to keep him in his conscious, had explained to him that he'll lose his immortality if he goes back, but he'll still have all his skills since they're sending the whole body back in time.
'I'm coming back guys, this time I will make a difference.'
'I'll make sure you arrive safely Kit.'
'Thanks Kyuubi.'
'Here we go kit…'
'All or nothing!' they both said and a black hole opened up and sucked Naruto in.
