Pain. Every cell in my body feels like it's being lit on fire while simultaneously destroyed and rebuilt. Sadly enough it's only the 2nd worst thing I've felt. What's the worse thing I've felt you ask? Having my village destroyed, having every person I care for, and the last remaining one alive sacrifice himself. Once again sadly enough that was only moments ago. The pain lessens allowing me to think clearly - and one word burns itself through my brain Sasuke. I'll fix everything - my precious student Naruto with his recently found Fuinjutsu prowess had managed to send me back in time at the cost of his life. I refuse to fail! I won't let anyone die. I won't fail like the other times! The pain from my body being shrunk back and modified to when I was younger stops and I hear a sucking sound as I feel my body be pulled into something then a thump as my body is deposited on a soft bed. As I open my eyes they dart towards the calendar and my heart starts to beat faster seeing the date. 29 years. I've been sent back 29 years! It worked! My head falls back onto my pillow as tears begin to fall from my eyes and I let out a small laugh. The Ex-Hokage who's 50 years old is now stuck in his 21-year-old post-Anbu body. It worked even better then they thought! They thought they would only get him to be 30! Attempting to stand up I immediately groan feeling the extremely weak (for me) chakra and the contracting muscles. Slowly running through hand seals that I had only learned about two decades earlier right before the war. I tap the back of my neck once and I feel my chakra grow to the size it's supposed to be. Another hand sign and a sizzling sound as the Gravity seal on me disappears. My shoulders start to shake from the suppressed happiness - when I found out the first time about the Chakra seal I was so angry and when I fucked up on the gravity seal the day prior to finding out I knew I was screwed. It took me over a decade previously to get rid of them and by then I was permanently weakened. But now? I just might have the strength to change things. As I flare my chakra knowing the seals around my apartment will make sure none of it leaks out I feel the searing pain in my two eyes that blind me as they start to mutate my eyes - removing the blood seal that's placed on all Hatakes at birth stopping the Sharingan from forming. Rubbing my face as I stand up I quickly shower and get dressed then put my face mask on. Looking at my calendar I begin to form a plan. I have about a year until I'm back on active duty since I had just left ANBU the day before. With my routine 1 year recovery period I should be able to match the speed and strength that I had during the Fourth War and I should be able to get my body used to all my Jutsu again. Groaning slightly as I think about having to make my body relearn how to use my Purple Lightning with a Snake and then a Rat Seal a Resistance Seal is placed on my two ankles and my two wrists. Grunting slightly from the extra weight added onto my I flex my muscles a few times before hopping out of my apartment and towards the nearest training ground. Ready to condense over 4 years of training into one while improving friendships, making people think I'm mentally stable, and making sure people don't think it's strange that the previous A-Rank Commander of the ANBU Black Ops is now an S-Rank Jounin with two Sharingans that he can turn off at will, created a new Lightning Style that was eventually classified as a self-made Kekkei Genkai, and over 6x the chakra capacity he had the day before. Yes, it's indeed good to be Kakashi Hatake.
AN: Bit of a rushed prologue - I don't like writing in the first person but I feel it's prudent to write the prologue in the first person. Rest will be from a Third Person POV centered around Kakashi and his actions. Like most Animes, Mangas, and anything else written on the internet that isn't Gamer fics. Which this won't nor will never be a Gamer fic. Ex-Hokage Kakashi with Double Sharingan all 5 natural release, yin, yang, and with his improved chakra size from War Arc and afterward is OP enough thank you very much.
So a bit about this fic. This won't be a 'Kakashi uses Taijutsu for a while then Chidori a bastard to death.' Kakashi is a Ninjutsu specialist that has a best friend that is a Master in Taijutsu. If Kakashi uses Taijutsu against you - you're dead. Why would Kakashi waste Chakra on Chidori when he knows thousands of Jutsus that use less chakra and can kill you just the same? Why the fuck would he even use the Sharingan on you when compared to him you're fodder? It makes no sense. As you'll see as he faces stronger and stronger opponents that I won't nerf him. It's heavily believed Kakashi during the Pein Arc could have defeated Pein if he had the knowledge of what Pein did. So why the fuck would I have Kakashi lose to Pein if he could do it then? This Kakashi after his Training Arc would be able to be Pein-Arc Kakashi blindfolded, one hand tied behind his back and hopping on one leg.
This fic should show the real Kakashi Hatake of the Sharingan, the man feared throughout the Elemental Nations, the man truly worthy of being Hokage, and not that pathetic trash that loses to everyone or always passes out after a battle. Will there be people he actually has to try against? Yes! I'm not going to be like 'S-Rank opponent? Bah! One punch dead!' those S-Rank and above threats like Zabuza, Itachi, Kisame, Nagato, Konan, Obito, Madara, Kakuzu, and Sasori are indeed threats. But it doesn't mean Kakashi is going to have to pop out a Mangekyou Sharingan Purple Lightning Armor with a Susanoo to deal with Sasori. Would he have to do that against Madara? Fuck yes. Would he have to do that against Zabuza? No. So if you expect Kakashi to be constantly beaten down by those who old he managed to beat when this Kakashi has over 2 decades more experience, over 8x more chakra, better chakra control, stronger ninjutsu, is faster, stronger, and has access to forbidden Jutsu from his tenure as Hokage? Then this story isn't for you.
At the start, not much will be changed. Until Team 7 is formed Kakashi is going to take it to chill and slowly grow stronger, have his body get used to his Jutsu, relearn Purple Lightning, the eight gates, and have people grow bonds with him. However, a few things will be changed, for example after the year is over he'll start taking missions again. This will change things, missions that used to be tough in the 3.5 years period before Naruto started will now be easy. Allies that died will survive, enemies that survived will die, and most of all this will reinstate Kakashi Hatake as the Copycat Ninja. A ninja to be feared. It didn't make sense to me that a Ninja from another country knew essentially everything about Kakashi yet his own students from his own Village didn't know anything about him.
That being said the next chapter will start off 4 years later and will probably include a few Missions, him failing a team for not having teamwork, him being late, Kakashi reading smut, people yelling at people for reading smut while being late, and then finally the Mizuki incident. I might add the Genin assignment scene but who knows! Anyways that's what you can expect for the first official chapter!
(AN is the same size as the actual prologue btw.)
