Disclaimer: I don't own Naruto or The 100

AN: Hello everyone! This is my first fanfiction so it's probably less then perfect but I'll try to give my best. I'm currently quite obsessed with The 100 and this idea has been on my mind for a while now. I'm aware that this chapter will seem like it is only a Naruto story but it is intended that way. The next first chapter is going to be focused entirely on The 100 and in the second chapter the two will merge. So please don't worry this IS a crossover.

I'm not sure of the pairing so far but it will most likely be Clexa as the main pairing, if you have other wishes you can obviously send them to me and I will think about it, the only thing I can say for sure is that this will NOT be a Harem story of any kind. A love triangle? Maybe, it depends on how many of you want it and between which characters but a Harem is out of question sorry.


Prologue

It happened during the last hours of the Fourth Shinobi World War.

Naruto feels exhausted, lying on the ground right beside Sasuke after their last battle. Every inch of his body hurts after hours of intense fighting with his former teammate and rival.

Their battle, as devastating as it was awe-inspiring had left it's mark, both on them and the surrounding area. Between the rubble the bodies of the two most powerful Shinobi in the Elemental Nations could be seen, each with one arm less than they had before their encounter.

While Naruto tries to move his body for what felt like the hundredth time, he could hear a groan beside himself. Finding enough power to at least turn his head, he looks to his right where he could see the unmistakable form of Sasuke.

'He looks just as bad as I feel, which isn't that surprising considering how our fight went' the blond muses. 'Not that the war or our clash with Madara and Kaguya before that helped...' the thought about the mad goddess causing him to slightly narrow his eyebrows while his rival stirs besides him.

'Kaguya...'

That the first seed of doubt in me was planted.

He can still remember the brutal, almost unstoppable force of nature that calls herself Kaguya Ōtsutsuki. It was almost ridiculous how powerful she was compared to them.

'Is.' he corrects himself, fully knowing that even with the combined strength of all that were still awake during the fight, the best they could do was seal her away.

'And even that took everything we had.'

He can still hear her words echo in his mind almost as if she's still standing in front of him, taunting him.

"You think you can change them? Change your friend, that abandoned you and your village just to seek revenge? Change the people, that shunned you, hurt you and ostracized you for something you didn't even know? Change the Shinobi,that bring war, death and destruction with their very existence?" she asks with an amused smile.

Doubt that maybe, just maybe, I was wrong.

"How very naive of you." the white haired goddess chuckles. "I have watched in my prison for over 2000 years.

2000 long years, seeing the cruel things humans do using MY Chakra!

2000 years of war, death, suffering and destruction brought by the people that claim it is only to protect their family and friends, without caring about the lives they destroy along the way. Even before my reign, all that humans were capable of was to bring misery! Destroying the world they inhabit just as much as they destroy each other!" she shouts, her voice getting angrier with every word.

"No." she says with finality. "Nothing you can possibly do will change them. In the end, they will betray your trust in them, they will take what little hope you have for them and crush it right in front of your eyes." The words, gently spoken leave her lips as she slowly approaches him, his body tensing up in anticipation of an attack. But her next actions surprises him.

That not everything was as black and white, as I used to believe.

She cups his cheeks, bows down a little bit and kisses his forehead, similar to what Tsunade did all those years back after their bet. So surprised by her action he freezes for a moment, not believing what just happened. After a few seconds she removes her lips from his forehead and looks in his eyes, still shocked he can't help but look right back into hers.

Unlike before, when she mistook Sasuke and him for her sons, there were no tears in her eyes, but a great sadness still. And with a sorrowful smile she speaks again.

"You really do remind me of my son. He had the same hopes for the humans, the same naive believes that they would change and start to understand each other. And in the end he was wrong. His own sons fought each other destroying his legacy of peace followed by generations of war and death, using the very gift he gave the people to form peace to kill and bring war."

That things weren't as easy as I thought them to be.

"I know you don't understand why I do this, and probably never will. I will end this madness before you have to face the realization that no matter what you do, nothing will change.

It saddens me to know that this is also the reason you will never let me do what is necessary to finally bring an endless peace to this world, but if you oppose me, I see no other way than to end you." were her last words before she backs away from him again, readying herself to continue the fight.

Before he can completely understand what just happened, before he can really contemplate her words, a portal opens behind her, Sasuke jumping out of it already forming handsigns for a Jutsu. Naruto snapping out of his stupor, jumps into action and helps the young Uchiha, shoving the past minutes into the back of his mind. Because no matter what Kaguya says, he knows she can't possibly be right... can she?

But I was still young and didn't knew any better.

"Are you still alive loser?" a voice interrupted his thoughts causing the young Sage to focus back on the Uchiha that lies beside him again.

"You should worry more about yourself bastard, you're in a way worse shape than I am."

comes the cocky reply of the blond.

"Hn. Keep telling yourself that if it helps." the raven haired boy grunted out, a smirk on his face that was still as insufferable as Naruto remembers it to be.

'At least the time with Orochimaru didn't change him that much, he's still an irritating ass, but I guess I can work with that' he couldn't hold the slight chuckle that escapes his lips at the thought, gaining him a raised eyebrow from his rival.

"Hey Sasuke. Think you've got enough of a beating to finally come to your senses, or should we go another round?." Naruto taunts his former teammate, fully knowing that even if he wanted, he couldn't move any more than the young Uchiha beside him.

"Tch, you're one to talk idiot, I hit you as hard as I can and you still wouldn't stop pestering me to come back to Konoha." letting out a sigh the raven haired Shinobi continues, "But I guess it wouldn't hurt to try it your way once."

The smile that lights up the blonds face was just as bright as his sun colored hair. Trying to annoy his rival, he puts on a smirk and asks him, "So you think I'm right? That my idea of bringing peace is better than yours?"

'Not that it was a good idea to begin with, I mean seriously? Being the super villain that all others unite against instead of fighting each other to bring peace?... And he calls me an idiot.'

"Hn. No you loser, all I'm saying is that your idea isn't as stupid as one would expect from you."

So I put my doubt away, to never come back again.

'I guess that the most I can get him to admit. But I'm sure that it is more than enough. If the bastard can put his hate aside for now, I'm sure a world without hate and bloodshed really is possible.' Sighing he looks back to the sky, still not able to move he waits until he recovers or for someone to come and see what happened now that the fight is over.

'What do you think Kurama?'

For the first time since his battle with Sasuke, his tenant speaks, wanting to leave his host to his own thoughts to process all that happened until now.

'I don't know Naruto. While Kaguya clearly was mad, she does have a point. In all my years, roaming the Elemental Nations I have met many humans, and as much as you won't like to hear it, you and people like you are the exception. There is more hate in this world of Shinobis that even I can hold.' the words of the Tailed Beast ring loud through his mind, making him narrow his eyebrows in irritation.

'Is is possible? Maybe. Is it likely to happen? Not really. I will stand beside you partner, no matter what happens, but you should prepare for the possibility of failure.' the giant fox says before cutting their connection and pulling back into the blonds mind.

And looked forward to a peaceful future, I would help create.

'Tch, watch me old fuzz butt. I will rid this world of all its hate and anger just like I did with you. And then you better apologies for ever doubting me' the blond Sage thinks with conviction, already envisioning a world where he and all his friend live happy and peaceful lives. A world without bloodshed, where everybody works together for a better future. A world void of war and misery.

'And you watch too Kaguya. Watch as I show you just how wrong you are. I will bring peace to this world, even if you think it to be impossible. And if it's the last thing I do!'

Not believing his thoughts to actually reach her, he still holds them. Maybe not to convince her, but to make sure he will never forget them.

At the edge of his peripheral vision he can see to figures approach, male and female respectively.

"Seems like Kakashi-sensei and Sakura-chan are coming to pick us up bastard. Heh, I'm pretty sure Sakura is gonna rip you a new one for the stunt you pulled earlier." the blond laughs.

"Hn" was all he got in response. 'As eloquent as always it seems'

"Naruto! Sasuke-kun!" he could hear his female teammate shout in relief as they approach the two boys lying on the ground, still alive. I didn't take long for her face to turn into one of horror though, as she could finally see the condition they were in.

Build together with my friends and comrades.

"Don't worry Sakura-chan, the bastard and I are alright, just a little banged up." the young Sage assures her with a smile.

"Are you kidding me! You both lost an arm! How is that just a little banged up?!" she berates him , but he can see the slight wetness of her eyes and the worry in them.

"So I guess it's done?" the members of Team 7 could her their Sensei ask, trying to distract his female student before she can start the rant that was sure to follow.

Naruto and Sasuke look at each other again as if trying to confirm something. After a couple of seconds they nod at each other and turn to their teacher again.

"Yeah it is. It's finally over" the reply came in unison. They could see Kakashis eye turn into his usual eye-smile that indicates him being happy.

"That's great to hear, then let's bring you two somewhere you can be treated, wouldn't want my cute little students to bleed out like this now." came the amused voice of the silver haired Jonin before he bends down picking up Naruto, while Sakura picks up Sasuke.

So while the two young Shinobi are being carried away by their teammate and teacher, the last thought Naruto has before he finally succumbs to exhaustion is,

'We can bring peace to this world,... I'm sure of it.'
