Disclaimer: I do not own Naruto nor anything I crossover this story with. I make no profits from this story whatsoever. The first few chapters is just Naruto's general childhood. I've written my fair share of Fanfiction for Naruto, as in this isn't my first fanfiction account. And it's not my best… Yet. Nevertheless, I normally jump straight into the action. Skip the childhood because I can't really figure out how to make it entertaining. So I'm trying something new. I hope you like it.
The world is a vile place. It has been since humanity first laid its greedy, corrupt hands on the world. I have lived for a long, long time. Longer than the Elemental Nations have been in effect. Longer than chakra has existed. My name is Kaguya Otsutsuki. I was once a princess, long ago. I witnessed the war of humans tear the Earth apart. Constantly, never halting. Endless war after endless war. Unneeded death after unneeded death. I grew increasingly tired of watching humanity slaughter itself. I grew tired of the corruption and the greed. I grew tired of the Earth as a whole.
"Come here, little Naruto. Never wander too far from Kaa-San. There are many bad people in this world, and those bad people want to hurt you."
So I took the needed measures to stop the wars. I ate the forbidden fruit from the tree, Shinju. It gave me the means to decimate the damnable humans that spite their own kind, just so that they can get a one up on one another. It granted me chakra. And I ended war! I brought about an era of peace, and I was worshipped as a goddess! But… Humanity does not like things that it cannot understand. Humanity did not like me. It did not like my powers. So I became a demon to them. I became a monster. Me! She who had brought them peace in their damnable wars! Damn them!
"Kaa-San, where is Zetsu?"
"Zetsu is busy carrying out errands for Kaa-San. If you want to spend time with one, you'll have to settle for White Zetsu."
"But I don't like white Zetsu! He's ignorant! He just treats me like a little baby and it makes me want to slaughter him!"
Nevertheless… I continued on with my life in their now worthless world. I continued my existence, so that peace would continue. And I mothered two children. Hagoromo and Hamura Otsutsuki. They were both my greatest blessing… And my greatest curse! I loved them. Truly, I did… But they took what was not theirs! They took power from me, they took chakra… No other should ever had wielded that power! There must be imbalance for their to be peace! And as long as I was the only one there was peace! But they took power nevertheless…
"Do not squander your time, Naruto. We do not have eternity together. Not right now as it is. Practice. Wield the weapon as though you mean it. As though it were part of yourself… Now strike my child!"
"Hai, Kaa-Chan!"
I loved them… But by God at the same time I despised them. I could not let any ruin the peace that I had attained. I simply could not allow it to happen. So I sought out the Shinju and fused with it. We became a single entity, known as the Juubi… A Procreator to the Shinobi world. I ran rampant through the world. I was going to make sure that I stopped any chance of war ever returning to Earth. And then came my sons. Damn them… Damn them to the deepest pits of Hades! I damn them! They sealed me away! Me! Their mother! Creator of peace! They sealed me away and split the Juubi into nine separate entities. Only their reunion could allow me to be unsealed from my damnable prison. But…
"Kaa-San, am I evil?"
"No, Naruto… You are not evil. The world around you is evil. And to counteract that, I have made sure that you can survive in this evil world when I can no longer protect you. When I can only contact you."
"Is that why there are bad people up here?"
"In your mind? Technically they are not just in your mind. But sealed with you. And yes, that is why they are there. To help you fight through this evil world. Do not listen to everything they tell you though. Else you may end up in the exact same type of hell that they remain in."
"Yes, mother."
… But not all was lost. I had once planned to cast the world into an Infinite Tsukuyomi to prevent any farther war. To cast infinite peace. I succeeded with a few, and attached them to the Shinju. They eventually turned into the beings that would become known as 'White Zetsu'. And when I was sealed, my will manifested into the creature that would become known as 'Black Zetsu'. Black Zetsu used one of the white counterparts and what the humans had dubbed as 'Kinjutsu' to give me a physical manifestation.
"Kaa-san, what's a Me-cha-te?"
"A Machete?"
"Yeah! I think that's what it is!"
"It's a bladed weapon. Similar to a sword. That's the best way to describe it. Why do you need to know, my little one?"
"The men in my head tell me weapons that are useful. And sometimes in certain situations. But some of them don't talk. They only sit there. Breathing I guess. But I guess the other guys know what they're thinking, because they talk for them sometimes. One of them said that another used a ma-ch-ete."
"I see."
"Do I listen to them now?"
"You listen to them when you believe that it is important and beneficial to yourself my sweet little one. And only then."
"As you wish, Kaa-San."
I grew tired of Zetsu's choices to carry out my Infinite Tsukuyomi plan. I grew tired of watching him manipulate the Uchiha and Senju clan in an attempt to reawaken the Rinnegan. And I placed no faith in his choices. I placed no faith in 'Madara' and 'Obito' Uchiha. Because they were weak! Every generation after my children grew weaker and weaker. The Uchiha that Zetsu recruited were no match for the wide scale pandemic that my plan required. And so, I devised a plan to patch Zetsu's ignorant mishap.
"Kaa-Chan…?"
"I'm fine, Naruto-Kun. I'm… Mommy's sick. Very very sick."
"What do I need to do Kaa-San?"
"You need to start harnessing your powers… Before you get sent away for your training."
"Kaa-San… As you wish!"
I conceived another child. This time by deceit. I posed as a human's wife. His name was Minato Namikaze. I held no affection for that human whatsoever. I simply needed a child. So I conceived one. My little Naruto. Through me, my child received my powers, my chakra, and the chakra of the Shinju. But I was okay with that factor. I allowed it. Because I loved my son more than anything else I've ever loved. Because I wanted him to have that power.
"Zetsu, the time is nearing. This manifestation you've given me… Is fading. And I will not return until I've been unsealed… You have your instructions on what I wish you to do with my little Naruto-Kun. Fail me, and the wrath of God will fall down upon your head Zetsu!"
"I understand."
He would be the one to carry out my plan. Naruto would unseal me. And together we would carry out whatever plan of action was needed for the world. Rather that were to be casting my Infinite Tsukuyomi, or decimating the world's shinobi forces. But… I needed Naruto to be prepared for the evil world that he was to face. So I scoured the pits of hell using what energy I had left to sustain my body. I found the greatest minds that had killed. Minds that had lived before me.
Beings that I sealed within my son. 'Jason Voorhees', 'Michael Myers', 'Freddy Krueger', 'Ghostface'. Their likes. Serial killers, they were once called. Ominous and vengeful spirits. Some with supernatural abilities that Naruto himself could learn to harness. Of course, they could only contact Naruto when he allowed it. And even then, I had far greater say in the matter than my little Naruto did.
And so, I raised my son. As my physical manifestation faded, I raised Naruto to harness my powers. I raised him to harness my chakra. I raised him to use his Byakugan and his Rinnegan. And the monsters in his head taught him how to harness their powers. Their intelligence. Their strength. But… his childhood doesn't end there. No… By the time my physical manifestation had reached its end, Naruto was merely at the tender age of seven.
"Naruto…"
"What is it, Kaa-san!? What's wrong!?"
"Naruto… This form has met its end. I am leaving this plane of existence to rejoin the rest of myself in my prison. Remember all that I've taught you. Remember that I love you. And remember your existence. Remember that it is only through you, the Child of Prophecy, that I can return."
"I will Kaa-San! But-"
"No buts. Listen to Kaa-San carefully now… Zetsu is on his way to retrieve you. You will leave with him, and he will take you to your teachers to train you. You will learn from them as you've learned from me. You will hone your skills. And when you're ready, you will begin your journey to unsealing me. Because, as of this moment… You have not yet begun your true journey. I love you, my little Naruto."
"I love you too… Kaa-Chan…"
I no longer have a physical manifestation in the world. It has passed from the Earth. But my will there is strong. I have a following of shinobi carrying out my will, and they don't even realize it. Ignorant… Ignorant… Humans. No longer do their petty squables matter. From here on out… My little Naruto will finish what I started. He will carry out the mission he was birthed to do. He will use the powers I gifted him to unseal me. And then… We will rid the world of the pestilence it has brought upon itself. We rid the world of the war that it kills itself with.
I leave my will… My chakra… My powers… Everything… To my one true son.
I leave everything to my Naruto Otsutsuki.
