Disclaimer and Background to story:

Thank you all for giving my humble story a chance I do not own Naruto in any way, shape or form. All rights go respectively to Kishi-sensei. As for the background to our story..this is set in the same exact Narutoverse as what is canon up to the great ninja war with Kaguya. The only difference is that, like Naruto, Sakura has a beast inside of her that only Kakashi and Tsunade know of. The beast is called a Kemona. The Kemona, which I won't give too much away, is not like the tailed beast Naruto has. It is much, much worse and far more insidious. It is female in nature due to the fact it feeds off the personality and attributes of its host. This is solely a SasuSaku fanfiction and contains also some Naruhina at a few parts. Please enjoy and be aware that there may be some adult sexual themes in later chapters!

Chapter 1

Sasuke..Sasuke just didn't seem to care. My limp and useless form dangling above a chasm of lava and he doesn't even give me a passing glance. Not a look of worry. Not even a look at all. Even some eye contact would have saved me at this point. But no. Sasuke did not look at me. He did not care for my well-being, or Kakashi-sensei's for that matter. We were only his burdens now, no longer bonded to him. And Naruto only being carried off by his hawk to safety so he can be murdered in cold blood later on. I hate him..I hate him so much I feel like crying every time I look at him. I hate the way my heart clenches in my chest at the sight of him. Or how my mouth goes dry with cotton when he speaks directly to me. I hate him for saying my name like that. Like he still cares. He doesn't deserve to say my name..he doesn't deserve my unwavering and unequivocal love for him.

Kakashi lifts us up to flat ground and I sigh only to cover up the wail that is my cry from pure emotional pain. I have felt physical pain unimaginable to any normal shinobi, but this..this was the type of pain that can't be explained. Like someone plunged their hand into your chest arm deep in order to rip out your still-beating heart. All with a smile. Kakashi is aware of this pain I have. But he disregards it. He gives me my space by looking away, toward Sasuke and Naruto flying onward.

Kaguya's power is too great. It is just too much, too maleficent. I watch in agony as sasuke and Naruto are beaten to a pulp. When suddenly, kaguya pulls a chakra sword out of thin air. The sword was beautiful, in a repulsive way. Its light pinkish color was incredible and its brightness blinding. I watched in amazed horror as the sword slowly moved through the air and into Sasuke's stomach.

A ringing fell on my ears. My hands grew numb. My face hot with invisible flames. I couldn't breathe, I couldn't think. All I wanted was his safety. I wanted him safe. I wanted him unharmed. How dare she put even a scratch on him. And a thick black cloak clouded my eyes. As if someone had poured a dark food coloring into my corneas. And the last thing I saw was Sasuke's eyes wide with sheer shock baring holes into me.

Naruto

Our fight against Kaguya was brutal. But not near as brutal as Sasuke's treatment of the others. Although he comes off as he didn't give two shits about them falling to their death, I knew better. I wasn't stupid. I knew he saw kakashi willing and able to save himself and sakura before kakashi knew himself. Sasuke cared. And there was not shit he could do to make me think otherwise.

Kaguya's monster strength was pissing me off, Sasuke too. As we grew tired, he got sloppy and got just a little too close. Before I could even try to help him, her massive chakra sword cut right into the pit of his stomach, and out the other side.

"SASUKE!" I screamed so loud I popped a blood vessel in my left eye. Before I could leap to action, or even say his name again, I noticed Sakura.

But it wasn't Sakura, not anymore.

It was something much more fucking terrifying.

Standing where Sakura was once sitting, was her silhouette bathed in dark blues and whites of an incredible cloud of chakra. Slowly, her head began to look up towards us. Her face was the same, her body and seal still exactly the same as before. But her hair was at least ten inches longer and blowing wildly around her face with the burst of chakra. And her eyes..her green emerald eyes were completely blue. A shining terrifying blue that bore into me. Her face had no expression, and her body language was completely relaxed. And then she was gone. Her speed was so fucking crazy I almost fell over trying to find her.

"Kakashi-sensei! Where'd she go?!"

"Naruto! Get out of there now!" Kakashi's blood-curdling scream didn't reach me in time. He obviously knew what the hell was happening to sakura, and that is was nothing good. When my eyes finally found her, she was standing between sasuke and kaguya. Sasuke had fell to his knees after kaguya had pulled her chakra blade from him.

"sakura stop! She'll stab you too!"

"Sakura..? What..what is this?' I could hear Sasuke stammer at her trying too to figure out just what the hell had happened to her.

" I have no use for a god that does not know her place. Be gone." Sakura, or what looked like sakura, said in a horrible harmonic voice somewhere between sakura's and something else. Something evil.

And with that, she simply drew back her hand and slapped the Goddess into a nearby mountain with a speed and velocity that left us all falling backwards.

Sasuke

"I have no use for a god that does not know her place. Be gone."

What..what the hell is this? What is she?! This can't be Sakura. There is no way she gained such god-like strength in only a few short years. No..she couldn't have gained such strength in a 100 years. None of us could. This is impossible. What the hell is going on?!

Sakura turned to face me, just the side of her face showing with one bright flaming blue eye glaring at me, a smile playing at her lips.

"So you're the great Sasuke Uchiha. I have heard much about you."

She turned completely this time, slowly walking toward me still holding that malicious grin.

"Looks as if my host wants you alive more than she wants her freedom. Pity. Though I do see why, you are very easy on the eyes." She smirked with a wink.

She put her hand on her hip and flung her hair out of her face.

"That truly is such a pity, because she is going to lose her freedom..as well as you. You see I need chakra to survive. I need it to fully take over this vessel. Without an extra boost, she will unfortunately take over once again. So if you could kindly comply.." she started at me again. I can't move, I can hardly breathe. This thing can easily kill me, even in my best state she could take me easily. No..no I cant go out like this. I cant let this thing kill me and sakura as well. I just cant.

Suddenly, Kakashi's body is flung infront of my slumped form between me and this thing using sakura's body. He is in a horrible condition, he can barely stand.

"Kemona, you are not welcome here. Go back where you belong." Kakashi spit out, between raspy and harsh breaths.

Kemona bursted out a bellowing laugh that sounded exactly like sakura's. But it wasn't. It lacked her charm, and her pureness.

"Back where I belong?! You mean in the back of the mind of this stupid girl? Ha! I am a god. A mother to shinobi. A goddess of the shinobi world, why would I live my days trapped in a love-struck teen?"

"you are no god, Kemona. You're a parasite. You take the likeness of your host, you don't even have a personality of your own. Everything, down to your resentment towards Sasuke, spawns from Sakura."

"That's where you're wrong my dear. I only require chakra, the boy was harmed and useless. I was simply taking advantage of his current state."

"That's bullshit and you know it."

Kemona's blue flare eyes glared at kakashi for only a moment before composing herself.

"I am much more than what meets the eye, young man. Here..let me show you."

An incredible amount of chakra visibly pulsated around sakura's body as she lifted into the air. Her arm beckoned something unseen to come towards her. After a second, kaguya's destroyed body was lifted from the crater and headed towards sakura.

"I WILL ABSORD THOSE WHO ARE USELESS AND USE THOSE THAT ARE OF VALUE ONLY AT MY COMMAND. THE WORLD IS MINE!"

As she spoke, kaguya's body began dissipating into the chakra cloud, and with it gave sakura's eyes a horrific black glow. The bluish tint of powerful chakra around her turned into a thick black substance. Infecting her eyes and clouded around her.

"While I have you all here, I think I will start with your home dimension."

With a gesture of her hand, a portal opened. Inside we could all see the shinobi fighting for their lives and healing the wounded. They could see us too.

With another small gesture, Kemona ushered the chakra of all the nin to be absorbed into her. We could see them all suddenly regress to sickly looking older versions of themselves. She had to be stopped. At this rate she'll kill us all, she's just as bad as kaguya if not worse. I can't let this happen, not to sakura. Not to everyone. I will do whatever I have to.

Kakashi

"I promised Sakura's father I would keep her beast under wraps. I made lady Tsunade swear under oath never to speak of it to sakura as she indirectly tried to lift her of this curse."

"Kakashi sensei..what exactly is she?" Naruto said

"Every 9th child of the 9th child of the Haruno clan produces a Kemono. The male Kemonos prefer to be called as such, the female prefer Kemona in order to differentiate and feel more human. These parasites are born within a vessel, feeding off its personality and chakra hoping one day to release itself. There are horrific and powerful creatures. Only one other actually released itself as far as we all know. Kemono the first, as he is called, claimed the life of his host Sharuma Haruno in ancient times. The sheer power made the plates of the Earth move, separating continents and creating the countries we know today. The only way he was defeated was by an act of sheer impulse. Something so sudden and incredible, that the beast reverted to its hibernation for a split second so the host could be killed. Which ultimately killed the inner beast along with it. Kemono the first was slain when Sharuma's eldest son confessed that he hated him. That he hated his father more than he had hated anyone. He said this with such a greatly fabricated honesty and false hatred that the beast and Sharuma both retracted in pure shock. Sharuma's son then killed him with a kunai to the heart. But not before he told his father how much he truly loved him."

"So that..that means.." Naruto stared up at Sakura's form in disbelief. His face mortified. Sasuke hid his eyes, intently listening to my words but making an effort to hide his true feelings and the look of pain on his face that probably mirrored Naruto's.

We had to come up with a plan. It was our only hope. But if we do what I think we should do, it'll kill sakura in the process. And I just don't think I could live with myself if I went along with it.

In a blink of an eye, sasuke was gone. With the hole still in his stomach he couldn't have gone too far. And I had a horrific idea of exactly what he was about to do.

Sword unsheathed, sasuke flung himself towards the floating monster that took over sakura.

"SASUKE NO!" Naruto screamed

"Sasuke wait!" I don't think I could bear to watch the man she loves more than anything on this Earth kill her. I couldn't watch this pure and incredible woman be slain by the hand of the man she adored.
