Chapter 46 : The Uchiha Brotherhood (Part - 2)

Sasuke P.O.V

Itachi: You're certainly strong but you still lack the same eyes as me. So you couldn't kill your best friend eh? You'd still come before me with such a naive heart?

Sasuke: Well then, let's see you use that Mangekyo Sharingan of yours to kill me. Unless you find my strength too much to test your capacity on.

Itachi sighed softly and finally got off that damn chair.

Itachi: You sure sound confident. Mangekyo Sharingan. These eyes are very unique. From the first moment you awaken them, a slow descent into darkness begins. The more you use then, the more it takes its toll. 

Sasuke: What...are you talking about?

Itachi: The kaleidoscope will eventually lose it's light. 

Sasuke: You mean a loss of sight? So that's the price you pay for obtaining the power that can even control the Kyuubi. 

Itachi: I guess you read the tablets I told you about in the clan's secret meeting place. 

Sasuke: Who the hell is Madara?

Itachi: The first one to awaken the Mangekyo and the one who used the sacred tablet to summon Metsujin Akame from the other world. He was also the first man to tame the Kyuubi with his eyes. He's an immortal man, my accomplice and my mentor. He's also the only man to unravel the final secrets of the Mangekyo Sharingan. 

Sasuke: The final secrets of the Mangekyo Sharingan? It can do more than tame the Kyuubi?

Itachi: Indeed...it has a more use. One of utmost importance. The ones who take another Mangekyo Sharingan user's 'light' gains an eternal power. Eternal Mangekyo Sharingan! A light that never dies out! And...it is that light that I want. I want you to become my eternal light!

Wait...he meant me giving him my 'light' i.e my eyes? I watched in shock and silence as I saw the maniacal grin that crept onto Itachi's face. Is this the reason he kept me alive all this time? To reap my eyes? Did he not consider me a worthy foe...not even once?

Itachi: The current Madara is nothing but an empty shell of his past.  The only person who can surpass him and gain true immortality is me! And now, I am finally capable of obtaining a power greater than that of Uchiha Madara...and you will be the one to give it to me, Sasuke!

Why were we facing each other like this? Was it because we were the Uchihas? Was it because this was the bond that brothers of the Uchiha household were destined to have? The destiny to be each other's 'light' in a race to break the boundaries of power? Was that the reason my kind brother turned into the monster I see in front of me?

I quickly used the fireball jutsu to lure Itachi outdoors. As Akame would rightly call it...setting the stage for the finale. It's a pity that the Itachi I knew was so long gone...if even a vestige of the 'old' Itachi remained, he would have been proud of the ending I had in store.

Our fireballs clashed, each just as fiery and large as the other. It gave me a slight sense of pride. In the past, I couldn't match to Itachi irrespective of how much I trained and now...I was strong enough to break out of Itachi's Tsukiyomi...

My fireball was beginning to overpower Itachi's fireball. Of course. It was a matter of age and the practice I did. The great 'Itachi-sama' wouldn't have bothered with such basic level jutsus on his journey for greatness. Just when I thought my victory was nearly guaranteed, I saw Itachi's closed right eye begin to bleed... Wait...what?

Itachi: Amaterasu(Heavenly Illumination)!

I watched in shock as my fire was getting devoured by Itachi's black wisp like fire. My flames were completely eradicated by Itachi's flames. Before I knew it, Itachi began to create pinpointed attacks of those black flames. I brought out my second state cursed seal's wing to increase my speed at dodging but soon enough it was on fire. I gasped out loud as the black flame continued to devour my wing. Was this...Itachi's flame?

I used the Amaterasu flames as a cover and 'shed my skin' a.k.a used a replacement jutsu. Using this momentary advantage, I transformed myself completely into my second state of the cursed seal. Using the chakra boost from my transformation, I sent a volley of fire attacks at Itachi.

Sasuke: Katon : Gouryuuka no jutsu(Fire style : Fire dragon jutsu)!

I could see it. Itachi's right eye bled worse than before. Consecutive use of Amaterasu would cause a huge drain of chakra and his body would suffer heavy consequences as well. The plan was perfectly in motion. I needed to get Itachi to his lowest point...then I would show him the jutsu I have in store for him.

We were both exhausted. Ninjutsu, Genjutsu, Taijutsu, Bukijutsu, Kenjutsu...all of it led to this moment. We were both running out of chakra. Perhaps this was the lowest I could get Itachi to. If I wasted any more attacks, I wouldn't be able to execute that final move...the move I had developed just for Itachi's sake.

Itachi: Sharingan has the ability to see chakra. Your bluffs won't work on me. I can see that you are running out of chakra. The Orochimaru-like replacement technique that you used to dodge my Amaterasu...it must have devoured a considerable amount of your chakra. 

The sky rumbled and crackled. A sign. An omen of things to come... an omen of victory...for me! 

Sasuke: That's right...I did use up all of my chakra on the fire jutsus...but...do you really think I came unprepared for this battle? Just like the Amaterasu, this is going to be instantaneous...it is impossible to avoid it!    

I had shot all that fire jutsus in the sky to heat up the atmosphere to create an air current...to create thunder clouds. Instead of using my own chakra, I was going to tap into the the tremendous power that nature possesses and use it for my lightning jutsu. My jutsu is going to be something completely different. Itachi said he wanted to see power beyond current limits...and I...was going to show it to him.

Sasuke: Disappear alongside the thunder. Come forth, Kirin!

I watched as Itachi's eyes widened in shock. Even he cannot dodge something like this. Lightning comes down in milliseconds...it will be over before he even realizes it!

A huge explosion rocked the ground and the building got destroyed to pieces. Itachi's hideout...along with it's master were obliterated from the world.

It is over...

It is over...

It is finally over!

The euphoria of victory made me dizzy with happiness. In front of me...was the body of Itachi Uchiha. The one who immersed in the world of darkness...the one who taught me what true hatred tasted like...how powerful it truly is.

"Nee...Sasuke-san...do you really think the battle is over?"

My eyes widened in shock. She was here? She was truly here? But more importantly...what did she mean?

Wasn't the battle over?
