Reborn in Naruto As Madara's Grandson

"Da… Da… Danzo! It's you. How could it be you? How are you still alive?" Izuna questions in frenzy.

Izuna recalls his memories of when he killed Danzo.

'I sealed him inside the Shinigami's stomach and I destroyed his body. How he is still alive? I am sure he even used his last Izanagi in the fight.'

Izuna calms down his emotions and scrutinize Danzo's body with his Mangekyo Sharingan. He activates his "Eye of Insight" and checks the changes in Danzo's body.

Throb… Throb…

The strange Fuinjutsu seal located in Danzo's chest is pumping out an enormous amount of chakra in his body. Izuna can see the 'Nature energy' rapidly getting converted into chakra.

'Is it because of this seal? Is this the reason Danzo is still alive? No, there seems to be more to it.'

The Sin seal on his hand heats up. The Grimoire pops out from its separate space and shows its hostility to the seal.

Izuna frowns from the strange reaction of 'Sin Seal'

"I have an iota of the idea, who did it? But to be on the safe side, I will kill Danzo again and will investigate this matter later."

Danzo's body regenerates and joins again.

Haha…

"Surprised? Aren't you? Seeing me alive and stronger than ever. Huh!

You killed me and sealed my soul inside the Reaper. I suffered inside that dark place for who knows how much time? My soul was suffering from endless pain and agony.

There wasn't a single moment when I wasn't tormented. In that darkness, a hand stretched out to me; the hand of a demon. I sold my soul to the demon and made a contract with him.

He gave me this new body and this power. I am stronger than ever. Even First Hokage Hashirama Senju isn't a match for me now. You are nothing but a measly worm whom I will kill easily with a snap of my finger.

I am immortal at this point. As long as my soul is fine, I won't die no matter how many times you kill this body."

Haha…

Danzo laughs maniacally and makes some hand signs,

"Fuinjutsu: Devouring Demon Chains"

He slams his hands on the ground and various dark black chains erupt from the ground from a purple-colored portal and chase Izuna.

Clank… clank…

Izuna deflects the chain, but they continue to chase after him like a homing missile.

Tch…

'These chains are so annoying. Every time I contact them; they suck my chakra and vitality.'

Izuna clicks his tongue and looks at the chains in annoyance.

'Let me try to freeze these chains.'

He jumps back and makes some hand signs.

"Ice Release: Snow Dragon Blizzard"

Izuna launches a giant dragon of ice towards the chains. The dragon attacks the chains and freezes them.

Danzo clasps his hand and infuses more chakra.

Rattle… Rattle…

The chains rattle and break free from the constraints of ice.

'Looks like Ice will work... but I have to use a stronger jutsu. Let me put that new Kekkai Tota to test.'

Izuna stops in his chase and confronts the chains. He claps his hands and infuses Ice Release and Fire Release chakra in his left and right hand.

"Artic Release: Freezing flames of Nothingness"

He releases large amounts of blue flames from his hands.

Sizzle… sizzle… Shoom…

The flames immediately cover the chains. The chains burn with blue flames for a while before freezing right in front of Izuna's face.

'Whew… it worked.'

Snap…

Izuna snapped his finger.

Crack… crack…

The chains trembled before shattering into countless pieces of Ice flakes. The chains turned into nothingness and it leaves not even a fragment of them behind.

The snowflakes cover the ground and the temperature drops below the freezing point.

'This jutsu is quite potent, but I am still not proficient in its uses. I want to use only one hand to manipulate all the Nature Transformations in the jutsu.

Well, that is quite difficult for current me. The complexity involved is way behind my reach, at least for now.'

Danzo's jutsu shatters and the Fuinjutsu seal formula breaks. His eyes widen and a hint of surprise appears on his face.

"This… this jutsu! What kind of jutsu did you use? How are you able to use such a powerful Ice Release technique?

As far as I know, you shouldn't be able to use any Kekkai Genkai except your Sharingan and Swift Release? How… how can you use so many nature transformations?"

Danzo questions him in a frenzy.

"Yes… this will do. Once I kill you, I will ask Orochimaru to study your body. All of your secrets will be mine. Haha…

Besides, my only task is to kill you, and I will be free from my restraints. The Demon only wants your soul, he has no use for your body."

Danzo chuckles in madness.

----------------

Somewhere in Land of Sound,

Inside an underground experiment facility,

There are multiple humans sealed inside many giant experiment tubes filled with nutritional liquid.

Orochimaru walks in front of one of the tube and presses some buttons. It drains the nutritional liquid from the tubes and the tube opens.

A white snake grabs the man by the waist and lay him on a table.

Hmm…

'This test subject is in optimal condition. Now, let's start the experiment.'

Orochimaru ponders to himself. He injects many strange serums inside the man's body.

The test subject's body trembles for a while before it explodes into a mess of flesh and blood.

Orochimaru wipes the blood from his face. A wide grin appears on his face.

Kuku…

"Hiruko, you fool. Did you think that by modifying the crucial step into your experiment log, you will be able to fool me? I have succeeded, I have finally found a method to gain immortality."

Orochimaru looks at the puddle of flesh and blood.

"Looks like I need a potent body to sustain my chakra and life force."

Image of Izuna appears in Orochimaru's mind.

"No, he is too powerful. I can't take the risk."

Then the image of Itachi appears in Orochimaru's mind.

"He is quite young, with lots of potentials. If I can get his body, then I will be able to grow even more powerful."

Orochimaru licks the blood on his face and walks towards another test subject.

Slither… slither…

A small white snake coils around Orochimaru's leg and reaches to his ear.

Flicker… flicker…

The snake flickers its forked tongue near Orochimaru's ear while Orochimaru is pouring some liquid in one of his test tubes.

"Oh! Looks like that little toy of mine has information for me. What was his name… hmm… Kabuto, was it? Let's meet with him."

Orochimaru prepares to walk out of his hideout.

Achoo…

He sneezes violently.

'Looks like someone is talking about me behind my back.'

---------------

'So, I was right. That purple cloaked guy is still alive. But a demon, I never expected him to be a demon.

Well, Danzo could be wrong since they termed all the horned beings as Demons and even Otsutsukis have horns.

If he is after me, then why would he help Danzo and send him after me? He is powerful enough to bitch slap me and take away the 'Grimoire'.

Well, I can think about that later. For now, let me kill Danzo again. This time, I will erase him from existence. Time to go full power.'

Izuna claps his hands together.

'Limbo Hengoku'

'Power Release: Chakra cloak'

Some orange chakra flames rise from Izuna's body and empower his Senjutsu cloak further.

Haa…

"It's a futile attempt. Give up, Izuna Uchiha. Accept your fate."

Danzo stretches his hands in front of his chest. The strange marking extends to his hands and forms two Diamond Shape marks in the middle of his palm.

Light chakra gathers in his palms and forms a blinding sphere of light. Danzo directs it towards Izuna and shouts,

'Light Style: Salvation Bomb'

Shoom…

The light bomb travels extremely fast towards Izuna. Izuna looks at the light bomb aiming for him.

'Looks like my conjecture is correct. Danzo received quite a help from that figure. But if he thinks I will go down this easily, then he is sorely mistaken.'

Izuna infuses darkness chakra in his palms. The black chakra rotates in his hand form a compressed spiral of chakra.

'Darkness Style: Blackout Rasengan'

Izuna throws the Rasengan at the light bomb.

Boom…

Both jutsus collide with each other and their respective elements clash with each other. The polar opposite elements create a violent reaction where one side turns dark and the other side shines brightly.

Bzzzt…

Black and white lightning crackles around their center and the jutsu collapse in itself. The blast releases a violent shock wave, which pushes them back.

'Earth Style: Rock Dome'

Izuna creates a dome to block the shock waves of the attack. Danzo is blown away by the blast. He grabs holds of the Rashomon gate and takes a foothold on it.

--------------

Outside the barrier,

The Sensing Sphere distorts from the massive amount of chakra. Its shape distorts to that of a funnel before the sphere collapses. The ���Sensor Corp' tries their best to prevent it, but the backlash from a sudden Chakra outburst pushes them back.

Some 'Sensor Corp' members even bleed from their nose. Their vision is blinded by a radiant display of light.

Rumble… Rumble…

The brilliant display of blinding light is followed by a massive earthquake. Hiruzen and others manage to stabilize their footing during the shock waves.

Sigh…

"At this point, I really want to know what's actually happening inside this damn barrier."

Hiruzen curses in frustration.
