Reborn in Naruto As Madara's Grandson

Swoosh… Fwoosh… Stab…

A dark blade coated in Darkness chakra stabs through Danzo's heart.

Barf…

Danzo pukes out a mouthful of blood. The darkness chakra corrodes his body and eats away his organs.

Argh…

Puss leaks from Danzo's body as he winces in pain.

"What? How… how is this possible?"

Danzo stares at the blade pierced through his chest. Black fumes rise from the blade.

"That previous jutsu didn't finish you off. How… how did you survive?" Danzo questions Izuna in a frenzy.

Rubble… rubble…

Izuna pushes away the nearby rubble and walks out from the Rock dome. Danzo's eyes widen as he points at a finger at Izuna.

"If you are here, then who attacked me?"

Izuna slowly walks towards Danzo.

"Death! Huh! You miraculously defied death once. But will you be able to defy it again?"

Izuna smiles at Danzo and draws another blade and pierces it through Danzo's guts.

"Don't worry! You won't be returning this time. I will obliterate your soul for once and all."

Stab… stab…

Izuna ignores Danzo and continues to stab the darkness coated blade through various parts of Danzo's body.

'I hope this darkness infused blade will be able to keep his regeneration factor at bay. If I remember correctly, his regeneration is similar to that cloaked guy. So, it uses Light-based chakra to heal from fatal wounds.

But Darkness Chakra can interrupt this healing. I have to separate his soul from his body and to do that I have to first destroy his body.'

Aaah…

Danzo riles up his chakra.

Throb… throb…

The Fuinjutsu seal on his chest beats violently. It jumps out of Danzo's chest and targets Izuna.

"What the fuck?" Izuna jumps back in surprise.

He manages to avoid the assault of the seal. An eye opens up on the seal and flashes a yellow light on Izuna. Strange curse marks appear on his body.

"What is this? I am sure I avoided that freaking thing."

The seal extends all over his body and paralyzes him.

Clank… clank…

The 'Sin Grimoire' shakes furiously. Strange markings appear from the 'Sin Seal' and they start to neutralize the paralyzing seal.

Haah…

Danzo frees himself from the bindings of Limbo and quickly arrives in front of Izuna.

"This seal will be able to hold you for a few moments. It is enough time to end you for once and all."

Haha…

"Finally, I will have my revenge."

Danzo grabs the strange seal eye and slams it towards Izuna's chest.

'I will be a goner if that hit me. Think Izuna... think. I have to think of a solution to escape this predicament.'

Izuna churns the gears of his brain.

'Got it. I am an idiot. Why I never thought of this before?'

Izuna clicks his right molar.

'Substitution Jutsu'

Swoosh… Shoom… Slam…

Danzo slams his palm on Izuna's chest. Various sealing formula erupts from the seal and binds Izuna's body.

"Farewell, Izuna Uchiha. This is what you said to me right. I will throw them back at you."

'Haha! Now I will be the sole leader of Konoha. No! the entire shinobi world. All five nations will bow before my might. I will deal with Hiruzen after this, and I will force other clan leaders to submit to me. Haha…'

Danzo fantasizes about his sunny days.

"Darkness Release: Big Blackout Rasengan"

Slam… Bam…

A giant fuming black Rasengan smashes into Danzo.

Shoom…

The Rasengan hurls Danzo in the air and explodes. An enormous amount of Darkness chakra invades Danzo's body and corrodes it inside out.

Gwaah…

Danzo pukes out black blood and weakly stares at Izuna.

"How?"

A weak shriek comes out from Danzo's throat. Izuna slowly walks in front of Danzo. The light chakra continues to heal Danzo's body whereas the Darkness chakra erodes it.

Stuck in an endless loop of agony and torment, Danzo weakly questions Izuna.

"I have already fought with your so-called... Demon before."

Izuna slowly reaches near Danzo's body. He makes some strange hand signs and hovers his hand above Danzo's head.

'I hope it works. If not, I will haunt Fukasaku for providing me with 'Fake Scrolls.'

"Soul Art: Soul-body separation"

Izuna draws out a transparent apparition from Danzo's body. The apparition takes the form of Danzo. He surveys the apparition.

'Hmm… so this is how a soul looks like on closeup. This jutsu is similar to the Naraka Path power of Rinnegan. Naraka Path is more efficient, I have to say.

Well, I have to do it with this make-shift jutsu. If it works... it works.'

"No… Argh… no… don't kill me. No… don't."

Danzo's soul pleads hysterically.

"Did you spare the people you killed just now? You partnered with Akatsuki and slaughtered almost the entire clan, and now you expect me to spare you. Dream on!"

Izuna makes some more hand signs and claps his hands together.

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

Outside the barrier,

Tsunade clenches her fist and infuses a large amount of Senjutsu chakra in her hands.

"Sage Art: Heavenly Spear Punch"

Tsunade focuses almost all of her sage chakra on tip of her fist. The concentrated takes shape of a cyan spear.

Bam…

Tsunade punches the barrier with all her strength.

Crack… crack…

Various spiderweb-like cracks appear on the Green barrier.

Snap…

The green barrier shatters into countless shards. Tsunade continues to punch through the barrier. Her fist collides with the 'Demonic Rashomon' Gate.

Bam…

A giant dent appears on the gate as it protrudes out from the back.

Swoo…

The demonic eyes shine brightly and start to repair the gate.

"Not so fast!"

Haah….

Tsunade pushes forwards as she applies more force in her attack.

Bang… fwoosh…

She successfully blows away a giant hole through the Rashomon Gate.

Swee…

The light in 'Demonic Eyes' dims down.

Poof…

The gate disappears in a giant puff of smoke, and the barrier disperses.

Tsunade senses Izuna's chakra and quickly runs in his direction. Hiruzen and other Anbu members and clan leaders follow her.

All of them arrive before Izuna. His back is turned towards them as he held Danzo's souls.

"Are you alright, Izuna? You aren't injured, right?" Tsunade quickly questions him.

Izuna turns around and faces them. It surprises him to see the entire village gathered here.

"I am fine, Tsunade. Please quickly check on my clansmen. They need your medical expertise, Tsunade."

Tsunade nods her head and claps her hand.

"Katsuyu!"

"Yes, Tsunade-sama!"

'Immense Network Healing'

Tsunade infuses a large amount of chakra and sync with Katsuyu. Katsuyu splits into multiple smaller clones and spread throughout Konoha.

Tsunade heals the injured Uchiha clan members.

Hiruzen sighs and looks at the death and destruction around him.

'Uchiha clan is almost on the brink of extinction. I never thought such a thing will happen to one of the most powerful clans of Konoha.��

Hiruzen turns towards Izuna and questions him.

"Izuna-kun, do you know the culprit behind this massacre?"

"I do!" Izuna kicks the corpse of Danzo in front of Hiruzen.

"Your old and most trusted friend Danzo is the culprit. He joined hands with Akatsuki and slaughtered my clan."

"What… what are you talking about? Don't spout such nonsense and defame one of Konoha's elders." Koharu and Homura defend Danzo.

Izuna reveals his Mangekyo Sharingan to them and replies,

"You won't believe me, even if you see it with your eyes. Your blind trust in Danzo encouraged him to commit such treacherous crimes.

You may have spared him, but I won't spare him."

'Genjutsu: Sharingan'

"Watch his filthy deeds with your own eyes. Look at how atrociously he orchestrated a genocide in my clan."

Izuna grabs the soul of Danzo and shouts,

"Soul Art: Yin-Yang Release: Death to All Creation"

A formless power grabs hold of Danzo's soul. The pressure from the technique encompasses nearby onlookers. It forces all of them to bow on the ground. The elders caught off-guard face plants on the ground. The technique slowly erases Danzo's soul from existence.

The frantic shouts of Danzo deafen their ears. Hiruzen weakly looks at this scene and sighs.

"You reap what you sow, my friend. Perhaps I am a failure as a friend too. I wasn't able to pull you from Darkness and instead I pushed you into it."

Danzo's soul vanishes from existence.

Huff… huff…

Izuna pants from exhaustion. The previous fight has taken a toll on his body, especially the Yin-Yang technique.

'I am still far from 'Six Paths Power'. Only a single 'Yin-Yang' technique is my limit for now. Yin-Yang technique requires balance in all things, and so it is fundamentally different from elemental techniques.

My affinity for Yin-Yang allowed me to push this technique. But this is how far I can go without proper training.'

Izuna slumps on the ground. Tsunade immediately catches him and hugs him tightly.

'Aah! This is a blissful end at least for now.'

Izuna passes out in Tsunade's embrace.
