BECOME MADARA'S GRANDLE IN NARUTO WORLD
UNKNOWN ATTACKER

Obito and Black Zetsu immediately fled the situation.

Minato was involved in the fight against the Nine-Tails. Reserve his chakra a little from the previous fight. Nine Tails prepared another tailed beast ball to shoot the village.

'Callation Jutsu: Food Basket Crushing Technique,'

Minato summoned a giant frog on top of the Nine-tailed and crushed it on the ground. Minato teleported to Kushina and the newborn Naruto to check on them. Kushina clutched his hand and nodded at him.

"Are you sure, Kushina? You just gave birth to Naruto. You are very weak now. Also, a powerful enemy kidnapped Izuna. The village is on the verge of collapse." Minato asked him.

"That's my biggest reason for sealing the Nine-Tails. We have to save Izuna after that."

Kushina walked out of the secret room with baby Naruto in her arms.

'Adamantine Sealing Chain Barrier,'

Kushina combined the Adamantine Sealing chain in the barrier to hold the Nine-Tails together.

"Minato, I will use the 'Four Symbols Seal' to seal back the Nine-Tails inside me."

Kushina shed tears as she tried to convince Minato.

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

Meanwhile, in the sky of Konoha,

The cloaked man held Izuna in his hand. He grabbed Izuna's right hand, 'Sin Seal' visible to the naked eye. A similar seal appeared on the left hand of the cloaked man.

A small chain came out of its seal and entered into the Izuna seal.

Aahs…

Izuna cried out in pain, her soul began to be torn from her body. The cloaked man drew a transparent appearance from Izuna's body.

"You will soon be out of your misery. Such a dominant power is not meant for you who are like insects. Let this power return to its rightful master."

The chains around the Grimoire trembled. The cloaked man pulled the Grimoire out of the separate room and examined it.

"Hm... Still not complete. Only two eyes were around the seal, the rest were still missing. It makes things more complicated. I think I'll collect the rest later. For now, these two are enough."

The cloaked man pulled the Grimoire as the chains around him broke.

Aah…

Izuna groaned in pain and struggled desperately. The Seal of Sin in Izuna's hands was active and tried to fight against the chain of robed men.

"A futile effort!"

The cloaked figure suppressed the seal and gave a final push to tear the Grimoire apart. Izuna's consciousness faded.

'No! I can't die like this. I haven't lived long enough.'

His desperate attempt to survive begins a change in the Mangekyo Sharingan and develops it further. The Silver Sklera forms three inner rings around its Mangekyo star shape pattern.

Aahs…

A large amount of chakra churned in his body. The power from the sudden explosion of the Chakra pushed the cloaked figure and formed the intact body of Susanoo.

Many dark marks and totems emerged from the seal and covered Susanoo. The smoky Susanoo katana with dark chakra.

Cut…

Susanoo slashed a pair of katanas diagonally at the cloaked man. The cloaked man created another barrier around himself to block the katana, but the katana broke through the barrier like a hot blade cutting through butter.

A huge cross slash mark appeared on the chest of the robed man. No blood was spilled from the wound, the darkness broke the wound. The impact of the attack pushed the cloaked man towards a nearby hill.

Susanoo Izuna chased after the cloaked man. The robed man stood up slowly and broke his neck.

"I never expected such a situation. These insects could use the power of the Grimoire subconsciously. Still, if that's his best bet, then I'll end this soon."

The seal on the left ground of the robed man shone brightly and covered his body in a warm yellow light. This light removes corrosion from wounds and expels dark chakra.

A floating grimoire appeared beside him and healed his wounds.

Roars…

The damage to Izuna's Susanoo spread further and wrapped it in a black flame. Dark flames coated the katana and Susanoo swung it towards the cloaked man.

A large pale white barrier blocked the swing and drove away the flames.

The explosion…

Shockwaves from the impact of the katana flew nearby hills. A large narrow gorge appeared in his place. The cloaked man ignored the attack and floated higher in the sky.

Wings grew behind Susanoo Izuna, and he chased the cloaked man into the clouds.

The robed man created a huge spear of pale light and directed it at Susanoo. The spear shot at Izuna at high speed. Susanoo tried to block the spear with a pair of katanas, but they were broken in half due to the power of the spear.

The spear moved further and pierced through Susanoo and stabbed Izuna. Izuna spewed out a mouthful of blood. 'The 'Sin Seal' absorbed the blood and shone brightly.

Both of Sin's eyes were detached from the Grimoire and floated in front of Izuna.

'Limbo Hengoku,'

The two shadows of Limbo tore through the dimensional barrier and floated in front of Izuna. Sin's eyes shone brightly and clung to their chests.

Dark marks similar to Izuna appeared on their bodies and shrouded them in darkness.

Roars ... Roars …

The two shadows roared loudly and formed their own Susanoo. Susanoo they're smaller than Izuna. One of Limbo's shadows forms the Scyth of Chakra and the other Limbo forms a large sword.

The two disappeared and appeared in front of the cloaked figure and attacked him nonstop.

"Oh! You can even call Limbo Shadows from the 'Border Prison Dimension'. But your strength is still too weak."

The cloaked figure extended his right hand.

'Shinra Tensei,'

A great repulsive force pushed back the Limbo Shadow along with Susanoo.

"You may be immune to physical attacks and sealing due to 'Sin Eyes' but that doesn't mean you can change your nature."

Two clones of cloaked figures appeared beside him and engaged in battle with the 'Limbo Shadows'.

"In the end, they were still shadows and afraid of the light. Now let me take it back, what am I coming for?"

The cloaked figure disappeared and appeared in front of Izuna.

"Enough prancing, time to sleep."

The cloaked figure coated his hands with a strange white energy and grabbed the last chain of Grimoires that connected with Izuna's soul.

Aahs…

A great pain woke Izuna from her sleep. In a desperate attempt to preserve her life, Izuna clawed her left hand at the seal of the cloaked figure.

Aahs…

The light burned Izuna's hand and the darkness around her spread out.

Ha ha ha ha…

"Your Grimoire of Sin is a Dark Nature, and my Grimoire of Virtue is a trait of Light. They are opposite to each other. What are you trying to accomplish besides endangering yourself?"

Izuna continued to tightly grasp the seal. 'The 'Virtue Seal' in the hands of the cloaked figure activated and released a large amount of Light Chakra.

Izuna frantically absorbed this Chakra and her Susanoo changed again. The right side of Susanoo turns black from the dark Chakra, and the left side turns white from the Light Chakra.

'The Light-Dark Fusion: Cosmic Removal,'

Susanoo compressed the stolen Light Chakra and Dark Chakra in a large volatile sphere and threw it at the cloaked figure.

The cloaked figure was astonished at this drastic change.

"Here, how is this possible? Impossible, How can you combine light and dark?"

The explosion…

The attack launched a cloaked figure into space and exploded violently. The brightness from the explosion illuminated the sky for a moment.

Grimoire pulls back to 'sin Seals'. The Grimoire Chain had extensive damage to them. Susanoo disappeared and Izuna's chakra reserves reached their lowest point.

After spending the last bit of her Chakra, Izuna fell from the sky. His consciousness began to fade. Izuna forced himself to stay awake and focused his mind on the space coordinates near Minato's location.

'Flying Thunder God,'

Izuna sensed Minato's coordinates and teleported to him. They still had to deal with the raging Nine-Tails.

'I don't want Minato and Kushina to sacrifice their lives in vain. I'll protect them.'

Fwoosh's…

Izuna teleported from the sky and fell to the ground.

Nine large tails wrapped in 'Adamantine Chain' appeared in his vision.
