BECOME MADARA'S GRANDLE IN NARUTO WORLD
LAST MISSION

Three years passed in the blink of an eye.

Izuna has regularly conducted missions in Anbu. He has become Team Ro's Captain because of his contribution. During this time, he would occasionally train with Itachi and Shisui.

Itachi had graduated from the academy and had recently become a Genin. Orochimaru had fled the village when Hiruzen learned of his experiment. Kakashi was able to overcome his grief from the deaths of all his team members thanks to Izuna and Sakumo. Sakumo personally trained Kakashi and Kakashi to grow much stronger.

Initially, Kakashi faced many problems with the management of Chakra. Izuna solved the problem of draining the Chakra caused by the Sharingan. He created the Fuinjutsu seal to deactivate Kakashi's Sharingan. Kakashi must form a Ram seal to activate the Sharingan.

Kakashi still adopted the usual style of covering his left eye with a headband.

----------

Izuna lay on the training ground while monitoring the progress of Shisui and Itachi. Both of them had grown stronger than their Original counterparts thanks to Izuna's training.

Izuna will secretly train Shisui in the construction of Susanoo. Shisui quickly understood the technique and improved at high speed. Now, he can make the upper body Humanoid Susanoo.

'I have successfully mastered many other Kekkai Genkai natural Transformations. I had to figure out a way to learn Sage Mode. If I can learn the 'Six Paths Sage Mode' then I can easily cure Minato and Kushina.

'The Seal of Sin' has stopped bothering me. Half the Yin of the Nine-Tails provides enough Chakra to suck the seal dry. In my current state, I can easily defeat Grandpa Madara with his Eternal Sharingan Mangekyo. As for Rinnegan.

Right now I am the strongest shinobi in the Shinobi World, excluding Otsutsuki and that unknown cloaked person.'

A tremor ran through Izuna's backbone as she thought of the fight.

'Who is he? He was aware of this 'Sin Seal' and its power. I refuse to believe that I killed him with the attack.

I don't know how far he's going. But if I have to guess, then she is at least as strong as Momoshiki Otsutsuki. I wonder what happened to him after my attack.'

Izuna shook her head and silently stared at Shisui and Itachi's interaction. The young Sasuke walked towards him and lay down beside him.

"Izuna Nii-san, teach me jutsu. Dad won't teach me any jutsu, and Itachi Nii-san is busy training with Shisui Nii-san. Only you can teach me the jutsu now." Sasuke looked at Izuna with his puppy's eyes while puffing his cheeks.

Izuna poked Sasuke's cheek and replied, Izuna,

"Sasuke, you're only four years old this year, why do you want to learn ninjutsu so quickly?"

"Nii-san, I want Dad to praise me like Itachi nii-san. So, Nii-san, please teach me jutsu." Sasuke looked at Izuna with puppy eyes.

'Aw. so, sweet. I can't resist such a funny expression.'

Izuna pulled Sasuke's cheek.

"OK! I'll teach you 'Fire Style: Great Fireball Jutsu'. Later you can make Uncle Fugaku impressed with the jutsu. Now, follow me to the nearest lake. I'll show you a hand signal for that jutsu. Memorize and practice slowly."

Izuna walked up to the Uchiha lake and slowly made a hand gesture to his technique.

'Fire Style: The Great Fireball Technique'

He spewed out a huge fireball over the lake. A lot of lake water evaporates from the jutsu.

"It's your turn now."

Sasuke carelessly made a signature and spewed out a small flashing fireball moments before it went out. Sasuke lowered his head in despair.

Izuna rubbed Sasuke's forehead.

"Don't be sad, Sasuke. You did well for your first try. If you practice diligently, you will eventually reach the same level as me."

Izuna cheered Sasuke up.

"Come, I'll treat you to your favorite popsicles."

"Yay! You're the best Nii-san." Sasuke hugged Izuna.

Izuna and Sasuke walk through the new Uchiha complex while licking the popsicles. Izuna receives a signal from a member of Anbu who is hidden nearby. He stopped in his steps and urged Sasuke to continue,

"Sauke! Brother has some urgent work to deal with. Go and play with your friends. Also, don't be mean to Naruto. Don't let anyone bully him. He's my brother, just like you.

So, it makes you an older brother to him. Protect your brother from bullies."

Sasuke puffed his cheeks in annoyance.

"Nii-san, why do I have to keep the breed Naruto?"

"He was the son of my late teacher. So it's my responsibility to take care of him. If you take care of Naruto and protect him from the bullies, I'll teach you a lot of cool new jutsu." Izuna tried to seduce Sasuke.

"If you say so, I'll play with Naruto and protect him from the other bullies." Sasuke nodded his head.

"You can also call him during your training, I will teach you both. Now, brother has to go." Izuna disappeared from his place in the particle explosion.

"Wow! Very cool. I want to learn this jutsu." Sasuke looked with shining eyes.

Inside the Hokage's office, the,

Izuna appears in front of Hiruzen in her Anbu costume.

"You called me Hokage-sama." Izuna bowed in front of Hiruzen and waited for his orders.

"It's been four years since you joined Anbu. From a normal member to a Captain, your rank is increasing rapidly. I've accepted your request to retire from Anbu.

I want to know the reason behind the request. Your career as a shinobi is at its peak, and Anbu has no genius like you. It would be futile to release such talent from Anbu." Hiruzen looked at Izuna.

Izuna took off Anbu's mask and replied to Hiruzen,

"I had my fair share of bloody battles and missions throughout my career as an Anbu. I am tired of all this bloodshed and I want to explore the world outside Konoha. So, after retiring, I will travel across the 'Shinobi World'. '."

'Allegedly, I have reached a plateau in my recent growth. I have mastered and honed my skills in these three years. I am not a beginner with a lack of experience anymore.

I had to figure out a way to master Senjutsu or Sage Mode. I'll start with Shikkotsu Forest. Then there's a lack of the right summoning creature for me. I have not been able to make the right contract. 'Sin Seal' does not allow me to make a contract.'

Hiruzen pondered for a moment before he replied,

"I'll process your request as soon as possible. But before you retire from Anbu, I have a final mission for you as Captain Anbu."

"Please, Hokage-sama! I'll finish the mission." Izuna nodded at Hiruzen.

"Hummmmmd... Amegakure has suffered from civil war since the Third Shinobi War. Hanzo rule in the Ame led to many bloody massacres and large-scale genocides.

Recently, a new organization called Akatsuki has emerged. You are aware of the fact that Orochimaru fled the village this year. I suspect he joined this organization."

Hiruzen took the file from the table and gave it to Izuna. Izuna skimmed through the files while listening to the details from Hiruzen.

"We do not have detailed information about this organization. But from our sources, we have traced the origin of this organization to Amegakure. Our previous attempts to gather intelligence failed miserably. All of our previous spies were MIA or were killed in a cold, bloody way."

Hiruzen passed another list with the names of the spies and the duration of their mission in Amegakure. Hiruzen.

"Danzo previously led his Root team to investigate the matter. But I have lost faith in him after his recent attempts to kill me. He has been very power hungry for years. But I can't get rid of him, his Root is too important for the survival of the Village."

Hiruzen sighed and reminisced about his past.

'Sensei! I've failed in the last mission you gave me. Danzo became the village's darkness, but he was slowly consumed by this Darkness.

I couldn't force myself to kill my student and now my lifelong friend. I'm too soft-hearted.'

Hiruzen took a deep breath and continued.

"I've issued this secret mission to you. This will be an infiltration mission. Breaking into Amegakure and gathering intelligence about Ame's current situation.

Also, remember. If the situation becomes too dangerous to continue the mission, immediately abandon the mission and retreat to Konoha.

You are the third person to master the 'Flying Lightning God Jutsu', your life is far more precious than any intel. It will not be a problem for you to escape from the siege of the enemy. Now disperse."

Hiruzen rejected Izuna. Izuna disappeared from his place in the particle explosion.

"I'm still not used to this kid's technique."

Hiruzen slumped on the Hokage's chair and smoked from his pipe.

'Orochimaru! I hope I didn't make the mistake of letting you live.'

Hiruzen pondered while smoking from his pipe. He took out a drawer and took out a large crystal ball.

"It's time to see the development of Konoha's new seedlings."
