BECOME MADARA'S GRANDLE IN NARUTO WORLD
OPERATION BLACK ANBU

In the hidden passageway inside the hidden cave, the,

Kakashi and Izuna walk into the basement building with a large sign 'Anbu Black Ops' in kanji. They're inside Anbu headquarters.

We both walked to the counter near the heavy metal gate. Kakashi put the scroll on the table and we waited for an answer.

The masked Anbu took the scroll from the counter and retreated. We waited a while for Anbu. After a few more minutes, Anbu returned with two sets of equipment as she spoke,

"It's a set of equipment for you two." 

"Thank you!" we both thanked him as he continued,

"Replace your gear and meet the Captain in the next ten minutes."

We chose our set and moved to a remote corner of the building to complement our Anbu gear. The kit consists of an Anbu vest, a pair of arm protectors, a porcelain mask, and a high-quality knife.

After we changed gear, Kakashi knocked on the iron door a little. After a while, the door opened and an anbu led us.

"Through here, Captain is waiting for you."

We walked for a while inside the various hallways of Anbu Headquarters before we entered a room.

"Captain, the recruits are here." Anbu told the Captain when he returned to his job.

The masked Anbu walked towards us as she spoke,

“So, you two are the recruits recommended by Hokage-sama, Kakashi Hatake, and Izuna Uchiha. You both have the Sharingan and one of you even has the moniker 'Silent Shinigami'. 

Our Anbu is not a place for gentle people. This is the place where the darkness resides and many secret village missions are carried out. We are an elite division that only demands the best among the best. Both of you will be trained for a month in various fields and at the end of the training, you will be given a division based on your specialization.

More information will be provided to you by your coach. After your training, you will be stamped with an Anbu sign to inaugurate you as an official member of Anbu. Now, meet your coach.”

The captain simply steered us towards the training hall and left. After a while, an anbu member with a tall and large body appeared before us as he introduced himself, saying,

“I'm your coach for next month. Before we start, I want to tell you about the various divisions of Anbu. There are no ratings in Anbu and only your achievements and experiences define your hierarchy. Now, let's start with the introduction of the various divisions of Anbu.

There are seven divisions within the Anbu namely, the Falcon Division responsible for hunting nin-missing, the owl division responsible for the search for Stealth and Information, bear Division in charge of Protection and Investigation.

The Cat Division is in charge of Stealth and Assassination. The Frog Division is in charge of Medical and Crisis, they are Combat Medical Officers. The Wolf Division was responsible for Torture and Interrogation and the Dragon Division was in charge of the other Anbus Organizations and Collections.

There is another hidden division known as Root that is not part of normal Anbu. This is a separate division under Danzo-sama, one of the Village elders.

Now before we start your training, I'd like to ask the Anbu unit, you both want to join. It's necessary because you two will be trained accordingly. ”

“I will join Cat.” division I immediately reply to him.

"I'll also join the Cat division" Kakashi replied to Coach.

The coach looked at Kakashi's mask and hesitated for a moment before he spoke,

"It looks like you need to change your mask."

Kakashi wears a dog mash while I have a tiger mask.

"It's okay, I'll continue with this mask" Kakashi replied to Coach.

“Alright, then we will start your training. But first, let me tell you more about the Cat division.

The Anbus of Cat division can be created as Assassins. They showed their strength through stealth and quick killing. These were heavy duty members as they were required to kill any strongman. As a member of the Cat Division, you must enter and exit without ever being caught, without ever being known and no signs of your work will be traced back to the Village in case of an investigation.

For the next month, I will train you in stealth and stealth killing. Before we start, show me your hidden ability.”

I made a Ram seal as my body started to fade away,

'Lightweight Style: Camouflage Robes'

I disappeared from Coach's sight as his mouth gaped. He frantically tried to look for me, but after searching for a while, he was unable to find me.

"The good boy! Your stealth skills are the best. But I want you to hide your presence without using Ninjutsu. Only when you become one with the shadows without using any Ninjutsu will your stealth training be counted as complete. Anbus faces a variety of situations where they cannot use Chakra or they can warn the enemy sensors.

I reappeared before he asked me again to hide from his senses. This way both of our Anbu trainings begin. Kakashi and I quickly learned. Within a month, we both mastered all of Anbu's Techniques and skills.

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

After a month, Coach nodded in satisfaction at us as he spoke,

Tatsu called another Anbu member who carved the Anbu tattoo on our left shoulder.

“Welcome to Anbu corps. You will both be assigned to the team soon. Follow him to meet your new team.”

We follow the man who branded us. This person was wearing a bear mask as he spoke,

“The people from this Dragon Division are quite a lot. They were dubbed as 'Worded Bards' among other Anbu. I'm Kuma and from today you will be Inu and Tora based on your mask.”

He took us to a room with the other Anbu members and spoke,

“Welcome to Team Ro, beginner. Now let's go to the Hokage Office. We will soon receive our mission.”

We all blinked as we moved towards the Hokage Office. We gathered at Minato's office as he began to explain,

“Recently, various reports of Shinobi attacks have been reported at the border. Many shinobi from small villages survived by taking advantage of the turbulent situation.

They do not want to be controlled by the fire, wind, and earth states. So, I have no doubt that they will continue to cause disruption. However, this peace was won through the sacrifice of many. So, we have to look after him. And for that, I will count on all of you.”

“Ya, Sir.” We all shouted in unison as we started moving towards the border.

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

The Land of Fire border,

In the watchtower of the Border Patrol team, three Konoha shinobi engage in battle against the Five Shinobi wearing Iwagakure shinobi suits. They will finish them off when our team interrupts them.

"Help, retreat!" enemy ninjas ran in the forest as we approached the tower.

“Thank you for that, it looks like the Hidden Stone has betrayed us.” One of the Jounins thanked us.

One of the anbu members of Owl's division took the shuriken and examined it.

"It's not the Hidden Stone Shuriken." Anbu concluded.

“You mean it's fake. Why should…" 

“Because of the rift between Stone and Leaf.” Anbu interrupted Jounin.

Kakashi jumps from the tower as he chases after the con men.

"Hey, don't chase them too far." The members of Anbu try to stop Kakashi. Kakashi made some signatures,

'Light Release: Chidori Lightning Cutter'

“I'll take care of it.” I jumped off the tower as I convinced my team.

'Quick Release: God's Speed'

I disappeared from their sight as I followed Kakashi. Kakashi begins attacking the impostors as he takes them out one by one. Kakashi takes off his mask as he prepares to kill the last Ninja.

"Sharingan, you are the famous cold-blooded Kakashi." the impostor trembled in fear at the sight of Kakashi.

When Kakashi was about to land a blow on the final swindler, I caught his hand as I stopped him from attacking.

“Stop Kakashi! We need to get information from him.”

I took off my mask as I calmed Kakashi down. At this point, the fraudster was having a breakdown when he identified me,

"The mutated wish, you are the 'Silent Shinigami' of the leaves."

"Oh! You know about me. ”

I walked towards the con man as I smiled at him.

'Genjutsu: Sharingan'

The enemy ninja began to tremble violently as he wet his clothes in fear.

"I don't even want to know, what kind of strange Genjutsu you put on her." Kakashi.

"Oh! He has become a Goblin Killer or not.” I answered Kakashi.

"Anything!" Kakashi returns the mask when our mission is over.
