(Story Start)

(Opening - Last Stardust - Aimer) (World Of Akame Ga Kill)

Within a corrupt world once laid an empire that was just as corrupt. Slave Trading, rape, murder. All of these things happened within the walls of the capital. Yet at the same time, within the Capital, there was a group who fought against the way of the Captial. A group of assassins called Night Raid.

Within the walls of the capital in the center area, a young man with hair as white as snow with two different color eyes, three whiskers fade marks on each sides of his cheeks, and pale skin. His left eye was piercing crimson with four-star slit pupil and the right eye was a calm ocean blue. He had lean muscle build. He wore a blue trench coat and black battle gear, being a combat shirt that has long selves, gloves, pants, and boots. On his hip katana with a red guard and a diamond pattern on the hilt, a short sword with a chain coming from the end of it's hilt and a silver case that holds a gun with different parts on his back, and a black belt that carried a few other things.

This was Naruto Einzbern. A Counter Guardian and member of Night Raid.

How did Naruto become an Einzbern, or a Counter Guardian or even end up in this world to begin with? Well let's start, shall we.

It started when Naruto had defeated Kaguya and won the fourth Great Ninja War but instead of being hailed as a hero, he was betrayed by the ones he calls friends. Sasuke had killed Naruto in order to achieve his dream of revolution. Not knowing the events he had set into motion. Upon Naruto's death, Sasuke felt as all the power he had obtained alongside Naruto was stripped from him. This led to him being captured by the other villages and some others that cared about Naruto. While Naruto was sent to something special. Instead of ending up in the afterlife with his family, Naruto's life was recorded within the Throne Of Heroes. He himself, becoming trapped within it.

The Villages that joined together to capture Sasuke had their revenge on him. Burning him at the stake as he watched the Leaf burn before his eyes. After the leaf had been burnt to the ground, His eyes were ripped out of his skull and the fire started engulfing him., slowing dying within the flames. Some of the villagers got out and made peace with those who killed Sasuke, in order to live a calm and peaceful life.

Naruto didn't know how long he was within the Throne Of Heroes. He wandered and Wandered within a barren landscape. Always coming to stop on top of hill, surrounded by swords as the winds blew around him. His eyes catching the large sun that shined brightly within his wasteland before he found himself wandering once more.

...

Days

...

Months

...

Maybe years?

...

Naruto didn't know or care as he fall onto his knees. Tears welled within his eyes as he realized how useless it was. To forever wander in this cursed life. He cried in both anger and sorrow at the idea of this eternal hell.

His cries were heard from two beings that took great pity for the young blonde and come up an idea that might help him.

Justeaze Lizrich von Einzbern, the Light of the Grail and Angra Mainyu, The Darkness of the Grail. The representations of light and darkness appeared before Naruto and helped with his sorrows, starting the healing process and helped him move on.

Soon enough, the two came up with an idea for Naruto, by becoming the first Counter Guardian that is bounded to the Grail and tasked to protect the world and it's future. That also means the humans that live in and can decide on how to reach that path.

Justeaze had once said this to Naruto.

"From now on, you will no longer be Naruto Uzumaki, the hero that is fated to have a curse life and sad path to his own death. You shall be Naruto Einzbern, The Hero and Sage of Hope that is fated to make his own path and change the fate of not only those around him, but his own fate as well."

On that day Naruto Uzumaki had died in every sense of the word, and Naruto Einzbern was born.

Born to live his life where no one can control him, nor where his life would end as a sad one. He was now his own person and will make his path however he sees fit.

Now that's out of the way, let's get back to story.

Naruto shook his head, ridding himself of thoughts of the past and started to head back to mansion that he and his girls live at. Yes, girls as in more than one, meaning a harem and they were fine with sharing him.

Hey, a Counter Guardian life was a hard one and can be tough, but Naruto keeps going with hope and strength in his heart. The girls who he met are ones he loves with all his heart. Even spending his days off with them. Unfortunately though, this is possibly one of the last times he would see them for a while. The latest job he had taken is taking him far away.

The white-haired guardian finally arrived at his home and opened the door to see two of his girls resting from their training routes.

"Hey Sayo, Spear." Naruto greeted with a smile on his face and got the girls' attention to look at him.

Sayo was a young girl in her teens with long black hair and eyes. She wore a white butterfly of flower hair accessory and plain cream-colored robes. She was a girl that Naruto saved from a sadistic family and two became great friends that which later formed into lovers.

Spear was a young girl in her teens with long blonde hair and blue eyes. She wore a black shirt, pink skirt, light pink leggings, winter boots, and large hat. Her winter coat was hanging on a coat rag nearby. She was the daughter of the former Prime Minister and would have died with her father, but an A-Class Danger Beast attacked and allowed her to leave for somewhere safe.

After Spear was healed, she joined Night Raid and started helping them to end the corruption. She later met Naruto and the two became great friends that led too lovers.

"Hey Naruto." The two girls greeted their shared boyfriend/lover and walked up to him for a hug which he returns in kind.

The hug ended with the white-haired man putting his weapons down and sat with the girls in the living room.

"Anything new today?" Sayo asked.

"Nothing much but I have another task coming." Naruto replied, remembering his talk early morning.

"Oh, a task? What kind of task?" Spear asked, wondering what mission Naruto has.

"The away from home kind of mission." Naruto said as he let out a long sigh.

At that moment both Sayo and Spear know what their shared man they love met by that.

"Do the others know?" Sayo asked, meaning the other girls that shared Naruto.

"No, not yet at least. I will have to tell them when they are here," Naruto answered, knowing that he will have to tell the rest of his girls of the task he has to do. Something he wants to get over and done with quickly.

"Tell us what Naruto?" A female voice asked getting the white-haired person's attention.

The first was a young girl with long black hair that reaches down to her knees and red eyes. She wore a dark sleeveless mini dress with a white collar and red tie with a long dark coat over her shoulders, a red belt around her waist that has a red side skirt cover, red gauntlets and black gloves, long back socks and black shoes. She also has katana in its sheath that has a red plus sign guard and handle. This was Akame, member of Night Raid and one of Naruto's lovers.

The second was a young woman with short blonde hair that has two long bangs that frame the sides of her head and golden eyes. She wore a black tube top holding her breasts, a white scarf around her neck, gold armbands under her shoulders that had puffy sleeves to her wrists, white pants that had insides uncovered showing off upper part between her legs and black panties, a brown belt around her waist that had a round silver buckle and brown boots. This was Leone, member of Night Raid and one of Naruto's lovers.

The third was young girl with long pink hair in twin-tails on the sides of her head and pinks eyes. She wore a pink sleeved shirt with a pink tied shawl that has a high collar, a pink gown, and black shocking with pink shows. She also carried a silver case on her back. This was Mine, member of Night Raid and one of Naruto's lovers.

The fourth was young woman with long purple hair that reaches to her back and purple eyes with square glasses over them along with a scar on her right cheek. She wore a sleeveless lilac cheongsam that reached her calves along with having slits on both sides to her hips, a diamond window on the chest that seem to pronounce her breasts, with a detached lilac arm sleeves, white shocks that reached her highs and white boots. She also carried giant pair of scissors on back in its sheath. This was Sheele, member of Night Raid and one of Naruto's lovers.

The fifth and final was a young in her mid-twenties with short silver hair with a left light purple eye as she wore an eyepatch over her right. She wore a black suit that shows her cleavage, black shoes, and her right arm was a dark green mechanical one. This was Najenda, leader of Night Raid and one of Naruto's lovers.

Naruto had met them when he joined Night Raid, which Leone was the one that brought him in after seeing his skills first hand. He bounded with them on having step the way towards peace and freeing the Capitol from corruption. They were fine with sharing, just that their shared lover spends time with them equally.

Akame was the one that asked the question as she was the first one in with the others following behind her.

"I will tell soon enough but first, where are the others, Akame?" He asked with a small smile.

He couldn't see his three other loves that walked in and wonder why.

"Chelsea has been called in for a spy mission to make sure the Capital's allies are reporting in. Esdeath and the Jaegers have also had a mission that needs them to watch over the Western borders." Najenda answered as she walks to the kitchen for a drink, remembering some of her talks with the Emperor and fellow harem sisters had a while ago.

"I see, that's too bad. I was hoping Chelsea, Esdeath, and Kurome would be here before my next task takes place." Naruto said, hoping all his girls were here.

"Your next task?" Akame asked.

"Yes, but not for the Empire. But rather something else and they have called me," Naruto answered as he took a seat at the table and his girls did the same now understanding what he met.

It's no surprise that in Naruto's harem know all about their shared lover and what hell he has been through. He had told and showed them by a Memory Rune mark that shows any memories of who writes the mark to those who he or she wishes it. They have been there for him and helped the man they love healed fully from his past and the scars he gained. But let's move on.

"Oh, what task do you have again, Naruto?" Sheele asked honestly, getting everyone to sweat drop at this.

Sheele is an airhead and can forget some things.

"Sheele how many times have we told you this before?" Mine asked.

Sheele shrugged her shoulders.

"Like ten times now!" Mine stated.

"Calm down Mine, Sheele just forgets that's all and I happy to explain the task at hand as it not my normal ones." Naruto said with a smile on his face.

Mine crossed her arms but sighed, knowing that Naruto was right and couldn't be mad at Sheele no matter what.

"What is different about this task?" Najenda asked, remembering some of the task that Naruto has told them.

Naruto would travel to different worlds that needs him to fix it and bring balance for humanity to live in, having a light and darkness to live, because one can't live without the either.

"The task I have has me taking place within a Holy Grail War." Naruto answered, getting some shock faces.

"What a second, I thought you don't take those Grail Wars due too and I quote, 'Some mages bitch fighting over some wishing item that gives them their wish is not my kind of mission.' So why now?" Leone asked.

"True but I have a feeling that this task and Grail War will be interesting than the other ones I have done before. As the Grail War I am taking part is the Fifth Holy Grail War that has three different routes but with me there. A fourth route should appear." Naruto said as he saw multiple events play out before his eyes.

The girls understand that once Naruto was tasked and has his mission, he will finish it and do whatever he cans to bring balance to the best of his abilities. But they didn't like the idea of him having to leave for so long. And not knowing when he will come back will take a toll on them.

However, they know that Naruto will come back because he made a promise to them that he will never die or make them sad, but that he will keep on living to see them again and make it up to them.

"So when will you leave?" Akame asked.

"Sometime tonight, maybe tomorrow morning. I can't say for sure," Naruto replied, the best he could.

"Than we should use the time we have. I think maybe a good five class dinner and dessert of our choosing can help us pass the time and spend time with you Naruto," Sayo offered, getting Akame to drool a little in thought on having her lover's cooking.

Leone laughed a little before shaking her best friend out of her dream world and point at her chin, telling her she was drooling again.

Akame blushed a little before whipping her drool away with her right arm.

"I think that is a great idea. Akame will you help me with dinner...and not eat it." Naruto added as an afterthought knowing how his lover was.

Akame nodded her head in agreement as she takes off her coat, gauntlets, and gloves to put her hair in a ponytail and started to help her lover cook.

The others waited for dinner, being the last great one they will have for a while, but they have a feeling that Naruto will come back, knowing his luck. As for the white-haired man was not normal or special but just himself. He was just Naruto Einzbern, the Strongest Wielder of Incursio, Assassin of Night Raid, Counter Guardian from the Throne, Silver Dragon King, and the Hero of Hope.

(Days Later. Fuyuki City)

After spending the past few days with the others, Naruto left them. Bidding a solemn farewell to those he loves. He arrived in Fuyuki Japan. Currently the white haired counter guardian was standing on top of a crane as her looked around the city. His eyes catching sight of multiple things. A blue haired woman with Elf ears. A girl with white hair like himself wandering around the city as though it was a giant playground. Closing his eyes, Naruto turned them towards the residential district of the city before he started to shimmer. Blue lights shattered away from him like glass revealing Naruto in a different look. Both of his eyes were his original shade of blue while his hair remained the color of snow. As he looked around the city, multiple scenes played within his mind. All concerning a teenage boy with orange hair.

"This situation has been played out in three different routes. And you Shirou Emiya have been a part of all of them. Whether you wanted to be apart of this war or not...the decision was made by the grail itself. Count your blessings while you can." Naruto spoke to himself before he noticed something strange.

He was able to see the beginning and end of the three routes concerning Shirou Emiya within this grail war but for some reason, at this very moment. The end was lost to his eyes, and the beginning was clouded.

'A fourth route now.' Naruto summarized to himself in thought. "You can come out now." He called out to seemingly no one.

"Just who are you?" A calm voice asked him.

Turning around, the agent of the grail came face to face with the Caster servant of this war.

"An observer." Naruto answered plainly as his sword appeared in his hand.

"I find it strange how an observer like yourself is able to release the same type of feeling that servants give off." Caster said as Naruto could feel her eyes narrow.

"I've been told that I'm a very special case...Medea." Naruto said, revealing the Caster's true name. "Worry not, I have no plans to go against you or anyone in this grail war for that matter. I've been sent to find information on something and I will do just that." Naruto said as he turned his back to the greek heroine as his weapon vanished.

"How do you know my name?" Medea asked angered at the observer for knowing something like that.

"I know a lot of things. I know you plan on summoning Assassin to your side as a bounded wraith." Naruto revealed as he didn't move an inch. Showing some strange form of trust.

Caster looked at the white haired man's back with a glare before she left. Leaving him to his own devices and to devise a plan to take him out should the need arise.

Sensing as the servant vanished, Naruto let out a sigh as something caught his eyes. An orange haired teen girl with a modest sized chest was walking next to a purple haired girl with matching eyes. Both wearing the same uniform as Naruto shook his head.

'A sister perhaps?' Naruto thought to himself as he had to shake off a bad feeling. 'Something is wrong with this war. Something big.' He finished off as he disappeared from the crane. Starting to plan his move

(END)

Dante: So in this as you can see. Naruto is a counter guardian that has traveled to the Fate/Stay Night world during the fifth Holy Grail War. Now within this, while Naruto is technically counted as a servant, he leans more towards being a demi-servant that interferes. If Naruto had to have a class for this, he'd be more of a Ruler class. So Naruto will have a total of 5 noble Phantasms. Hopefully you guys enjoy this one. I do have more stories on the way so see you in those updates.

Incursio, Murasame, Pumpkin and two others.

Naruto's theme is Brave Shine by Aimer.
