Story Start!

She loved the Underworld.

It was her home, she had been born here, raised here, and one day she would have expected herself to die here. Rias' loving family had always been there for her, her peerage was the extended family that she loved with all of her heart. She would have never thought in her life that she would have made a mistake like this.

The day that she forced Naruto to make a deal to join her peerage, was the day that she doomed the Underworld.

She made a mistake.

The Underworld was a sea of flames now, with corpses everywhere. Naruto wasted no time once he had become a Devil King to wage an instant war against the rest of the Underworld, and he used tactics that nobody could have expected. Tactics so dark and evil that no matter how strong his enemy was, they could not stand before him.

Her brother, her only brother, had been slain.

Killed in his sleep by his own son, and his wife had been slain with him. Naruto's act of mercy in bringing Serafall back to life had been just that, an act of mercy for a foe that he didn't need to kill. Every person who stood against Naruto found themselves in the worst positions imaginable. Naruto had not ordered this action, it would seem that even Naruto had been displeased with Sirzechs' murder, but in the end it served his purpose.

The 72 Pillar families were destroyed, the remaining ones who didn't surrender to him.

ALL of the children of the Underworld were possessed by the spirits of Jack the Ripper, and Naruto declared as such. To attack Naruto was to mean to kill all children in the Underworld, which even the most evil of devils couldn't do.

The Low and Middle-class Devils didn't even try and fight.

They joined Naruto when he granted them their freedom, and now all peerages were free from their masters. It took no time at all before all the wicked and cruel devils with peerages were absolutely slaughtered by their recently freed peerage members who they abused.

Soon enough, the war became something impossible to win.

"He... he conquered my home..." Rias could only watch her family home burning, her mother, father, and those who served the family were outside of the home. As a sign of power, Naruto ordered all High and Ultimate-class Devils of the 72 Pillars who had intitially rejected him command have their homes burned to the ground as a show of dominance over them.

They couldn't fight back.

Her family put up no resistance to Naruto at all when they realized how hopeless it all was.

2 days.

Naruto conquered the Underworld in less than 2 days after being crowned Leviathan, and the other Devil Kings had been slaughtered for putting up resistance. Without Sirzechs, the two remaining Devil Kings could not offer any real threat to Naruto's armies and his own threats.

Naruto had 500 women killed instantly, and he gave out the threat that he could slaughter every single person in the Underworld with his army of children assassins. If that wasn't enough, Naruto had nuclear warheads that were hidden all over the Underworld just waiting to be used to wipe out any forces that could resist him. Jeanne d'Arc and her holy powers, and his Lancer, had made quick work of Ajuka when combined with the fact that Naruto had an army of assassins of great power, the entire Fallen Angel forces, and Atalanta using long distance arrows to bombard him from miles away.

Rias had sought to use Naruto's power to end her marraige to Riser, she had tried to manipulate him for her own gain.

In doing that, she lost almost everything.

"It's... it's all my fault... Earth being conquered, the Underworld being conquered, the Fallen Angels following him, the Vampires being enslaved... it... I didn't see any of this coming... Mother... Father... was this why the Uzumaki clan... was this why they were destroyed?" Rias asked as she gripped her hands into fists.

They heard footsteps on the grass.

"... We don't know..." Her father lamented with her and placed a comforting hand on her shoulder.

"Rias Gremory! I, Ushiwakamaru, have come to bring you a message from my Master!"

There was silence when they turned around and saw one of Naruto's servants.

"... What... what more could he possibly take from me? Haven't I suffered enough?" Rias asked with tears starting to gather in her eyes.

"No, you haven't... my Master loved only 1 woman in his heart, and it was you who twisted that love for your own purposes. Assassin told me of your manipulations, either way the Queen of your peerage, Akeno, has been put to death by my hand this morning. He wishes to pass the message to you that she attacked him of her own free will, and you will not be punished for her mistake." Ushiwakamaru spoke with a proud smile on her face.

Akeno had tried, this morning, to kill Naruto with a stealth attack, but that wouldn't work with her there.

Rias collapsed to her knees.

"She..."

"I made sure her death was as swift as painless as I could make it, though I don't care if that comforts you or not. I am here to give you a warning, if any of you retaliate, then your deaths will be next." Ushiwakamaru gave her message, and then she turned around and started to walk away.

Her mother hugged her as Rias screamed and cried on the ground.

For Rias, this had been a bad end.

-With Naruto-

"This was too easy! I can't believe it, your plan worked without a hitch! I'm very proud of you Naruto... My Lord..." Ravel spoke as she gave a more respectful, if not attempting a seductive, bow to Naruto. Naruto had destroyed the 4 thrones of the Devil Kings and had created a new throne from the destroyed remains.

Naruto didn't seem happy.

"... I was hoping they would fight back more..."

"... Naruto?" Ravel asked as she heard that strange tone in his voice.

Naruto's throne room was literally covered in the corpses of many people who had attempted to assassinate him this morning. All of them having been killed quickly and painlessly, but without any mercy at all.

"I'm the King of Earth and the Underworld, and with all of the forces I have amassed, I will easily conquer Heaven. I don't even need to plan to do it, it could be done with a single large scale assault now... you could say that I've done it, I'm at the stage where I've become... Atalanta?" Naruto asked his second Archer as she looked out the window.

"A small rebel force is sneaking through the forest."

"Wipe them out." Naruto gave his order to her with a wave of his hand.

She took out two arrows and loaded them into her bow, before she aimed into the sky and fired. Soon enough, a rain of arrows that were as many as the number of stars in the sky, started to rain destruction and explosions onto the forest that the rebels were trying to use to hide.

"Enemies are wiped out."

"See, nobody can match you. You're the perfect king, unmatched, who can promise victory in every battle... you have become a living legend. You can take on the entire world and win, and now you've done just that, twice over... what is there not to celebrate?" Ravel didn't see why he wasn't excited about this. He had achieved such amazing results in such little time.

He was the human form of victory.

His allies need not fear failing, and his enemies could only hope for a swift defeat of their side.

"The problem is that I only achieved this as fast as I did thanks to the fact that becoming a devil allowed me to overcome the limits keeping me down. I owe a large part of my victory to Rias Gremory... and I'm not satisfied with that. Foreigner, Abigail Williams." Naruto stated as he summoned her.

"Yes Master?"

She appeared.

"Do you know what multi-verse theory is?" Naruto asked her, and she shook her head. "Every choice, every action, creates a seperate reality in which the results of that choice take place. In one world, I killed Akeno with my fist, in this world Ushiwakamaru took her head off of her shoulders in one clean blow." Naruto explained to her.

Naruto raised his hand and summoned Featherbreast.

"A chicken?"

"A Phoenix, a unique Phoenix that has the ability to store inside of it's tears the memories of others. In another Universe, this chicken used her tears to awaken the memories of another version of me when his timeline got reset. I've tasted one of these tears, and I got the memories of that version of me." Naruto explained for Ravel when she questioned why a chicken had been summoned into the world.

"Ah! That's the chicken... that's the chicken! That's the Miss Featherbreast the First, my Outer God told me about her... she travels from timeline to timeline to meet different Narutos who will make use of her tears!" Abigail realized as she pointed at the chicken.

Ravel watched as Naruto cut his thumb and allowed Miss Featherbreast the First to drink a single drop of his blood.

"Now she has my memories stored inside of her... Lets face it, this world was no fun to conquer. I did everything far too easily... I want more of a challenge next time. Atalanta! Ushiwakamaru! Abigail! Atalanta and Ushiwakamaru, the two or you are to guard Abigail as she takes Featherbreast across space and time... find a version of me who was not manipulated by Rias."

"But... Master, if that you drinks her tears, won't he get your memories?" Atalanta questioned Naruto on that.

"I know myself well enough, he will agree with me. He won't see those memories as something full of hatred, he will see them as a second chance to build up a legend even greater than the one I've built up in this world... Atalanta, I'm going to keep working towards my dream in this world for your sake, for the sake of everyone who has crossed my path... be sure to help him reach for an even brighter future than this one." Naruto stated as he reached towards the sky. "As long as Rias does not try to manipulate him in his world, his path will become far different than my path... one day, we will see each other again, and I hope you'll have a great story to tell me." Naruto spoke as he walked out of the throne room.

"YES!" Ushiwakamaru bowed.

"I understand Master!"

"Master!"

"Naruto...?" Ravel looked towards Naruto with confusion as he had a wide grin on his face that was filled with life once more.

"Now come on Ravel, Heaven isn't going to conquer itself! Lets go, onward into the light once more, because I've got a throne to sit on." Naruto laughed as he glanced back.

Abigail opened up a portal, and she walked through it with Miss Featherbreast in her arms, with Atalanta and Ushiwakamaru following after her.

Naruto's laughter filled the castle.

It was time to make a better ending.

Chapter End!
Please Leave Me Lots of Nice Long Reviews, But No Flames Please!

You people DO realize I have been hinting at this right?
The Fate-series is a Multi-verse Theory series in basics, and Miss Featherbreast will always appear in stories that have had their timelines reset. She was literally given the power to grant memories to those when the timeline gets fucked with.

Naruto's Path to Absolute Perfection - AKA - The Bad End
The ending where the King had nobody who could challenge him, the ending where he conquered everything easily and without much effort. Pushing himself far harder than he should ever have to, because he couldn't stand being manipulated.
This Ending is achieved when Rias Gremory manipulates Naruto, if that condition is met and Naruto is forced to join her peerage through manipulations, thent his is the outcome.
