Author's note: So time to get serious. I've tried writing a story before, but my writing skills are mediocre at best, so after a few chapters of trying I ended up not satisfied with my work and abandoned the story, but this time is different, even if it's not extremely good I'm confident it will pass as decent.

Also as you will most likely notice english is not my main language so I apologise in advance for my bad grammar and poor vocabulary.

Btw if you didn't read the name of the chapter this is just the prologue, so I naturally is shorter than the future chapters, I will try publishing a new chapter once a week of at least 10k words, so yeah, enjoy!

Deep into the woods two figures could be seen one of them was a man, the other a woman, both of them laying on the grass, looking up at the night sky talking with each other, both of them had cuts and gashes all over their bodies, their clothes were torn and they look exhausted but, for some reason they had wide matching smiles.

The woman was stunningly beautiful, thin facial features, red slitted eyes, her hair was an alluring dark shade of red, and she was not extremely tall, but just tall enough to be considered above average. This woman is Kurama the ten tailed demon fox, the strongest of the bijuu, and the daughter of the sage of six paths.

The man next to her was handsome as well, sun-kissed hair, cerulean blue eyes, lightly tanned skin, his face has almost no baby fat on it, he was a few inches taller than Kurama, but like her this man was no ordinary person, he was Naruto Uzumaki, reincarnation of Asura Ootsutsuki, and possessor of both parts of the power of the Rikudo Sennin.

Now that the descriptions are over, let's pass on to the conversation our newly introduced characters are having.

"So we truly did it huh Naruto?" said Kurama panting a little bit "I gotta say I didn't expect it to end like that but I'm not complaining either".

"Yeah it was a... weird way to end a war but I won't complain, still… I can't help but mourn for all the people lost in the war, Kakashi-Sensei Sakura-Chan and Sasuke were the ones that hit me the most, it all happened so fast that I'm only beginning to understand the extent of the things that happened"said Naruto with a crestfallen expresión on his face.

At that moment several images came to Naruto's mind, he and Sasuke fighting Madara, the betrayal of Zetsu and the awakening of Kaguya, Kaguya killing Sasuke, Sasuke passing down to him his part of the six paths power, him forsaking his humanity in order to gain the necessary power to defeat Kaguya, in the process abandoning his physical body becoming a chakra construct like Kurama, Kurama absorbing the power of the ten tails, Naruto killing Kaguya...

"Hey Kurama?"

"What is it?

"I just want to confirm this but other than your bijuudama you have no other jutsu right?" Naruto asked with straight face

"Yeah well I've never really needed them, I mean normally my physical strength alone was enough to deal with most enemies so I never really bothered trying to use my chakra other way, why do you ask though?" Kurama answered

"It just occurs to me that if Kaguya was the one who brought us here and she is not here anymore, and you don't know other techniques aside from the bijuudama… Then HOW THE HELL ARE WE GOING TO RETURN HOME!?" Naruto finished with an extremely anxious face.

Kurama not worried at all simply answered "We will figure it out later, besides you have Sasuke's rinnegan wasn't he able to do space-time ninjutsu with it, with a little bit of good ol' training you should be able to do it too, more importantly, you noticed too, right? there's someone approaching right now, besides why would you want to return to that rotten world, I wanted to wait a little to tell you this but, I'll say it anyway, listen Naruto, with the war over and the people you held dearly dead there is no reason to return to the same world that rejected you before, that took out it's anger on you for something out of your control" finished Kurama.

Naruto with his head down, and his bangs covering his eyes, suddenly jerked his head up and shouted

"WHAT THE FUCK ARE YOU SAYING KURAMA, OF COURSE I HAVE TO GO BACK, IT IS MY DUTY... As the savior of the world, to take responsibility for saving something that was meant to end… It is what all my friends would have wanted"

His anger gradually receding, and taking on a more solemn look on his face, wich made Kurama take a more sympathetic one.

"Is it what they would have wanted though, to keep tormenting yourself, listen Naruto, even if you managed to go back, do you really think they would accept you as you are? Of course they wouldn't, maybe at the beginning they won't notice, but you have to remember you are not human anymore, and when they notice it it will just be the same as in your childhood all over again, and I don't want to see you like that again…" She said with a bitter smile.

"Kurama I don't know anymore, I just…" Interrupted by the rustling of the trees nearby get on his guard.

Slowly getting up then helping Kurama get up too, they took defensive positions and narrowed their eyes when they heard someone approaching, though they only heard him because of their heightened senses, the intruder was extremely stealthy and good at masking his presence.

"You hear it too, right Kurama" Naruto asked her through their mental link.

"Yes, this person doesn't seem to harbor any ill feeling toward us, but it never hurts to be wary, maybe you should try sensing her power level, with that sage-mode of yours" Kurama answered with Naruto nodding in agreement while secretly entering sage-mode.

"Hmm well…" *sigh*

"What is it Naruto?

"Her power is definitely not disappointing, I would even say she would be considered strong in our world, but when compared to us… even in our weakened state, she would not be able to do much damage, if any at all" Naruto said finishing with a sigh.

"Interesting, so we are too powerful or she is to weak, but I don't think it is the later, she gives off this feeling of accomplished warrior, I don't think she can be considered weak in this world"

Just when they finished their mental conversation, someone came out of the bushes in front of them, this someone was Grayfia Lucifuge a beautiful woman appearing to be in her early twenties, with silver hair and yes. Her hair, which flows all the way down to her back, features a long braid on each side with small blue bows at the ends, while the rest is let down, ending in twin braids. she is wearing a blue and white French maid outfit with long sleeves and a white maid headband over her head, with red lipstick as a cosmetic accessory.

"Do not move intruders, my name is Grayfia Lucifuge currently serving under the house of Gremory, you are to be brought to the HQ of the Anti-Satan faction to be interrogated about your presence in the underworld, if you come along quietly you might be given the chance to keep your lives" She said as multiple magic circles surrounded Naruto and Kurama.

"Kurama, you're right even before us she seems to be confident in her abilities, and has this leader-like aura, must be some kind of higher-up in the military." Naruto said telepathically to Kurama.

"She called it a faction, right? If there is an Anti-Satan faction there must be a Satan-Faction, a revolution maybe? that may be it, yeah, that would explain why she is so on the edge, she must suspect us to be part of the enemy faction. Kurama added.

"Maybe we should play along for a while, i doubt they would pose a threat to one of us, let alone both of us" Naruto continued.

"Agreed" and with that Kurama put an end to their mental conversation.

After deciding their course of action, both Naruto and Kurama raised their hands in submission before Grayfia approach them, with her magic ready, and put magical restraining cuffs on Naruto and Kurama, once she put them the cuffs, she summoned a teleportation circle and all of them disappeared in an instant.

An instant later at the Anti-Satan HQ

"So this must be the HQ of this woman's, Grayfia? HeadQuarters, hmmm, their architecture is really different from our world's" Kurama said with Naruto nodding in agreement.

You see, the building unlike what you would expect from a military faction, the building was a beautiful castle made of marble, with golden trimmings everywhere, gorgeous gardens on the outside, also everything in the castle seemed really expensive, that is if you assumed gold to be the base of this world's economy too, or maybe it was just as common as iron in this world, but still to Naruto who was trained as soldier and an assassin for all of his life, the mere thought of spending so much on something so trivial like this seemed ridiculous, glancing around Naruto noted that Kurama had other thoughts in mind, her eyes sparkling and a greedy look on her face.

"Figures she would react like that, well it's ok i guess with all her power there's almost no one who would deny her something" Naruto thought to himself.

Walking down the seemingly endless halls of the castle Grayfia suddenly came to a stop in front a huge iron door, gesturing for both of them to go inside they just entered the castle's dungeons with a lot of prison cells, guiding them to one of the cells and opening the door for them to enter, Grayfia gave them instructions.

"You will be called shortly before the faction council, with patiently here, the cuffs you're wearing will prevent you from using magic, so any use of teleportation will be blocked, in the extremely unlikely case that you were able to escape this cell, you would still have to evade the thousands of devils stationed here, in short every attempt of escape is futile" Grayfia told them with a cold glare.

"Understood ma'am" Naruto told her with mockingly, wich made Grayfia glare at him, and Kurama sni

"So, Naruto what do you think, about this people they seem off, they're definitely different from the humans in our world" Kurama complained mentally.

"Mmm, you're right they definitely are not normal, I don't know if you noticed but all of them seemed really young, maybe it's because this is the revolutionary side, and the revolutionary tend to be young people rebelling against the old system, but even then... this people are weird" Naruto said.

"Aren't you overthinking it, you did say it was possible, I don't know I've never bothered to learn human behavior… sorry for not being useful" Kurama said regretfully.

"Don't worry about it but I'm telling you this is really weird, have you tried sensing these people? They have this really weird energy, it's similar to chakra, well they have more of the yin part than the yang part but... I don't know it feels… foul" Naruto said.

"You should remember that I'm not really good when it comes to senses, well beside emotions that is, but now that I think about it that woman did felt off, her negative emotions where to strong" Kurama added.

"Yeah, but not only her, I can tell all of the people in this building are the same, they definitely are not good, they don't feel exactly evil either but, more like they can't control themselves.

"Yeah well anyway we prob...!" Kurama was saying before the door to the hall opened again and didn't get to finish what she was saying.

Grayfia came walking to their cell, she opened it and gestured for them to follow her.

"Because your entrance to the underworld was an anomaly and didn't seem to be intentional, we will let you after a brief interrogation after that you are free to go. Also the leaders of the faction were interested enough on you two anomalies that they decided to conduct the interrogatory themselves, you should feel honored, you get to be on the same room as the future leaders of the underworld" Grayfia said smirking.

To which Naruto answered with

"Yeah well, that's great and all but I've been meaning to ask you but… What the fuck is the underworld!"
