"Sasuke!"

"Sasuke-kun!"

Those annoying voices, admittedly clear from his two teammates, were the last thing he heard from his homeworld.

Kaguya, the rabbit Goddess, afraid of her impending defeat, used that damn time-space manipulation technique to separate him from Dobe, probably the only way to ensure her victory. Without him, it wasn't possible to use the sealing of six-path sage, possibly the only way to stop her.

Even more unexpected for Sasuke, it was to fall into a world inhabited by sentient beings with culture even more advanced than that of the Elemental Nations, much more advanced considering those iron things moving in the air without a hint of logic that he could apply.

"It doesn't make sense," Sasuke concluded after exhaling a breath of cold air. If Kaguya wanted to kill him, it would be easier to launch him into the vacuum of space, or onto the surface of a star. In either case, he could hardly survive long enough to find a way back, or for people left behind to help him.

"What about these people, did Kaguya know about them?" No matter how you look, clearly, they were human beings like him, at least the vast majority. Sasuke could see among them other beings who shared that same humanity but with the addition of animal parts. This kind of thing wasn't uncommon for Sasuke, but only because he studied under the tutelage of the most disturbed person who walked the land of the Elemental Nations.

"Faunus," Sasuke repeated the first thing he heard on the streets he fell on. "They asked what kind of Faunus I was..."

His eyes were unique, even in this strange world, he was immediately judged.

Luckily, being able to understand them was one of the few good things that accompanied him in this new world. He knew the language, it was a very rare one, used mainly for confidential communication in the lairs of Orochimaru.

"It's been hours..." Sasuke looked at the broken moon and the insanity represented by those fragments adorning the skies, a clear sign that he was no longer in his own dimension. "There is no sign of manipulation of space-time."

His Rinnegan could sense these fluctuations, possibly manipulating them if he had more time to study and test the limit of that divine eye. As such, Sasuke forced himself to remain close to his place of arrival and probable rescue point, or to continue the deadly conflict with Kaguya.

"What could have happened?" This question haunted him with its possible answers.

If Kaguya won, she would come after him to finish the job, cut the loose ends of her only possible remaining threat. However, nothing so far.

In case the victory, very unlikely, Sasuke could say, of Naruto, knowing that idiot, he would find a way to force Obito or Kakashi to tear to the dimensions after him. However, nothing happened.

Several hypotheses occurred to him, the most plausible, considering the face made with the effort and the remarkable drop in the absurd level of Kaguya's chakra to perform the technique, was this dimension too costly to be reopened freely even by Kaguya?

If that were the case, she would drain the planet of its life first, and then, if Kaguya still remembered him, she would put an end to his misery. Consequently, yet another planet would be devoured alongside him to try to satisfy the hunger for power of his obsessive spiritual grandmother.

It worried Sasuke.

The fact that he is the possible cause of the destruction of an entire world, caught in the middle of the millennial conflict of the Elemental Nations.

Confident as Sasuke was with his power, he recognized that he could not defeat that Goddess alone.

"Not the way I am, but if I have time..." A deep look at the moon's seal, entrusted to him by the sage of six paths, reminded him of his origins that transcended his own flesh. "The reincarnation of a demigod."

Otsutsuki Indra, Hagoromo's eldest son.

"I have potential." Sasuke could feel that he hadn't even started to scratch his limit, especially with his new left eye. "To dominate it completely, based on all the information gathered from Akatsuki leader, Pain, I would have a better chance against her, and also," he touched his chest, where his own sword had been used to pierce him in the heart. "Kabuto used cells from the First Hokage to heal me..." he could feel the power of the God Shinobi running through his veins. "Hashirama gave me a good amount of his Chakra just before he died. Maybe, just maybe, I can access part of his powers."

Madara, Obito, and even that piece of garbage, Danzou, could use the wood style, there was no reason for him not to achieve the same.

The possibility was motivational, managing to bring out the suggestion of a smile in Sasuke's downcast features.

There was still hope of fulfilling his dreams and saving that doomed world from perdition.

Considering the brutal amount of Chakra that Kaguya used to get rid of him, it must have weakened her considerably. That way, Naruto could hold it for a while. How much time? Sasuke had no idea. However, it could be madness based on a thread of hope that he didn't want to let go, but Sasuke believed that time was on his side.

"My Rinnegan, I'm sure it has space-time based principles. When I master it, returning to my world on my own shouldn't be impossible." Sasuke stood on the edge of a five-story building where he rested and walked, looking around for something useful. "If my eyes are not deceiving me, this world must be in a dimension where time flows differently; slower." He stopped, finding the most rudimentary and useful source of information in history; a library. "The fight may well be happening while I wait without doing anything."

Sasuke wanted to believe that this would be the case, so everything his brother sacrificed wouldn't have been in vain.

"Time to learn some things." Sasuke, tired of waiting, touching one of the wrist seals to retrieve the cloak he used to enter Konoha and revive the Kages, wearing it to help him go unnoticed. Although suspicious, it was better than the warm looks he received from women. "As if I didn't have enough problems, the women of this world are as thirsty as in the Elemental Nations..."

Sometimes, Sasuke wondered if his good looks were a curse or a blessing.

Sasuke descended into the nearby alley, but before continuing to walk, he made a casual seal and interrupted the flow of Chakra in his eyes. There was no reason to keep them active and spend even more energy, but something didn't seem to go as expected and the reflection of his face on a windowpane told him why.

"Rinnegan didn't deactivate..." Sasuke grimaced, the only thing that came out was the tomoes that adorned it. "Just my luck."

Sasuke took a deep breath and made use of his black locks to cover the divine eye. In the end, not having time to cut his hair in the last year turned out to be of its own use. With half his face covered with hair and a hood to complement, Sasuke only expected to have problems with authorities from that point on. Much better than being harassed at every step, or questioned and maybe even chased because of his eyes.

Night had come and not so long ago, so Sasuke didn't find it strange to pick up, which now turned out to be an open bookstore.

"Well, I would have gone in even if it wasn't open," he let those thoughts run as he entered the room and spotted a single person, a lone employee behind the counter.

"Welcome to the Tukson bookstore, all books in one place..." Tukson stopped at the end of his sentence, staring at the newcomer with sudden and inexplicable fear. Not only because of the appearance of a possible criminal but because of his instincts screaming danger. That single sample obsidian eye looked like a mirror of death. Then he heard the voice, strong and devoid of emotion, addressing him.

"History books, where can I find them?" Sasuke asked, taking a step towards the attendant, a robust man in his thirties, with short hair and a beard cut that reminded him of Team 10's Sensei. The most important thing about this man would be the fact that he was one of those Faunus, one who could very well hide his animalistic features from inattentive eyes, but not from an Uchiha.

Tukson took a step back from the request, demand, made by the client, a possible serial killer. His heart was beating uncontrollably, his throat was choking and sweat-drenched his back. He didn't have the courage to answer, nor to move. Unable to believe how he took that step, one that might as well have marked his destiny.

"I don't know why you're scared, but I don't intend to hurt you. I'm just looking for some books and maybe some extra information," Sasuke intoned slowly, walking to the shelves in an attempt to ease the tension.

Some time ago, when Sasuke had an unpleasant conversation with the nine-tailed fox, now named Kurama, inside Naruto, that walking mass of hatred claimed that his chakra was even more sinister than hers. Something to worry about, Sasuke had to admit, but at the time, being cold was a need to kill Itachi, maybe something even worse. In the end, after losing the curse mark, a representation similar to making a pact with the Devil himself, Sasuke sank further into the darkness and reached ridiculous levels of power, probably becoming the most funereal and sinister Chakra in the world. After receiving the Yin style of the sage, half the power of creation, Sasuke could only imagine what he was at that moment.

For a being with animalistic instincts, he should be something similar to incarnate death.

"S-Sorry..." Tukson tried, very hard, to regain some control, utter a single word, and point a trembling finger at what Death wanted.

Sasuke didn't press the man, he was almost feeling sorry for him; almost.

"The Remnant story…" Sasuke muttered the title and activated his Sharingan. The dynamic vision provided by his lineage facilitated learning to ridiculous levels. In five minutes, he went through the entire four hundred-page book and understood its contents.

Normally, Tukson would say that his store was not a library, but he was too scared to open his mouth.

"Grimm, Dust, Huntsman and Huntresses, Aura and Semblances ..." Sasuke went over the most important points learned and allowed himself to let the confusion take over for a moment. He put the book away and picked up the next volume, thus proceeding to the fourth where he got more answers than he would have liked.

"My revolution is flawed..." Sasuke put the book back on the shelf and leaned on it. Eyes open in contemplative realization, then his lips tightened.

Grimm, the creatures of darkness, was the sworn enemy of humanity and faunus of this world. They exist in different shapes and sizes, the vast majority represented with similarities to some living creature in the ecosystem, rarely humanoid, has been pressuring humanity to the point of having only four kingdoms. According to the books, these four kingdoms were something at the level of a Shinobi village equivalent to Konoha, apart from some settlements here and there being extinct too often to be recorded.

"And yet, they have time to fight each other..." Sasuke couldn't believe how stupid humans and faunus could be."When instead to come together to face the common enemy, theystill consumed by greed and quest for superiority while their existence is threatened!"

It irritated him, the whole story was practically shouting that his plans would not work. Even if it worked, it would be temporary.

"Mutual understanding is just idealism and illusion. Utopia doesn't exist." Sasuke knew that, his life taught him that Naruto's dreams couldn't work. The six-path sage tried, his son tried and so did many others after him, including the first Hokage. "Everyone failed, the only thing that has worked remotely up to now was having a powerful enemy to force the union in the midst of discord."

However, Remnant contradicted the answer that Sasuke got after talking to the old Kages.

Even having a common enemy, this world has gone through great wars and experiences an extreme racial division. All this while the possible extinction of life knocks on their doors day and night.

"Damn it!" Sasuke sank his fingers into the solid wood of the bookcase and Tukson lost his face color with the malice released by him. "What should I do, then?"

True peace was impossible. Everything was pointing to this unquestionable truth.

"No... there must be something." Sasuke breathed, calming the agitated Chakra inside him. He needed to be rational right now, not letting his emotions cloud his judgment. "I need more information... Yes, I need to better understand this world from the heart of the matter, and then, who knows, I Can be sure of my decision."

It wouldn't be wise to reach a conclusion based on a small series of books, whose opinion of the author could be somewhat biased, altering facts to benefit the point of view of one of the two races and the reasons for all these conflicts and instability.

Sasuke set a temporary goal. While there was time, he would learn more about this world and its reality while training for his eminent fight with Kaguya. He turned to the store owner, almost making the man collapse at the singular sight of his Sharingan shining amid the hood's shadow.

"Which one is the largest library in this kingdom?" He demanded. Illusions didn't seem to work here, something problematic, but nothing much. Apparently, there was no Chakra in this world, just a similar thing called Aura, and if his eyes weren't playing tricks on him, that aura was nothing more than pure spiritual energy, a very vast and strong one by the way.

As such, Sasuke determined that the people in Remnant had an incomplete form of Chakra, which hindered his illusion techniques, at least from the base Sharingan. He refrained from trying a more powerful version of his eyes. Illusions using Mangekyou, or above, infiltrated the opponent's body with the user's Chakra. It wasn't possible to know how this Aura reacted in contact with the Chakra, and Sasuke didn't want to test it on random civilians.

Tukson swallowed what appeared to be his own heart and did his best to gain control over his nerves near the collapse.

"Beacon's academy," he managed to utter and was relieved by the slight nod that Death gave him.

"Tell me more about this Academy," Sasuke continued to ask and the attendant looked at him as if he wasn't serious.

Beacon was one of the best-known places in the world. Not knowing about the most famous Academy to generate the guardians of humanity and faunus, was like ignoring the greatest source of energy in the world; the Dust.

"Hurry up." Sasuke hated being ignored, something he could effortlessly demonstrate in the sinister glow of his Sharingan.

"Y-Yes, sorry..." Tukson took a deep breath and did his best to answer. His life was at stake here! "B-Beacon is one of the four great training academies for new huntsman and huntresses," Death nodded and gestured for him to continue. "Beacon, in particular, is the largest of all, so it must have the largest literary collection in the Valley, perhaps even in the world."

"Good." Beacon just won Sasuke's interest. "And what are the requirements to join this Academy?"

Sasuke had been in one before, and as much as it was a waste of time, for the most part, it was undeniable that there was a lot to gain when you didn't know the world around you. If it were that big, it should have training areas and even accommodation to settle, something that would go well with his current situation.

"Eh?" Did Death want to become a student? Seeing that red-eye narrowing, Tukson cursed his tongue and replied quickly: "Documentation in order, being seventeen, knowing how to fight, having the Aura unlocked and I think have passed by a preparatory school!" he managed to say without stuttering and saw Death ponder his words and remembered something. "Oh, and it also seems to have an initiation test."

Tukson needed to thank Blake for telling him all this recently.

"Hn," Sasuke reflected briefly. He knew how to fight, he was sure of that. Age was a convenient coincidence, he was concerned that it was a children's academy, but it was a kind of graduate school. Fortunately, he turned seventeen a month ago, and even if he didn't, he would lie about it. As for Aura, Sasuke had something much better than that. The only thing missing was prior education, in addition to identification documentation.

"When does this initiation begin?" Sasuke didn't expect the big scared man to know everything, but it didn't hurt to try.

"In two days!" Tukson didn't even think and saw Death surprised and then suspicious. "A friend's daughter is joining Beacon soon..."

"Last question." Sasuke ignored the happiness and hope appearing in the eyes of his unwanted victim. "Do you know anyone who can put me on this exam in two days?"

Exceeding his expectations, the bookseller knew a certain owner of a nightclub in the center called Junior.

Achieving much more than he expected, Sasuke left the store, but not before putting some of the new coin he bought from people on the streets on the counter and seeing one of the greatest expressions of disbelief ever shown to him.

At the very least, this fearful cat thought it would kill him, but no more. Sasuke regained control over his actions and that included his nature of not killing unless necessary.
