Summary: What would happen if the Kyuubi sealing happened a little differently? What would happen if Naruto's seal was different and unstable, causing him to be sent through space and time into the Assassination Classroom universe? What would happen if he was found by an old assassin and trained as his apprentice before joining up with the rest of the class in Kunugigaoka Junior High in their mission to kill their teacher?

Warnings: Cussing, Fighting, maybe some Gore. Pairings undecided, though no yaoi.

Chapter 1: How it all Began!

Konohagakure, or the Village Hidden in the Leaves, was a powerful, yet peaceful village, home to many shinobi legends whose very names bring awe and inspiration to those who hear of them.

One of these legends is the famous Minato Namikaze, or Yellow Flash, who utilized his Flying Thunder God Jutsu to travel at light speeds to decimate an entire Iwa platoon with well over 100 ninja, with at least 2/3 of them being of Jonin rank or higher.

After the war ended, he was just another shinobi, though a very dangerous one for sure, living a normal life. That ended when he was appointed as the fourth Hokage.

There was a week-long celebration in honor of his monumental accomplishment, to go from just another orphan to become a Kage the likes of which haven't been seen for many years was a feeling he would never forget.

Another monumental event in his life was when his wife, a wonderful woman named Kushina Uzumaki, another powerful shinobi who had created quite the reputation as the Red Reaper of Konoha, announced that she was pregnant with his child. He couldn't believe it. He was going to be a father! So, they both spent the next 9 months preparing everything the child would need, from a nice room full of toys and books to planning out a training schedule for when he was old enough… yeah, maybe they went a bit overboard with it but what can he say, you only get to become a new father once in your life and he wasn't going to mess this up.

That image in his head of him and Kushina growing up while raising young Naruto, what they had decided to name their child, was shattered when he showed up.

The mysterious shinobi with the strange mask had just appeared into their secret pseudo-delivery room surrounded by his personal ANBU and killed the two nurses that helped deliver his child into this world, and had taken said child as a hostage.

"Step away from the Jinchuuriki, Lord Hokage. If you refuse, then your heir will know death after a whole 3 minutes of life." He remembered that voice, filled with such calm maliciousness that made him hesitate.

After freeing Naruto and teleporting them both back to his house, he quickly placed his child into his crib before grabbing his Hokage attire and equipment before flashing away to retrieve his wife.

When he arrived, he could only gasp as he witnessed the mysterious man rip the Kyuubi from its seal on Kushina's stomach.

As soon as he regained his senses, he was only just able to rescue the red-head from being squashed under the Nine-tails' clawed hand.

After that, he was forced to leave the fight with Kyuubi to his predecessor and his shinobi as he had to deal with the mysterious shinobi once and for all.

The ensuing battle was something he did not expect. This person could somehow turn himself intangible, leaving any physical attacks useless until he decided to become tangible again. That, combined with his Sharingan eye made him an opponent that could keep up with the fastest man alive.

The fight lasted about 15 minutes before Minato was able to outsmart his opponent and release his control over the Kyuubi, effectively causing him to retreat, leaving the Hokage to tend to the rampaging beast.

He quickly summoned Gamabunta, the boss of the toad summons, to delay the mighty fox while the blonde tried to think of the best plan given the situation.

The solution he thought of caused him to growl and clench his fist in emotional pain, surprising the toad boss as the Hokage was always upbeat and smiling.

He quickly told the summons to hold on tight to the Kyuubi as he flashed them away from the village, effectively saving the rest of the village from the fox's rampage.

Once they arrived at the destination Minato teleported them to, Gamabunta was forced to retreat into the summon realm as the Kyuubi broke free from his hold.

This was not a huge setback as Minato had prepared this spot specifically for the event that the fox broke free from its prison.

Suddenly, a large blue barrier shot up in the form of a pentagon around them. Surprised, the Kyuubi quickly spotted a large sealing array underneath it in the shape of a star, with the inside pentagon creating the barrier, while five of the Hokage's special kunai were at the star's points.

The Five Point Pentagon Barrier (a barrier of his own creation), while not the strongest out there, had enough power to contain any of the nine Biju for a limited amount of time, enough time for Minato to get his preparations ready.

The blonde Hokage quickly flashed back to his house before dashing from room to room grabbing scrolls, weapons, books, pictures, and clothes before storing them all into a small storage scroll before placing that scroll into a special storage seal on Naruto's small arm.

It was when he finished sealing everything that he actually looked at Naruto's sleeping face, causing the Hokage even more guilt. He looked so peaceful and calm.

Steeling his nerves, Minato quickly grabbed his child and gave Kushina one last kiss on the forehead before flashing back to where he left the Kyuubi to see that the barrier was almost completely demolished, leaving him only a few seconds at most before he had to deal with the beast again.

It was only when he went to summon a sealing alter that he noticed a tug on his cloak. Turning, Minato was aghast as he found his wife, looking half-dead, holding on to him for dear life.

"Kushina, what are you doing!?" Minato asked incredulously.

"You won't have enough *heave* chakra to do this, and I fear that *heave* even if I lend you my chakra, we will both be killed from chakra exhaustion…but, if this is the only way *heave*, then I will help you. We will seal the Kyuubi into him, and he *heave* will become the most powerful shinobi ever." Kushina rasped out as he managed to stand up with a little help from her husband, who had already set their child on the sealing alter.

"We just need to trust in Sarutobi-sama to look out for our son. With Hiruzen's guidance, I have no doubt that he will be an amazing shinobi." Minato smiled before starting the long sequence of hand-seals required for this sealing technique.

While this seal wouldn't cost him his life like the Reaper Death Seal, the chakra exhaustion he would no doubt succumb to would definitely kill him. The benefit of this seal was that while it provided the same protection for the host as the Reaper Death Seal, it allowed said host to determine the sanctions of the punishment. That way, if Naruto ever befriended or tamed the mighty beast, he would be able to better sync with its chakra and give it a proper home instead of a prison.

As he went through the seals he could feel his chakra deplete rapidly. That is, until he felt the comforting hand of his wife on his shoulder, slowly transferring her chakra into him so that he could finish the jutsu.

As soon as the Kyuubi burst through the now nonexistent barrier, Minato stopped his hand motions into a clapping motion before yelling out his last jutsu.

"Five Point Sealing Technique: Seal of the Heavenly Star!" with that shout, the sealing array that was spread out all around the clearing slowly started to condense around the sealing altar and up to Naruto's stomach.

The Kyuubi, while it looked like it was turning into dust and sucked into the sealing array, quickly realized that it was done for. In an act of desperation, the Kyuubi gave one last mighty roar before being completely dissolved into the glowing red seal.

"Looks like *cough* we did it, Kushina." Minato rasped out before falling to his knees, with his wife already laying on the ground, dead.

"Oh yes, you did it."

Minato's eyes widened in horror. No, not that voice. He had driven him away. No one can just come back from a Rasengan to the back like the one he gave him.

"I do commend you on forcing me to retreat, though I knew you would kill yourself in sealing the Biju. I just had to bide my time until you did." It was then that the masked man came around into his line of sight.

"What do *cough*cough* you want now?" Minato asked as he felt his life fleeting fast.

"Oh, I don't know, raise him and train him and force him to capture his fellow Jinchuuriki until he's the last one left. Then I will let him destroy this wretched place that took his mother and father away from him. Then and only then, will I tell him the truth and watch as his horrified expression leaves his face as I kill him." 'Madara' explained, loving the enraged expression on the Hokage's face.

"Now, I think I will take my leave." He said as he used his Sharingan to create a vortex over the infant, unknowingly putting it over the still glowing seal.

Just as Minato was feeling the last of his life leave him, his eyes widened once more as sparks started erupting from Naruto's seal, connecting with the vortex and creating a lot of wind.

"What the hell!" 'Madara' exclaimed as he tried to cancel his jutsu, only to widen his eyes as he realized he had no control over what was happening anymore. "What is happening you damned Hokage!?"

Before Minato could even respond (even though he physically couldn't), a large explosion occurred blinding anyone who was looking in the direction of the clearing and getting the attention of nearly everyone in the Elemental Nations, with Naruto in the direct epicenter.

When the light finally died down, the only thing left of the clearing was one large crater, measuring an area of about 100 acres and nearly 200 feet in depth.

There wasn't even evidence of a forest in the area of the crater, and sure as hell no evidence of a battle or any living being anywhere near it.

The civilians and civilians alike would go on with their lives, thinking that that must have been one of the Fourth's jutsus used to end the fox menace. They would go on to rebuild Konoha, eventually returning it to its former glory under the leadership of the Sandaime and eventually Kakashi Hatake, the Yondaime's last student alive, this time for real.

The Akatsuki would eventually be picked off one by one until it finally disbanded, showing everyone that Nagato truly did not have any plans of his own outside of what Obito told him to do.

Itachi eventually came back to the village after many years of getting the evidence needed to prosecute the village elders and everyone else involved with the Uchiha Massacre, as well as clear his name and apologize immensely to Sasuke for his transgressions, though the Uchiha youth immediately accepted and was just glad to have his big brother back again.

Danzo obviously resisted, even going as far as to declare a Civil War in Konoha, with him and his ROOT vs the entirety of Konoha's shinobi forces. Yeah, not a great plan. The rebellion was quickly shut down and Danzo's stolen Sharingan returned into Uchiha hands.

At Itachi's insistence, Shisui's body was found, though highly deteriorated, and properly buried, along with his eyes, in Konoha's hero graveyard.

Once he was old enough, Sasuke became Hokage to replace his old sensei, and led Konoha into a Golden Age of peace and innovation.

Things seemed to work out for the best back in the Elemental Nations. Though that's not where our story ends. Konoha was only the beginning.

The thing that no one seemed to question about the night the Yondaime died, was the fact that there was a survivor of the explosion.

Just because he wasn't in the Elemental Nations anymore didn't mean he was dead. On the contrary, he was healthy and full of life.

What the 'explosion' really was, was a rip…no, more like a colossal tear in the fabric of reality, made from the use of Kamui in such a close proximity to a seal that had yet to stabilize. The tear basically fed off the chakra coming from the seal until it amassed enough energy to detonate, causing it to implode and close the tear once more, though taking anything in its radius with it through the tear.

While normally, Naruto would've been consumed by the empty void he was sent to, if he wasn't obliterated by the implosion itself. This, however, did not occur.

It could be because he was the source of the energy used to make the explosion; or maybe it was because the Kyuubi's chakra was still stabilizing when the implosion occurred, that some leaked out to form a shroud around the infant, protecting him for as long as the chakra was around; or maybe he just had some god or goddess looking out for him. The world may never know, or maybe the world doesn't care.

All that matters now, is that Naruto was rapidly approaching a bright light, the only source of light in the eternal blackness of the void, before disappearing from any and all sight.

Unknown Location; Unknown Time

A well-built man with short black hair and pinprick brown eyes, wearing a black turtleneck top under an unbuttoned white shirt doubled with a black blazer, suit trousers that crease at the ankles and black shoes to match as well as black gloves. He wears a grey trench coat over the top of his clothes to finish off his intimidating ensemble.

This man was named Lovro, a retired assassin who spends his days teaching his apprentices how to be an assassin, and how to constantly improve, even when they were not with him. His last apprentice had just left him not a week ago to go on her own and start building her reputation as a force to be reckoned with. Though, this left him with pretty much nothing to do with his time, except fight off the occasional hot-shot who wanted to try their hand at killing one of the best assassins of his time.

Tonight, on the other hand, Lovro was taking a stroll through the forest. While this was not something he usually did, he had seen a large, bright light emanating from deep within this forest, peaking his interest and causing him to investigate.

When he finally arrived at what looked like a crater the size of a car, the only thing that he could find was a small infant, wrapped tightly in an orange blanket, in the direct center of said crater.

Quickly looking around for a guardian or parent, Lovro was surprised to find no one.

As he turned back to the baby boy, the ex-assassin was able to spot quite a few black lines that looked to be permanently painted onto his skin.

"What are you doing out here, hmm?" Lovro wondered to himself before grabbing the infant and holding him close to his chest for safe-keeping.

"I don't suppose you will tell me your name, hmm?" Lovro asked with a small smile before spotting a name on the blanket he was wrapped in. "Naruto?"

Naruto finally opened his eyes to show the man his deep cerulean orbs that gazed straight into the man's soul.

"Hmm, Naruto it is then. Well, let's see what we can do about finding your parents or guardians, and if we can't find them, I guess you could stay with me a while."

End

Yo! First of all, I would like anyone who hasn't seen Assassination Classroom to go watch it, it's amazing. Secondly, I'm kind of disappointed in the lack of fanfics on the anime and the only decently sized one's I could find are NagisaxKarma. I can assure you right now that that will not be the case in this one, nor will there be and yaoi pairings. I'm not hating or anything, it just gets annoying after a while when all people want to do is homosexualize main characters just because they're close. (Seraph of the End is a perfect example). I might add in a few jokes, but that's it. Well, thank you all for reading this little A/N (if you even did read it. I'm looking at you Jerry). Please Review about what y'all would like to see in this story, such as pairings, powers, canon character's (Ex. gender-bent or something), and other such stuff. I will see you all in the next one, Seeya!
