Hello there, DelTheAUO here!

I've read a lot of fanfics on this site, and have decided to try my hand at making my own. This one is a crossover with Honkai Impact 3rd, a game that I've come to enjoy recently. This might be the only Naruto X Honkai Impact Fanfic on this site, so I hope it's a decent one for you readers!

(Deep under Konoha – ROOT Base)

"Bring in the next subject", said a gruffy voice, as two ROOT agents, brought in an unconscious man, and carefully placed him on some restraints embedded into a wall and secured him in place. Another ROOT agent, brought a small container, which consisted of a palm sized, violet crystal that was radiating such a presence, that it had to be stored carefully inside a specialized container.

The agent put on some gloves lined with hundreds of layered chakra absorption seals, and carefully took out the crystal. Out of its container, the energy radiated even more, resulting in everyone within the base detecting it's presence. The only reason the Hokage was not alerted, was due to the seals lining the walls of the base, and the gloves, which contained the energy in close proximity.

"Beginning the test on subject XX422." Said the ROOT ANBU with an tone devoid of any and all emotion, as the crystal was slowly brought close to the man's chest, but even before anything could happen, the man's eyes suddenly shot open and he began screaming in agony, as his skin began to burn, and his blood vessels felt like they had lava pored into them. The water within him began to boil, and within a matter of seconds, he was a pile of ash. The whole time, the ROOT agents, and the owner of the mysterious voice did not react to the screams.

"A waste. He had some potential, but it wasn't enough. We need a more durable body…." said the voice, until a plan came to mind…

(A few days later)

Naruto Uzumaki was not having a great day.

(Flashback)

It was a fine morning to start off with. No broken window? Check. No signs of intruders in the middle of the night? Check. Supply of Instant Ramen for breakfast? Check. Looks like it was a pretty uneventful night, which was perfectly alright with him. It was all going so well, until he noticed the time… it was 8:30 AM.

'Damnit! I'm supposed to meet Jiji for my enrolment at the academy at 9! Gotta hurry now…' he though frantically as he quickly threw on his clothes, a simple white t-shirt, with an orange flame mark in the middle, and some blue shorts. He stared at the unopened cup of Instant Ramen while thinking quickly. He had to make the decision right now. With a heavy heart, he quickly put it back in it's respective shelf, and picked up an apple lying on a table nearby. No way he was going to go hungry on his first day at the academy.

All that was left was to put on his sandals and leave. With the apple in his mouth, he quickly locked the front door and left. In his hurry, he didn't have time to look at the various disturbing messages written outside his apartment, most of which, were in red paint, giving them a likeness of blood.

(Time skip)

He made it in time, having eaten the apple on the way, he saw the elderly Hokage standing in front of the academy building, who seemed to be engrossed in deep thought.

"Jiji!" he yelled and waved, grabbing the old man's attention and bringing him back from the realm of thought. The Hokage, having noticed the young boy of 8 running as fast as his tiny legs could, waved back at him. Finally, having reached his destination, the blond boy panted heavily, as he recovered the air that he had lost.

"Now, now. There was no need to hurry. I wouldn't have had a problem waiting for a few more minutes." said the old man as he patted the boy's back.

"Thanks Jiji, but I was really excited you know? Meeting new friends and finally beginning my first step to becoming Hokage!" he said, the excitement barely being contained in him.

"I see. Well, since you're here, might as well go in." Said the Hokage, as he led the soon-to-be academy student into the building…

(Flashback end)

What was supposed to be a fun day of making new friends and learning new things turned out to be one that he was completely unprepared for. The whispers and isolation from the students, the different treatment that he received from the teachers, the stares from the parents of his classmates as they came to pick up their children… all of this built up on top of each other.

Disappointed at how his first day at the academy went, he began to walk back to his apartment with his head hung low. Maybe some ramen at Ichiraku's would help him. They always knew how to make him feel better after all.

Not noticing where he was going, he bumped into a man, who, judging by the stumble in his step, was clearly drunk. "Oi, watch where you- It's the demon! Get it!" he said as he began to wave the broken bottle at the boy, causing him to start running away in fear, as a few other villagers began to chase him around the streets of Konoha.

After about an hour of chasing, he turned back and noticed that the crowd chasing him had become slightly larger than it had started off. He could feel his breathing getting heavier with every single step, and his legs burning with pain. He needed to rest soon, or else he would pass out. Noticing a hole in a nearby wall that was large enough for him to squeeze through, he did not hesitate in using that convenient means of escape.

On the other side of the wall, there was a completely clear alleyway, with no people in the nearby area. Releasing a deep sigh of relief, he sat down to regain his breath and to soothe his aching legs. As he recovered, he began to contemplate about what had happened. He was aware that people had some hostility towards him, but could not tell why. Before he could think any further, he was silently approached by a shadowy figure, that knocked him unconscious instantly. The shadowy figure crept back into the shadows, where it could not be seen. Once it had confirmed that the coast was clear, it disappeared into the shadows of the village and made its way to a secret location…

(Time skip)

When Naruto came to, he found himself on the floor of a cell. He was bound to the wall by a shackle, and had some weird collar around his neck that had numerous squiggles on it, that he could barely comprehend. He looked outside his cell and spotted an ANBU.

"Hey! Why am I in here? I haven't done anything wrong!" he yelled as loudly as his parched throat allowed him to, but he got no response. At this point he was too exhausted to say anything and sat in the corner of the room. He was too hungry and thirsty to think about anything other than how to satiate the pangs of hunger striking him. He weakly crawled to the bars of his cell. 'Jiji will come, he'll get me out of this.' he thought with hope.

"Please, can you at least give me some water, I might not last much longer…" he said in a very weak and desperate tone. The ANBU considered his options…he didn't want the next subject to die, or else his master would reprimand him severely. He sighed and took out a flask of water and gave it to the weakened boy, who guzzled it down as if it was the last flask of water in the world.

After drinking the water, he thanked the ANBU and went back to the corner, completely unaware of what was going to happen to him…

(Time Skip)

The next time he awoke, he found himself strapped to a wall with various locking mechanisms keeping him in place. In front of him were about 5 ROOT agents, along with a man, however the shadows prevented him from seeing the man's face. The lack of any nourishment to his body for who knows how long, had caused his head to hurt and prevented him from hearing or seeing things clearly.

"Impossible, he shouldn't be awake. Are you sure you sedated him properly?" said the gruffy voice of the man in the shadows with a very displeased tone.

"Yes Danzo-Sama. We administered the highest dosage that was below the lethal level to account for the corrosive effect of the Bijuu chakra. It seems that it was not sufficient. Should I prepare another dose?" said a ROOT agent.

"No, it's alright. Let him witness what he is going to undergo. If he survives, he will know who gave him his power." said the now named Danzo as he stepped out of the shadows. Revealing himself to the boy, who was still unable to see clearly.

"Boy," said Danzo with a forceful tone. "Remember this, the power that you are being granted is for the good of Konoha. You would do well to burn that into your memory.." He said and walked back to his original place in the shadows. "Begin the procedure on subject XX423." he ordered to a ROOT operative.

"Yes Danzo-sama" said the operative, as another one brought the container containing the crystal. He was about to bring it close to the whiskered boy's chest when he was suddenly ordered.

"Stop. Take it towards the seal. It would provide a better means of containment. Four of you, come here and take this seal. It will help in further containment of the energy. One of you, take this different seal. It will subdue the Kyuubi's chakra in case it begins to seep out." said Danzo, as the operatives took the seals and were prepared for any accidents.

Danzo nodded at the operative with the crystal. On confirmation, the crystal was brought closer to the seal. As the tip of the crystal touched the seal, a sudden reaction occurred, and the crystal completely slipped in. This caused the whiskered boy, who was trying to make sense of what was happening to him, fall into unconsciousness.

(Within the Seal)

The Kyuubi, the most powerful of the Nine Bijuu was afraid. Yes. It was truly afraid. It had been peacefully taking a nap, when it felt its energy being drained at a very high rate. It quickly woke up and found the source of his weakening being a strange purple crystal, which was radiating a powerful aura. The aura being radiated was unlike anything that it had felt before. Not even the Rikudo Sennin, the strongest being he's known, radiated this much energy.

The crystal began taking a humanoid shape, one that was neither male or female, and began draining even more Chakra from the Kyuubi. Not liking the current situation one bit, the Kyuubi swiped at the crystal-being, which evaded the attack.

The crystal-being, wanting more of the Kyuubi's Chakra, lunged at it, with a spear made out of energy and sparks around it, indicating the element of lightning. In the blink of an eye, the crystal-being dashed around the Kyuubi, making numerous slashes on its Chakra-body with multiple slashes, causing it to snarl in annoyance.

The Kyuubi began to charge a Bijuudama, fully intent on destroying the being that tried to steal its chakra, once and for all. The crystal being quickly jumped back, as the Kyuubi fired the Bijuudama, causing a massive explosion. As the dust died down, the crystal-being was unscathed, with a barrier of lightning extending around it from its outstretched palm.

The Kyuubi was astonished that its most powerful attack was blocked like that. Before it could do anything, the crystal-being appeared above the Bijuu, Lightning blade pointed downward. With blistering speed, it stabbed the blade deep into the Kyuubi. It began pumping more energy into the blade, causing a pillar of white light to erupt around them.

(At the same time)

Naruto was screaming, as he felt like his body was on fire, which it was. His skin started showing signs of burning, which healed quickly as small amounts of the Kyuubi's chakra began to seep through. Danzo sighed. XX423 was going to be the same as the others then…

…Or that was what he thought until the screaming abruptly stopped.

(Back in the seal)

The blinding light began to fade, showing what was left of the battle. The Kyuubi's chakra was scattered everywhere in puddles of slightly viscous, red chakra. The crystal-being was left unscathed after the attack. The Kyuubi's chakra, being sentient, looked for a way to escape from this new threat, and the only way to do so, was slip into its host's chakra system. Seeking the energy of the Kyuubi, the crystal-being dispersed into energy and began to integrate itself into its new host.

(Back in the outside world)

The screams stopped, as Naruto fell silent. All the ROOT Operatives and Danzo were surprised, as this was a completely new development, since normally, the screams stopped when the subject had turned into ash.

The ROOT agents, due to their training, were barely able to avoid an arc of lightning that shot out from Naruto's prone form. Another followed. Another after that. Eventually, his body was nearly covered in the electricity that the boy's body was radiating. After a few minutes, the boy opened his eyes. They were not his usual blue, but a bright shade of Magenta. The bursts of electricity became even more intense, causing the ROOT Operatives and Danzo to be extremely worried now. A highly dense bolt of blue-violet lightning shot out from him into the sky, piercing everything in between.

"Everyone fall back! Get as far away as possible!" The old war hawk ordered as all the ROOT members tried to escape the base as fast as they could, however, only a handful of them, including Danzo managed to survive the massive blast of white lightning that crashed down on the base, resulting in a massive hole in the ground.

It would take hours for the dust to clear, by then Hiruzen would have gathered a handful of his ANBU and gone to the site, only to find a massive hole in the ground, charred rubble and one Naruto Uzumaki in the middle of it all, with an eerie red glow on his back…

And that is the end of my first chapter! Reviews would be appreciated, since based on the feedback I get on this chapter, I will decide whether to continue this story or not. I will accept constructive criticism, not flames. This is my first fanfic, so I'm bound to make a few mistakes here and there.

In case I do continue though, there will not be any fixed schedule for updates. Life as a college student does have its downsides…

I will try to answer questions in the reviews to the best of my ability.

Thanks for reading this chapter!

DelTheAUO, Out.
