Chapter 3: Shinobi vs Class 1-A...

A heavy silence reigned in the training area where a battle was about to take place, this being Class 1-A against the new guy of the class who was standing on the opposite side of the sides, as for All might he kept a good distance to watch the fight and the stop it if necessary.

"..." Several of the students were waiting for the moment to attack, but the doubt was there, they were still inexperienced when it came to fighting, some of them even never had a real battle in their lives, but others instead.

"Die!" Bakugo being propelled by the explosions of his hands flew at full speed against his opponent who was just standing waiting for the blow, using right hand the blond explosive gave a blow that caused an explosion that made several had to cover themselves, raising a big cloud of dust Katsuki rose among the rocks he raised with his explosion, "Don't hide you fucking coward!" with fury he looked for his enemy who was nowhere to be found.

"You're so loud..." Katsuki froze when he felt the shinobi's fist resting on his right cheek, this caused shock in the blond who didn't even see his opponent who was turning his back to him move, "Screaming like a psycho while attacking is not smart" he spoke in a calm way while he moved his fist away and crossed his arms, "You are a waste of time" after saying that he had to duck to dodge another explosion by the explosive teenager who only felt rage at his opponent's taunts.

"Shut up!" attacking again he was going to unleash a big explosion, what he didn't expect was that right arm was taken by the strong grip of the blond who was serious.

"Predictable..." before he gave his opponent time to think he tightened his grip on the arm of the explosive teenager and threw him to the ground, only to then lift his foot and step on Bakugo's right shoulder causing him to scream in pain at the cracking sound that was heard showing that his shoulder and part of the arm was broken, "I'm not done yet" taking Bakugo he lifted him up and without thinking he threw him at the feet of the students who were paralyzed before such brutality.

"Katsuki! Are you okay?" Kirishima was the first to reach his friend, his answer was the grunt of pain of the teenager who got up little by little, only to fall again by barely feeling his right arm, "Damn this is not a robe-" his scream ceased when before him appeared in a burst of speed the blond with the strange eye who was completely serious.

"Silence" without mercy he kicked the face of the redhead who managed to activate his Quick, but even with his resistance he flew backwards and knocked down Kaminari, "You are just brats" turning around he faced the tailed boy who wanted to attack him from above, but it was no problem for the shinobi to catch him by his left leg and slam him against Koji Koda, the boy with the power to talk to animals flew backwards with his partner to crash hard against the wall of the building knocking them both out.

Naruto was about to attack Mineta who did not stop shaking, but in his way appeared Shoji who launched himself to the attack with a rain of blows, but with his sharingan shining in a slight way the Uzumaki dodged each blow, "Stay still!" furious the giant made more arms emerged and that all went against his opponent who did not receive a single blow.

"This is... unbelievable" Momo watched in disbelief as did his teammates as the now eight-armed giant attacked with blurred goals that they couldn't see, however everything stopped when Koji froze as the shinobi ducked and connected a blow to the center of his stomach causing the giant to lose his breath.

"..." A great silence formed in the place as the masked giant remained standing, in front of him Naruto just took a step back pulling his fist away from the student's stomach and the student fell heavily to the ground.

Everyone had to be attentive when the blond with different eyes was going to attack again, however the Uzumaki was forced to stop when some loud sound slings hit him and his attention was focused on Kyoka who was using her suit to direct as much noise as possible against him, "Don't stand there watching, someone attack!" shouted the girl who was using all her possible strength to stop the blond, her teammates came back to reality at her shout and Shiori was the first to attack.

"..." stepping with force she made a layer of ice cover the right side of his body, grunting with force she made a mountain of ice of some wind meters appear suddenly and went straight against the shinobi who was covered by the mountain of ice, "It's done..." breathing heavily the girl had to fall to her knees, it was not easy to make so much ice appear suddenly, but it was necessary to stop that boy, that strength, that speed, he was a monster.

All the students could breathe a sigh of relief when they saw the figure of the shinobi inside the mountain of ice, "Wow they did well... I didn't expect that" everyone froze when they heard his voice again, among the students still on their feet fighting, behind all of them was Naruto who was folding his arms.

"Ahhh! get away!" panicking Mineta started to take dozens of spheres from his head and threw them against the shinobi, he looked curiously at the spheres that were thrown against him, but without trusting he didn't let any sphere touch him and ran against the dwarf who was already bleeding from his head, "help!" trying to run away he was grabbed by his cloak, lifting him up the shinobi looked at him with annoyance.

"Let him go!" in slow motion and using all the power he had available Lida ran at the shinobi, with blue fire coming from his ankles he threw a horizontal kick, however he was incredulous when instead of hitting the Uzumaki, he found himself hitting Aoyama, the French boy fell hard to the ground unable to fight from such a blow.

"Slow" Lida opened his eyes in disbelief when he heard the shinobi's voice behind him, this holding a paralyzed Mineta by his head he threw him into the air, only to kick him and send him against the speedster who upon catching the class dwarf lowered his guard and received a knee to the face that sent him tumbling into the distance.

The Uzumaki taking his sword out of the sheath took it from the blade of the sword and gave a blow with the handle to Toru who tried to attack him from behind, the invisible girl screamed at the blow on her head and was knocked down by a leg sweep of the Uzumaki who grabbed her leg, "Ahhhhhh!" being thrown also crashed against Kyoka who could not avoid being hit by her friend causing them both to fall.

Momo made a steel rod appear from her right arm and without hesitation she threw herself against the blond, the girl showed to have basic knowledge of the use of a Bo staff, giving a maneuver she tried to give her weapon against the head of the blond who only caught the object with his hands, swallowing dryly the black hair tried to retreat, but she could not since the shinobi's hand went on her face and was knocked down to be hit against the ground with abruptness.

Seeing the girl knocked down the Uzumaki raised the steel bar to continue attacking, but a long tongue got tangled in his wrist and curiously saw the frog girl trying to attract him with her tongue, smiling with mockery the shinobi turned around holding the tongue of the teenager to raise it a few meters to then crash it to the ground along with his other companions.

The shinobi had to raise an eyebrow when a strangely shaped shadow attacked him from the ground, jumping up he saw that the shadow was attached to a bird-headed student, falling back on the ground he dodged the shadow and ran against Tokoyami to give him a horizontal kick, hitting his opponent he saw that the spectral figure that was about to attack him disappeared when the bird boy fell unconscious from the kick he gave him.

"Hey leave them alone!" Rikido Sato took out of his suit an envelope of sugar and ingested it, curious the blond Uzumaki saw how the teenager had an increase in muscle mass and with a respectable speed for the shinobi ran against him, the teenager in yellow costume ran at full speed against his opponent who remained standing impassive, giving a low jump to give a dependent kick that was easily avoided by the blond, the blow hit the ground cracking him.

"..." with his impassive face the Uzumaki stepped back to avoid the rain of fast punches that Rikido was giving, but within seconds it was seen how this began to breathe in an agitated way and his speed decayed instantly, when the student was going to try to get more sugar he received a kick in his left arm sending him flying and crashing sharply against a rocks that were in the training area.

"Take this!" Naruto had to tear off his white sweatshirt when a corrosive acid fell on it, near him a furious Mina threw several times acid hoping to hit the boy who hurt her friends, but when he ran towards her he was knocked down by a kick in his stomach, losing his breath the pink-haired teenager fell to her knees.

"You fucking coward!" the Uzumaki watched with boredom as a large amount of tape wrapped around him, in front of him fell Sero who had his arms pointing at him, "You don't even restrain yourself against girls, what kind of men are you?" he asked angrily, earning only the mocking smile of the blond who just shook his head.

"You think the people you fight in the future will be gentlemen who won't hurt them, just because they are women, welcome to the real world stupid" with a spike of strength he broke his bonds and taking one of the straps he drew the student to him and grabbed him tightly by the neck, "You can be a child, woman or old man, that doesn't matter when it comes to fighting for your life and the lives of others" tightening his grip he made the boy squirm, until he finally released him, only to kick him and send him against the concrete wall.

Sighing the shinobi saw that only three people were left standing, Shiori, Midoriya and the Uraraka girl, placing his sword back in the sheath on his back he ran against the last three standing students, reaching the Todoroki he grabbed her by her suit and threw her into the air, she could barely try to land on her feet, only to be hit behind her neck by the Uzumaki's hand that left her knocked out.

"And for the grand finale..." smiling dangerously the shinobi ran against Ochaco who was paralyzed, when there were only a few meters left to reach her, she was pushed away by the green-haired teenager who took her in his arms to run and distance himself from the shinobi who frowned at this action.

"Shineeee! " what the Uzumaki did not see coming was that behind them was Bakugo who had his left arm extended and with the grenade on his wrist glowing brightly, with his teeth the blond pulled the safety of the engraving of his suit and an explosion of gigantic proportions hit the Uzumaki who could only cover himself, with his right arm hanging uselessly Katsuki fell to his knees to breathe in an agitated way, smiling he saw the large ditch left by his last attack, but that smile disappeared when at the end of the ditch of destruction was the Uzumaki standing with his arms slightly injured by the explosion that took him by surprise.

"..." smiling low the shinobi pulled his arms away and ran against the fatigued Bakugo who was struggling to stand up, reaching up he grabbed him by the head and smashed him to the ground knocking him out, sighing he left the boy's body. Standing up he throned his neck, it was fun, now there were only two more left.

"Smash!" the shinobi had to turn around and deflect a right by the green-haired teenager who surprisingly appeared behind him to attack him, deflecting the boy's arm that now glowed orange with red marks made it hit a nearby brick wall and the result surprised the Uzumaki who felt how the whole building shook and the thirty square meter concrete wall disappeared leaving nothing but a ditch of destruction.

"..." still surprised the blond saw that the boy was on the ground, but his legs and his arm with which he gave the blow were severely damaged, leaving his surprise aside he saw that the boy had a kind of enhancer that reminded him of the inner doors, "Interesting" he said to himself as he walked towards the last person standing.

Ochaco was scared, all her friends were defeated, and now he was coming for her, shaking uncontrollably she put herself in a clumsy fighting position that had no defense, seeing that she only had a few steps to go before she closed her eyes, "Hum?" confused she felt a weak blow on her forehead, opening her eyes she saw that the blond only hit her forehead weakly with the tips of his fingers, without further ado he moved away from her to walk to the exit.

Bringing his right hand to his forehead the blond lowered the right side of his sash to cover his sharingan, sighing he came to stand next to All might who had not moved since the battle began, "Let the brats be attended to, I want to collect my bet in a few hours" without further ado the shinobi without a scratch left the training area.

"..." dropping a bead of sweat down his forehead All might saw the whole class 1-A defeat, bringing his hand to his ear he activated his communicator, he had to alert the infirmary and some doctors.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

A few hours later in the audit room we see the Class 1-A gathered, all of them had some blows, some more severe than others, being these as Bakugo's right arm that was bandaged, as well as Midoriya who also had his right arm bandaged and apparently it was hard for him just standing up showing that his legs were not yet fully healed.

They were all upset and dejected by the beating they suffered at the hands of the new guy who was just a few steps away from them folding his arms, "So that's all you got?... I'm disappointed" the Uzumaki's words only made the students' anger increase more and more.

"It's not fair you're too strong!" the invisible teenager shouted angrily at the blond, "Besides you're crazy to peel like that! It wasn't supposed to be just practice!" shouted again the girl who had bandages around her head.

"She's right, you're a brute, someone could have gotten seriously hurt" said Mina Ashido who like the others only felt anger against the blond teenager who was not affected in the least by the students' shouts.

"So it's my fault?" asked with sarcasm the shinobi who continued with an impassive expression, "You are just brats playing at being heroes, you lack a lot of discipline and training to just use those powers, right now you are nothing more than insects that I could crush if I wanted to" each words made the students feel more and more belittled, instead others only felt fury.

"Shut up you fucking scum!" impulsively and mowed down by anger Katsuki ran at the Uzumaki, but it was all over in less than a blink of an eye and the students were taken away in disbelief when they saw the explosive boy on the ground under the grip of the shinobi who placed the short sword behind the explosive teenager's head.

"Let him go!" when Deku was about to try to save his friend he was stopped by a kunai that fell at his feet, the tension in the place was severe, some panicked students looked at All Might who was nearby looking at everything seriously.

"Bakugo right?" asked Naruto who held tightly the explosive boy who was giving him a stinging look, "You think you are the best of all, you attacked first, without a plan in mind, you tried to blow me to pieces with an explosion that would have also hit your partner, who if not for the Midoriya boy would have been hurt or even killed... Do you have so much anger and rage that you can't see your actions?" looking up he looked at the other teenagers in front of him, "Do you guys think this is just a game? The fight we had only proved one thing to me..."

"And what is it?" asked an icy tone Shiori who like her classmates were intimidated by that glowing red eye and the shinobi's attitude.

"That they are not ready for reality, do they think the people they face in the future will care if they are girls or boys? No, they will take you by the neck and rip your head off, that's the best thing that can happen to you, this is a dark world where you must make decisions" pressing the sword against Bakugo's head made several people tense, the Uzumaki looking at Midoriya caused him to stiffen, "Midoriya take the kunai from the ground..." doubtful the green haired man heeded the request and took the white weapon, "Now kill Uraraka or I will kill Bakugo".

A sepulchral silence surrounded the place, but before anyone could do or say anything All might made an appearance and took with force the man of the shinobi who looked at him with annoyance, "That's enough..." with a gravelly voice the hero number one separated the Uzumaki from the explosive teenager who little by little was getting up. The shinobi simply sheathed the sword in its sheath and looked at the teenagers who looked at him in fear, he just gave a choice of killing a friend or an innocent girl.

"You're a monster..." the whisper of Ochako was heard by everyone, the brown haired teenager stepped back when she earned the gaze of the blond who lazily went about placing his bandages around his forehead and right eye.

"I am a survivor, if you are willing to continue in this stupidity of being a hero, you should know that you will face decisions like this all the time, if you don't have the courage to make the right decision, someone else will and you won't like what will happen" without further ado the shinobi withdrew slowly from the place, as for the demos they just stayed where they were.

"The class ends for today, you can go..." before the words of the hero all the teenagers left the place, sighing All might rubbed his forehead with tiredness, there were cameras all over the room and training place where the fight took place, the capabilities that this boy had were amazing, but his ideals...

They were not what such a young boy should have.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Already passing the hours, in the lower areas of the city, in the apartments where the shinobi who was now sitting on his bed, with only the lower part of his clothes on, the teenager had taken off his sash to observe her for a moment, "Are you going to cry or just think about the beating you gave to the brats?" the comment of the Kitsune only made the shinobi sigh and let himself fall on the bed.

"They're just kids... it's better they enjoy this stage, all I did was give them a little taste of what awaits them" spoke aloud the shinobi who being alone didn't bother to speak in his sub conscious.

"You're sentimental... I'm going to sleep" saying that the Kitsume cut the mental connection leaving the blond alone sitting on his bed.

The Uzumaki just looked at nothingness as he picked up his sword and took a moment to look at it, how long had it been, since getting here, closing his eyes he let his sword fall on the bed next to him, dropping down he decided to fall asleep.

He had just broken one of his most important rules, now he was paying the price.

In the limits of the country of water and near the village of rain we see how the dark sky was momentarily illuminated by lightning produced by the storm that darkened the sky even more, among the dark landscape we can see several trees and large craters.

Near the place we see a blond-haired teenager who was badly injured, his left arm was hanging by severe fractures, he was only wearing dark pants showing his torso that had several dark bruises, one of his eyes was closed leaving only his Sharingan that shone with intensity.

The teenager breathed heavily as he used his right hand to pull out a scroll from his back bag, opening the scroll with his teeth he let it fall causing it to get wet from the heavy rain, exhausted the teenager used his blood stained fingers to write on the scroll, after a few seconds he took the scroll and closed it.

Forming hand seals with his only available arm he made a raven appear in an explosion of smoke, "Take it to him... now" obeying the order the raven took the parchment with his legs and flew away, looking at the sky the blond saw how his invocation was lost in the rain, falling against the tree where he was leaning he closed his eyes.

"Tired?" the teenager instantly jumped and avoided an invisible force that destroyed the tree and left a crater in the area, landing in the distance the teenager saw a dark silhouette with a dark cloak with red clouds, "You have earned my respect, not many can fight against a God" between the trees came out the person who attacked, was a grown man with orange hair and with perforations in his face being these small cylinders of dark steel, his eyes were silver with a pattern of yeses rings surrounding the pupil.

"If there is a God... that wouldn't be you Pain" tired the blond fell to his knees and looked at his attacker who showed nothing but disinterest, "So now you're going to kill me huh? So many years of friendship and service ... What a bad friend you are" the words loaded with mockery of the Shinobi only made the Rinnegan user raise his right hand and point at him, at this the teenager swallowed dryly and put himself in a defensive position.

"I was always surprised by your sense of humor, it was a pleasure Uzumaki Naruto" with a glint in his eyes he made an invisible force appear out of nowhere and erased over 400 meters of forest next to the blond Shinobi that was lost among the gravitational slingshot that sent him flying, lowering his hand the orange haired man turned around and walked at a slow pace back to the rain village.

In the distance between the fallen trees we see a motionless Naruto under the trunks that were crushing him, "How weak..." a female voice made the Uzumaki open his eyes and looked at the female silhouette of the nine tailed biju sitting on the trunk above him, "You did well though... nah who am I kidding, they made you shit, come on get up, I don't plan to have to reform in 120 years for your death" with those words the redhead raised a finger of her right hand and touched the blond's chest that was gradually surrounded by a bubbling layer of contaminated red chakra that was healing his wounds in a fast way.

"Ahg" grunting the teenager lifted the trunk that crushed him, already free he stood up to then walk with a limp, all while being followed by the smiling redhead who enjoyed seeing her jailer in such a deplorable state, even if she had healed his wounds, she only did it to prevent him from dying, the fractures and other damages continued to make every step a torment.

"I was expecting at least a thank you, but seeing you in this state, it's enough" the red-eyed redhead watched as her Jinchuriki kept walking to a random direction, "I don't understand, why you get up, you have nothing, you have no home, you have no friends, your family turned their back on you and your own people are looking for your head... you're alone" each word made the Uzumaki's gaze become more somber, walking briskly the nine tailed fox remained in front of the Uzumaki, "Just open the seal and I assure you that you will die quickly and you will see again your loved ones, your friends, your father and your sensei..." before she could continue speaking she was pierced like a ghost by the Shinobi who just kept walking.

"Dream on" with tiredness the blond continued walking under the rain, looking around he saw that he was already out of the limits of the rain village, arriving at a green meadow he saw that the rain gradually stopped, sighing he continued walking, only to fall down a sinkhole that opened under his feet.

Falling abruptly he saw that he ended up in a cave under the ground, looking up he saw the hole where he fell, frowning he stood up to see that in front of him was something strange, were two pillars of rocks that were vertically and parallel to each other, the stone had some strange engravings that were in a dialect that he did not understand.

"This..." the ethereal form of the Kyubi appeared next to his Jinchuriki and instantly recognized the engravings that were on the rock, moving closer he ran his hands along the rock pillar, "Jiji" frowning she saw the distinctive symbol of the rinnegan carved into the rock, "You should get out of here, this is not something humans should see" looking at his jailer he saw that the jailer only looked at the large pillars.

"..." raising an eyebrow at what the redhead said the Shinobi touched the pillar and was surprised when some grooves began to form, before he knew it the two pillars formed a glowing door that illuminated the entire cave, before he could retreat the blond was mowed down by the brightness and felt a tug that took him to the front.

Opening his eyes Naruto saw that he was on the bed of his apartment, grunting he rubbed his forehead with frustration, standing up he looked at the window of the room that showed how the sun slowly emerged from the horizon that gave beginning to a new day, sighing the Uzumaki went to prepare to go to the U.A, another day began.
