Summary: He was a trained Shinobi, a killer and shadow. He can kill everyone without them even knowing when and where he would strike. He was one of the strongest Shinobi ever produced in the hidden village. And yet, he chooses another path. The question remains… what will he do in the future? Naruto shrugs with his shoulders and smiles. "I will not give up, that is my ninja way!"

Flashback/Memories of the past

Naruto was walking home when he sensed something in the distance. He narrowed his eyes and looked in the direction of the park where he had rescued someone. 'Is that a fallen angel?' thought Naruto.

Naruto disappeared from his current position and reappeared in front of his house. He went into the house briefly and put down the bag with the purchases. He then went straight out of his apartment and locked his door. He then disappeared again and reappeared in the park a short time later.

He hadn't even noticed until now. But besides the fallen angel, there was someone else here in the park. He looked to the side and could feel it very clearly. He was a trained shinobi, a trained assassin/killer. His senses were trained to the highest limit, and he could locate almost every living being at a certain distance.

Naruto looked at the fallen angel, which was injured and could hardly move. Naruto thought he saw that fallen angel somewhere before. He just didn't know where from. He tried to remember, but he just couldn't.

He narrowed his eyes as a magic circle appeared in front of the fallen angel. The aura that appeared in the magic circle was clearly that of a strong devil. 'I felt stronger auras before, but he is still stronger than the devils at the Kuoh Academy.' thought Naruto.

"Oh, my dear Raynare. Because of you, Asia Argento has now been reborn as a devil by the Sitri, and you have failed in your mission." the devil said to Raynare, who had suffered severe injuries from fighting Issei and the other members of the Sitri family.

"Fuck you!" said Raynare. She cursed that red dragon emperor! First, he managed to be reincarnated as a devil and although she let him go on the second meeting he still interfered in the ceremony where she wanted to extract the Twilight Healing from Asia Argento.

She even made it but was severely injured by Sona Sitri and her damn Queen and the Sacred Gear was taken from her in the process. It was a miracle that she was still alive. All other fallen angels were dead, only Raynare managed to escape.

She only got as far as this park and here suddenly a strong devil appeared, which was definitely stronger than herself. Damn it! She already had the Sacred Gear and with that she could finally ascend and get the recognition from the others.

Raynare was an attractive young woman with violet eyes having a slender body with large breasts. She had long silky black hair down to her hips and possessed two black feathered wings. She wore black, strap-like objects (resembling leather) around and under her breasts, a thong-like piece held around her hips by three thin straps, gloves that ran right up her arms with small lengths of chains hanging from them, shoulder guard -like objects on her shoulders with three large spikes sprouting from her right shoulder, and black thigh-high heel boots.

"Who are you?" Raynare's purple eyes bored into the devil's closed eyes. He was a gentle-looking, handsome young man with dark green hair. He wore expensive clothes with a white cloak with white fur.

"Oh, where are my manners? My name is Diodora Astaroth. I wanted to get Asia Argento, but she was taken from me by your action, and I will kill you because of it." Diodora Said with a smile.

Raynare grit her teeth as Diodora approached her. She barely had the strength to stand at all. Sona's last hit had been serious, and she'd taken a lot. Sona Sitri was very gifted with water magic and Raynare had taken a full broadside.

Diodora was now 2 meters in front of Raynare and just raised his hand. A green magic circle appeared in front of his hand, and he said "Die now you miserable bitch." His voice deepened and it was full of anger.

Raynare felt faint and she was about to fall over before she disappeared. A beam of pure magic came out of the green magic circle and just hit on the earth. Diodora's eyes widened as Raynare simply disappeared. She just disappeared mid-fall.

Naruto appeared a few meters in front of Diodora with Raynare over his shoulder. He didn't even know why he was helping Raynare. He could only explain it that way because he wanted information. There was no other possibility. He now knew again who the girl was.

That was the fallen angel, who attacked the human he saved in the park the other day. She wanted to kill him, because he had a potentially strong sacred gear and if he couldn't control this power, than he would be a danger for all fallen angels in the future.

He just couldn't make out where he knew her from. Maybe that's why he saved her. But that wasn't so important right now. First of all, he would have to take care of this devil in front of him. He had no idea who this Asia Argento was. But one thing was clear: the devil was quite a psychopath, and it would not be a pity for him.

Diodora looked at Naruto. He held Raynare slung over the other shoulder. He seemed inconspicuous, but Diodora knew it straight away. This man was not a normal human in front of him. Just the speed at which Naruto moved a second ago to save Raynare from his attack… that said enough about him.

"Only chance to leave, Diodora Astaroth." Naruto said.

Diodora held his stomach and smiled before he started laughing out loud. He couldn't believe it. A simple human really thought he could take on a High-Class Devil! Diodora calmed down and looked at Naruto with an amused look.

"Do you really think you have a chance? You are just a simple human! I am aware that you got some type of training, but you are still only a human! I'm Diodora Astaroth! I am the strongest devil of the new generation of satans." He held out one arm in front of him and a green magic circle appeared right in front of it. "I'll even make you an offer human. Now if you give me the fallen angel, I will just erase your memories and let you go."

Naruto didn't say anything and just stood there. 'He's strong, but even against him I don't have to use all my strength.' thought Naruto. As a trained shinobi/ninja, he got all the skills he needed to fight against the supernatural world. He was one of the strongest ninjas, which came out of his secret village. The secret village where he was raised and trained isn't common knowledge. After all, ninja was said to be only a saga from the past. No one thought that actual ninja still exists in the modern world. Even the supernatural world wasn't aware of the existence of ninja in the modern world.

"As you wish humanly, then just die with the bitch." Diodora said with a loud voice. A beam of magic shot out of the green magic circle, which raced straight towards Naruto.

Naruto just disappeared with Raynare and reappeared a meter away, dodging the magic ray in the process. 'Doton: Rock Spikes.' Naruto stomped once on the ground and the result was, that the ground cracked and after that massive rock spikes came out of the ground in a straight line, that headed towards Diodora. Diodora narrowed his eyes and spread his wings. He flew in the air and looked at the rock spikes, which destroyed everything in the way. Since they were in a special kind of barrier, the dmg would be undone, once the barrier was destroyed.

He looked at Naruto, who simply stood there with Raynare still slung over his shoulder. Out of nowhere appeared Naruto right behind Diodora and kicked him towards the ground. He hold a few kunai in his hand, which he through after Diodora.

Diodora twisted his body away and dodged the kunai. The attack missed him and then Diodora looked around. Naruto appeared on the ground a few seconds later, still with Raynare slung over his shoulder. He looked up at Diodora and just looked at him.

'He's almost... almost too fast. Who is this person?' thought Diodora. He couldn't follow Naruto's movements even though he was one of the strongest devils! How could that be? He didn't understand. He should have finished off Naruto with a simple magic ray!

He wanted to continue fighting, but a green magic circle appeared in front of his ear. He looked to his ear and narrowed his eyes. He looked to Naruto at the bottom "You are lucky, human. I must take my leave. Other matters are more important right now. I will come back at a later date and kill you and this fallen angel." He waved one time and then disappeared with a teleportation circle.

Naruto looked at Raynare, who was still slung over his shoulder, unconscious. 'Time to vanish, some devils are approaching this position.' thought Naruto. He sank into his own shadow with Raynare and simply vanished without leaving a trace. One Ninja Technique was the control of shadows. Naruto can travel through shadows or hide in shadows to gather information. He could also teleport to a nearby shadow and use it to hide. After Naruto vanished in his shadows, the barrier cracked and vanished. The dmg done by Naruto and Diodora was reverted, and the park looked like always.

"We haven't found Raynare anywhere, Buchō," Koneko said. Koneko Tōjō was a petite girl with white hair and gold eyes. The front of her hair had two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back had a short bob cut. She also wore a black cat-shaped hair clip on both sides of her hair. She wore the Kuoh Academy girls' school uniform, without the shoulder cape.

After last night's events, Sona had asked for assistance to find the last fallen angel as well. She escaped after turning Asia Argento into a devil, thus achieving the goal of saving Asia Argento.

Sona did not rule Kuoh alone but ruled the city alongside her rival Rias. Rias was a beautiful young woman with a voluptuous body, white skin and blue-green eyes. She had a very curvy figure with massive breasts. Many say that this woman was the number 1 beauty at the Kuoh Academy. She wore her normal attire, which consisted of a white long-sleeved, button-down shirt (short sleeves for spring/summer), with a black ribbon on her shirt collar worn under a black shoulder cape and a matching button-down corset, a magenta skirt with white accents, and brown dress shoes over white crew-length socks. This was the normal school uniform of the Kuoh Academy for females. Her name was Rias Gremory, sister of the current Satan Sirzechs Gremory or Sirzechs Lucifer.

The room was lit only by a few candles. Right in the middle of the room was a table with a candlestick on it, momentarily illuminating the room. Right and left was a black leather couch, where 4 people fit on it. Directly behind the table and further along the back wall of the room was a solid wood desk that had elegant carvings carved into the wood. Behind the desk was a single leather chair where Rias was currently sitting, who was talking to Koneko. There was another window in the room with curtains on it. There was even a functional shower in the right rear corner. Directly in the double doors, which led to the room, there were cupboards for books, glasses and other things on the right and left. A few pictures of landscapes or houses hang on the walls. which did not appear to be of that age. There were also some animals in the landscapes that shouldn't have existed at that time.

Rias nodded "Thanks you, Koneko." Rias said. She had mentored Koneko with this task because she was best at tracking down others, through her Nekoshō lineage. She had heightened senses and was better able to read the auras of others.

She actually wanted Issei Hyōdō as her servant, but her rival had been a bit faster and so she had lost him. She had been sure that with Issei's help and the right training for him, she could have gotten out of her situation. But that wasn't so important now, after all she now had to take care of the things that were triggered by the action of the fallen angels. Not only did her rival get another servant, but there were moves from her cousin in Tokyo. Her cousin lived in Tokyo and was in a similar situation to herself. She was also betrothed to someone by the Gremory clan. On top of that, the person was an asshole like Riser. She desperately needed more strength so she could force herself out of this situation if necessary.

She kept her eyes peeled for other potentially powerful Sacred Gear wielders but so far, she hadn't found anyone else. At least nobody of interest. "What are we going to do now, Buchō?" asked Koneko.

"We'll let Sona know and wait and see. I'm sure Raynare won't show up again." Rias said.

She got up and went to the window. She opened it and her hair blew a little through the resulting draft in the room. The sun was high in the sky, and she was thinking of a certain person. She was sure he would have handled the situation better. She gazed into the distance until something caught her attention. She could see a human in the corner of her eye. She looked at one of the many trees that were surrounding the building.

The old School building was a three-story building, with the third story serving as a clock-tower. It had been painted white with a black roof with vines creeping up to the second story. Around the old school building was a dense forest, with a path leading from the old school building back to the new one. In the old school building was the base of the Occult Research Club.

She could see a classmate sitting with his back against a tree reading a book. She wouldn't have noticed him at first if the sun wasn't shining on his golden blond hair. He sat there perfectly in the shade to hardly be seen.

Naruto had golden blond spiky hair, 6 whisker marks on his face and ocean blue eyes. He wore the Kuoh Academy boys' uniform, which consisted of a black blazer with white accents over a white, long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, matching black pants, and brown dress shoes.

He also had headphones in his ears and appeared to be listening to music. It was break time and so not all members of the club were in the club room. Some were elsewhere on the massive grounds of Kuoh Academy. Only later would Akeno and Yūto join them.

Like Rias, Naruto was a 3rd year high school student at Kuoh Academy. He just wasn't in the same class as Rias. She had spoken to him a few times before. He was polite but not too distant. He always had a smile on his face, just like now. He was a regular student enjoying his time at Kuoh Academy. There was nothing unusual about him other than his exotic looks. He had normal grades in every subject and normal hobbies.

He liked to help others when they had problems. She once had a suspicion that he would own a Sacred Gear, but it turned out to be wrong. There was no sign that he owned a Sacred Gear.

Naruto seemed to realize he was being watched and looked around. He looked at the old school building and saw Rias Gremory standing at the second-floor window looking down at him. Naruto waved a happy smile. Rias also smiled slightly and waved back.

She never really knew why, but his smile always made her feel better. She had toyed with the idea of getting to know him better. She would hate to do it, but there was a certain method she could use to extricate herself from her situation. But she would only want to use this method if it was no longer possible or if she had found a suitable partner.

Naruto looked back at his book and continued reading. Rias looked in his direction for a few more minutes and then Koneko spoke to her. "Buchō?" Koneko asked in her emotionless voice.

Rias looked at Koneko. "Everything OK? You look out the window all the time and don't react." Koneko said.

Rias raised both eyebrows and her eyes widened when she heard the ring, signaling the end of the break. She only watched Naruto for 2 minutes and not 15… right? She was sure that she wouldn't have looked at him for so long . She looked at Naruto again and saw him stand up and brush off his pants. He put his book in his bag and then walked towards the school building with a smile.

Rias glanced after him before turning to Koneko. "Koneko… we have a new target." Rias said. She was sure that Naruto wasn't a normal person. She had never just looked at him for 15 minutes in her life unless someone had tricked her perception. All she could think about was Naruto and at the same time her guess from back then came back to her. Maybe he did have Sacred Gear after all, or maybe he wasn't a normal person. She would definitely find out. She smiled slightly at the thought of finding someone potentially strong after all. If he had Sacred Gear that could affect someone's perception, that would be a powerful ability.

Naruto watched his clone as he walked towards the school building and then he looked to the window where Rias Gremory could be seen briefly before she closed the window again. He couldn't be seen, although he was in the shade of the same tree as his clone. He was just using his shadow technique, which allowed him to merge with shadows. He was currently hiding in the shade of the tree.

Having heard everything, he needed to hear; he was done here. The shadow of the tree seemed to move briefly. You could see for a brief moment that a small part of the shadow broke away from the shadow of the tree and shot across the ground and just disappeared.

In a hallway of the school building, Naruto emerged from the shadows and waited for his clone to come to him. His clone sank into its own shadow and after that the shadow became part of Naruto's shadow.

Naruto could create shadow clones from his own shadows. This was the third ability he could use through his control of shadows. He walked and made his way to the classroom.

'It looks like I'll have to pay more attention to my actions in the near future.' thought Naruto. He smiled slightly at the thought of having some more action in his life. He left his village on his own because he didn't want to just kill others indiscriminately for no reason. He was trained as a ninja and he already had enough blood on his hands, but one day it was too much for him and he left the village.

He left his village 4 years ago and meanwhile he missed the action a bit. He was not wanted or persecuted by either of his parents. But he was cursed, which prevented him from revealing anything about the village. Should he try, he would die outright from this curse. This was his father's condition for Naruto to leave the village.

Whatever the future, Naruto would remain true to his principles and go his own way. He would never give up because that was his ninja way.

Today was Saturday so Naruto could do whatever he wanted. He wondered how he would spend his time today. He'd already completed his training for the day, which meant he could head to the mall again. Naruto was currently sitting in his living room, which had a large couch, a small table in front of it, a closet, a TV on the wall and another dining table. He was currently sitting on his big couch and reading the book, which he also read yesterday during the break.

As a shinobi, not only did you have to train a lot, but you also had to learn. Information was even more important than one's own skills. Only with the right information could a ninja carry out the assassination perfectly without being noticed. He had read and learned from so many books that he couldn't even count anymore. There were a lot of books and through all the reading he found a hobby which he still enjoys doing to this day.

He closed the book and stood up. He was currently wearing a long-sleeved white shirt, gray pants and gray shoes. He still had his ninja gear, of course. But he hadn't worn these for years. Should he need weapons, he could simply summon them from a pocket dimension . He was able to store objects in another dimension through a certain ninja technique and also bring them up again. He mostly used this technique to summon his weapons mid-fight. Be it kunai, shuriken, swords or senbon. Of course, there were other things in the pocket dimensions, but that wasn't that important.

The book in his hand just disappeared as a strange seal appeared on Naruto's palm. After the book disappeared in a cloud of smoke, the seal also disappeared. He stretched once and set off. He wanted to get out of the city and into nature again.

It had been a few days since he was out in nature out of town. He liked to take care of nature by looking for the right thing there. He removed garbage, took care of the plants and other things. For example, last time he helped a fox that was injured by a hunter. Naruto had knocked out the hunter and then helped the fox. Luckily the fox was not shot. Hunting in the forest was actually forbidden because the forest was part of the nature reserve. That's why Naruto had no problem knocking out the hunter and dumping him outside the forest. He was still watching the hunter and was satisfied when the hunter disappeared.

Naruto could clearly hear the hunter talking to himself. He really thought that the evil spirits of the forest knocked him out and that was just a warning. Naruto was fine with that, and the problem was solved.

Naruto walked around town, letting his senses guide him. He thought of nothing in particular and enjoyed the warm rays of the sun. After a few minutes, a girl almost bumped into him. Naruto stopped in time and the girl got a little startled.

"Hey! Watch out!" said the girl. Naruto bowed once and said "I'm sorry for the inconvenience." He then just walked past the girl and ignored her.

"H-hey, wait!" said the girl. Naruto stopped and looked over his shoulder. "I'm sorry, okay? I wasn't looking where I was walking." the girl said as she crossed her arms under her breasts and looked away in defeat.

"Apology accepted. Have a nice day." Naruto said. He looked ahead again and continued towards his goal. 'It turns out the girl was the kind who hated to admit her own faults and when she did, she always came across as funny. What did everyone call it... I think it was Tsundere.' thought Naruto. He shrugged and smiled carefreely.

'Anyway, it's not that important. I'm looking forward to seeing the animals again.' thought Naruto. He would go later to the mall, when he was in nature a bit.

(A/N I hope you all enjoyed the first chapter of Irregular Shinobi. I wish you all the best. Stay strong all you of you out there!)

Name: Naruto Uzumaki

Age: 18

Height: 180cm

Race: Human

Information: Naruto Uzumaki was born in the hidden ninja village and was trained to be a strong shinobi like many before him. During his early days, it became clear very fast that he was a natural in the ninja arts. He learned extremely fast and got ahead of others his age. He was hailed as a born prodigy. At the age of 12 he finished his training and already got sent on missions. He infiltrated other countries, assassinated targets and did other things which he was commanded to do.

Abilities:

Physical Progress: As a Shinobi, Naruto was stronger, faster and more durable than a normal human. He has more endurance than a normal human and many more feats as a shinobi. He can compete with supernatural beings, which normally were stronger than normal humans. He can move at high speed without a problem, which is mostly too fast for even supernatural beings. He can deal great damage with just a single blow from his body. He can punch a hole in a brick wall without damaging his own skin. Naruto also was a weapon master. (Shuriken, Kunai, Senbon, Smoke/Exploding Bombs and Swords)

He was especially good with a sword, and everyone hailed him as Golden Steel storm, because his sword strikes were so fast that many couldn't even see them. He even learned the secret sword style from his family. The Uzumaki Clan was known for a few things. A Uzumaki has a stronger body than others. A Uzumaki lives longer and the Uzumaki clan was also known as clan of longevity. They were also sword masters, which created a very special sword style, which was superior to every other sword style in the world.

Ninja Techniques:

As a ninja, Naruto leaned many techniques, which every ninja learned. May it be to hide somewhere or to fight. Ninja techniques where very special and rare.

List of Techniques:

- Hide in Shadow Technique. (A technique to hide in a shadow and to travel inside the shadow. He can hide from enemies or from targets and spy on someone like this. He can also teleport himself to a shadow to hide in it.)

- Substitution Technique (He can switch places with an object. He mostly uses this technique to fool others or to escape a dangerous situation. This is a high-speed movement technique, where Naruto uses a smoke bomb and his high speed to switch the place with an object.)

- Illusion Technique (Naruto can create Illusions to fool his target. He uses this technique to change someone's deception from the situation. Just like the time where he let Rias thought she looked at Naruto only for 2 Minutes, but in realty 15 minutes had passed already. He can use a typical illusion to disguise himself as someone else. He could make the target think, that Naruto is a friend or a family member.)

- Sealing Technique (With his technique, Naruto can create special seals to perform different tasks. He mainly uses this technique to create a pocket dimension, where he stored many different things like his weapons.)

- Ki Manipulation (He can use Ki to heal others, detect the auras from others and hide his own aura. He can also use Ki manipulation to paralyze the target.)

- Earth Manipulation (In every generation of Ninja were a few selected Ninja, who got special magic gems embedded in their body. Those magic gems allowed them to control a certain element. Naruto got the magic gem for earth manipulation. The name for earth manipulation is "Doton" which means Earth Style.)

-Shadow Clone Technique (He can create clones from his own shadow.)

Those are the knows techniques. (If anyone has other ideas for more techniques, then just write me a pm or a review.)
