A/n- lets me make this clear, this story is going to focus mainly on Naruto and he is going to have some of Issei harem in his. If you don't like it because it's not original, then how can you watch a movie because some movies are copies of another one in some way.

and don't be a pussy by flamming me or other authors as guests.

Chapter one: The Supreme King's Awakening

"It was a lovely morning in the town of Kuoh, the streets could be seen full of people who are trying to make their way to their jobs or in the case of one blond hair male with whisker marks on his cheeks, who is barely trying to make his way to another boring day at the famous high school of Kuoh town. Kuoh Academy, this school used to be an all-girl school until three years ago when it was announced that Kuoh academy was turning coed. The blond teen wanted to skip another week of school but to his misfortune, he had to go or he would get after school detention for a week and a nice boring pep talk of why he should come to school by the student council president, who is very strict when it comes to school and that would be so troublesome for him.

'It has been two years since I came to this world and there hasn't been any sign of my chakra or Kurama and the other Bijuu,' thought the blond in his way to Kuoh Academy. The name of the blond male with whiskers was Naruto Uzumaki and he came to this world after he had been sucked into a black hole when he defeated Kaguya Ōtsutsuki.

-Flashback two years ago-

A 16-year-old Naruto had been fighting against Kaguya Ōtsutsuki. He had been in a battle with her for three days nonstop with the power that Hagoromo Ōtsutsuki had granted him after he had died from getting his bijuu extracted from him. The sage appeared inside his mindscape and granted him the Yang side of his power.

Right now Naruto was in his six paths chakra mode. "Damn it," said Naruto as he trying to think of something to seal her away and suddenly an idea popped in his head and he immediately started to gather chakra in his right hand to make his final attack on Kaguya.

He had finally finished gathering his Chakra and said, "Senpō: Jiton: Rasenshuriken" and threw it at her, hitting her and immobilizing her. He dashed towards her and touched her breast by accident, making her blush crimson. She felt that her chakra was starting to deplete so in one desperate move, she created a truth-Seeking orb that was big enough to destroy the dimension they were fighting in. She motioned it to come down on him to at least take-out Naruto but in the process, he released Kurama and the other Bijuu to help him out to take out the truth-seeking orb that was coming their way. All the Bijuu throw their Bijuudama at the orb and Naruto created several Rasenshuriken to at least do some damage. In the end, there was a collision of power that disrupted the time and space and created a black hole that started to suck everything in.

Naruto opened his eyes and saw that he was in some kind of void and he looked around to see if Kaguya was with him but he didn't see her so he assumed that she was sealed away but in reality, Kaguya was in somewhere else. she opened her white eyes and saw that she was in some kind of room but couldn't make anything out because the room was dark. she heard a growl coming from the right, so she turned to see what it was and what she saw was a giant saber tooth tiger with golden lines

"Well what do we have here?" said the saber tooth tiger

"Who are you?" asked Kaguya

"It's impolite to demand my name before introducing yourself." said the saber tooth tiger

"I'm Kaguya Ōtsutsuki and who may you be and where am I?" asked Kaguya

"Well Kaguya, I'm Rayleigh, the supreme king, and you're inside my host with me." said the supreme king

"Your host?" said Kaguya

"Yes indeed, I can see that the evil energy that was controlling you is gone." said Rayleigh

"Yes, I feel like myself again," said Kaguya

"My host was the one who freed you from that evil energy in you and in the process you were sucked into his body." said Rayleigh

"Sucked in! How?" asked Kaguya

"Come, follow me, I will show you what happened and who is my host." said Rayleigh getting up and walking to the darkness with Kaguya right behind him

-Flashback end-

Naruto had arrived in Kuoh academy and he was walking through the front gate and rumors could be heard coming from the students around Naruto.

"Why is he here?"

"It doesn't matter if he comes to school, he still a delinquent"

"The yakuza boy is here"

"Naruto ignored them because he was used to the rumor and it isn't easy when you're a blond male with cerulean blue eyes and has an appearance of a gangster. He was walking through the hallway to get to his classroom and in the way, He saw a crowd surrounding the famous 'Onee-Samas' of Kuoh. The famous 'Onee-Samas' of Kuoh were Rias Gremory, a buxom red-haired beauty with large breasts and a nice bubble butt, and Akeno Himejima, a young woman with long black hair, big breast and a nice rear. He passed by the crowd ignoring them and made it to this classroom. He went and sat down on the desk that was at the very back of the classroom and next to the window. He placed his bag down and looked out the window ignoring the whispers around him and when the teacher came in the classroom, that was his cue to sleep

"Naruto napped through the entire class and lunch had come. He woke up and went to the cafeteria, to buy a sandwich, and then went to the roof to eat. Once on the roof, Naruto unwrapped his sandwich and started eating while looking at the antics of the perverted trio, who were peeping through a hole that leads to the changing room of the Kendo club. you wonder how he knew they were peeping because they were giggling like his deceased sensei. Naruto chuckled as he saw the Kendo club girls coming out with wooden bokkens in hand and started to chase them all over the campus and while screaming and cursing them. Naruto fell to the ground holding his stomach from laughing at the antics of the trio of perverts, "Ero-Sennin would be proud of them" said Naruto getting up from the floor and wiping a tear away, 'Damn, how I wish you were here Ero-Sennin' thought Naruto with a sad smile. The bell rang announcing the end of the lunch break.

"Well, I guess I will skip the last two periods since they don't matter that much," said Naruto walking down the stairs of the roof to go to his classroom to grab his bag. he arrived in his classroom and grabbed his bag and left the classroom to go to the gymnasium. because there was a pool that the swimming team used to practice but since their practice starts after school, he decided to take a quick dip in the water. he came out of the boy's locker room and dived in. he spent the rest of the school day in the pool chilling without a care.

"The bell that signalizes the end of the school day had rung and Naruto had to get out of the pool because the swimming team was going to use it and if they saw him there, he would get in trouble for skipping. so he got out of it and headed to the boy's locker room and got changed, after that he went home to get something to eat and to get his apron to go to work because the bills didn't pay themselves.

"Naruto was awoken by a stray ray of light that had made his way through the blinds and impacted with his eye. He got up and went into the restroom to take a shower and get ready for another boring day of school. A few minutes later, he had come out of the restroom wearing a black blazer with an orange shirt underneath it and black pants with black sneakers. he grabbed his school bag and before he left, he grabbed a can of coke from the fridge and left for school.

"The walk to Kuoh was uneventful because Naruto had his headphones on the entire walk and was jamming to "Rocket Queen" by Guns N Roses. He had finally made it to the front gate and was being glared by everyone, so he ignored them and before he had arrived at the front gate he had turned up the volume to his music to not listen to them. He saw Issei Hyoudo, a member of the perverted trio, being chased and beaten by the Kendo club girls for something perverted he did. Naruto just kept walking to his classroom. once he arrived in his classroom, he went and sat in the same place he sat the previous day and went to sleep. the blond had woken up for lunch and he decided to skip school to go work. Right now Naruto was making his way to the Dragon Claw ramen shop, the place he works, that was owned by an older man named Claus. The ramen shop didn't have many customers and he was wondering how the owner kept the place going because the highest number of customers they ever had was 50. He just shrugged it off and kept walking. Naruto had arrived in the ramen shop and he was making his way in through the back door to the lockers for the employees where they could put their stuff up and get changed for work. Naruto walked in and saw the owner of the shop.

"Hey old man, how you doing?" said Naruto greeting the old man with a smile.

"Ah Naruto, my boy you're here early, your shift starts in an hour," said the old man with a kind tone and a smile that reminded him of the third Hokage.

"Naruto walked to his locker and opened it and said, "I know old man, but I was bored at school so I decided to skip the rest of the day and come here to work and spend it with you," said Naruto placing his bag in the locker then closing it.

"How many time have I told you to stay in school the whole day and not just for a few classes?" said the old man/

"I know Jiji but my last two classes are too boring and besides I already know everything that they are teaching." said Naruto putting his apron on and going to the front of the shop to see if there were any customers ready to order. he took the order of some customers that had just walked into the shop. Naruto spent the rest of the day working and chatting with Claus.

-The front gate of Kuoh-

"Naruto was a few blocks away from the school gate and on the way he saw the perverted trio and a black-haired girl talking on the sidewalk. he just kept walking and when he passed the black-haired girl, he sensed some malicious intent coming off her. He stopped dead on his tracks and turned to look at the girl, who saw him looking at her so she smiled at him. Naruto turned around and kept walking to school. once he had arrived in the front gate, he stopped for a second to try and figure out why did he sensed some malicious intent coming off the girl but he shrugged it off and kept walking.

-Weekend-

The week had gone by very quickly for our blond hero and we could see him sitting on a bench and thinking about what he should do since he had the day off and the sun was starting to set. "Umm, what should I do now?" said Naruto trying to figure out what he should do and his answer came in the shape of a rumble that came from his stomach indicating that he was hungry. "I guess I should get something to eat and then head home and relax. Yeah, I think that sounds like a plan." said Naruto nodding in approval to his plans for the rest of the night. He got up from the bench and started to walk to the center of the park.

Naruto was walking to the center of the park when he saw Issei with the girl that he saw the other day. Both of them were standing by the fountain, talking to each other. when Naruto heard something that the black-haired girl said that made him go eye wide.

-with Issei-

Issei Hyoudo had been asked out by a girl named Yuuma Amano to be her boyfriend. Since Issei wanted a girlfriend badly, he accepted her offer to be her boyfriend. he introduced Yuuma to his friends to brag to them that he had a girlfriend and that there going to go on a date on Sunday. It was Sunday and the day that Issei had longed for was here, his date with Yuuma. they were going to meet up in front of the train station and Issei had arrived a couple of minutes early to make sure that he wasn't late. he saw a browned-hair girl hand out fliers and she approached him and handed him one. he grabbed it and looked it to see what it says: "Your wish will be granted"./

"Yeah right, if only that was true," said Issei pocketing the flier

"Issei, hey," said Yuuma walking up to Issei.

Issei turned around and greeted Yuuma, "oh cool you made it"

"Sorry to keep you waiting," said Yuuma apologizing for taking a bit too long

"Nah it's cool, I just glad that you made it." said Issei. After that Issei and Yuuma went around town to shop and later on to get some ice cream

-Later on-

Issei was having the best day of his life and right now he was walking in the park with Yuuma. she made a stop in front of the fountain and turned around to ask her date a question. "Issei would you do me a favor~." asked Yuuma with a sweet tone

Issei smiled and said, "Sure, what is it?" with a smile

"Would you die for me?" said Yuma with a different tone of voice

Issei was taken aback with the question his girlfriend asked, "Could you run that by me again, I think I'm hearing things" said Issei cleaning his ear with his pinky finger.

"I asked if you could die for me~," said Yuuma and suddenly a pair of black feathered wings appeared from her back and her clothes were shredded to pieces revealing a bikini-like outfit with gloves that ran right up her arm with chains hanging from them, shoulder guard-like on her shoulder with three large spikes sprouting from her right shoulder, and black thigh-high heel boots. She made some kind of spear-like object on her hand and threw it at Issei, who was so shocked that he couldn't react, but a blond blur pushed him out of the way of the spear. Issei got over his shock and saw who was the one that saved him and it was the famous delinquent of Kuoh, who had fought the entire school and never lost a fight, Naruto Uzumaki.

"Senpai, what are you doing here?" asked Issei to the blond male that saved him from getting pierced by a spear-shaped object

"I was passing by on my way to get something to eat when I heard this weird chick say something that didn't make sense and then I ended up here, saving your ass from getting pierced by that spear," said Naruto not looking at Issei. 'What did I get myself into?' thought Naruto looking at the winged raven-haired girl in front of him who was letting off some kind of energy and it wasn't chakra.

'A human was able to move fast enough to move that pervert out of the way of my spear' thought Yuuma in disbelief at what she saw.

"Why are you doing this Yuuma?" asked Issei

"Isn't it obvious? It's because you are too dangerous to us" answered Yuma

'I don't get what the fuck is going on here but who are they? And how is this pervert dangerous to them?' thought Naruto trying to figure out what the raven-haired girl meant by 'us'.

"I don't fucking know what's going on between you two, but all I know is that I won't let you kill the perv" declared Naruto to Yuuma, who busted out laughing.

"You won't let me kill him but you are a mere human," said Yuma in a mocking tone and then she said, "Get serious boy".

"All right then square up thot and don't say that I didn't warn you," said Naruto cracking his knuckles then he disappeared in a flash and reappeared in front of Yuuma and delivered a jab to her face, knocking her back and sending her into a tree. 'Even though I don't have my chakra, my hits are still powerful. I just hate that I didn't start training when I got here' thought the blond

Issei was shocked at what he saw with his own eyes, he saw that the famous delinquent of Kuoh, the one who picked fights with gangs for fun and never lost a fight, had moved so fast that he couldn't see it and punched Yuma in the face hard enough to send her flying back. "Damn, I didn't know that he was this strong even though I heard that he never lost a fight but seeing it in person is a very different thing," said Issei.

Yuuma got up from the tree that she had been sent to, holding the right side of her face. 'Ouch, he sure does pack a punch that could even rival Dohnaseek, I need to finish this quickly or I'm going to suffer more of those hits' thought Yuma getting up and looking at Naruto. "Alright then let's put an end to this because I got things to do and a pervert to kill," said the raven-haired fallen angel making two spears on each hand. She threw one spear at Naruto which he managed to dodge it but didn't see the other one coming his way, he landed on his right foot and was about to jump away but at that moment he got a cramp on his right foot and it disrupted his jump and got impaled by the spear of light. he was sent back by the force of the spear, which sent him into a tree. He could see the raven-haired girl making her way to Issei.

Issei saw the blond delinquent get pierced by the spear of light and immediately his brain activated his fight or flight instinct. He chose to run and he did but he tripped a few steps later and started to crawl. he turned around to see Yuuma almost close to him, "Why Yuuma? Why?" said Issei crawling away from her

"Don't blame yourself Issei, it was his fault for giving you that power" said Yuma making her way towards Issei with a spear on hand ready to kill him. As she got closer to Issei she could see from the corner of her eye that Naruto was starting to lose consciousness. She smiled at the thought of getting rid him but at the same time it was a shame that someone so good looking like him was going to die, if they would have met in different circumstances, she would've had her way with him but she shook those thoughts away and focused on killing Issei. She got close to Issei and stepped on his leg to stop him and thrust the spear into Issei.

Meanwhile, Naruto was starting to lose his consciousness because he was bleeding out from the light spear that was on his stomach. 'Shit, am I about to die like this? not being able to save the life of that pervert or mine? Have I come this low in life? where I'm not able to save the life of one person or much less mine? No, I have to live,' thought the blond grabbing the light spear that was in his stomach and he tried to get it out, but it was embedded too deep in the tree and his strength was starting to leave his body. 'NO NO, I have to keep fighting,' thought the blond and at that moment he felt some kind of energy inside of him like it was calling to him. he didn't waste any time and embraced it because it was either die or find out what that energy was and if he could use it to save someone's life then he would take his chances.

"Yuuma was looking at Issei, who was barely holding to his life and smiled. She was about to fly away from the park when suddenly she felt a heavy presence coming from where the blond boy was. She started to walk towards the direction of the blond boy and as she was getting close to him. she was hit by a wave of intimidation that almost made her passed out. Yuuma tried to see if he was still alive but she couldn't see his face because his hair bangs were covering his face. She also noticed that his arms were covered with some kind of reddish-black substance (Luffy's gear 4 armament Haki) and he was holding the spear with both hands and suddenly the spear broke into pieces, setting the blond free. Yuuma was so surprised that she couldn't move because the blond boy had smashed the light spear into pieces. Naruto lifted his head to reveal that his eyes had changed from his cerulean blue eyes to pitch-black eyes and he had an emotionless face that scared her. The presence got heavier by a thousandfold that it froze Yuuma on the spot she was. She saw the blond making his way slowly towards her. He got in front of her and quickly grabbed her by the throat and lifted her up with her feet dangling in the air.

"Why did you attack the perv?" asked Naruto with a demonic tone that sent shivers down Yuma's spine

"I…was…task…to….kill….him," said Yuma barely managing to speak

"Who sent you to kill him?" asked Naruto squeezing her throat a bit

"I…can't…tell….you," said Yuma, and Naruto applied more force on her throat, "if…I…..tell…you….I'm….dead"

Naruto didn't see any deception in her words, so he let go of her and said, "If I see you or hear that you are killing more people, I'll come for you and kill you personally". Yuma just nodded and flew away. There was no sign of Yuuma and Naruto was starting to feel that his strength was starting to leave him once again. His eyes reverted back to their normal cerulean blue and he dropped to the ground and passed out right there. Shortly after a red magic circle appeared next to Issei and through it came Rias Gremory, she looked at Issei and knelt down next to him

"Koneko-chan was right to say that you had a sacred gear," said Rias then she pulled out eight red chess pieces that looked like pawns out of her skirt pocket. She placed the eight pieces of chess on Issei's chest and said, "I, Rias Gremory of the house of Gremory, grant you another chance to live and in exchange, you will serve and protect me" then the pieces started to glow and they went inside his body.

"Alright now that is done," said Rias about to leave but at that moment she saw Naruto on the ground, barely holding on to his life. Rias walked towards Naruto and knelt next to him and looked at him. "How are you still alive?" said Rias analyzing his injuries and she saw that there was some kind of black-reddish substance fading from his arm. "Could this be some kind of Sacred Gear?" said Rias pulling out a rook piece to see if it accepted him but nothing happened so she proceeded to do the same with the knight and bishop but nothing happened so she tried to combine the pieces. At first, she tried doing knight and rook and nothing happened so she did knight and bishop, rook and bishop but nothing happened. She was tired of trying different combinations and was about to leave when a piece that was different from the rest in color and shape fell out of her pocket and she remembered the piece that her big brother had given her as a present for her sixteenth birthday. She went on to try and the piece glowed and it sunk itself inside Naruto.

"Thank you Onii-sama," said Rias looking at Naruto's body.

-Next day-

Naruto opened his eyes and noticed that he was in his room and naked. he sat up and instantly a massive headache came, "Damn, what the hell happened yesterday?" said naruto rubbing his temple, and at that moment everything that happened the night before came flashing in. he whizzed and immediately checked his stomach for any signs of a hole, but there was nothing, like the events of the night before were just a dream. 'The hell, was last night a dream? it felt too real to be just a dream' thought the blond and from the corner of his eye, he saw the sheets moving. he lifted the sheet up and saw that Rias Gremory was in his bed with him and in her birthday suit. Naruto placed the sheet down and thought, 'Nope, I must be hallucinating' and lifted the sheet once more and she was still there. he heard a groan that came from the girl that was lying next to him, she opened her eyes and smiled at him.

"Good morning." said Naruto calmly, not showing any emotion

"Good morning." said Rias sitting up and stretching, giving Naruto a perfect view of her breast

"What happened last night?" asked Naruto

"You were killed and I revived you." said Rias

"Um so it was real." said Naruto rubbing his chin

"Yes." said Rias

"You are not human from what I can sum then what are you?"

"I'm a devil and you are my servant now." said Rias smiling
