NarutoxHighschool DxD fanfic.

This is taken 3-5 months before canon. Kuoh Academy hasn't start yet as they were still on there summer break, This is a small-harem story so if you don't like harems then I recommend you don't read this.

Inside a cave was a spiky blonde haired man. The man had 3 whisker marks on each cheek and had azure blue eyes that seemed to pierce right through people. His outfit consists of a headband on his right arm with a swirling leaf symbol, an orange shirt and black pants, and a white coat with red flames on the bottom. Behind the coat, it clearly says "The Seventh Hokage".

This was Naruto Uzumaki. The Seventh Hokage, The Hero of the Fourth Great Ninja War, and lastly The Yondaime Kami No Shinobi (4th God of Shinobi). A title he received when he saved the world from a madman who wielded the Tenseigan and with his achievements of mastering and creating jutsus. Although he looked quite young, he was, in fact, around 800 years old by now.

Currently, beads of sweat came down his forehead as he focused on a seal he was working on for the past 700 years. In the center of the seal was a sheath that was made of gold and was decorated with blue enamel.

This was one of Naruto's prize possessions. After the Fourth Great Shinobi War, no one in the shinobi world knew why but, Naruto cared a lot about that sheath. During his time as the Seventh Hokage, He encountered one of the very few last members of the Ototsuki clan who's objective was to recollect all chakra and turn it into a new Chakra fruit. The Ototsuki's name was Momoshiki. Unfortunately for the man, he would have actually succeeded in recreating the Chakra fruit if he hadn't touched one of Naruto's forbidden taboos. The Sheath.

When Momoshiki captured Naruto and tied him to the Shinju Tree, he saw something on Naruto's waist that interested him greatly. It was the sheath that Naruto carried with him. The sheath seemed to exhibit some sort of calm yet powerful energy that was quite different from chakra.

Thinking of it as another way to gain more strength, Momoshiki reached out to take the sheath from Naruto.

That was his mistake though.

The moment he touched the sheath, Naruto practically went crazy. He immediately went straight into Six Path's Sage Mode and unleashed barrages of all of his most destructive jutsus towards Momoshiki. The multiple Variants of his RasenShuriken, The Chidori which he learned from his best friend along with the Kirin and a weird golden energy that was formed into a sword came together striking Momoshiki down from where he stood completely destroying him.

Ever since that day, Naruto kept the sheath from within his seal right beside Kurama just in case anyone were to dare touch it or attempt to steal it from him.

Now, he was using it in attempts to create something that was never made before in this world.

A world traveling seal.

Suddenly, as beads of sweat dripped down his face, his eyes widened.

"Kurama now!" Naruto roared as he began pumping his chakra into the seal.

"Got it Naruto!" Kurama, his lifetime partner who's been with him since the day he was born. He obviously knew how important this was to Naruto right now. Naruto spent over 700 years working on this seal. Although it might not seem a lot to Kurama and the other Bijuu's, it was quite a lot for humans. If Naruto were to fail now, he would have to rework on this seal from scratch, not to mention find the rare materials that are scattered around the world to make the seal.

Pumping as much chakra as the two could, the seal suddenly began glowing a golden color as the sheath in the center began floating and started glowing a golden color as well. Before long, the sheath suddenly pointed towards outside the cave as it shot a huge glob of golden energy. Right when it was about to head outside of the cave, it suddenly stopped and showed a weird image. Something he was quite familiar with.

"We did it..." Naruto said with mixed emotions his face pale due to pumping in almost all of his chakra. Kurama was simply watching everything from inside of Naruto as he looked at that very familiar portal.

"Naruto... You know there were two portals and not just one. I'm not even sure who we even will find or if they are even alive after 700 years." This is what Kurama wanted to say to Naruto. In fact, he was even tempted to yet he couldn't. He couldn't destroy his hope. Not when he worked on this seal for 700 years.

"Kurama, you remembered what the old man said to us that day right? Those portals that we saw that day led to the same world yet different timelines. Maybe... Just maybe there is hope we could find them." Naruto said as he calmed his emotions that were running rampant.

"Even if the chances of meeting them are slim, I will do everything I can to help you find them Naruto." Kurama sighed before he promised Naruto. He was feeling really tired right now. Maybe it was because he pumped in almost all of his chakra into that seal or the fact he hadn't used this much chakra since the battle with that accursed Ototsuki. When Naruto heard this, he simply shook his head.

"Kurama, I can tell you're tired right now. Just take a rest. For something like this... It had to expend a lot of chakra. Even my reserves as an Uzumaki took at least 90% and even then the best I can power up the seal to was 30%. Not to mention me, who knows how much it took from you." Naruto felt the chakra left within his friend. It was currently fragile as if a touch could simply disperse the chakra. In this world, everyone who depletes all there chakra will most likely die no matter who they are. This was how it has always been. He obviously didn't want to lose one of the remaining people who happens to know about his life and is one of his precious friends.

When Kurama heard what Naruto said, he simply just gave a soft smile to Naruto before he closed his eyes falling asleep for god knows how long.

As Naruto felt Kurama slowly sleeping, he turned his head towards the sheath that was still pointed towards the portal. Quickly, he grabbed the sheath with a wave of his hand and placed it inside his seal right beside Kurama.

Turning his attention towards the portal again, he took a deep breathe as he slowly walked towards it, his blue eyes steeled itself with determination.

As he slowly entered the portal, an image of a beautiful blonde woman appeared in his mind. Her eyes were full of affection and her smile that was full of love as she gazed upon him before she looked down on something that was covered in a blanket in her arms.

"Please wait for me. I will find the both of you. The promise of 700 years ago will be fulfilled soon. Just wait..." Naruto whispered as he walked right into the portal causing it to close the moment he walked in.

From that moment, Naruto had disappeared from the Elemental Nations and the Shinobi World for good.

-In a city besides Kuoh Town-

A portal opened on top of a 7 story building.

"Hmmm... Quite impressive." A voice came from the portal. As he walked out, he continued staring at the scenery in front of him. By the time he was outside of the portal, the portal closed itself completely never to be seen from or heard about again.

"The technology advancement here is better than the Shinobi World. Yet..." His azure blue eyes narrowed down to the citizens who were walking.

"They have no chakra." This wasn't the first time he has seen this. There was only one time where he had seen something like this and that was her...

"Well, I guess searching around is the best for now." Naruto said as he formed a hand-seal.

"Shadow Clone Jutsu!" Like that, 10 other Naruto's poofed into existence. Yet, Naruto could only frown as small beads of sweat appeared on his forehead.

'My chakra reserves are at it's lowest right now. At this point, the only jutsu I can use is probably the Rasengan, 1 Flying Raijin, and the Transformation Jutsu.' Naruto thought to himself as he stared at his clones.

"Scatter. I want information about this world." Naruto ordered his clones as they all saluted at him with a nod.

"Yes, sir!" The 10 clones scattered across the city heading towards different directions in hopes of finding information about this world. When they were all gone, Naruto closed his eyes gathering Natural Energy from around it. The moment the Natural Energy entered him...

"KILL!"

Naruto's opened his eyes wide as he stopped what he was doing. Before long, a frown came across his face as he once again looked at the citizens below him.

"So, humans here have pissed off Mother Nature itself huh." Naruto mumbled. This made it a bit more difficult. At best, he could try to calm mother nature down but he didn't know where to start. He could send some shadow clones to help protect the forests, trees, and send clones to help with whatever that is happening. If the humans have polluted the water, then he would also have to try and stop them from doing that as well.

"Nyah~? So you are the one I sensed using Senjutsu." Suddenly, a voice appeared behind him. When Naruto turned around, he saw a beautiful black haired woman with hazel slitted eyes similar to that of a cat. She wore a black kimono that was red in the inside while also seeming a bit loose and had...two tails behind her?

"You wouldn't be the descendant of Matatabi that somehow crossed over here, would you?" Naruto stated as he blinked a few times.

"Who's Matatabi?" The woman asked her voice curious as to why he would think she would be a descendant of that person.

"Nevermind. Anyways, who are you? I sensed you earlier when I arrived. Out of everyone in this city, you are the only one with chakra. Not to mention that... You also obtained Senjutsu." Naruto narrowed his eyes at the woman before him. She blinked a few times before covering her hands and laughing.

"It seems you don't know who I am which is quite surprising. My name is Kuroka. I'm a Nekoshou and..." She suddenly dashed right in front of him before stopping as she smiled gazing at his eyes.

"I'm an SS-Class Stray Devil." Shocking Naruto, two wings popped out right behind her before disappearing.

'Devils... They actually exist here?' Naruto thought to himself shocked. Devils, Angels, and Gods. He did heard all those terms before. He knew better than to treat them as nothing real. The only real god he had ever met was only the Goddess Kaguya. Although, that person left quite a bad impression on him. He was only glad that she was dead with the help of Sasuke and that person. As for Angels, what are those? If there were such thing as angels, the world he lived in probably wouldn't bother to send children to war dying young. Devils? In his opinion, some of the Shinobi's from his time were devils as they committed all sort of sins and crimes.

"What... What are devils?" Naruto asked surprising Kuroka. How did he not know about devils? Isn't he apart of the supernaturals? Suddenly, her eyes widened as she immediately gotten into a defensive state.

"Are you an exorcist?" Kuroka said cautiously as she stared at him. The more she got close to him the more she felt another energy from inside of him. Something that was quite different than the Natural Energy and Chakra. It wasn't until he asked what devils were that she finally recognized the energy inside of him. The man held something no human could hold!

Holy Energy, the power that both Angels and Fallen Angels use! If he had a holy weapon, maybe she could understand, but one that was inside of him? He certainly didn't had a Sacred Gear so far from what she sensed so that only left one nearly impossible option.

This man had somehow gained the affinity to use Holy Energy just like the Angels of Heaven. A thing not a single person in mankind could do even dating back to the beginning of there time.

"No, I am not. I don't even know that is! Look, I was just secluded from the world until now. I don't even know the common sense of people who aren't apart of the supernatural not to mention anything that involves it." Naruto explained telling both truth and lies to her. No one should know who he is. At least, for now. Not until he finds someone he could trust here.

Kuroka still had some doubt in her eyes but slowly lowered her guard against him.

Before long, she began to tell him everything she could about this world. Telling him about many factions and legends. The Hindu Faction, Shinto Faction, The Greeks, Norse Mythology, The Three Factions, the great war, and all that. As she explained, he got more curious about the three factions she mentioned.

"What are the three factions?" Naruto asked curiously.

"The three factions compromise of 3 races each with there own unique abilities that once frightened the powerhouses of the world. They are one of the most famous beings to the humans considering their religion spread around the world fast. There are the Angels, beings who are a servant of the christian god basically. All of them are known to be quite kind-hearted yet can be easily be quite frightening depending on what sort of sin you committed. Then there are the Fallen Angels, beings who have fallen from heaven. They are angels who have committed sins. The most common known sin these angels have committed are Lust and Greed. Kuroka explained to him causing him to nod.

"What about the last faction?" Naruto asked. The moment he asked that her eyes were instantly filled with pain and grief before it disappeared as fast as it came. If Naruto wasn't a trained Shinobi, he probably wouldn't have even noticed those eyes that were filled with pain.

"They are the Devils. Led by The four Maou's Lucifer, Leviathan, Beelzebub, and Asmodeus. Because of the recent war, their numbers have diminished greatly and started using a system similar to chess to populate their own kind. Though to them, they are different factions, they are in fact one to the rest of the world. We simply just believe that they split into 3 different groups similar to how the Tepes Faction has two sides." She explained about the Evil Piece system to him and the devils before moving on to the rest of the Supernatural world. Naruto was honestly grateful towards her. Although he had clones searching around for information, the information she had given him would have taken him at least a month or two to gather.

It wasn't until long that after she was finished explaining that the two decided to walk through the city while talking to each other.

"So, what was it like being secluded from the rest of the world?" Kuroka asked curiously. The man seemed to be around 18 or 19. If he was secluded from the world at birth then wouldn't he not know how to interact with others? Yet, here he is, talking to her just fine.

"Honestly, it was boring. Being alone. Still, I had at least one person to talk to. A great friend of mine. At first, we hated each other. He wanted to get rid of me, and I wanted to get rid of him. Later on, though, we gradually began to put aside our differences and became the best of friends..." Naruto smiled softly as he reminisced in that memory when he and Kurama put aside their differences in the Fourth Great Shinobi War. That war, their friendship has been made. Yet, that war made him lose the person he loved and...

Before he continued further, suddenly, multiple memories flushed into his head causing him to stop walking. It seemed that the clones just finished scouting and one of them happened to get him a new identity and a house to live in.

"Mmmm? Why did you stop?" Kuroka asked him. All he did was simply flash her a smile.

"It seems I just got a new house to live in." Naruto said to her causing her to tilt her head making her look rather cute.

"I have this ability to form shadow clones. They can do all sort of tasks for me whether it be chores, scouting areas, and fighting. Once they disperse, I can take in anything they saw or any information they had." Naruto explained causing her eyes to widen. That was a really useful ability. If she had that ability, she could have probably not run as much as she did from the Devils and Exorcists that were chasing her.

"Kuroka, do you have a place to stay?" Naruto asked her as he just remembered she called herself an SS class Stray Devil. Something that sounded awfully similar to the Missing Nins and Bingo Books.

"No, I don't. You know that I have to always run or else I would be caught and then executed..." Kuroka said smiling bitterly. She hated running like this yet she did not have a choice. If she retaliated, the devils might just vent their frustrations on her sister. Although it was unlikely since she was taken in by the Gremory Family, that was still something that she did not want to risk. The two eventually decided to go on a roof of a building as they sat down on a bench together. Both enjoying the comfortable silence before Naruto broke it.

"Hmm... How about you stay with me?" Naruto said causing Kuroka's eyes to widen at what he just asked.

"Why?" Kuroka asked him with a confused look. She could not understand why he asked if she wanted to stay with him. She honestly didn't believe it was something like "love in first sight" as those things only happened in fictional stories and movies.

"You helped me out a lot by telling me everything you knew about this world and the Supernatural. Although it might seem to be not much to you, it was really important to me." Naruto simply said as he stared at the beautiful night sky. Although he could have gotten the information he asked of her through his clones, he doubts he would gain it all in a single day. It probably would've taken him 6 months and that was still pushing it.

"Are you sure you have no ulterior motives?" Kuroka stared at him cautiously. Although she had to admit she enjoyed spending time with him even though it was just for a few hours, there was still no guarantee if this was a trap set up by bounty hunters.

"Kuroka, I seriously have no ulterior motives. Although I am not sure what you experienced when those devils and bounty hunters chase after you, I can promise you I am not apart of those idiots who are after your head." Naruto said looking at her right in the eyes. Her eyes still had a hint of doubts but after a while, she simply nodded.

"Al...Alright. I'll believe you. Although, I probably won't be at the house most of the time due to other business." Kuroka said as she glanced away from him. Naruto simply just nodded not bothering to think that much about it. He took out a piece of paper as well as the brush he had for making seals back in that cave deep in the mountains and wrote the address on it before handing it to Kuroka.

"Here, this is the address. Feel free to drop by. The bed is already set for you so you can go ahead and sleep on it right now if you want. The furniture should be coming soon though so you'd have to get by with simple cereal until my clones go out to shop for groceries." Naruto explained as Kuroka just nodded a few times before placing it inside of her sash.

"Thank you." She said earnestly to him causing a small smile to come across his face. A smile that hadn't appeared for quite a while. How long was it? 200 years? The last time he smiled was only because of the Bijuu reuniting again and the temple that was built for each and every single one of them as a sign of respect. That was the day he finally let himself rest a bit knowing that humanity won't seal the remaining Bijuu's inside somebody. Then again, he was secluded in a cave and had no one but Kurama to talk to so maybe that was the reason why he didn't smile during those years in that cave.

"No problem. Remember that if you don't have a place to stay, I will always welcome you to my home." Naruto said with a smile on his face causing Kuroka's cheek to turn a bit pink. She closed her eyes enjoying the warm feeling she was getting in her heart before turning around, her back facing him.

"See you later." Kuroka said as she jumped from building to building before he couldn't see her anymore.

"See you later." Naruto whispered as he stood at his spot for a while before disappearing in a yellow flash.

-Kuoh Town-

In the corner of Kuoh Town, a woman was gazing at the beautiful stars in the moonlight sky in the backyard of the house beside hers. The woman had beautiful aqua eyes and long wavy black hair reaching to her waist and wore a pair of yellow pajamas.

As she was gazing at the stars, she suddenly felt an unknown energy pop up in the house. It felt similar to the one that was here before, so maybe the person just moved in? But how did he just suddenly appear in the house out of thin air? From his energy, he definitely wasn't one of those devils so maybe a Mage or a Magician?

As she was thinking this, the energy suddenly became moving closer and closer to her before she heard a door open from behind her.

"Ah, I wasn't expecting guests so soon." She heard the man said as he looked at her with a small smile on his face. Although she wouldn't show it, she had to admit the man was quite handsome with that smile of his. He had spiky blonde hair and azure blue eyes that seemed to look right through her. Along with that, he wore an orange outfit and a white coat that had red flames under it as well as a headband with a swirling leaf symbol on his right arm. The whiskers on his face seem to add a bit more charm to the man as well.

"I wasn't expecting a neighbor as well." The woman said as she turned her head back to the stars above her.

"A beautiful night isn't it." The man said walking over to her and sitting beside her.

"Yeah, it is." The woman said as she smiled slightly. The two gazed at the stars in silence before the man got up.

"Well, it was nice watching the stars with you. If you want, you can come here whenever you feel like it." The man said causing the woman's eyes to widen slightly as she blinked a few times before nodding her head.

"What's your name?" The woman asked the man as he gave her a smile.

"My name is Naruto Uzumaki." The man now known as Naruto told her his name. The woman repeated his name a few times before she stared at his azure blue eyes.

"My name is Rin Tohsaka. It's nice to you meet you Uzumaki-san." The woman now known as Rin said as she smiled beautifully as the moon shined on her.

NarutoxHighschool DxD Fanfic chapter 1 complete!

I've been making bleach crossovers so I want to dive in with Naruto. My next chapter for "A New Life" should be coming out really soon right now. So if you like that story, the next chapter should be coming in about a few days or a week!

Only 2-3 people won't be apart of the Naruto or Highschool DxD will be in this story. 1 of them is already known and it's Rin Tohsaka.

Naruto Harem: Rin Tohsaka (Fate/Stay Night), Kuroka, Rossweisse, Serafall, and Unknown (?).

Maybe Harem: Scathach?.

These are the only people who may or are in the harem. I will not add any more.

Naruto won't easily give anyone any information that he's from another world. Not until he fully trusts that person.

(Update: After a few messages and 2 reviews, I decided to remove Namikaze. Don't really know why people care about that so much. As for the 1st year thing, I messed up on that part and only noticed after reading another review. Those are the only changes I'll probably remove and add. So if that's done and over with I'll go write chapter 2 right now. It should be coming out in 2-4 days as I got like 1/5 of it done already. I won't gurantee that it'll come out in 2-4 days though as I got a friend coming over to hangout at my house and I got missing assignments I have to complete.)

(Update 2 8/18/2018: Fixed some mistakes here that I noticed. Although it was small mistakes, definitely needed to fix it so you cann enjoy the story without having to correct it in your mind. Thinking about getting a Beta Reader, if you are one, please contact me through pm.)
