In the novel, Issei really did have those thoughts of doubts, he questioned that he was much more perverted than usual, before he started fawning over her again.

It is hard for the reader to notice because it is in Issei's POV and when things are written in 1st person POV, it is harder to know what is happening because you are limited to what they see and feel, like how Rias didn't notice the illusion.

Vt doesn't own Naruto or Highschool DxD.

''Destroy you? Oh no, destruction leaves something behind, some charred remains or bones. When I am finished, all that will be left of you are memories.''
-Naruto-

-Inside a clubhouse of Kuoh-

''For a mobster, you really didn't put up much of a fight.'' Naruto said, to the dead, fat guy that he was holding by the neck and then letting go and allowing the corpse to fall down to the ground lifelessly.

Though it never reached it, a millisecond before his body touched the ground, it disappeared in a white mist.

The place which was once a place filled with, dancers, women, gangsters and music was completely empty... All those who were previously having fun in the club were sent back home through a illusion, and those that worked in there under the mobster, all received the same fate as him.

''This is bound to attract Michael's attention...'' Naruto said to himself, glancing around the area.

Killing humans normally brought the attention of the supernatural world in general, Heaven's more so than others. But none of those people were killed... They were all erased, it was the common fate of those that lost their souls to the Harvester. Getting their souls stolen by devils was one thing, their names still existed on the book of life and could still be recovered and sent to wherever they belong in the afterlife, a privilege denied to all of his victims.

Names don't magically disappear from the book, that was something only a selected few could do; Great Red, Ophis, Hades, Naruto and previously Albion along with the Biblical God. Out of the four that remained with the ability, it was difficult to chose which was worse for Heaven and the church, all of them represented very bad omens.

Though while it seemed wicked and/or cruel, it was actually more merciful than sending them to hell.

''I wonder who they will send here to investigate, hopefully they send Griselda or maybe even Dulio, the guy sure knows his stuff.'' Naruto said to himself and then gave a mirthful laugh, Dulio was one of the people he actually liked spending some time with, and Griselda was overall fun to mess with on his opinion.

'I could probably make some use of this place, it would be a waste for such a large area to be left for the government...' He then thought, making a mental note do get the place into his name.

''I have spent enough time here, best I get going...'' He said, making way towards the door.

''I never thought of you as the type to go out of your way to destroy humans, Naruto.'' Said a feminine voice in a monotone way as Naruto got out of the club.

''Ouroboros...'' Naruto groaned, closing the door of the club behind him and turning towards the source of the voice, upon seeing 'her' he scoffed. ''And I never thought of you as a loli type, though I guess it is quite fitting.''

''You are mocking me.'' She said or asked her usual monotone voice, it was difficult to tell which.

''Did I stutter?'' Naruto asked, a large grin forming on his face, ''Those people were in the way of my ramen. You know the drill, it's hard to find decent cooks nowadays. Besides, it is not like they will be missed, I made sure to end them fast enough.''

Surprisingly, Ophis nodded. Good cooks were indeed hard to find. That was a struggle that she could relate to.

''What do you want, Ouroboros? I can hardly believe you came here just to see little ol' me.'' Naruto questioned, his eyes narrowing slightly at the humanoid dragon.

''I did... I wouldn't have to come if you simply accepted my invitation and didn't tear apart all of those I sent to recruit you.'' She replied, meeting his golden eyes with her own dull grey ones.

''Hmph, it was their fault, they didn't take no for an answer, so I devoured their souls. You know me, I thought you were sending them to me as snacks,'' Naruto shrugged, as if it were the simplest thing in the world, ''If you came here for that then you are wasting your time.'' he said, turning away from her and leaving the place

''I came here for a reason and you will listen to me,'' She said, appearing besides him and following him down the road, ''I require your assistance to remove Red from my home... He is loud, I cannot have peace with him in there.''

The way she spoke, almost made Naruto feel bad for her, like a Native that just had his lands confiscated from him by some company, ''I have no desire of joining this ragtag faction that you assembled for such a stupid reason. My answer still remains the same.''

''Why? I don't understand, why you satisfy yourself with so little... I know you been waiting for this, for someone with whom you can truly fight against, why let go the opportunity?''

''That is true... But I have no interest in fighting him. Unlike you, he actually does something useful, like keeping things where they belong. If you have'' Naruto replied, stopping and facing 'her' once more, ''If that is all you have to say, then leave before my patience starts running out.''

''You are as hard-headed as the day you appeared in the gap... You intrigue me.'' She stated, taking a step closer to him.

''Do I? Never thought of you as the type to feel anything.'' Naruto retorted, glancing to the side and spotting an ice-cream store and making his way towards it, Ophis right behind him.

''Yes... You do... Your contract with Red ended hundreds of years ago, yet you still go on with it. Why?'' She asked.

''I would like a large vanilla cone and a chocolate one with extra sprinkles.'' Naruto said to the man in the store, placing a couple of bills in the counter, completely ignoring Ophis words.

''You say something, Ophis?'' Naruto asked, turning towards her and leaning his back against the counter.

''Yes...'' A small twitch in her lips, ''Your contract with Red ended several centuries ago, why do you still follow it?''

''Hmm...'' Naruto closed his eyes in thought, he had heard 'her' the first time, but wanted to make her repeat herself, a small smile appearing on his face as he remembered the day that he made the contract.

He was dying, his last clash with his best friend had sent him to the gap and his body was quickly deteriorating when they appeared, drawn by his will to survive and his dreams. The infinite duo appeared before him, the Red Dragon ejected his soul from his body from his own flesh and Ophis power, created a new one.

Then they made a contract, Great Red's part was that he guarded the Earth for a thousand years, for he could not due to his duty in the gap. Ophis part was far easier as per say, the dragon at the time cared for nothing, not even the noise that the red one made, so her part was much more simple. Took him time to learn how to make them, especially more so given the time that he had arrived, but he had fulfilled the contract, for both.

''Here are your ice-creams sir, enjoy.'' Said the man, bringing Naruto out of his memories.

''Oh right,'' Naruto said, taking the two and handing the chocolate one to Ophis, ''Here, it is complicated, you wouldn't understand, emotions and things of the sort.''

''Okay...'' She replied quickly, taking a lick of the ice-cream. If it were about emotions then she really wouldn't understand anyway, she is self-conscious about that fact.

Sighing Naruto glanced around and found a small wooden bench and then sat on it, patting the spot next to him for Ophis to do the same, ''if you are going to appear like a child, I'm going to treat you like one,'' he said with a smirk.

On the street some people stared at the two, no doubt finding the pair to be quite 'exotic'. It was uncommon for somebody of Naruto's stature and appearance to walk around the city, he practically stood out like a sour thumb, given his height, lack of shirt and overall western appearance. Ophis wasn't that far behind in terms of appearance, while Naruto made most women and some men twist their necks, Ophis did the same for most men and a few women, gothic lolitas were hard to find.

Ophis didn't respond verbally but obeyed, preferring to silently enjoy her ice-cream.

''Out of respect of you, I will warn you now, those people of the Khaos Brigade will overthrow you.'' Naruto said, fixing his gaze onto the sky. 'She' was one of the few people he actually respected as somewhat of an equal, despite 'her' inexperience with any type of relationship, 'she' was still one of the two that had saved his life.

''Oh?'' 'She' muttered, this time actually sounding like a question.

''The devils that you had sent to recruit me previously, when I devour someone's soul, I link myself with it and can see what they have seen. I normally avoid doing so, but I had seen the past few months and years of them. They are going to overthrow you somehow, due to how low they were in the chain of command, they couldn't provide me with much information about that.'' Naruto said, his tone a bit more serious.

''They cannot hurt me...'' Ophis replied, taking another lick of her ice-cream.

''That is a bad way of thinking, keep letting your guard down and one day they will get through it.'' Naruto advised her.

''If that happens, you will help me...'' She replied, the corner of her tiny mouth twitching into a small, almost imperceptible smirk.

''Hmph, yeah right... Remember to keep your dogs on a leash, if they start to bring problems to the world, I will not hesitate in annihilating them.'' Naruto said ominously, getting up from the bench and disappearing from the spot.

Ophis vanishing not much after.

-Next day at Ichinose's

''Hey Jiji!'' Naruto greeted the old man, walking into the store.

It was still around ten in the morning and there weren't any customers yet.

''Naruto my boy! What good timing, could you do this old man a favor?'' Omer asked, putting on his apron.

''A favor? Sure, what can I do for ya, jiji?'' Naruto asked with a grin.

''Well... You see, Yui-chan here is feeling brave and wants to go out to buy some groceries, but Riho and I are kind of busy, so could you take her?'' The old man asked, gesturing to a short, young, black-haired girl around sixteen or seventeen with shades that was sitting in a small chair behind the counter.

After being mentioned, said girl got up from her chair trembling slightly, her legs and arms were thin and her skin very pale. She was facing the general direction that they were, but one could tell that she didn't know exactly where.

''Ah... Hello Naruto-san, jii-san and baa-san told me about you... It is nice to finally meet you.'' She said softly, slowly waving in the direction that she last heard his voice.

Naruto's eyes softened considerably upon seeing the frail girl, and a small smile appeared on his face, ''I hope good things,'' Naruto chuckled, ''It is nice to meet you as well.''

Omer took the girl's hand and slowly guided her from the counter to Naruto, ''You take good care of her, she's my only granddaughter. She already knows what we need.''

Yui nodded and stretched her right hand forward, and Naruto took it with his own right hand, ''Umm... Can I 'see' your face, Naruto-san?'' She asked, fumbling a bit with her words.

''Sure.'' Naruto replied shortly, and she hesitatingly brought her hands to his waist.

''Eep!'' She squeaked, not expecting his body to be so sturdy and warm, but not removing her hands from him. Travelling upwards, she noticed a few things; He didn't like using shirt, he was much taller than herself, he was very well built and lastly, his body was abnormally hot, as in fever type hot.

Passing by his chest and his magatama necklace, she eventually made it to his face, he had to lean a bit forward for her to reach it better, but she managed nonetheless.

''A line...?'' She mumbled to herself, caressing his cheek, ''Two... Three... Whiskers?'' She asked and then giggled to herself, it was a first, she didn't meet all that many people in her life, but she was sure that it wasn't something common.

Ahem.

Omer coughed into his hand, ''Still here, I'm old, not dead. Off you two go.'' He ushered the two away, Yui letting go of Naruto's face and once again taking his right hand into her own, her left hand going to the back of his elbow.(1)

''Bye Jii-san.'' Yui said softly.

''Cya, Jiji.'' Naruto waved him goodbye.

Whack.

''Itai~!'' Omer yelled, nursing his head.

''You old coot, couldn't you wait a little? You ruined their moment!'' Riho said, holding onto a wooden spoon, ''But look at them, they make quite the pair.'' She then said, pointing towards the two.

''I guess they do.'' He replied, ''Doesn't mean you had to hit that hard!''

''You deserved it.'' She retorted simply, going to the back of the kitchen.

The two did indeed make quite the pair, even for the onlookers on the street. Naruto was practically her opposite.

Their walk lasted for around an hour, the store was relatively close, but given her condition, their pace was very slow. On the way Yui asked Naruto several questions, such as his surname, age, why he didn't like to use shirts, etc.

The shopping list was small, only a handful of common things. Naruto suspected that it was only an excuse of the old man to get her for a walk, she did enjoy the sunlight.

By the time they were done, Naruto noticed something, her breath had sped up and her grip on his elbow had lessened, her legs were also shaking a bit more, but she continued to walk, her will power was something truly admirable.

Seeing her about to stumble, Naruto swooped her from her feet and picked her up bridal-style, earning him a squeak from the frail girl, who was clearly not expecting something so sudden.

''Ah... Naruto-san, please put me down I can go on my own...'' She said weakly, a small blush on her face, her own voice contradicting her words.

''Nope.'' Naruto answered simply. ''You can't, I can see that you are struggling. You trusted me to take you to the store, allow me to take you back home.''

''This is embarrassing...'' She mumbled, it was indeed very much embarrassing, everyone in the street was looking at them, some whispering things to each other, and she couldn't see anything. To her the feeling was like she had no ground and absolutely no control over where she was going.

''I know.'' Naruto replied cheekily, a grin on his face, he could hardly care what the watchers thought, to him they were ants.

''You're mean...'' She said, the blush on her cheeks increasing, even though she found the situation very strange and embarrassing, his body radiated a very pleasant and warm sensation, holding his hands was one thing, being held by him and having her body pressed against his chest was way different.

Arriving outside Ichinose's once more, Naruto slowly placed Yui back on to the ground and helped her steady her feet.

''Here we go miss, safe and sound. Wasn't so bad now, was it?'' Naruto asked her with a grin.

''It was... Okay...'' She mumbled, fumbling a bit with her shirt, Omer and Riho walking towards the two.

''Here are the stuff jiji,'' Naruto said to the old man, handing him a bag with with the groceries, ''I gotta get going now. Got some things to do.''

''Huh? Going already, Naruto? Don't you want to stay for some ramen?'' Riho asked, taking Yui's hand.

''Sorry, I really got to get going. It was fun though Yui-chan, we should probably go out again some day.'' Naruto said, turning around and waving them good bye.

''A date...'' Yui said to herself, her cheeks gaining some color.

Whack.

''Why weren't you more like him, ya old coot, you never carried me around anywhere.'' Riho said, smacking Omer behind his head.

''That's only because you were so hea- never mind...'' He corrected himself, not wanting to face the wooden spoon of doom once more. Then went back to the kitchen, grumbling something under his breath about young kids making him look bad.

''So~ Yui. You got to tell me about how it was.'' Riho said to the girl, a mischievous glint in her elderly eyes.

-Later at night, Streets of Kuoh-

It was now night time and we find our hero, Naruto, sitting in the fountain where Issei had first died, gazing into the night sky.

'Perhaps I am getting soft.' He thought, remembering the events that had happened earlier in that day. It was unusual for him to care about a simple human life just for caring, but regardless of the race, he would always recognize hard-workers.

It was as clear as the day for him that she was in pain and that her body was weak, and she was trying her best to hide it from the two.

Admirable.

Such a trait was difficult to find. People who cared about others to the point of masking their suffering with a smile weren't easy to come by, and they were the people that he could relate to the best.

Maybe for his past, or even their nobility, Naruto found himself actually getting attached to the family...

''You two should come out now, stealth isn't your thing.'' Naruto said, pushing away his thoughts about the 'Ichinose family' and shifting his golden gaze towards the light post.

For a few seconds nothing happened, it almost made him seem crazy, but true enough, after a few moments of waiting, a silhouette came out from behind it, followed by another one of the same height.

''I thought I had smelled a devil...'' Naruto said as the two silhouettes showed themselves to be Rias and Akeno. ''You two must be either very brave or very naive to come to me after learning who I am, I am betting on the former.''

His ice-cold tone and stare sent shivers down both of their spine. Akeno glanced at Rias uncertainly and the red-head took a step forward.

''What do you want, devils?'' Naruto asked harshly, his eyes narrowing into a semi-glare, no killing intent being used, but even then it was enough to make their hearts skip a beat.

''U-um, there is something that I want to know?'' Rias said nervously, she had spent days thinking about a speech, and it just flew out of her mind.

''Go on.''

''I want to know if you were the person of that night.'' Rias said firmly. ''Eleven years ago, in the underworld. I was returning with Enku from the park and we were ambushed by the Old Satan Faction. Enku was over-powered and I was knocked out, the last thing I remembered was seeing golden hair, much like yours. When I awoke, I overheard a conversation between Enku and my brother of how they were found torn apart.''

Akeno's eyes widened upon hearing it, the accident was a taboo and Rias had never told anybody about what happened.

''And if it was?'' Naruto asked, raising an eyebrow.

''I just wanted to know, ever since that day I started researching about you, the books said that you were a monster that killed everything in sight, but you spared my life, twice, why?'' She asked, a bit of emotion coming out of her voice.

''You came here to ask me why I had spared your lives?'' He asked her with a bit of amusement. ''I didn't kill you back then because I don't like killing children, and right now you are too small for me to even consider you my prey. Though if you wish to die that much, then I can fix that.''

Both Rias and Akeno found themselves taking a step back-wards once he got up from the fountain.

''What is the other reason that you came here for.'' Naruto asked, his tone once again serious.

''I-I have a proposal for you.'' Rias stuttered, trying to regain her composure.

''A proposal? And what would that be?'' Naruto asked in curiosity, she had guts, so he could at least hear her out.

''I want your help to stop an arranged marriage.''

''You got guts coming here to ask me that, how do you expect me to help you? Say if I were to accept it, what would you have to offer me?'' Naruto then asked, his tone filled with amusement.

''Join my peerage, my family owns a lot of lands and money, we have a lot of influence.'' She said, now with more confidence.

Much to her and Akeno's surprise, Naruto started to laugh, really hard, as if she had told him the funniest joke in history.

''Join your peerage? Child, you don't have enough pieces to even dream of reincarnating me. I have enough power to burn this world down into ashes and enough wealth to rebuild it in a new glory! Your family wealth and influence are of no interest to me... I cannot help you, even if I did get you out of it, that would mean that I am allying myself with a devil family. That fact alone would start a war... Your sells pitch is quite well though, you of the Gremory household have always been good at manipulation, your Gremory ancestor was the very first devil to notice that by treating their slaves well, the chances of rebellion would lower for as long as the servants remained in the illusion.'' Naruto said, walking in their direction.

Rias would clench her teeth in anger, but the fear in her heart stopped her from moving.

''You are quite smart, the way you manipulated Issei was very impressive, you used his desires against him like a real devil, Lucifer would have been proud of you if I hadn't killed him the war along with the other Maous.'' Naruto said, a book appearing in his right hand.

Stopping in front of her, he dropped the book on her feet, and it opened up to reveal itself blank, ''Train, practice and write everything you learn in this book. Once the pages are black with ink, get white ink and start over. You have potential, don't become a failure like your brother...''

And with those words said, he vanished, both Rias and Akeno falling to the ground right after, gasping for air.

-Later in the streets of Kuoh-

''I suck so much that I didn't even get a pact, all I ended up getting was a heated debate about Dragon Boy Z. What the hell was I thinking back there?'' Issei asked himself.

He was now getting out of the house of his first contractor, but in the end he failed to make a pact with the man.

''Huh!'' He muttered as a dose of killing intent struck him, making him turn around and face the other side of the street, where a soft sound of footsteps started coming from.

''Someones there, is it that guy? It feels familiar.'' He said out loud.

''What a surprise, you are not what I thought, but you are certainly the one I was sent to find. My name is Kalawarner and I have orders to destroy you.. This is truly unusual.'' Said the tall blue-haired woman, now identified as Kalawarner.

''Whats going on?!'' Issei asked, letting go of his bike.

''Why are you still alive?' The woman asked angrily, black wings sprouting from her back.

'A fallen angel?!' Issei thought, getting ready.

''She was supposed to have taken care of this already!'' Kalawarner hissed, creating a spear of light and tossing it at Issei, who jumped out of the way right in time.

''Is that the Gremory family crest?'' Kalawarner asked in surprise, seeing the symbol on Issei's hand when he ducked.

''Does this mean I am about to be killed again?'' Issei asked himself.

''So you are the one that Dohnaseek was stuck for a strain, my my isn't that interesting? The fact that you are a part of the Gremory household makes it all the more important that you are destroyed!'' She yelled, flying into the air and creating another spear of light on her right hand, then launching herself towards Issei.

'This bitch is actually going to kill me! NO! That power they said I have, I need to figure out how to use it!' He thought, remembering Rias's words about concentrating on the part of his body that he felt is the strongest and then remembering his time with his client and how he felt his left arm to be powerful. (2)

''FOCUS!'' He screamed, raising his left hand and pointing it towards Kalawarner, a bright light shining on his arm and a strong gust of wind being sent towards the fallen, shredding her clothes completely. (3)

When the light died down, a red gauntlet with a green jewel in it and two golden spikes on the side.

''Is that a sacred gear?! I got better things to do, will let someone else deal with this crap!'' Kalawarner said and then flew away.

''So what's the Sacred Gear? This?'' Issei asked himself, looking at the gauntlet at his hand.

-Occult Research Club-

''Yes. Congratulations, you found it. Now that it has been activated, all that you have to do is decide is when want to turn it on or off.'' Rias said to Issei, the gauntlet vanishing from his hand right after.

''Thank goodness, that would really slow me down in my alone time.'' Issei said with a smile, looking at his hand.

''I'm so proud of you Issei.'' Akeno said from beside him, bringing both of her hands to her chest.

''You are?'' Issei asked, rubbing that back of his head sheepishly, 'thanks.'

''That does however put in a bad position, not only do the fallen angels know that you are still alive, they also know that you have been reborn as one of us, this is bound to make things more complicated.''

''Yeah, I am so sorry.'' Issei apologized, lowering his head.

''I know that it was just an accident that you ran into her, but remember, don't get carried away now that you unlocked the Sacred Gear and try to fight them alone, that is disrespectful for the rest to us.''

''I understand...'' Issei sighed, ''I'm tired, I'm going home.'' Issed said, leaving the club-room.

''Exaggeration much? He's still new, why did you have to scare him?'' Akeno asked, looking at the door.

Rias sighed, perhaps she did exaggerate a little and putting off her earlier frustrations on Issei, but she still had a good reason, ''I'm not trying to scare him, I just don't want him to overestimate himself.'' Rias replied, biting down on her nail.

Akeno nodded silently, though she knew that it wasn't the only reason Rias was harsh with him. Naruto's words really struck a cord in the two.

-Somewhere else in Kuoh-

''My my, finding a fallen angel now? What a surprise... Though when was it that your kind took to walking around naked?'' Naruto asked Kalawarner with a grin, who was on a crater in the ground, courtesy of Naruto.

Those were the last things that the she heard before the world went black...

(1) - My grandpa is blind and that is the way I guide him when we go for a walk, it is so far, the best way I have found to guide him across crowds because he is always like 1 or half a step behind me, and thus he notices when there is a step or elevation through me.

(2) - Thank goodness it was his arm that he felt as the strongest...

(3) - Clothes are made of paper in this anime...

I am new to the world of fanfic, but I was told that people don't normally like OC's, what do you guys think of Yui.
