Disclaimer – I do not own Naruto or High School DxD.

This is my very first story, because I knew that High School DxD and Naruto is popular in this site so I decide to make a crossover of this one as my debut story. My writing skills are still unpolished because I am still studying English, it wasn't really my third language so I am kind of bad in it. This is just a prologue please leave me some reviews in the review section, I need someone input about my writing and if there is something wrong and something that needed to be changed.

Thank you!

Chapter Start.

Standing at the edge of a cliff surrounded by thunder strikes that came from the sky covered in dark clouds, in front of a raging sea was a man standing firmly. His white cape fluttered due to the unforgiving wind, but despite all of it the man standing at the edge of the cliff held no fear as his blue eyes hardened with his spiky blond hair fluttering wildly making it look more spiky. His outfit consists of a burnt orange high-collared jacket, with the wrist and hem of the jacket having three ring patterned black stripes in it, his black pants tucked within his black high cut sandals.

His hands cross in his chest with his right hand completely covered in white bandaged, in front of him there is nothing but disaster as the raging sea swallowed the surrounding island with its massive waves, the thunder strikes the ground and the trees destroying everything and burning it. Behind him the mountains has been shattered and destroyed. Black smokes raising from the ground towards the sky as the villages burns followed by the screams of the tortured souls but the boy who looks to be of age seventeen or eighteen paid it no heed as he stood at the edge of the cliff with a look of determination in his face.

Ignoring the tons of bodies laying behind him.

It is as if he no longer worries about anything and has put all of his attention to the unseen foe that was standing hundreds of feet away from him. He did not even flinch when a thunder strike the cliff he was standing on, and reveals himself to be unharmed, he did not even batted an eyelash when a powerful gust of wind passed him by.

He no longer fears anything for he has nothing to lose for he already has lost everything, from the monster walking towards him.

Standing hundreds of meters away from him, as if the raging sea wasn't even bothering it. It's massive body towered even the tallest of mountains, its lone ringed crimson eyes with nine rings glared at him with nothing but hatred and desire for destruction. Its ten massive tails swings hypnotically and every time it would sway, the sea would unleash another tall and damaging tsunami that would engulf an unfortunate island.

Its massive maw opens as it raised its head in the air as if it was going to swallow the moon, a circular blood red orb the size of a small hill appeared above its open maw as black energy circled around it as if it is absorbing all the evils of the world. Terrifyingly the ten-tailed beast swallowed the massive ball of energy and not a second later its whole body started bulging as if it is going to explode, but before it happens it opens its massive maw once again and from its maw a long massive beam of crimson energy emerged and flew towards the boy.

When it appears that the beam was going to swallow the boy the beam started condensing into a giant ball of destructive energy as it hurled towards him. But the boy did not appeared to be worried at all as he stared the destructive energy when it appear as if it was going to swallow him the boy finally raise his left hand and in a shocking spectacle the boy swings it as if backhanding something.

And after doing so, something like a miracle happened as the destructive energy that disintegrates everything it passed on, changed its direction as the boy slaps it away and hurled towards an unsuspecting mountain that suddenly got engulf when it exploded erasing everything in it along with all the living and none living beings in there.

But the boy knew for a fact that there is no longer any living being in that place for he could no longer feel any trace of a human being or even animals in this world, for all of them had been devoured or killed by this massive evil being in front of him.

"Let's end this Shinju, once and for all. This will be the last time that you will appear." The boy merely whispered those words and yet it resonated with the air and were carried all over the place, had there been any living being they would hear it.

"And how are you going to do that boy." The mocking voice of the massive creature in front of him boomed all over the place, with its eyes twinkling in amusement and its voice dripping with sarcasm.

The boy's blue eyes morphed and to the shock of the monster in front of him, his eyes turned into something so similar to his yet so different. Veins was surrounding the edge of the boy's eyes and instead or purplish red like the monster, his was pure blood red and has more powerful glow into it. It looks so much like those accursed man's eyes, the man who had took his freedom and sealed him into the moon.

"This." Those were all the words that left the boy's mouth as the whole world suddenly got enveloped by golden pillar of energy, and had anyone in space looking they would see the whole planet glowing bright golden reminiscent of the sun itself.

No one in space knew what happened but not a second later when the massive planet got engulf by golden energy it suddenly exploded accompanied by a powerful shockwave that resonated all over the galaxy shaking every planets and causing a massive amount of supernovas and creating a massive black hole that swallows all the debris.

No one knew what happened but in the far future, that massive explosion would become known as the big bang.

/Scene Change/

"How long are you going to sleep?" said a person standing near the window with her arms in her hips as she taps her foot on the wooden floor with a stern look on her purple eyes with her beautiful pink lips set into a scowl. "I heard that your store was closed yesterday for reason unknown, but I am not going to let you skip work today without a proper excuse and I know for a fact that you are not the sort of person who easily got sick." She forcefully opened the red curtain allowing the ray of sunlight to enter the room and flying straight to the person in bed face along with lighting the room up showing the full appearance of the girl.

She is a teenage girl with an attractive and mature face accompanied by a cute slim figure, she has shoulder length black hair cut into a bob cut style with bangs even out, she was wearing a red rim oval shaped spectacle and has purple mature eyes, she has a golden colored clip on her left side.

Her outfit consists of a light shirt with detached sleeve and shoulder less revealing her creamy white skin with a light blue garter supporting it and hiding the garter of her underwear, for bottoms she wore a short blue shorts that stopped at her upper thigh and was wearing a long black socks which ends just above her knees.

"Now, stand up and get dress and go to work, I took the time to come here just to make sure that you go to work, just because my sister is your employer does not mean that I should show you favoritism, now, get up." She finished with a scowl as she remove the blanket from the person lying on the bed.

It was a young man who appears to be of age 18 or 19, but instead of going into college he's now working as a cook, although he was the one who chose that position because it is what he knows best due to him being the one to cook for his food all his life.

The young man has neck length golden blonde hair that glows whenever the sunlight hits it, he has elegant yet thin eyebrows and from his lidded eyes peeks a pair of glowing crystal clear blue eyes. His outfit consists of a white sleeping shirt and blue knee length shorts, not too bad considering that he's only using it as a sleepwear.

"I'm too tired to go to work…" the young man mumbled earning an annoyed glare from the girl who merely sighed in irritation.

"Don't give me that, it is you who said that you wanted to work, and I was even forced to buy that shop for you because you said you wanted to work as pastry chef." The girl rebuked with a sigh as she walks towards the bed to force the young man to get up. She didn't really know the circumstances on how he got in her home back then, but all she knows was that he had already been there before she was born and was a part of her family, who acts as her elder sister advisor before he become her caretaker.

Which is why when she was, sent to study in the woman world to learn how the humans live, he came with her to be her guardian until he had deemed her fit enough to live on her own in the human world. Instead of returning to the Underworld, he decided to stay in the human world to live like a normal human, although she's annoyed by it but she was happy that he decided to stay for she had become attached to him.

After all whenever her sister is busy to play with her back then, he would always be there to entertain her and whenever her parents are busy he would be the one to teach her, for as long as she knows he had been a constant in her life that everything she knows had only been thought by him. She even doubt that she would be in here had it not been for him so it was actually obvious for her to be so attached to him which is why she was so happy when he decided to stay despite her not showing it.

Although she was sure that he knows it because she was the one who volunteer to buy the pastry shop for him, even though she claims that it was only to thank him for everything that he had done for her. She was sure that without him, she would be more uptight and serious about life, although she still is but she knew how to enjoy life.

Maou knows just how much annoying he could be whenever he sees her starting to act like a frigid who knows nothing but studying and working, it was him who taught her everything she knew and understand in life. Although the way he acts like a lazy bum irritates her sometimes even though he used to be so hardworking back then, him being lazy wasn't really the one that irritates her its just that it made her realize that she do not really know anything about him because his actions as of now contradicts his actions back then.

"Now, get up." She firmly shook his shoulders, she wasn't the kind of person who would wear outgoing clothes like this but since there is no school today and it's a special occasion due to her not having work today, means she could spend some free time with him.

"Ugh, fine." The young man finally got out of bed with his hair completely ruffled as he walk towards the bathroom lazily.

"Hurry up." The girl commanded sternly while the man waved his bandaged covered hand, another one of the things she did not know of, she didn't really know what that bandage is for and it is impossible for it to be an injury because for as long as she know him he had already been wearing that bandaged.

She did not want to pry but she admit that there are times when she wanted to ask what that bandage is for, although she speculates that it must be some kind of seal or something. It was due to the strange markings in it, also because he once stated that he would only remove it when he meets an opponent that he could not beat as he is.

She glance towards the bathroom door when she saw him came out with his hair now tidy, although still retaining its spiky disposition but it look much more presentable now. He's now wearing a long sleeve white button up shirt accompanied by black pants and black shoes while he tied an black apron around his waist, he got his apron mix with his clothing since his shop is just down stairs, the first floor of the building is the pastry shop while the second floor was his room.

"I get that you have a free time but why are you here though?" The blonde looked up before he shook his head "Right, don't answer that it's Saturday."

"Even if it is Saturday, is there a problem with me being here?" The girl responded calmly with narrowed eyes "If there is, just say so and I shall leave immediately."

After hearing that the boy immediately started panicking,

"Ah! No that is not what I mean, it's just that you don't usually visits me so it is a surprise there is no meaning in it."

The girl nodded her head with a firm look on her face "I told you that I'll be visiting your shop once I am finally free if only to see if you really are working properly, I am kind of relief when I started hearing from the other students about this shop." She nodded her head in approval "It seems your pastries are really popular, so I thought you are doing your job perfectly but imagine my surprise when I heard that you were closed yesterday yet you did not inform me."

The blond looked away sheepishly as he scratches his head "Ah, well about that I… have some stuff to do hehe." He chuckled nervously while the girl merely narrowed her eyes towards him.

"And that is?"

"It's complicated." She wanted to ask what he meant but refrain herself from doing so when she saw the look in his face. It was the same look she used to see in his face when she was still a kid, but could not understand what it is, but now that she could understand what it is, she could not bring herself to ask why he have that kind of expression.

"Very well, I shall no longer ask what it is but now onto the reason why I am here, every time I hear someone gossiping about the 'hot' blond pastry chef. I could not help but be curious, they say that your pastries are top class. I've tasted your cooking but I know for a fact that making pastries and cooking foods are two different things. So I wanted to have a taste."

"Is that so?" the blonde murmured with a sly smile as the both of them went downstairs and enter the shop, while the girl merely took a sit in front of the counter while the blond went inside the kitchen. "I could not help but get the feeling that you didn't come here just to taste my pastry but because you are jealous, because I am spending time with other girls while you are busy sitting in a chair signing paper works."

"S-shut up, ahem." She scowled with her cheeks tinted pink before calming herself with a cough in her knuckles "It is not for that reason but you are correct, I came here not only to taste your pastries but for another reason."

"Business related?" the tone in the blonde's voice was serious indicating that he knew the reason why she had come to him.

"Yes, a few weeks ago I felt an intrusion on the barrier that you had set, it wasn't really surprising because usually there are visitors that come here in Kuoh to negotiate. But the thing is the intruders came in her not for negotiation but for something else, usually there would only be 3 to 5 but the intruder's has an army of rogue exorcist."

"Ahh, four fallen angels along with those rogue exorcist." The blonde nodded his head, not that she could see because he was in the kitchen.

"So you knew, yes they are and I believe they are here to observe somebody, do you know who it is?" The girl asked as the blonde finally came out with a box of different colored cookies with jams in his hand.

"Yep, they are probably here to observe or possibly kill the wielder of the boosted gear." The blonde responded with a smile as he handed the box of cookies towards the shocked girl.

"Are you sure about that Naruto? The wielder of the boosted gear is in here?" she asked in shock, if the wielder of the boosted gear is here she would have known it as it was impossible to escape her radar especially if someone had such powerful sacred gear.

"Yep." The now named Naruto nodded his head with a grin "In fact he's going in your school, and is also a regular customer in here."

"In school?" That's strange, if that user of the sacred gear in Kuoh high then she should known it by now, she was surprised when Naruto gently tap her on the nose with his finger.

"Don't worry about it, you didn't sense him because the presence of dear old Ddraig in him was too weak, probably because he has no training and was completely unaware that he the boosted gear in him." That is also one of the mysteries surrounding him, he's throwing the name of the big shots as if he knew them personally. "Anyway, don't worry too much about that if their presence is bothering you then I'll take care of it immediately. Just take this and enjoy, you come here for this right Sona-chan?" he insert one of the cookies in her mouth with a playful smile on his face.

She would have reprimand him for doing something unnecessary had it not been for the flavor of the cookie exploding in her mouth, she could not describe the taste but it was Naruto-ish like, it was a taste that nobody could ever emulate, a taste impossible to achieve unless you are Naruto.

"This…" she gently picks up another one while eyeing it with her left hand on her cheeks with a small blush on her face, "Is surprisingly good, no wonder this is so popular."

"Yep, I even have pureblooded vampires as regular customers." Naruto grinned at her as she snaps her head towards him with a look of surprise.

"When are you planning to tell that to me Naruto?" Her voice was harsh as is her glare.

"Well, I just did." He tilted his head with a smile earning a twitch from her before she sighed and merely popped another cookie in her mouth, too stressed already to think of other things.

"So, do you any plan for the day?" Naruto ask as he started wiping the glass counter with a cloth while Sona merely kept silent as she ate the cookies.

"Nothing much, I am practically free today and I allowed my peerage to have some freedom for today, they said they are going to the pool."

"Why not go with them? Its not like you have anything to do anyway?"

Sona shook her head in annoyance "You are an idiot."

"Eh? What do you mean!?"

"Nothing." With that she merely kept eating asking for seconds when she ran out of cookies, while pretending to ignore the childish man in front of her.

Fallen Angels and Rogue Priest's huh? He's definitely going to use this as a blackmail for that Perverted Fallen Angel.

Oh, right he's currently short on staff, those people would surely come in handy.

Unnoticeable by Sona, a hidden smirk appeared on Naruto's face.

Chapter End.
