Hey hey dear readers, I hope you all fair very well. As promised (or more like I told myself at least countless times over and over again), I present you with my second story, which will be more of a side project next to my main story. But as I was quite eager to finally write the first part of this new idea down, I wanted to bring this story out for you to enjoy as soon as possible. I don´t want to tell you much right away, just let yourself be surprised (those who read my preview somehow know what to expect).

Also, check out my main story, Lost in Darkness, if you want (a little publicity doesn´t hurt).

Note: I have the feeling I should say this before: as you know, the plot of Highschool DxD is greatly connected to the Bible content and many other different cultures and their own respective religions. I´m just saying that this is Fanfiction and I may change some things for my own pleasure to better fit with my story, so please don´t feel insulted or saddened when I change something from the Bible or so on. Everything I write is not real and shouldn´t be considered as such, this story is just for my readers and mine enjoyment. Even though I´m not religious, I respect the different religions and cultures all around the world, so please don´t take serious what I write. It is not my intention to insult your belief.

I just wanted this to be clear. Thank you.

Enjoy!

I do not own Naruto, Highschool DxD or Fairy Tail.

A World Worth Saving

Chapter 1: A Ray of Hope

I often wondered if the future was set in stone.

And if it truly was set from the very beginning, why even bother to fight against the odds in our lives? Where was the meaning behind our constant fighting? All the pointless fights between us humans just so to make our lives better? To fight for our homes, our families … to fight for what we thought was right.

A difficult question if you ask me.

A question I still ask myself nowadays.

I thought that I had seen the horrors of war. The true horrors and pain that swallowed the Shinobi Nations with the ongoing Fourth Shinobi War. I thought that it was the most terrifying thing that would ever threaten our lands.

But I was wrong. So terribly wrong with my assumption.

I thought that after Madara's defeat and finally, with Ootsutsuki Kaguya's escape to one of her dimensions, peace would finally spread across the nations. And it did … for a few years.

The war had ended after only two days, but still so many Shinobis had died in the mist of Obito's and Madara's madness. I still find it hard to believe that we managed to win the war after all. Without Sasuke's aid in the final battle, we would have surely lost.

Madara had been defeated, but then came an even stronger foe.

Kaguya Ootsutsuki

It was a battle we could not win. Even Sasuke's and mine combined powers were not enough to match her. She was just too strong. No human being could fight her on equal grounds. All seemed lost in the end. We started to lose our hope.

The moment she tried to kill us, Kaguya suddenly stopped in her attempt. She only looked me in the eyes before a lone tear escaped her right eye. And then she vanished. Vanished to one of her self-created dimensions, never to be seen again.

But before she did, I heard her soft melodic voice inside my head.

She gave me a warning. That some day in the future, I would call her again for assistance. To gain her assistance against an unseen terrible threat. She would wait for me. Wait for the day, which would mark the end of all things.

I did not believe her words. I was foolish back then … foolish and young.

And so the Fourth Great Shinobi war finally came to an end, the Mugen Tsukuyomi of Kaguya lifted wit her departure, ending the illusion casted upon mankind. It was a time to celebrate. We were hailed as heroes, Sasuke and myself. None of the others knew what had happened, not even Kakashi or Sakura. Even Sasuke did not know of Kaguya's warning.

The war had cost us deeply. The wounds were still fresh and so it was decided to keep the alliance between the Five Great Nations sealed for all eternity. To never let such a pointless and horrible war happen again. A wonderful decision … back then, it was a great moment for all of us.

We came back to our village to mourn our losses. So many had died. So many of my friends were dead, killed during the mist of war. I still remember their names, engraved into the memorial stone of Konoha. Neji … Lee … Hinata … Choji … Ino … Genma … Kotestu … even Iruka-sensei, Guy-sensei and my Jinchuriki fellow, Kirabi.

They died protecting our world from a mad man's dream.

People died for less.

I mourned for a long time, feeling responsible for their deaths. But I overcame my grief, I needed to or I would spit on their belief and the sacrifice they had made … Sakura's and Baa-chan's beating helped a lot for me to see reason.

It was a rough time afterwards. We still had much to do, rebuilding Konoha from Pain's attack, improving relationships between the other villages to maintain our alliance and many other things. Tsunade-baa even promoted me and Sasuke to Jonin, even going so far to name me the ambassador to all the other villages.

It seemed I left quite the impression on the other Kages, even more so on one.

She was truly one of a kind, but I was still young and fairly … inexperienced with women, especially a grown-up woman.

Two years after, I finally managed to express my feeling for her. You could guess my joy when she returned them, I was so happy back then and our wedding was just too perfect to be true. I even managed to convince Sasuke to be my best man … ah the expression on his usually stoic face when he learned of my soon to be wife. That alone was worth it.

And only one year later did my wife grant me my deepest desire … my true dream. The dream of a family. Life could not get better for me, I was the happiest man ever.

But it did not last long.

None of us could have predicted it. None of us even knew how big the world, or rather the universe exactly was. We always thought that mankind would destroy itself. But it did not come from our world … not even from our own dimension.

It was madness.

Nothing could have prepared mankind for the upcoming disaster. Our extinction … all we stood for, all we had fought for, all our dreams and hopes … destroyed in one single week. Against something we did not even know existed in the first place.

Something against we stood no chance to win.

Our entire race was doomed to extinction. Not a single human escaped the planet's destruction.

Except for me.

Till these days, I still do not know how I survived. Why did I survive? Why was I saved from death while my family, my friends, my home … everything I ever fought for, were destroyed by the Legion. Even now, I do not have an answer to that question.

I came to another world. Or dimension to be precise.

It was a strange world. Even though humans lived on this planet, they were not like me. They were pitifully weak, both mentally and physically. How they managed to survive without Chakra I did not know. And then I slowly started to realize that I was the last one. The last survivor of my own home world.

I was alone in this new world.

I did not know what to do any longer, I had lost my spirit to fight and live, the loss of my family being too much to bear. And so I simply wandered across the world, trying to find something to do, a new purpose to live. And as the years passed on, I became aware that I did not age any longer, I still looked like I did on my twentieth birthday. I had not even realized my own powers, power I did not have before the destruction of my home world.

I had become so strong, I had become something more, something stronger than I could ever imagine.

It took me decades to master my newfound powers and during my travels, I learned more of this world. A world not just inhabited by humans, but also by Youkais, Angels, Devils and even Gods. The surprise was evident on my face when I first became aware of their existence.

My curiosity rose.

The Underworld. An interesting place, even though I preferred the human world. I quickly lost interest, especially since I visited the place during a war that swallowed the dark lands. A war between Devils.

And I had enough of war.

It was during that time that I met her.

I found her injured, near the point of death, between the frozen bodies of countless Devils.

I healed her. We got to know each other, we took pleasure in our talks and when I finally left the Underworld, she came with me.

We travelled the whole world for a century and before I knew it, I once more had a purpose in my life. I was no longer alone, I was happy once more.

And I knew that I could not let the same happen to this world. To my new home.

The moment I looked into her beautiful eyes, I knew what I had to do. I knew what and whom I had to protect.

Even this world was not save from them. They would find this dimension … and they would destroy it. It would suffer the same fate as my home. I could not let that happen again.

I might have lost my will to fight and to live … but now, I had something to fight for.

Yes, it would not repeat itself.

This world, full of humans, Devils and Angels, so unprepared for the real threat outside of their world … they would not know how to protect themselves from the shadows that lurked in the dark parts of the universe.

It was my duty.

My fight.

Yes

This world was worth saving.

I still remember the day it happened. Even though I desperately tried to forget about it … but to no avail.

The day, which heralded the beginning of the end. The destruction of my home world.

It should have been a joyful day. A day to celebrate our victory. But what came … we could not even imagine the horrors that were unleashed upon us.

Why had it come so far? Why did we have to suffer so much? Fighting for our mere survival … a vain fight if you asked me.

I can still remember the happy times I shared with my friends and family. Before it all started … before darkness consumed our home.

Yes, life had not always been easy, my siblings and I had much to endure during our earlier years. Having lost our parents while we were only but kids, I was responsible for my two younger siblings. I needed to protect them. We, no I … I was feared in our village, feared for something I took control over.

I never wanted this power. But I had to protect my family. The village did not want us … did not want me any longer and so we were forced to flee. To search for a new home. A true home.

And a new home we found. Yes … we finally found our place, a place full of friends, a warm home, which welcomed us, despite my strange unwanted power.

I was so happy to finally have a place to call my home. To finally know my family in safety. It was the start of our new life, a good life.

The years passed on and the guild, which we joined, became even stronger and well known over the continent. I learned to live with my power, to control my power and grew stronger with each passing year.

But the moment I lost … I thought that I had lost my sister … I became weak. I became tired of the fighting and simply wanted a calm life for my remaining sibling and myself. Those three years were truly a difficult time for us and even for my guild, which I considered family.

But she was not dead … my sister did not die that faithful night like I had thought. We were reunited once again and together we faced many adventures. Strong enemies, who threatened our world … but we always managed to win in the end. The bonds of our family and friendship were always victorious.

Even after we awoke from a seven-year stasis, we managed to recover. Much had changed during these years, our guild had suffered greatly with our departure and we had to show the world once more the strength of our guild. A perfect chance to do so came months after.

The Dai Mato Enbu. The Grand Magic Games.

We could prove ourselves. We could reclaim our position as strongest guild. We were excited to win … we aimed to win, to fight for those who were left behind. We needed to make amends, as they had suffered, cried … for seven years. We had to fight for them.

The competition was strong. The fights were ruthless. Much was at stake.

While we slowly managed to regain our reputation and the support of the audience, we never suspected what happened behind the scenes. The Dai Mato Enbu were only a cover. A cover to absorb the magical power of the fighting guilds.

There was a portal.

A portal, which was going to be used to travel back in time … to kill a certain dark Mage. The strongest Mage, who had ever existed.

Project Eclipse.

Their intentions were good, but … none of us could have known what would truly happen.

And the moment our team had won the Games, it began.

I still do not know how it really happened. I had not been there when the portal was opened. That probably saved my life now that I think about it.

We were truly foolish. Believing that the portal could also be used as weapon … a weapon to kill over ten thousand dragons.

How foolish of us … but we believed it. And we suffered the consequences.

The truth is … we were all played for fools, as the portal was never meant to be used as a weapon … it was not even meant to be used as a time travel portal.

In the end, the one who had manipulated us … was manipulated himself, believing that he could use the portal to reign over the world.

But it did not happen like he predicted.

I remember … a red light … the sky became blood red, the ground around the city shook and crumbled and then I felt it. This dark feeling, like nothing I´ve ever felt before. It was terrifying and only seconds later did the sound and stench of death swallow the city … before spreading over the whole planet.

I can never forget the screams of my friends … their cries … their fallen bloodied forms.

Nothing could have prepared mankind for the darkness that stepped through the portal. Death came and swallowed the land … it came and destroyed everything I ever cared about.

I was completely helpless as I watched the city burn, the countless dead bodies that were devoured by these … creatures ... those foul creatures, slaughtering every living soul that came across them.

So many died. It was … I still am unable to find the words to describe it … I only want to forget about it, but the pictures still haunt me in my sleep.

I saw them dying one by one … one by one of my friends died a painful gruesome death, their very souls ripped to shreds. I … I saw my siblings dying right in front of my eyes. My little brother and … even my little sister. I held her blood-covered body in my arms while she drew her last breath. She … she smiled at me … her bloody lips trying to smile like she always did, her eyes slowly losing their beautiful shine.

I was forced to watch her die a second time … I felt so weak that moment. I could not even protect myself. I did not even want to. I just wanted to follow my family and friends.

But death did not come for me that day.

I was saved.

I do not know how he appeared … I do not know where he even came from. I just know that he did.

My savior stood right in front of me, killing the creature that threatened to claim my life effortlessly. He then slowly turned his head to look down at me.

He gave me a small smile and before I could react, my world turned black.

I awoke in this world, so different from mine.

I never forgave myself … letting my family and friends die while I managed to survive. I often asked myself why I survived? Why could not my siblings be saved instead? Why was I saved and not them? I still do not understand … and I still have not adapted to this new world.

I did not deserve to live.

But I did. I survived the destruction of my home.

I know that my savior managed to rescue some other people from my home world, but I did not want to meet them. I grieved the loss of my siblings and friends. I do not know how to live any longer, how to live without my family.

I never really thanked my savior … I still think I did not deserve to be saved that day.

I lost my belief and hope.

I'm useless.

Nighttime, the Capital City Lilith, Underworld

Silence reigned over the largest and most populated city of the Underworld. Not many Devils were currently out on the streets, even though their race was mostly night active. But for the sake of the none-pureblooded Devils, mostly former humans, the flow of time was adjusted to match the one flowing in the human world. And so it came that even the true Devils adopted to the new lifestyle, sleeping during the artificially created night.

After the Great War hundreds of years ago between the Three major Factions, known as the Devil Race, the Angels from Heaven and their counterparts, the Fallen Angels, many things had changed for the Underworld.

With the loss of their four strongest leaders, known as the Yondai Maou or the Four Great Satans, peace with their mortal enemies was essential for the survival of the Devil race. What followed was not a real peace treaty, but more like a fragile truce between them … but it was better than nothing.

The Three Factions had lost their leaders and most of their forces, they could not allow another war to occur or it would mean the end of them all.

Unfortunately, not all Devils were satisfied with this ´truce´, seeing it as a disgrace to their proud and superior race. They wanted nothing more than to continue the war, even though it would only lead to their destruction. They wanted to avenge the death of their fallen leaders.

But not every Devil had the same opinion. Many Devils, especially the younger generation, wanted to maintain peace with the Angels and as no compromise could be found, war was inevitable.

The Underworld, mostly the territory controlled by the Devils and not the Fallen Angels, was swallowed by a terrible Civil War, bringing death and destruction to the lands. The losses were heavy, too heavy, as they had not yet recovered from the Great War.

The descendants of these Four Satans, even though fighting fiercely, were slowly pushed back by the younger Devils, who had formed an alliance to resist and take control over the Underworld. This Anti-Satan faction managed to banish the few remaining loyalists to the most remote regions of the Underworld, thus ending the Civil War after many years.

Four young Devils, responsible for the victorious ending, took the leadership over their fellow kin. Since that day, they were known as the new Yondai Maou, taking the position of Lucifer, Leviathan, Beelzebub and Asmodeus.

Lilith became the new Capital City and the seat of the Four Satans.

It was one of the most secured places in the whole Underworld, making it nearly impossible to infiltrate. But now that the Maou were gone to their respective family homes, their guards had also left with them.

A perfect opportunity to strike.

A lone figure could be seen standing on one of the many high houses in the middle of Lilith. The figure wore a simple black coat, the face hidden by a hood, giving no sign of the figure's identity. Sighing deeply, the clothed person gazed at one of the tallest buildings inside the city.

The bank of Lilith, Crocus.

Deep within the coffins of the bank laid something of great value, something her master wanted … no needed at all costs.

And she would bring it to him. She would not fail.

Inside the bank, hundreds of meters below the earth surface

It was dark inside the narrow passage. Dark and moist, as water dripped down from the cold stone roof. Only a few weak light sources illuminated the long corridor. It was only one of countless gangways below the Capital Bank Crocus, the Devils having built a true web of passages hundreds of meters underneath the earth to guard their treasures.

But this passage was special. It only led to one single vault, buried deep underneath masses of hard rock and dirt.

"AAHHHJOOOUUUUU"

The silence of the dark corridor was shaken by the sudden sound, followed by an amused chuckle.

"Bless you Keso! I hope you haven't caught a cold."

"Ah thanks man … oh, how much I hate this fucking post! Any idea when we'll be relieved?"

His partner only shook his head. "No idea, but I bet we still have guard duty for another four hours or so…."

Keso sighed deeply, wiping his nose clean. "Shame. I fucking hate it down here! Always wet and so stuffy, not the forget the horrible smell … and even after all these years, I still don't know what the hell we are even guarding here?"

The second Devil guard only shrugged, leaning his back against the cold stone, his spear loosely held in his right hand. "Who knows … I bet not even the higher-ups know what it is, but that shouldn't concern us. We only have to guard it, nothing more nothing less."

His partner scratched his chin. "If you say so, but I just wonder who the hell would want to steal something no one even knows anything about … this is just plain and simple an useless task."

"Maybe you´re right."

Before Keso could voice his other complains, the air suddenly grew cold, making the two guards tense.

"Oi … hasn't it just gotten much colder?" His fellow guard felt the same, seeing as even their breaths became visible to the naked eye.

The two Devil Guards grew nervous, looking around the narrow corridor into the darkness. "I've got this really bad feeling, maybe we should call rein…."

Keso could not even finish as his voice was swallowed by the torrent of blood that escaped his mouth. His fellow guard was not even able to react as he suffered the same fate, something sharp having slitted their throats in less than a second.

Both Devils sank to the ground, blood spraying out of their throats. They desperately tried to stop the bleeding by pushing their hands against the horrendous wound, but they knew it was in vain.

A lone figure emerged from the dark of the gangway and calmly walked in their direction. Keso watched the black-clothed person when she came to stop right in front of the sealed door to the vault. His vision became blurred.

A last gurgling sound escaped his bloody lips as a sharp spear of ice pierced his hearth, killing him instantly along with his partner. The intruder did not even bother to look at the downed forms of the two guards, who were lying lifelessly in their own pool of blood.

Her attention was solely fixated on the heavy metallic door, protected by powerful Sealing Magic. She touched it with the palm of her right hand and slowly, a layer of thin ice spread over the door. The powerful use of magic made even the passage freeze over with thick white-blue ice.

The door hinges froze and burst into thousand small ice bits. Sending another powerful magic pulse out to disable the last magic seals, the heavy door finally fell to the ground, creating a strong cloud of dust.

The figure stepped into the small vault, her eyes immediately landing on the weakly illuminated chest on the stone podium. She needed to act quickly now. Surely her earlier power rise had drawn attention. Better she would not risk a confrontation now. Her master counted on her.

Walking in front of the simple chest, she touched the cold rotten wood and with another wave of her magic power, it opened.

Her eyes glowed underneath the hood as she saw the reason for her coming.

Her master would get his wish.

At the same time, Gremory Estate, Underworld

Her home was still as she remembered it to be. Even though it had been only three months since her last visit, it still felt like years to her. A small smile graced her delicate lips as the young woman walked across the impressive hallway of her family estate.

"Welcome home, Rias-sama."

Said girl gave a smile at the bowing maid before she resumed her walk. Being the second child and heir of the prominent Clan, Rias Gremory was well known throughout the Underworld. Even though she disliked to be seen as only the princess of her Clan, she was still proud of her family's name, being one of the last pureblooded Devil Clans after the Great War and Civil War.

Still, she often wished to be seen as only Rias … just Rias. That was one of the main reasons why she went to the human world where she was not known for her stature as Devil or Gremory Princess. But she still missed her home and so she often came to visit her family in the Underworld.

Stopping in front of one of the many mirrors, which decorated her family's estate, the young woman gazed at her reflection. What she saw made her hum in appreciation, knowing very well why she was seen as the most beautiful girl in her school.

Her long beautiful crimson hair, which reached past her waist, was truly what made her stood out from the rest. She was really proud of her silky hair, several bangs covering her forehead and framing her pretty face. Her eyes were of a brilliant blue color with a hinge of sea green, her creamy pale skin doing well to accentuate her feminine features and plump lips.

She was even one of the tallest girls in her class and of course, due to her being a Devil, her body was far more developed than an average human girl, although much to her ire, she would never be able to be best her friend and Queen in certain aspects. The Gremory heiress was clothed in a yellow blouse, showing a generous amount of her ample cleavage while her black skirt went slightly past her knees, giving a good sight to her creamy long legs. To complete her outfit, she wore black high heels and a blue jacket against the cold of the night.

Yes, Rias could be more than proud of her figure. If only someone could see past her beauty and see the inner her. If only….

Shaking her head to get rid of the upcoming thoughts, Rias quickly stepped through the double doorway into the large spacy living room, illuminated by several huge lamps on the ceiling. A long wooden table took most of the space in the middle of the hall.

Rias smiled as she saw her older brother sitting near the head of the massive table, silently going over countless papers, which needed his signature. The eldest child of the Gremory Clan looked up from his paperwork and his eyes immediately brightened when he saw his little sister.

Before she could blink, Rias was already in his arms, being spun around while her brother rubbed his cheek on hers.

"RIAS-TAN"

Her cheeks immediately reddened in embarrassment, struggling to get out of her brother's vice hug. "O-Onii-sama … put me down! Now!" Not wanting to earn her ire, the male quickly complied and put her back on her feet, although he smiled brightly at his lovely little Nee-chan.

Adjusting her clothes and trying to regain what little dignity she had left, the crimson-haired princess huffed before slapping her brother's chest, making him wince. "Jerk! You haven't changed at all during these last months … but, but I still missed you Onii-san. I hope you stay for a while? Father and mother would surely be happy to have you here for a bit longer."

"Hai hai" Chuckling, her older brother went back to his seat, followed by his sister who sat down on a near chair. Brushing some strands of hair behind her left ear, Rias gazed over the massive amount of papers on the table. "Looks to me like this won't be a vacation for you, huh?"

Sighing deeply, her older brother massaged his temple. "You have no idea, Rias-tan. I fear I can't spent much time with you after all, even though you need your big Aniki so much … sniff … already seeing your hurt pretty face makes me so sad … sniff…."

Rias right eyebrow twitched dangerously, although her face remained impassive as she watched her brother wiping his fake tears away. ´Keep telling that to yourself Onii-baka … seriously, why do I have such a siscon as brother….´

Yes, her brother was truly an interesting Devil. Being born as the first child of the current head of the Gremory Clan, he would have been the heir, but due to his efforts in the Civil War, her brother along with three other powerful Devils took over as the new Satans.

Even if it was hard to believe, her brother was the leader of the Four Satans and currently, the strongest Devil among his kin. He was Sirzechs Lucifer, formerly Gremory, but most of all, he could be the most childish person she had ever met in her life, despite him being the leader of the Yondai Maou.

Yeah, even she still found it hard to believe sometimes….

Sirzechs could be viewed as a male version of her. He was quite handsome, if she believed the talk among the female maids of the estate, having the same bluish-green eyes as her and shoulder-length crimson red hair, as it is usual in her family. He was nearly a head taller than her, clad in his usual black evening robe and not his traditional Satan attire.

Sending his paperwork a heated glare, Sirzechs turned his attention now completely to his sister, grinning brightly. "So Rias-tan, what brings you here at this late hour? I know, you missed me too much, didn't you? Yes no need for further words … I know I need to look more after you, my little Rias-tan is still too young to live alone ... I should have known! Mmh, if only I could visit you more often, having your big Aniki with you would surely brighten your day, wouldn't it Rias-tan?"

Groaning, the young woman slapped her right cheek in embarrassment and fury. Only her brother, despite loving her more than it should be, always managed to bring her nerves to the point of breaking. "Nothing of that sort Onii-baka … though I did miss you."

Ignoring his cheeky and stupid grin as best as she could, Rias demeanor became serious again.

"I just came back for my monthly visit and I wanted to see you all before going to bed, although I may guess Tou-san and Kaa-san are off to visit one of the other families? I can't feel their magic power inside the estate."

"Yes, they are currently at the ball, which is thrown at the Sitri estate, you know how close our two Clans are." The Maou put the pen on the table, leaning his head on his right hand palm. "But this is not the only reason for your visit, is it?"

"True enough." A small smile graced her delicate lips. "You may not believe it Onii-san, but I'm sure I have found a powerful new member for my Peerage!"

"Oh do tell so."

"A human student from my school has gathered my attention. My guess is that he has a powerful Sacred Gear inside his body … I even dare to say it may be one of the thirteen Longinus, although which one, I cannot say for sure."

Now that managed to raise one of Sirzechs eyebrows. "Interesting … it seems luck is on your side Rias-tan, having such a powerful servant in your Peerage is surely bound to bring you fame in the future. You still lack many pieces after all … so, when do you plan to reincarnate him? You're waiting for a better opportunity?"

Nodding, Rias blew another strand of hair out of her face. "I am not sure when I'll be able to reincarnate the Sacred Gear wielder, though I do plan to do it in the following weeks if no better chance arises. Fortunately, Sona has shown no further interest in him and given me even free reign to add him into my peerage … she is close to have a complete set of pieces, lastly I heard she managed to reincarnate another Sacred Gear wielder, the one she already had her eyes set on."

Sirzechs closed his eyes, chuckling slightly. "Ah yes little Sona-chan … Serafall-chan always speaks so highly of her little sister during our meetings. She seems to manage fairy well. Our little siblings grow up so fast and … sniff … I'm not able to see my little Rias-tan … sniff … during her growth … sniff…."

A tired sigh escaped her lips as Rias watched her brother going from serious into an emotional state, her left eyebrow twitching all the while. Fair enough, she should have gotten used to it by now….

Hearing little footsteps outside the hall, the girl turned her head and not a second later did the doors open.

"Oba-chan"

A beautiful smile sneaked on Rias lips as she extended her arms to welcome the small bundle of joy, who nearly crashed against her chest.

"Missed you, Oba-chan!"

The crimson-haired princess lifted the young boy off his feet, getting a good look at him. "Your aunty missed you too! Oh my, Mil-chan … you've grown so much in these last months, already getting much heavier and stronger, are you not?"

The small boy giggled cutely while enjoying his aunt's attention. "Yeah … not long and I'm taller than you, Rias-oba!"

"I am sure of it." Rias amused grin did not leave her face, bringing her little nephew closer to her chest while she sat back on her chair. Both family members giggled while the young woman rubbed her cheek against the small boy's one. "But you'll still be my cute little nephew!"

Millicas Gremory, her nephew and the son of Sirzechs Lucifer. The second heir of the House Gremory had only just reached his ten years, the little boy being nearly the exact replica of his father. Short spiky crimson hair and the same facial traits, although his eyes were a deeper shade of red. Her nephew was currently dressed in his pajamas, meaning he was just about to be brought to bed or he might even have sneaked out of bed … difficult to tell sometimes.

"Kaa-chan sensed you, Rias-oba, so I had to say good-nighty to you too!"

His cute face made Rias even happier before she started to tickle him, earning some cute laughs from her nephew.

In the meantime, Sirzechs watched the exchange with a small smile. The sight of his family always managed to raise his spirits up after hours and hours of endless paperwork. This was one of the moments where he knew that the terrible war he fought in had been worth it. Even though the Three Factions were not truly at peace, life had gotten better for the new generation.

He would do everything to maintain the peace for his race.

The Maou clapped his hands, earning the attention of the still cuddling duo. "Not that I want to interrupt this little family reunion, but should you not already be in your bed by now, my son?"

Millicas only grinned. "But Tou-chan, Rias-oba has come home … and Kaa-chan said I could come and say good-nighty, neh Kaa-chan?"

The doorway opened once again.

"He missed his aunt after all."

Rias smiled at her sister-in-law. "Of course he did, who wouldn't?"

Sirzechs sighed happily before his eyes fell upon his lovely wife. "Still, I am surprised you even allowed Mil-kun to come and greet her. Last time when Rias-tan came in the middle of the night, you didn't allow me to leave the bed to greet here…."

The Satan sulked while a small rain cloud floated over his head.

"But my love, you should have seen our son's cute face … I couldn't help but comply to his wish." Her gentle smile seemed to lighten up the hall. "One time does not hurt, you know how Mil-kun loves his aunt."

"Yeah" Millicas beamed all over his face. "You're my favorite aunty after all, Rias-oba!"

"I'm your only aunty, Mil-chan!" Rias smiled lovingly at her nephew, who giggled.

Smiling, Sirzechs turned to his wife, who came to stand next to him, her eyes never leaving her only child. "He didn't cause you too much trouble I hope? Normally he only wants to sleep after I told him a small fairy tale. How did you even manage to bring him to bed, Kagami-chan?"

Her smile never vanished. "I just promised to tell him the story how we meet all those years ago."

Kagami Belmont. The wife and Queen of Sirzechs Lucifer. Even though being a High-Class Devil to one of the noblest Clans, she was one of the kindest women Rias had ever met. She was not arrogant like most of her peers or even pampered, her older brother would not have fallen for her in the first place if she was.

The Belmont Clan was just like the Gremory Clan one of the 34 remaining Pillars these days, even though their numbers had suffered greatly during the Civil War. It was only due to the wealth and power of the remaining members that they were even considered a noble Clan even till these days. Their mastery over Earth Magic was unrivaled, but their true power lay in one particular member: Kagami Belmont. She was the only Devil who had perfected the use of Earth Magic beyond what could be considered possible, having gained control not just over Earth Magic, but also over Magnet Magic. Because of her Jiton abilities, Kagami was able to control Sakin, or Gold Dust Magic like it was commonly known, making her a fierce opponent and powerful ally during the Civil War.

And despite all her power, she never looked down on her fellow Devils. Her kindness was well known and gained her a lot of fame and popularity with the younger Devils. It was one of the traits, which drew Sirzechs towards her. Rias father had told her that his only son was a nervous wreck the first time he gathered the courage to ask her out. Their first date could only be seen as a disaster, everything that could go wrong went wrong … but to his surprise, Kagami did not mind much, finding it cute how the normally strong male was reduced to a quivering mass.

Needless to say, Sirzechs was overjoyed when she asked for another date and from that day on, their relationship grew only stronger to the point where they finally consumed their love during their wedding. But his greatest joy was when his wife gave him a healthy son, who they named after her deceased brother.

They were truly a great couple and even if Rias was happy for her brother, she always felt jealous … her brother had married the woman he came to love over the last century, but for her, it seemed that fate was not in her favor.

Shaking her thoughts off, Rias eyed her sister-in-law. Kagami was without a doubt a beauty. Her long silky light-brown hair fell down to the mid of her back while two longer hair bangs framed her flawless face and rested on top of her covered bosom. Millicas had his red eyes from his mother, even though hers had a lighter shade. She did not even need much make-up to make her stand out from her peers, only a bit of red lipstick to accentuate her flawless bronzed skin, her fingernails coated in a thin layer of black nail lack. The heiress of the Belmont Clan was dressed in a formal black Yukata, which was kept together by a red slash wrapped around her waist.

Rias could not help but feel jealous sometimes, her sister-in-law being often considered one of the most beautiful female Devils of the Underworld. And many younger Devils envied her relationship with Sirzechs, the two of them already considered the most popular couple in the Underworld.

Letting her cute nephew out of her arms, she watched as he tackled his mother, hugging her legs. Rias eyes became a bit dull as she watched the exchange between parent and child, the loving embrace when Kagami lifted her son up to hold him, her soothing voice when she whispered into his ear, gaining a sweet giggle in return and the proud look on her older brother's face as he told them to finally move to bed.

She closed her eyes. Sometimes it truly hurt seeing them so happy … the sight of a loving husband and wife with their child, the joy of having a person truly love you for whom you are. She wanted their happiness, even though she knew that her chance for actually having a person to love in the near future was nearly nonexistent.

Rias bit her bottom lip, trying not to gain too much attention. She would do everything to have a choice for her future … the choice to marry a person she might come to love.

Sending the family a longing gaze, the crimson-haired princess wondered if there was someone out there who could make her feel special, someone who just saw her as Rias … only Rias.

Only time would tell.

The city of Kuoh, Outskirts, Japan

Hot steam filled the spacious, luxurious bathroom as the glass door to the shower silently opened. A tall blond man stepped out, covered in countless drops of water that dripped down his athletic built. Sighing pleasantly, he quickly pulled a towel out of the wooden shelf to his left and dried his hair off. Wrapping the towel around his waist, the blond man moved towards the sink and gazed at the mirror right in front of him.

He sighed melancholy as he eyed his appearance.

´So much has changed these past decades. Damn, I've truly gotten old, even though only mentally … all the pain and losses I was forced to endure, I can hardly even remember my old life, remember her.´ Carefully, the man touched a nasty looking scar, which went straight through his left eye, degrading the otherwise handsome face. He winced as the memories came back.

But what stood out most was the huge scar, which covered most of his upper chest, making it appear that something had tried to rip him to shreds. Even though his healing factor was still exceptional and had gotten even stronger, he did not allow the ugly scar to heal.

It was a reminder for him … reminding him of his failure. His failure to protect his family.

Naruto took a deep breath before he steeled himself and left the stuffy bathroom. Entering his spacious bedroom, he walked straight to the large table next to his broad bed. Licking his dry lips, he eyed the countless liquors, which he kept on the desk before grabbing a bottle of brandy and poured some of the cold liquid into a glass, followed by two ice cubes.

Shaking his head, he took hold of the glass and stopped in front of the large window, gazing hollowly at the beautiful sundown that transpired outside his home. The late hour still sent some rays of sun into his bedchamber, casting wide shadows over the floor and walls.

´Beautiful, majestic … and yet so deadly at the same time, nature has sure given us such beauty to feast our sight on. A shame humans tend to ignore the wonders of nature, being more concerned with their pointless tasks … such a shame indeed.´ Taking a good gulp of the brandy, Naruto clicked his tongue, enjoying the cold liquor flowing down his throat.

´This world … is not ready yet.´

Pouring the last of his drink down his throat, he sat on the bed edge, putting the glass back down on the counter. His eyes became dull, the eyes of a hardened warrior who had seen much in his life … too much, having seen the good of life, but more so … the gruesome side of life, things he would never forget and still haunted him even in his deepest dreams, never allowing him to completely forget them.

´It will not be the same here, not as long as I still live … too much lies at stake this time!´

The blond-haired man did not show any signs of surprise when the door to his private chamber opened and someone stepped inside before gently closing it once more. He could hear the soft sound of clothing falling to the wooden floor and only seconds later did the bed slightly shake as the person crawled onto it.

A small smile found its way on his lips as two slender yet strong arms wrapped around his neck, pulling the rest of a warm naked body against his back. Naruto now smiled in content as he felt two soft pillows press against his back while the owner's head rested on his right shoulder, her warm breath tickling his ear and cheek, letting pleasant sensations run through his body.

His right hand came up to caress her smooth arms. "May I presume that the mission I gave you was a success?" Naruto, in fact, did not even need to voice his question, as he knew that the woman was very eager and followed his orders without complains.

She had never failed him since he first met her all those years ago. Not once.

The woman nodded slightly, pressing herself harder against his back. "Of course, Naruto-kun. It took me a bit longer than I predicted, but in the end, it was quite easy to gain possession, though it came to a little … bloodshed. I hope this will not be a problem for us." Her soft and loving voice was like music to his ears, her warm embrace giving him the hope and comfort he needed.

His eyes became more determined.

Yes … this was the path he needed to take.

"I see, nothing to fear my dear. I never expected you to gain possession of the stone unnoticed … now that I think about it, he might have been more suitable to get it, but hellas, I already gave him another mission." Naruto closed his eyes while continuing to rub her arms. "Did you kill all witnesses?"

The woman nodded. "I did, although I wasn't able to completely erase all traces of my Ice Magic … that may become a problem in the future, even though the only one they know who can use this form of magic is Leviathan Serafall, one of the Yondai Maou."

"It's not much of a problem then. The Underworld does not know of your existence yet, as they presume you had died long ago … it should remain so, at least for the time being."

"Our Intel was correct after all, your informant did a good job … surely the information was not easy to gather."

"Mmh, he is the best spy I ever met. He may have been a damn opponent in my previous life, but now … it would be much more difficult to gather the pieces without him, but enough of that. Let me see it!"

The woman did not answer. She only stretched her left arm out. Naruto took the clue and stretched his own free hand out. A small, but heavy object fell into his open hand palm.

The former Jinchuriki brought the piece closer to his face, scrutinizing it with his powerful eyes. It seemed like a simple unimportant polished stone, not bigger than his palm. The jewel was in a deep green color and even though it had been long since forgotten and sealed away, he could still feel the power within it.

The number three was engraved into the jewel.

"Yes! A step closer to our goal. You did well, as expected … you never disappoint me."

The woman sighed happily, tightening her embrace, her face nuzzled into the golden shining mop of hair, taking in his scent. "What will we do now? Surely our presence will be noticed by the Three Factions with my actions last night. They may not exactly know who did it, but now they will actually try to search for the responsible … someone who can break into their facility nearly unnoticed is a risk, a risk they will not leave uninvestigated … soon they will come for us."

Naruto hummed softly. "Let them be. They still don't know of us, they aren't even able to sense our presences, so they are of no concern to me … a far greater threat will soon arrive in this world. Very soon so … the pieces are starting to move."

The two gazed at the last rays of sunshine.

"Yes, we need to prepare ourselves. This world won't be ready to fight this war, no … the slaughter that will undoubtfully swallow these lands. None of them has what it takes to stop the imminent invasion … we are their only defense, although a weak one."

"Is there no hope?"

Her question made him pause. It was the same question she had voiced … when he was still a human. When he still felt human, a long time ago … too long ago. He did not have an answer back then. His world had ended in less than a week.

But now he had one.

"No, there is. As long as we stand and fight for this world, for our future … for all the people that had to suffer, we will fight the darkness that threatens to swallow and corrupt this world. I won't let it repeat itself, I won't let their deaths be in vain, not as long as I still have some fighting spirit left in me ... you taught me that after all, huh? You were the one who gave me back my will to fight, to live I should say."

The woman smiled. She always did when she saw a fraction of his true self … she loved the man he had become, or the man he had always been. He still fought despite all the destruction that had happened to him and his world. He was a true fighter, a beacon of hope for this world, even though the humans and other races will never know of this. He was a person she never thought would come across her … and yet here she was. She was probably the only person who truly knew him, she wanted him … she desired him more than anything else and she would have him. No matter the cost or who would dare to stand in her way, his heart would always be hers.

A father to her children should this world still live after the war.

She smiled even wider as she listened to his strong heartbeat. She loved the sound of his heartbeat, as it always made her feel at peace.

"The remaining gems are still needed…."

She only nodded. He chuckled weakly. "What would I be if not for you?"

Her delicate hand came up and grasped his chin, gently turning his head to face her.

Royal silver hair like he had only seen it on one person always managed to catch his attention and made him breathless with admiration. Even though the sun had already disappeared beyond the horizon, her hair was still shining and casted some light across his bedchamber. Her matching beautiful silver eyes gazed lovingly into his very own pair while her beautiful flawless face glowed brightly. Her red-coated full lips formed into a pretty smile, always managing to give him the happiness and the warmth he needed.

Yes, she was definitely one of a kind. He would not let anyone have her.

She was his for all eternity.

"I think we both know what the answer would be, do we not Naruto-kun?"

He chuckled warmly, his right hand travelling through her long beautiful and silky hair, bringing her head even closer to his. She did not resist, her seductive smile never leaving her delicate lips.

"I would still be sulking and pitying myself! Yes … I would still be a nervous wreck if not for you, if not for your love and belief … I wouldn't know what I had become, only an empty shell living without a purpose I suppose."

She hummed softly, already feeling his warm breath on her lips.

"We still have much to do ... this is only the beginning, our greatest challenge has yet to reveal itself."

"True" She carefully traced down his whisker marks, enjoying how he slightly leaned into her soft touch. "We are few in numbers and each one of the Three Factions, as well as the humans and Youkais, will see us as threat. We are alone against this world and the looming darkness, Naruto-kun."

The blond man briefly closed his eyes, enjoying the loving touch of his woman before he gazed at her, his beautiful and mysterious eyes, eyes capable of controlling life, which were filled with pure determination.

"Alone you say, that may be true, but far more powerful we are. They are nothing compared to us … they can view us as threat for all I care, nothing that we couldn't handle because in the end, they are meaningless ... yet still, I would prefer if they would see things our way when the time comes. It would mean nothing to protect this world if its inhabitants could not see what the real threat is."

The silver-haired beauty gave him the most radiant smile he had ever seen. It made his heart beat even faster.

He smiled in response. Leaning forwards, he planted a soft kiss on her supple lips.

The woman moaned into the kiss, parting her lips to suck on his bottom lip.

But Naruto quickly broke the contact, smirking as she frowned in response.

"You seem quite eager, neh … my Grayfia dear." The now named Grayfia hummed softly before she pulled his head closer, their lips once more meeting in a soft yet passionate kiss.

He could allow himself to enjoy this one moment of peace and happiness.

The time was closing up.

A looming darkness was nearing this world.

It was only a matter of time before the first shadows would try to pry their way into this world.

Although, a part of him feared that they might already made contact with some residents.

Somewhere far away, in a desolate place in the Underworld.

A cold wind blew through the decayed halls of a long since forgotten castle, which was build inside the very root of the mountain. No one knew of this former castle, being one of the private refuges of the original Lucifer. No Devil knew of its location any more.

Except for one.

A lone figure walked leisurely across the once proud and luxurious hallway to the throne, one of the very few pieces of furniture that still stood inside the castle.

"This brings back some memories … never thought this place would be forgotten, such a shame indeed."

The cold voice of the man resounded across the deserted hall.

He was a very tall individual, dressed in silver formal clothes that resembled the Satans one's, his shoulders protected by well-crafted armor. The man had a handsome face: his shoulder-length silver hair and a matching goat beard completed his appearance. His golden colored eyes landed on the throne.

A single dark-colored sphere was embedded into the stone throne.

A smirk graced his lips while he approached his destination, finally stopping in front of the throne.

"This is where you wanted me to come, huh? I wonder…."

Carefully, the man's right hand slid over the smooth surface of the sphere.

"What is it you truly want?"

The moment the words left his lips, the sphere lightened up, illuminating the dark hallway in a purple-red light. The silver-haired man gritted his teeth, sweat poured down his face while his body shook uncontrollably.

He could not take his hand off the sphere. He was not allowed to.

His eyes widened when a powerful presence washed over him. Something he had never felt in his long-lived life … something that made even his power pale in comparison.

A lone dark voice resounded inside his mind. A voice that filled him with despair and fear.

´So you have come, little Devil … you've heard the call of my voice … the call for immeasurable power and knowledge.´

The silver-haired man trashed violently, trying to tear his hand off to severe the connection, which grew stronger with each passing second.

´Your world is bound to be burned down to the ground, ready to be consumed by our immense hunger and greed for power… only chaos and death shall remain.´

A pained scream escaped the man´s lips as his mind was slowly corrupted and deceived.

´A portal needs to be opened … to gain access to your world … I choose you to do so. Open a portal for my army and you will be rewarded with immeasurable power, beyond anything you've ever dreamed possible…."

His screams finally stopped to resound across the hallway. The man took a deep breath before a dark smile formed on his lips.

´Do not fail me … be successful on the other hand and I will grant you a place among my Legion.´

"Y-yes, my master … your wish shall be fulfilled!"

The sphere glowed one last time.

The Deceiver had made his first move.

And here you have the first Chapter of my new story. I hope you liked it and that it was to your liking. Now I do not know when I can update the next Chapter as I have much to do in real life and this is also more of a side story and not my main (which will have the first Chapters revised due to spelling mistakes and so on). So I cannot really give you an exact date when you can expect the second Chapter, just look on my profile where I keep you updated of the current process.

In fact, the only reason I managed to bring this Chapter out was because I wrote nearly half of this Chapter on one evening (which is pretty good for me considering my usual word amount is only about 1 k words per day when I have the time).

Author´s Note:

Some information to make things clear.

Firstly, I don´t know the whole story of Highschool DxD. I just know the Anime and the information I read on the Wiki. I haven´t yet read the Light Novels, even though I would like to. Is it possible to read them online or must one buy the Novels? So even if I don´t know the whole content and characters, I will still try to follow Canon a bit, mostly the first five to six volumes, although I will use many new scenes to make it my own story. And because this is more of a side project, the time when I reach the meeting of the Three Factions, the third season will most likely be out already. As I don´t know that much about the characters (mostly those introduced after volume six), I´m thankful for all corrections if you found something off.

Secondly, this is a Crossover between the Naruto Universe, the Fairy Tail Universe and the Highschool DxD Universe, where the actual story will take place. There will be just flashbacks and some characters from the two first Animes as these two worlds have already been destroyed. There will be quite an amount of Fairy Tail characters involved while only three Naruto characters will play a major role, Naruto of course being the main protagonist. Most of his past will be explained during flashbacks and so on.

Thirdly, Naruto´s character and power. For those who followed my main story, you know that I despise Canon Naruto, I truly do … so much potential wasted! Seriously, why could Kishimoto not make a badass protagonist like Ichigo from Bleach? Even though he isn´t that intelligent, he is still badass and still a funny person (no reason to make him as dump as Naruto to have a good and funny main protagonist). Now I must say, the Naruto in this story will have his Canon past, minus some minor changes, he will have some of his traits but he will be more experienced and gained an actual brain! He won´t have a dark/cold personality like in my main story, but he will still do everything to achieve his goals, even going so far to manipulate others. Don´t wanna say much more, just know that he will be far better than his old Canon past.

And lastly, pairings. For those who read the preview to this story already knew that Grayfia is the main pairing, along a woman from Fairy Tail. Those two will be Naruto´s lovers and just to make things clear, Grayfia did never met Sirzechs during the Civil War. When she came across Naruto, she decided to travel with him because she had no one left of her family. So for the rest of the Underworld, she doesn´t exist anymore. So please no flames of her being paired with Naruto, I mean seriously she is one hell of a woman and has so much potential. Just because in Canon she is married to Sirzechs doesn´t mean we can´t unleash our imagination here on Fanfiction! It´s the same with Kurenai in the Naruto Universe. Writers should write original tales and pairings, not just fucking NarutoxHinata or NarutoxSakura … seriously, there are far too many of them by now, even in Crossovers where you have a chance to do much more original pairings. Why do people even bother to write a Crossover when they still gonna pair Naruto with Hinata? That´s beyond my comprehension.

So the main pairing will be Naruto x Grayfia x Fairy Tail woman (which I guess you already know who it is if you´ve read the short flashback at the beginning). There will be many other women who will develop feelings for him, more so the ones he managed to save from the Fairy Tail Universe. And Naruto won´t be obvious about their feelings, he will make use of them to manipulate them and bind them to him, gaining loyal servants. Although, I don´t know if it will become a real Harem. I´ll make up my mind as the story progresses.

And yes, Kagami Belmont is my own creation, although her powers will be those from the Yondaime Kazekage (and they belong to Kishimoto). I created the Belmont Clan to be one of the remaining 34 Pillars, even though they don´t exist in Canon, but hey … most of the Clans don´t even make an appearance so nothing is lost. Although, I don´t like to include an OC Character into my story because it is always difficult for the readers to picture them (well, at least it is for me and I don´t like to read stories where OCs play a major role … hell now I even feel like a hypocrite … shame on me!).
