So this was a story I originally wrote and published back in April, a couple might remember, however I took it down because I wasn't all that confident in it.

That begin said due to a couple requests I received in my inbox asking me to put it back on the site so people could read it, i decided why not. I can't say if I will ever continue it, but even so for those interested I will leave it here, and if I regain my confidence in it I might start it again.

AN: Another story? Why yes, what can I say, I couldn't resist. That being said I am quite excited about this story as I have always loved mythology and a crossover like this gives me a lot of scope to play around with. That being said this is primarily going to be a crossover between Harry Potter and Highschool DxD, with heavy influences from the Percy Jackson verse when it comes to deal with the Greco-Roman Pantheon.

Now this chapter is a tester at the moment but hopefully it turns into a full story.

Hope you all enjoy the chapter and leave a review at the end if you like it.

Disclaimer: I do not own Harry Potter or Highschool DxD, influences of Percy Jackson.

Chapter 1

( - )

(In the Leaky Cauldron, London)

Letting out a slight sigh, Harry Potter leant back in his seat, his arms stretched wide as he let out a wide yawn. He had been sitting here, in the parlour of the Leaky Cauldron for well over an hour now, patiently waiting for his guest to arrive. Not that this bothered Harry too unduly, after all he had used the time well, using it to polish off a splendid steak and kidney pie as well as two pints of stout.

This, in Harry's personal opinion was not that bad a way to while away an afternoon, though a belly full of good food and working his way through two strong glasses of alcohol had understandably made him a little sleepy.

With that in mind Harry finished his stretching and instead looked over to the bar, catching the eye of the landlord, Tom, a lovely old man with a mop of white hair, a toothy smile, a hunched back and a perpetually friendly demeanour.

"Hey Tom, any chance of getting a coffee? Maybe with a nip of fire whiskey in there to give it that little extra kick?" Harry called out as he shifted in his seat, a smile spreading easily across his face.

"Aye, it's not a problem Mr Potter, sir!" Tom replied cheerfully with a bob of his head as he turned around and began to get about making Harry that coffee, thankful to have something to do as his wizarding pub was never particularly busy at three O'clock in the afternoon.

"I told you Tom, call me Harry, just Harry?" Harry called back, rolling his eyes slightly at the overly formal way Tom addressed him.

After all such things had long since become common for Harry. Ever since he had defeated Voldemort nearly sixteen years ago people had been treating him that way, showing him undue levels of respect and awe.

Not that Harry didn't appreciate the sentiment behind it, he and many others had sacrificed an awful lot to bring an end to Voldemort's reign of terror. Dozens of Harry's friends and allies had died both during Voldemort's reign, and after when they had hunted down the last of Voldemort's supporters and backers.

Still that had been over sixteen years ago, and Harry didn't hold any high ranking positon in Britain, hell he was barely ever in Britain. With the only time he ever actually visited being to visit his now teenaged godson Teddy Lupin, and Teddy's guardian Andromeda Tonks, with this usually being on his godson's birthday and at Christmas. That or he occasionally visited Britain to meet up with old friends or his accounts manager at Gringotts.

Of course that being said wizards in general, although by no means a populous race were certainly long-lived, and tended to glorify deeds and events of the past as oppose to looking to the future. It was an issue with their overly nostalgic species, but not one that was about to change anytime soon.

"Thanks Tom." Harry said with a smile as the hunchbacked landlord brought his coffee over, a friendly smile on his face.

"Not at all, Mr Potter, sir." Tom replied with a smile, completely ignoring Harry's previous request. "And can I just say, what an honour it is to have to have the legendary Harry Potter in my pub, a real honour sir."

"Come on Tom, you've known me since I was a kid." Harry said with a slightly tighter smile, a bit uncomfortable now with Tom's enthusiasm.

"I know, I know, I'm just happy to see you back in Britain, Mr Potter." Tom replied, expressing an opinion shared by many wizards in Britain, after all Harry Potter was one of the most important and influential wizards in modern times. Plus his citizenship in Magical Britain was a very large feather in their cap. The wizarding community was less than two hundred thousand worldwide and Britain had been a leading power in this community for the past five thousand years, with this being something that the British wizards were very keen on maintaining.

"Well it's good to be back, my… job keeps me pretty busy, but I always like to come back and visit a couple of times a year." Harry replied, not going into much detail on just what it was he did. British wizard and witches were not just infamous for glorifying the past after all, they were also infamous gossips. There was nothing a British person liked more than a bit of gossip, that and complaining, they loved to complain, especially about the weather.

"Well I'm glad you chose to visit here, so is it business then, or pleasure?" Tom asked as he pulled out his wand and began to levitate Harry's used glasses and plates, magically cleaning them before sending them back to where they were stored.

"Business I'm afraid." Harry replied with a shrug, "I'm supposed to be meeting a… colleague, though unfortunately promptness is obviously not one of his virtues."

"It's just bad manners than is Mr Potter, when one makes a date they should keep to it." Tom said, shaking his head in disapproval, not at all impressed by Harry's guest's tardiness.

"That they should, but this chap is most likely a bit set in his ways, you know how it is." Harry replied with a shrug as he picked up his coffee and took a sip, delighting in the kick he got from the fire whiskey.

Before anymore could be said, they were interrupted by the sound of the door opening.

Seeing this Tom turned around a crooked smile on his face, only for the expression to freeze as he took in the appearance of the striking and intimidating man now entering his pub.

The man was tall, nearly seven foot, with broad powerfully built shoulder, and long, wild shoulder length black hair. The man's skin was so pale that he could almost pass as a vampire, and with his distinctly pointed ears and burning red eyes the resemblance was becoming more and more likely. Of course with it being the middle of the afternoon on a hot sunny day, Tom's fears of the man's vampiric origins were assuaged. Still the man didn't look human, he was too tall, his features too perfect.

Currently the man was wearing a black muggle suit, with a simple white cuff linked shirt and a dark black tie and a pair of highly polished shoes. In contrast to his guest, the youthful looking Harry Potter looked distinctly normal.

With Harry being only six foot tall, with a slight build, thin but not skinny, and wearing a smart set of tailored grey robes. He had short black hair, that was somehow still messy, and which showed off the by now very faded famous lightning bolt scar on his forehead. As well as that, Harry had a slightly stubbly beard and his infamous emerald green eyes which nowadays were no longer hidden behind a pair of glasses, though they seemed to glimmer with a lot more power and wisdom than they did when he was a teenager.

In fact the only unusual thing about Harry was his youthful looks, as even for a wizard he looked young for his age. The man by now was in his early thirties, yet he still looked to be in his late teens. Now wizards were a long lived race, with many of them living to the age of two hundred or older, with this of course meaning that they aged slower than humans. Harry's youthfulness though was a bit exceptional, though considering this was a man who had survived not one but two killing curse, being exceptional was not that surprising.

"Thank you Tom. That should be all." Harry spoke up as he took another sip of his coffee before putting his cup down on the table, his gaze flickering to Tom for a moment and catching the other man's eyes.

"As you say Mr Potter, as you say. Though if you and your… guest… need anything I will be at the bar." Tom replied, a bit thankful that he didn't have to interact with the other man. After all Tom wouldn't say he was prejudice, he was as accepting of other magical creatures and beings as the majority of people, but something about this man put Tom on edge. It might be his eyes, which looked far too old or it could be his inhuman appearance, or just the presence of power and authority he emitted, either way it made Tom uncomfortable. It gave him chills just being in the presence of this man.

Looking away from Tom, Harry instead looked over at his guest, his expression not changing as the other man approached him. A barely hidden look of distaste and disgust on the pale man's face as he looked around the small rustic pub and the handful of wizard and witches in it.

Coming closer to the table, the man then looked Harry up and down, the look of barely hidden distaste not fading as he stiffly took the seat opposite Harry.

"Kokabiel, you're looking well, how are things?" Harry said airily as he raised his hand, within which was now a long thin wand, a particularly infamous one that was made of Elder. Harry's expression not changing as with a few nonchalant flicks of his wrist he cast a few quick and useful wards adding a few more safeguards to the temporary wards that he had already setup, with these ones stopping anyone from trying to listen into Harry's conversation, as opposed to just those Harry was aware of.

"I am not here for idle chitchat Potter." The now named Kokabiel said coldly, his expression not changing for a moment as he gave Harry a look of barely hidden distain.

"Well where I'm from this is how we start conversations. You know, I say hello, then you respond with your own greetings after which there are a few meaningless platitudes about how you are, how you've been etc. Or are things like manners and propriety lost on Fallen Angels…?" Harry said in a friendly tone as he picked up his cup of coffee and took another sip, not at all concerned about annoying the powerful Fallen Angel that was now sat before him, or at least giving him a few snide digs here and there.

In response Kokabiel's expression hardened and his posture stiffened, the aura of power emanating off of him suddenly taking a dangerous turn. "As I said before Potter, I did not come here to exchange quips with you, I am here to do business. My time after all is valuable, and unlike you I have important things that need my attention."

Harry had to force back a smirk as he heard that, forcibly holding back a sharp retort about just what a Fallen Angel may or may not do with their spare time. After all Kokabiel was a ten winged Fallen Angel, a child of the Biblical god and was once one of his most dangerous warriors. If Harry provoked him too much then the Fallen Angel might lose his temper, which could lead to a small part of London being wiped off the map.

"Very well then, let's get down to business." Harry replied easily, once again placing his coffee on the table and giving Kokabiel a curious, searching look. "So I've been told that you have proposed a deal with Lady Ophis for both yourself and your followers to join the Khaos Brigade, in return for which we are to acquire a few items for you, along with the Khaos Brigade lending you some support in your future endeavours?"

Kokabiel nodded his head at that, his demeanour still a bit stiff as he looked at Harry. "Indeed, that is what was agreed."

Harry hummed as he heard that. "Well I am the one who was assigned to oversee the Khaos Brigade's part of the deal. So what exactly are you after?"

Kokabiel paused as he heard that, giving Harry a calculating look. "So the vaunted Master of Death will be serving me will he?"

Harry's smile tightened as he heard that. "No, I will be working with you, a consultant so to speak, nothing more."

A mocking smile spread across Kokabiel's face as he heard that, before he shrugged. "Call it what you want, it matters not."

Harry gave Kokabiel a bored look before replying. "So you were about to tell me what you were after."

"Tell me Potter, have you ever heard of Excalibur?" Kokabiel replied after a moment.

"The sword of King Arthur? The one that was forged by the Fae and blessed byGod before being delivered to the Warrior King by Merlin. Yes… I'm know of it." Harry replied a note of curiousity in his voice now, as he wondered where Kokabiel was going with this. After all that blade had been shattered, with its fragments being re-forged into seven other blades, with each of these blades being a pale imitation of the original. "Though last I heard it was broken."

Kokabiel nodded at that. "Yes and seven other blades were made from its remains. Five of these blades are in the hands of the Church, with two of these swords being heavily guarded in the vaults beneath the Vatican, whilst the others are being protected in similar vaults in Notre Dame in Paris, Canterbury Cathedral in Canterbury, and Saint Paul's Cathedral in London."

"And I take it you want me to acquire these swords?" Harry asked, not mentioning the other two as he already knew where those were, as one was in the keeping of another member of the Khaos Brigade, whilst the other was locked up in the Department of Mysterious, where it had been for centuries now. Not that Kokabiel likely knew that.

"The ones at the Vatican would not be possible for you to get, as the vaults there are protected by more than just mortals, but by Angels as well. The other three however, they are the ones I want you to get for me." Kokabiel replied, a slightly patronising tone to his voice as he judged Harry's capabilities against an angels and found him wanting.

Not that this bothered Harry, as he was comfortable enough in his own skin to not allow the words of some puffed up Pidgeon to get to him. "Well then, that should be doable. Though I am curious, why do you need my help in this, or are you and your minions unable to do this yourselves?"

Kokabiel's eyes flashed with irritation as he heard this. "The Church's paltry defences mean nothing to me, I could break them with just a thought. The reason I am sending you Potter, is because I don't want the thefts linked back to the Fallen Angels."

"Oh, and just why is that?" Harry asked curiously as he leaned forwards in his seat.

"When you have the swords you are to bring them to me, I will be in mountains around Kuoh Town in Japan, assembling my army." Kokabiel replied, his tone brooking no negotiation.

"Japan… you want me to hike all the way to Japan like some glorified delivery boy" Harry said blandly, not that bothered by the request as he had been out that way a few times before and had several identified apparition points he could use. Not that he would accept it easily, after all it was the principal of the matter.

"Yes, you will do as you are told. After all Ophis commanded that you will serve me, and this is what you shall do." Kokabiel replied back mockingly, the sneer on his face a work of art, and one that would put anything Severus Snape was able to do to shame.

"Again I'm working with you, not for you, try to remember that." Harry said mildly, before a slight smirk spread across his face as he suddenly remembered something he had heard. Something that was relevant to Japan, or more precisely Kuoh. "Though now I think about it, isn't Kuoh under the jurisdiction of the Devil faction. Or to be more precise the governorship of two high profile Devil Heiresses?"

Kokabiel's face became stoic as he heard that.

"Yes, Rias Gremory and Sona Sitri if I remember rightly. Two Heiress to two Pillar Clans, as well as the younger sisters of two of the Maou, the leaders of the Devil race…" Harry continued, his smile becoming almost feral as he saw the flicker of discomfort momentarily pass across Kokabiel's face. The ancient being not being able to maintain a straight face like he no doubt wanted.

"That is none of your concern." Kokabiel replied stiffly.

Harry hummed at that, his mind already coming to a conclusion on just what Kokabiel might be up to. "You want to start a new war don't you, another Great War between your three factions? More than that though you want to use the three Holy Swords that I'm to acquire, to implicate the Church as the responsible party?"

Kokabiel's red eyes fixed on Harry as he heard that. "What I choose to do, does not concern you Potter."

"That is true, what you do in your own time is no concern of mine. Though it has made me curious. Just why did you choose to join the Khaos Brigade Kokabiel? I mean you lead an army of nearly twenty thousand Fallen Angels and hold a high status in your faction." Harry decided to press, genuine curiousity rising up in him this time. "Why would you of all people join, what on earth would you be after?"

The Fallen Angel opposite him paused as he heard that, not outright refusing to answer as he instead just gave Harry an evaluating look. "My reasons for joining are simple, I wish to bring order to this world and strengthen my people."

"By starting a war that could wipe all three factions out?" Harry replied as he leant back in his seat as he saw Kokabiel's expression, hiding a smile as he found a chink in the Fallen Angel's armour.

Kokabiel scowled as he heard that.

"Every year that passes the forces of Heaven diminish and decline. Whilst the legions of the Fallen stagnate, with Azazel being more interested in experimenting with his pet humans than leading us. The Devils on the other hand are getting stronger, with their Evil Piece system their numbers are increasing rapidly every year, and with their leaders, those like Sirzechs Lucifer and Serafall Leviathan their faction is gaining in strength and influence." Kokabiel began, his voice low but gaining in strength as his passion was stirred.

"So for that you would break the hard won truce between your three factions?" Harry questioned a slight frown on his own face. As although he had dealt with Devils before, their kind mostly stuck to the Underworld, with their only being a few places in the far east where they had begun to encroach on earth. This though was mainly due to the strength of the Church in the west and the presence of the powerful wizarding community, which although small was mostly focused within Europe with their being a few smaller communities in North and South America, Australia and Africa.

"The truce will be broken sooner or later. I believe it is best to restart the war now, when both the Fallen and the Heavens have a chance of victory than in years from now when we will be just a remnant of our former strength. It is best we wipe out the Devils whilst we can." Kokabiel replied fiercely, his passion once again rising.

Harry made to speak at this point, before he could though Kokabiel cut him off.

"And if we fall or fail to act who will then stand against the foul Devils? The Youaki? Those beasts are more likely to fall in line with the demons than fight them. The other Pantheons? The Pagan Gods of old are no doubt declining just as we are, those greedy beings would not want to risk losing themselves and so will not confront the Devil threat until too late." Kokabiel snarled out his anger rising as he spoke and vented his fury.

Harry made to speak again, but once again Kokabiel didn't give him a chance.

"Maybe the humans then? As if those paltry savages would be able to resist the lure of the Devil's power, no they would fold more quickly than the beasts and fall in line. Then who would that leave, you heretical wizards? Your foul race is barely above the humans, no you cowards would likely hide behind your wards and protections as you always do. Cowering away like craven as the world around you is overtaken!" Kokabiel panted heavily as he finished, his hands gripping on to the edge of the table as he leant forwards, his eyes boring into Harry. "That Potter is why I have joined the Khaos Brigade, so that when the fighting does start the Fallen have the allies we will need to wipe the Devil scum from existence!"

"Well…" Harry began, his expression caught partway between amusement and surprise. "That's nice…"

Kokabiel snorted at that, leaning back in his chair now as he gave Harry a cold judging look. "I did not expect some mongrel like you to understand."

Harry's expression sharpened as he heard that. "Oh I do understand, however I just think you're a paranoid warmonger, one whose action will only lead to the annihilation of his own people."

If Harry expected Kokabiel to get angry at that, he was to be surprised as the man just sneered. "Think what you want Potter, but when the Devils have been wiped out and order has once again been brought to this world, then you will come to me begging for my forgiveness."

"Somehow I doubt that would ever happen…" Harry replied blandly. "But anyway, not that this conversation isn't delightful, but I have things I need to do."

With that said Harry pushed himself to his feet, with Kokabiel doing the same. The Fallen Angel towering over Harry with his broad powerful shoulders and looming height.

"Before you go Potter, I'm curious about something." Kokabiel spoke up as he looked down at Harry, his blood red eyes fixed on Harry's cool emerald ones.

Cocking his head to the side, Harry gave the Fallen Angel a curious look. "Really now?"

"Yes why did you choose to join the Khaos Brigade?" Kokabiel asked, his tone filled with curiousity.

Harry paused as he heard that, his mind wandering for a second. "Well, I suppose I joined for the most dangerous reason of all."

Kokabiel scowled in confusion as he heard that.

Seeing this look Harry gave him a slight smile, "I joined for the love of a woman…"

AN: So what did you all think? This story will contain a Master of Death Harry who is part of the Khaos Brigade. However this story will not just stick to the Highschool DxD canon storyline but will branch out and explore all the possibilities the merging of these two world bring.

That being said I have definite ideas about what Harry being the Master of Death means in terms of abilities and attributes. So I would like to first say that although Harry will be strong he won't be Godlike nor will he be unbeatable as that just does not appeal to me.

This story will also not be a harem story, as I personally don't want to write a harem story as I believe the vast majority of them substitute character development and emotion for clichés and smut. With their only being very few writers who can pull of a good harem story, of which I am not one of them. I know this is unexpected with a Highschool DxD story but it is just the way I want to go.

So anyway here is the first chapter of this potential story I hope you all enjoyed it, and for those interested I have nearly finished the next chapter for 'The Last King' and 'The Asura'.

Thanks for reading, please leave a review.
