AN: So I was working on my next update for my Percy Jackson/ DC story, Oncoming Storm. But then I got stuck, and instead of writing a lacklustre fight scene between a Lord of Order, Lord of Chaos and Percy, I instead decided to dust off an old story idea and go off on a tangent, and, two hours later here we are, my first attempt at a Percy Jackson/ Highschool DxD story.

Let's hope it's not terrible! Which, after reading through a number of other DxD crossover stories, including one I wrote myself, I suspect may indeed be the case. Still, I'm optimistic, and think, with both of the source materials revolving around mythology that a crossover could work out quite nicely.

Either way, here is an example of how to procrastinate when you're supposed to be updating one of your other stories, I hope you all enjoy it.

Thanks for reading.

Disclaimer: I do not own Percy Jackson or Highschool DxD.

Chapter 1

( - )

(In a random pub in London)

Leaning back in his seat, Percy stretched his arms, a loud yawn escaping his mouth as he shifted about, cracked his neck and then nestled back into his overstuffed armchair.

The merrily crackling fire in front of him gave off a pleasant warmth. It only added to the pub's homey atmosphere. Already he was starting to feel slightly drowsy as he lolled back in his chair, his booted feet resting perilously close to the pub's open fire as he lazily waited for his guest to arrive.

Already, he had been sitting here in the snug of some random British pub for well over an hour now.

Not that relaxing in the warm, cosy establishment bothered him too unduly.

No, he had used his time here well.

Not only had he managed to polish off a rather splendid steak and kidney pie, but he had also managed to put away two rather pleasant pints of stout too.

It was not, in Percy's humble opinion, a bad way to while away a cold, wet Sunday afternoon.

Good food, good beer, no monsters, and no death defying activities.

It was practically paradise.

That said, a belly full of good food and strong alcohol, when coupled with his comfortable chair and the warmth of the fire, had understandably started to make him feel a little sleepy. Which wasn't great, as he was expecting his guest to arrive soon.

Grimacing at that thought, Percy looked over to the bar and caught the eye of the bored looking landlord, Tom.

He was a seemingly lovely old man with a mop of scraggly white hair, a toothy smile and a perpetually friendly demeanour.

"Hey Tom, any chance of getting a coffee? Maybe with a nip of whiskey in there, you know, just to give it that extra little kick?" Percy called out, shifting slightly in his seat as he turned to look at the bartender, an easy smile spreading easily across his face as he saw the elder man perk up slightly at his words.

"Aye, not a problem, not a problem at all sir!" Tom replied with a cheerful bob of his head, even as he quickly turned around and began to start whipping up Percy's order

Percy smiled at this.

Looking around at the establishment, he had suspected the barkeep was just thankful to have something to do, after all the pub was not particularly busy at the moment. In fact, looking around Percy couldn't see a single other person in the pub aside from himself and Tom. It was practically dead.

"I told you Tom, call me Percy," Percy called back, rolling his eyes slightly at the overly formal way Tom addressed him. He'd only met the guy an hour or so ago, and although very pleasant, the guy was also a bit too polite. He was never one for formality, especially not when it came to a guy that was old enough to be his grandad calling him, 'sir'.

Unfortunately, however, such formality had become somewhat of a common thing for him over the last few years. No matter how much he asked them not to, people still acted deferentially to him, even people he had known for years.

For all he knew it was meant with the best of intentions, it still irritated.

It had been happening ever since he and the other members of the 'Seven', had defeated Gaea. Ever since then, people in the divine world had been treating him like some kind of legend.

It was tiring, especially when people he had never come across or met before recognised him and then came wheedling over to suck up to him.

From what he had heard, the other members of the Seven, apart from Jason and Leo, were also getting sick and tired of it too. Especially those that had stuck around the Camps, or New Rome, and thus were more exposed to that bullshit than he was.

Not that all of them had stuck around. Frank and Hazel had both left, from what he knew they had both moved to Canada together, to live as man and wife, some five years ago now. Which was honestly something Percy wished them well with, they were good people after all, and they both deserved a happy ever after.

Likewise Leo had also left the camp. The irritating child of Hephaestus, now a grown man, worked and lived in Italy with his long-time girlfriend -some mortal girl whose name he couldn't remember. What he could remember, however, was that the son of Hephaestus was now overseeing one of his father's spare forges, the one which was based inside Mount Vesuvius. While his girlfriend meanwhile tended to their vineyard on the slopes of the 'dormant' volcano and made pretty decent wine. It was all pretty idyllic really.

Either way the guy was living a good life.

All of them were, really.

Then again they deserved it, especially after all they had been through.

Perhaps more so those that had been involved in the defeat of Kronos and his Titan army, as well the defeat of Gaea, after all they had got double whammy of war, heartbreak and tragedy. He was one of that number, one of the ones that had fought in both the Titanomachy and Gigantomachy.

Unlike the others, however, who had got out of the life as soon as they could. He had stuck around, and had continued to go on quests for a number of years after the wars. For a while he had even worked for Olympus and the gods as their enforcer for a time too. During which he had hunted down scores of rogue monsters and demigods, and dealt with incursions by other Pantheons into the Olympian's territory. It had been a bloody, but rewarding job, for a time. But still, like with all things the shine had soon worn off.

In contrast, Jason and Piper were both happily living together in New Rome. Not long after the war they had both decided to retire from active service, and nowadays were just mentoring the next generation of demigods, and preparing them for what awaited them in the real world.

Annabeth meanwhile was working as an Architect in Los Angeles for the rich and famous, and, from what he had heard, was currently engaged to a movie star, and an annoyingly nice one too.

That was to be expected though, after all his relationship with her had broken down a year or so after the fall of Gaea. It had been amicable enough though, after all they had broken up for no other reason than the fact that they just wanted different things out of life.

He had wanted to remain a part of the supernatural world and to keep going on adventures and meeting and seeing new things. She, meanwhile, had wanted to go to college, have a career in Architecture, and then settle down and have a family.

She had also wanted to cut off ties to the madness that is the supernatural world entirely, and to enable that she had even asked for her 'demigod scent' to be removed by Hecate as a reward for defeating Gaia.

It had been a long time since he had last seen her, and what little he did know about her life now he at least knew she was happy. The same could be said for all the other demigods he had known growing up. Those that survived, and there were not many, had all moved on with their lives. Over the years he had lost contact with many of them, just like he had lost contact with Annabeth.

It was a shame really considering all they had been through together, but then again in life these things happen. Sometimes people grow up, they drift apart, and they realise that they want different things out of life.

Letting out a slight sigh as he realised his mind had started to wander, Percy quickly found himself brought back to the present when a large cup of steaming hot coffee was placed on the table beside him.

At the sight of it, a smile spread across his face as he turned and thanked the aged barkeep. "Thanks, Tom."

"Not at all, sir." Tom replied with a smile and a bob of his head, completely ignoring Percy's previous request. "Just doing my job, besides I'm just glad to have something to do. The place has been oddly quiet today."

"Well it is a Sunday afternoon, I suppose." Percy shrugged good-naturedly, sending Tom a crooked smile as he had a sip of coffee.

It was pretty good coffee, and the generous nip of whiskey Tom had put in it gave it an extra kick. It certainly helped wake him up a little.

"Aye, that's true." Tom nodded. "Though you made it out at least."

"Better than just waiting around in a hotel room. Besides, I've arranged to meet someone here." Percy smiled back, taking another sip of his drink.

"Ah see, I was wondering why an American tourist had just dropped by. I mean this place is pretty far from the centre, it's more of a local's pub than anything. So, if you don't mind me asking, sir? Is it business then that brought you here, or pleasure?" Tom asked, a slight smile playing around his mouth now. A cheeky glint had appeared in his eyes.

"Business I'm afraid." Percy replied with a shrug, "I'm supposed to be meeting a… colleague I supposed you might call him. Though unfortunately, promptness is obviously not one of his virtues..."

"See that's just bad manners that is. When one agrees to meet at a certain time, then they should keep to their commitment. That's just common decency that is." Tom said, shaking his head in disapproval. The older man was clearly not impressed with the tardiness of Percy's guest.

"That they should. But unfortunately this guy is pretty set in his ways. You know how it is." Percy replied, a smile on his face as he picked up his coffee and took another sip, once again delighting in the slight kick he got from the whiskey.

Opening his mouth to continue their conversation, Tom didn't even manage to get another word out before he was interrupted by the sound of the door to the pub opening.

Looking around at the sound, both of them at once saw the newcomer step inside, a wave of cold, wet air proceeding him, even as his bulky frame practically filled the doorway.

Taking another sip of his drink, Percy eyed the other man coldly.

( - )

(With Tom)

Turning away from the pleasant, and surprisingly quiet and soft spoken American, Tom pasted a smile across his face as he turned to face the entrance. It had been an unusually quiet day so far, and he was eager to welcome another paying patron. As he turned around however and fully took in the newcomer, he could feel his smile to freeze in place.

The man was imposingly big, and had a very distinct and striking appearance.

Eyeing the newcomer warily, Tom estimated that the man must be at least seven feet tall. Adding to his height, he also had broad, powerfully built shoulders, and a long, wild, shoulder length, mane of black hair.

Looking at him closely, Tom also noticed that the man's skin was also very pale, so much so that he could almost pass as a vampire, if such a thing existed. Inspecting him further, Tom found this likeness further emphasised when he noticed the man's slightly pointed ears, and the small, round sunglasses he had covering his eyes.

Was this one of those goths, or emo types?

He didn't keep up with popular culture that much nowadays, his clientele was pretty old school. But even so, he had thought those fads had died out years ago?

Or perhaps the man was one of those cosplayer types, and he was dropping into the pub to meet some of his fellow cosplayers?

Honestly, Tom didn't know.

What he did know, however, was that there was something distinctly unnerving and intimidating about this man. He was too tall and his features too perfect and angular. Adding to that, was the fact he was wearing sunglasses inside. What kind of self-respecting person did that?

Strangely at odds with his eccentric appearance, even for London. The man was currently wearing a plain, charcoal black, suit, with a simple white, cuff linked shirt, a thin, dark black tie and a pair of highly polished black shoes. It was like he was dressed for a funeral.

Again, Tom didn't know what to think, except that this was a cosplayer of some sort and those ears of his were either prosthetics, or some kind of expensive cosmetic surgery.

Shifting his head slightly, the newcomer scanned the room for a moment, an inscrutable expression on his face. Only for his expression to change, and for his mouth to set into a thin line as he looked past Tom and focussed on where Percy was sitting, after which he began to approach.

Looking between Percy, and what he assumed was the young man's guest. Tom couldn't help but note how normal looking Percy looked when compared to the other man.

Percy, he could see, was only six or so feet tall, and although he did have broad shoulders, and noticeably muscled arms, like a Rugby player; only more lean than stocky, he was nowhere near as big or as imposing as the other man.

On top of which, unlike the newcomers formal dress, Percy was dressed far more casually. Instead of a suit, he was wearing a slight baggy grey T-shirt, some normal blue jeans, a pair of brown leather boots, and a tan coloured jacket -though admittedly the jacket did have an oddly metallic looking golden, fur lining. For the most part though he was dressed very casually, like a man waiting for a date. The newcomer meanwhile looked like he was in mourning.

Adding to his clothing, was the younger man's appearance too. He had bright, sea green eyes, a slight tan and a bit of a stubbly beard. He also had cropped black hair that was somehow still messy, and which, now he looked at him closer, seemed to also have an odd streak of grey going through it. Though noticeably the grey streak didn't look to be dyed. Instead it looked like something more natural, perhaps a discoloration caused by a birthmark under his hair, or something like that.

All in all though, Percy just looked, for the most part; to be an average, twenty odd year old, well-to-do, run of the mill young man. Not a bad looking chap, but not someone who would stand out in a crowd that much either. He was certainly not as striking and unusual as his guest.

"Ah, it looks like my guest has arrived. Thanks for the chat, Tom, I appreciated the company. But would you mind giving us some privacy?" Percy suddenly spoke up behind him, making Tom start slightly as he tore his gaze away from the newcomer and looked back to the younger man, noting as he did the apologetic look on the younger man's face.

That said, Tom also noticed how Percy's lips had curled upwards in poorly hidden amusement at Tom's reaction to his guest, even as he took another sip of his coffee, before with a roll of his eyes he put his cup down on the table, his green eyes flickering from Tom to his guest.

Seeing this, Tom nodded and put the drinks tray under his arm.

Whoever this man was, Percy clearly wanted to talk to him in private, and honestly, considering the way the man looked, Tom was pretty glad to be getting out of his way.

"Well enjoy the coffee sir. Though if you and your… guest… need anything, I will be at the bar." Tom replied with a bob of his head, inwardly quite thankful that he didn't have to interact with the other man.

Not that Tom was prejudiced, or judgmental, or anything like that.

No, he was pretty accepting of other people and the different ways they dressed and identified themselves. But still, something about this man put him on edge.

It might have been the fact that he still hid his eyes behind sunglasses, despite being indoors. Or it could be his inhuman appearance -there had to have been some cosmetic surgery involved there- no normal person had such angular, perfect features, or long pointed ears like that. That, or it was just the presence of danger and authority the man emitted.

Whatever it was though, something about the man made him uncomfortable. It gave him chills just being in the presence of this man.

Honestly, he didn't envy the friendly, younger lad. He hadn't even spoken to the newcomer yet, and already he wanted to be anywhere but in his presence.

( - )

(With Percy)

Looking away from Tom as he shuffled away, Percy instead looked over at his guest, his expression not changing as the other man approached him.

Smiling coldly, Percy could already see the barely hidden look of distaste and disgust on the taller, pale man's face as he looked around the small rustic pub, his eyes coming to rest on Tom for a moment, before he looked away.

Percy could see from just a glance, the contempt with which the man viewed common mortals. It was one of the reasons he had used the Mist to keep the pub empty. He didn't want his guest losing his temper and putting innocent mortals in danger if he could help it. If that were to happen then he would need to step in, which could very easily lead to a fight starting.

Coming to a stop just in front of where he sat, Percy could see the newcomer looking him up and down. The look of barely hidden distaste on the other man's face was still very much locked in place, even as he proceeded to stiffly take the seat opposite him, his posture still stiff as he took off his sunglasses.

"Kokabiel, you're looking well. How are things?" Percy said airily the moment his guest sat down, his sea green eyes meeting the other man's cruel, burning red eyes head-on.

Raising a hand as he did this, Percy then proceeded to click his fingers once, the sound echoing oddly in the quiet pub. Not that Tom so much as looked in their direction

Then again considering he had just manipulated the Mist, the veil of magic over earth that the Greco-Roman Pantheon used to hide the Divine from the mortals, Percy honestly wasn't surprised.

Nor did Kokabiel look too surprised either. The other Pantheons might take a more reactive approach to common, everyday mortals finding out about the Divine. Mainly by either killing them or wiping their memories. But they still knew about, and appreciated, the Mist, and had, to a lesser extent even learned how to manipulate it in their own ways. Though more often than not, their control of the foreign magic paled in comparison to a user from the Greco-Roman Pantheon.

"I am not here for idle small talk, Jackson." Kokabiel replied coldly. His pale, haughty expression did not change for a moment as he continued to give Percy a look of barely hidden disdain.

Kokabiel, Percy noted, didn't think much of humans, and from Percy's experience and what he had heard the Fallen angel thought even less of demigods, 'the bastard children of 'heretic/ pagan' gods', like him.

"Well, where I'm from this is how we start conversations. You know, I say hello, and then you respond with your own greeting, after which there are a few meaningless platitudes, you know, like about; how you are, how you've been, etc. Or are things like manners and propriety lost on Fallen Angels…?" Percy shot back in a friendly tone, his green eyes narrowing as he picked up his cup of coffee and took another sip.

Outwardly he made sure to show no concern at all about annoying the immensely powerful Fallen Angel that was now sat before him. Despite Kokabiel being a celestial entity that could easily obliterate half of London if he was minded too.

God, Devil, Angel, it didn't matter what someone was, if he could get away with giving an arrogant tool a few snide digs here and there, then he would gladly do it. Within reason of course, his nearly two decades of active experience in the Divine world had at least taught him some common sense.

In response to his words, Kokabiel's expression hardened and his posture noticeably stiffened, the aura of power emanating off of him suddenly taking turn for the dangerous. "As I said before, Jackson. 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 require my attention."

Percy 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 God with a big G's, most dangerous warriors.

On top of which, according to what he had heard and going off what he was seeing now, the guy was a 'Grade A' bell end.

As such, if he provoked him too much, Percy knew that the temperamental Fallen Angel might lose his temper, which in turn could lead to him trying to wipe a greater part of the London Metropolitan Area off the map.

He enjoyed making snide, caustic and sarcastic comments when he could, but he wasn't about to endanger himself and millions of others just to ruffle Kokabiel's feathers a bit. There was a fine line a person needed to walk when it came to mocking top tier mythological entities, one that Percy had had to learn to walk over the years.

"Very well then, let's get down to business." Percy replied easily, once again placing his coffee on the table and giving Kokabiel a curious, searching look as he did so. "So I've been told that you have proposed a deal to Lady Ophis for both yourself, and your followers, your army, 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 some of your future endeavours?"

Kokabiel nodded his head at that, his demeanour still a bit stiff as his red eyes bored into Percy's green ones. "Indeed, that is what was agreed."

Percy hummed in response. "Well, I am the one who was assigned to oversee the Khaos Brigade's part of the deal by Lady Ophis. Unfortunately, Ophis, as wonderful as she is, isn't always that good at passing on the finer details. So although I've been told to sort out the deal with you, I haven't been told exactly what that deal might entail yet. So tell me, what exactly are you after?"

Kokabiel paused as he heard that, his eyes narrowing as he gave Percy a shrewd, calculating look. "So the vaunted 'Watchdog of Olympus', the 'Oncoming Storm', will be serving me, will he?"

Percy's smile tightened as he heard the titles, one an insult created by an annoying enemy deity, the other an embarrassing title made up by Apollo, an annoying allied deity. "No, I will be working with you as 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, either way you will be serving my will."

Percy gave Kokabiel a bored look in response to his provocation, before replying. "So you were about to get to the point, and tell me what you were after?"

Kokabiel's lips curled upwards in dark amusement. "Tell me Jackson, have you ever heard of Excalibur?"

"The sword of King Arthur? The one that was forged by the Fae and blessed by the Biblical God before being delivered to the warrior king by Merlin, or the Lady in the Lake, depending on which version of the legend you believe. Yes… I know of it." Percy replied, a note of curiosity in his voice now as he pondered just what the Fallen Angel was up to. After all, the last he had heard was that the blade had been shattered centuries ago, with its fragments then being re-forged into seven other blades. With each of the seven blades being a pale imitation of the original. "Though last I heard it was broken."

Kokabiel nodded at that. "Yes and seven other Holy Swords were made from its remains. Five of these blades are in the hands of the Church. Two of the Holy Sword are being heavily guarded in the vaults beneath the Vatican, whilst the others are being protected in similar vaults beneath; 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?" Percy asked, deliberately not mentioning the other two, as he did so. After all, he already knew where both of those were.

One of them, he knew, was in the possession of another member of the Khaos Brigade, a descendent of Arthur himself, who was creatively called, Arthur, himself. The other shard, meanwhile, he knew, was locked up and gathering dust in the attic of the Big House, back at Camp Half Blood where it had been for well over a century now. A relic/ trophy of a long since completed, and mostly forgotten, quest. Not that Kokabiel likely knew that.

"The ones at the Vatican would not be possible for you to get. Those vaults are protected by more than just mortals and magic, but by celestial enchantments and 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 Percy's capabilities against an angel, and found him wanting.

Not that Kokabiel's judgement bothered Percy too unduly, he had fought titans, giants, gods and even a primordial god, and had survived. He was comfortable enough in his abilities to not allow the words of some puffed up, prick of a pigeon 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 it yourselves?" A smirk spread across his face as he said this.

In response Kokabiel's eyes flashed with irritation at the taunt. He could feel the air around him suddenly growing heavier in response. "The Church's paltry defences mean nothing to me, I could break them with just a thought. The reason I am sending an expendable pawn like you though, Jackson, is because I don't want the thefts linked back to the Grigori."

"Oh, and just why is that?" Percy asked curiously as he leaned forwards in his seat. Ignoring as he did the potential fallout that could come if the thefts were linked back to him, and thus his old employers, the Olympian Council.

"When you have the swords, you are to bring them to me. I will be in the mountains around Kuoh Town in Japan, assembling my army." Kokabiel continued, ignoring Percy's question as he did so.

From his tone, Percy could already tell Kokabiel was not prepared to negotiate, nor was he in the mood for bantering.

"Japan… you really want me to hike all the way to Japan like some glorified delivery boy, just to drop off a few shiny trinkets?" Percy asked blandly.

Despite his words, however, he was not actually that bothered by the request, as not only had he been out that way a few times before but he also knew a handy, easily bought Pegasus that he could get to give him a lift there for a small bushel of apples.

Not that he was about to accept the request gracefully. It was the principal of the matter. He had to at least moan a little about the extra travel, after all he was not just some common errand boy. Besides, the gods of Olympus at least had the common decency to dress up their errands as 'quests' for demigods, even if that was only to make them feel better about their lot in life.

"Yes, and you will do as you are told. You know as well as I do, Jackson, that Ophis commanded that you fulfil my orders, and this is what I want you to do." Kokabiel replied back mockingly, the sneer on his face a work of art, and one that would put even the nastiest and meanest of the long dead Octavian's sneers to shame.

"Again I'm working with you, not for you, Try to remember that, 'kay." Percy replied 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 that 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 suddenly became noticeably emotionless at Percy's words.

"Yes, Rias Gremory and Sona Sitri, if I remember rightly. Two Heiresswa, to two Pillar Clans, as well as the younger sisters of two of the current Maou', the leaders of the Devil race…" Percy continued, deliberately trailing off at the end, his smile becoming almost feral as he saw the flicker of discomfort momentarily pass across Kokabiel's ageless face.

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

Percy 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 Percy as he heard that. "What I choose to do once I receive the swords, does not concern you, boy. Your job is just to acquire them, and then bring them to me!"

"That is true, what you do in your own time is of no concern of mine. Though it has made me curious. Just why did someone like 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…" Percy decided to press genuine curiosity rising up from within him this time. "Why would you of all people join our group, what on earth are you after?"

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

"By starting a war that could wipe out all three Factions?" Percy replied dryly as he leant back in his seat. His lips twitching upwards as he saw Kokabiel's expression turn colder, it appeared he had found a chink in the Fallen Angel's armour.

Scowling at Percy's words, Kokabiel shifted in his seat, sitting straighter as he did so, his crimson eyes locked on Percy with almost fanatic intensity.

"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 in 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 with ever year that passes." Kokabiel began, his voice low but gaining in strength and passion as he continued to speak.

"So for that, you would break the hard won truce between your three Factions?" Percy questioned a slight frown on his own face. Although he had dealt with Devils trying to poach demigods once or twice before, their kind, from his experience, mostly stuck to their plane of existence, their Underworld. In fact, there were only a few places in the world, predominantly in the Far East, where they had begun to encroach upon, and colonize the earth.

The reasons behind their limited intrusion thus far onto the earth though, was not down to any restraint on their part. But instead mainly due to the strength of the Church in Europe, the Americas, Africa, and Australia; as well as the presence of all the other Pantheons; including the Norse, Greco-Roman, Persian, Hindu, and many others besides. All of whom endlessly squabble for space, control and worshippers.

"The truce will be broken sooner or later. I believe it is best to restart the war now, when both the Grigori and the forces of Heave, have a chance of victory, then 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.

Percy made to speak at this point, before he could, however, 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, like your own? The Pagan Gods of old are declining just as we are. Those greedy beings would not want to risk losing themselves, and so will not confront the Devil threat until it's too late." Kokabiel continued, his lip curling in disgust, and his anger rising as he spoke and vented his fury.

Percy frowned, and made to speak again, however 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 demigods, the abominable by-product of Pagan gods and man? Your foul kind is barely above the humans! No, you cowards would fold, flee and hide, just like the rest! Cowering away like craven as the world around you is overtaken!" Kokabiel panted heavily as he finished, his hands gripping the edge of the table hard enough to crack the wood, as he leant forwards, his eyes boring into Percy. "That Jackson 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…" Percy 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 Percy a cold judging look. "I did not expect some mongrel like you to understand."

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

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

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

With that said Percy pushed himself to his feet, with Kokabiel doing the same. The Fallen Angel towered over Percy.

"Before you go, Jackson, I'm curious about something…" Kokabiel spoke up again as he looked down at Percy, his blood red eyes fixed on Percy's cool sea green ones.

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

"Yes, why did you, you, who are famed for your rapid loyalty to the Olympians, leave them, and instead choose to join the Khaos Brigade?" Kokabiel asked, the slightest hint of curiosity in his tone now too.

Percy paused as he heard that, his mind wandering for a second. "Well, I didn't abandon my family and friends if that is what you are accusing me of, I still care about them and will not raise my sword against them, Lady Ophis knows this. But still, why did I join the Khaos Brigade? Well, I suppose I joined for the most dangerous reason of all…"

Kokabiel scowled in confusion as he heard that.

Seeing this look Percy gave him a slight smile, "I joined for the unattainable, and most likely unrequited, love of a woman…"

AN: So what did you think. Originally I envision this story, when I first had the idea in summer last year, that this story would be a Harry Potter crossover story. Then I got bored with the source material, and gave up. Now however I am trying it using the Percy Jackson series as the crossover material, and I have to say I think it might turn out alright.

This story will contain a fully realised, adult Percy Jackson, not a teenage version, who has chosen to be part of the Khaos Brigade, for reasons. That said, this story if it continues, will not just stick to the Highschool DxD canon storyline, but will instead branch out and explore all the possibilities the merging of these two world bring.

Also if it continues, this story will not be a harem story, as personally I don't want to write a harem story. I've tried it before and it was terrible! Please check it out if you want to cringe, it's on my Seagate account. But no, this won't be a harem, as I believe the vast majority of them substitute character development and emotion for clichés and smut. With their only being very few writers, certainly not me, who can pull of a good harem story. I know this is unexpected with a Highschool DxD story, but honestly it is just the way I want to go. There could be a number of different relaitonships along the way, but there will not be an endgame harem.

Now this chapter is a tester at the moment, but potentially, if the idea passes muster, it could turn into a full story.

So anyway, please check out my other stories if you have the time. I'll be getting back to work on my Oncoming Storm story, and my 'the Last King' story after this. So yeah, hanks for reading, please leave a review.
