A/N: This little number here is something that is a joint effort from myself and Wraith002, who has recently decided to step away from writing for a while. He originally came up with the idea of a Devil May Cry / Harry Potter crossover, an idea that he had passed to me with the intention of making it into something worthy of praise.

I've always been an advent fan of the DMC series, even the remake which diverted from the original plot more than a little, and there are a decent number of stories in this crossover category already that have gained attention. So I decided to help keep my mentor's ideas and work alive while he is out of action for the time being.

For now, though, I'll leave you all to be the judge.

Two thousand years ago, the Earth was a very different place. Demons held dominion over humanity, led by the all powerful lord of the underworld, Mundus.

All seemed lost to the world of man as the Dark Emperor's armies spread across the land like an endless tide, until one day, one of Mundus' greatest Generals felt great sympathy for the beings that were being slaughtered.

The devil known far and wide as Sparda.

With this change of heart, he rose from the soul devouring darkness of the Underworld and began to lay seige to the demon hordes that plagued the Earth. A one devil army against tens of thousands of lower and upper-class demons and devils.

Every swing of Sparda's mighty blade, one that bore his name, spelled the death of another foe. Until Mundus' army was routed back to the dark pit from whence they came. Until all that remained was the Lord of the Underworld himself.

Mundus and his former General fought with great intensity. Their battle shaking the air and ground of both Hell from the ferocity, trying to overpower one another until in the end one had fallen.

The once all powerful Emperor of the Underworld laid at Sparda's feet, the former General victorious.

Fighting his way out of Hell to the Human world through Temen-Ni-Gru, the tower meant to house the portal between Earth and Hell, Sparda used his sword and the blood of a pure maiden to seal that gate to the Underworld. Leaving his own immense power behind in the process in fear of what he would become.

For the next two millennia, Sparda watched over the Human world. Ensuring harmony and peace from any demons that may threaten it. Until one day he met a Human woman named Eva, whose kindness and compassion caused him to fall in love with her.

Years later, the Devil/Human couple were blessed with two boys, twins, Dante and Vergil. The sons of Sparda revealing at a young age that they would take after their father in strength and power despite being half-Devil. Because of this, their father gifted them each with a blade designed by his own hands;

Yamato, a katana powerful enough to cut through anything including the very fabric of the world itself, was gifted to Vergil. And Rebellion, a broadsword infused with great demonic power, was gifted to Dante. Both boys destined for greatness.

Then one day, Sparda suddenly and mysteriously disappeared, leaving his wife Eva to look after their sons. Only for a horde of demons to take her from them as well, leaving Vergil and Dante orphaned.

As time went on, the two sons of Sparda grew and forged their own paths in the world. One on a quest for more power, the other to protect the world from the demons that tore apart their family. Both of them clashing in a fierce rivalry that was unmatched.

Many stories have risen about Sparda and his legacy, but this story is about his youngest descendant. The son of Dante, and how his first mission as a hunter intertwined his destiny with that of a young witch. Causing the weight of the world to fall on both their shoulders.

This is the story of Gabriel Sparda and Hailey Potter. The grandson of the Legendary Dark Knight, and the Girl Who Lived...

Albus Dumbledore sat behind his desk in deep contemplation. Throughout his many years, the aging wizard had experienced and endured many things, and given his position of power in both the British magical government and as headmaster of Hogwarts he had made countless choices that affected many lives.

Some of which that still haunted him to this day.

A handful of such decisions revolved around one girl in particular. Hailey Jade Potter, known throughout their world as the the Girl Who Lived, the only known person to survive the dreaded killing curse and had been responsible for the destruction of the greatest Dark Lord since Gellert Grindelwald, Voldemort, when she was only an infant.

Albus had wished had was able to do more for the poor girl. Her parents James and Lily were the perfect example of what people in their society could aspire to, their deaths had struck a hard blow to everyone who knew them. Forcing the Headmaster to place their child with her only blood relatives for safety from the remaining followers of the same Dark Lord she had ended and anyone hoping to exploit her sudden explosion of fame.

The same relatives who hated magic.

Hailey had been raised ignorant to their world and in a less than ideal place, but there was only so much that he could do with their war having just come to an end and there being so much cleaning up to be done.

When she came to Hogwarts for her first year, Albus was happy to see her adjusting so well. Making friends and learning more about where her parents had come from, she had even become a Seeker for her house Quiddich team like her father had long ago.

However, with the good there was also the bad. The young witch having to face a mountain troll to save one of her friends, then going up against a Professor possessed by Voldemort which nearly cost her her life.

Her second year wasn't any less treacherous. The fabled Chamber of Secrets hidden beneath the school had been opened and students were being petrified by the Basilisk that had been there since the original founders. Hailey, being the courageous girl that she was, ventured into the chamber and slayed the beast, even managing to save the poor girl who had been possessed once again by the Dark Lord himself.

It didn't take a man of his advanced age to see a pattern. Each time Hailey came to Hogwarts her life had been put into grave danger, and this year wasn't looking to be any different given the events of the last two days and the knowledge he had obtained.

Beside him, his familiar Fawkes trilled softly. The Phoenix sensing his distress and offering a soft note to calm him.

"I appreciate the sentiment, old friend." Albus said to the mystical bird, petting his feathers softly. His eyes trailing to the issue of the Daily Prophet he had gotten that morning with the caption "Sirius Black Escapes from Azkaban!" displayed on the front page.

The man responsible for the deaths of Hailey's parents and a dozen innocent muggles in the name of Voldemort had escaped from prison. And the biggest concern was him targeting the girl for revenge. Naturally, the safety of both her and the other students was the main point at the meeting with the Minister and the many heads of families making up their government. Albus pressed to have Auror presence on Hogwarts grounds, but the Minister instead issued to have Dementors from Azkaban guarding the school.

Dementors, vile creatures that suck the very happiness from the air and spreads nearly heart stopping cold with their presence alone. Whose kiss takes the soul from their victims leaving an empty husk.

And the Minister was allowing them to be free to roam the same grounds as children between the ages of 11 and 17? The Headmaster couldn't understand the man's reasoning in the slightest for such a decision.

Despite his position of power in the government, Albus couldn't overturn the ruling. But at the same time he was also coming up with plans of his own.

He did not trust the Dementors to keep his school and students safe, if they couldn't keep Black from escaping prison then the chances of them stopping him from getting into Hogwarts was also unlikely.

But he needed to play this safe, not wanting to draw too much attention from questionable parties in high places. Several in the school board were in agreement with him and he had their support along with most of his staff, and he had only so much time to get everything in order.

Standing from his desk, Albus approached a small bookshelf in the far corner of his office. Taking out his wand, he tapped a line books in a particular pattern and caused them to slide backwards and split apart, revealing a hidden compartment within with an old rotary telephone stashed inside.

Technology didn't usually work on Hogwarts grounds, given that magic and muggle technology didn't go well together. But this phone was unique, enchanted to make a call to one place and was only used when the situation needed it.

And right now seemed like a good time.

Picking up the receiver, Albus spun the dial on the old phone. Remembering the number by heart as he punched in the correct order and waited, the line ringing a couple of times before a younger man's voice answered.

"Devil May Cry."

"Devil's never cry." the Headmaster said back. The line was quiet for several moments before the one on the other end chuckled.

"Been a while, old timer. Can barely remember the last time you used that password."

"Indeed, but this is a most severe circumstance. I need to speak with you in person, if you are available."

"I'm at the office right now, business is a little slow at the moment."

Albus nodded to himself, "I will be there shortly." he hung up the phone and turned to Fawkes, "Do you feel up for a trip, Fawkes?"

The phoenix nodded before spreading his wings and flying to the old wizard's shoulder before they both vanished in a burst of flames.

A moment later, the Headmaster and his familiar appeared on a quiet street infront of an old building. Above the wooden double doors leading inside was a neon sign glowing purple that read 'Devil May Cry'.

Fawkes settled himself on Albus' shoulder as he approached the door and stepped inside. The interior, much like the outside, resembled a muggle pub. The floors were wood with pillars supporting an upper level, a staircase in the far left corner with a small lounge set up beneath it, complete with worn armchairs, couch, coffee and pool tables and an old jukebox. Various instruments were set up on a small stage across from it.

Directly infront of the entrance on the other side of the main floor was a desk that looked to have seen better days, and seated behind it was a man a little over a third of the Headmaster's age with snow-white hair, blue eyes and dressed completely in red and black leather with his feet propped up on the surface before him.

The wall behind the man was by far the most attention catching. The surface being covered in skulls and masks belonging to various creatures that skulked in the shadows, pinned there by various knives and swords like decorations or trophies.

"I see the flaming chicken is still your mode of transportation." the man said, tossing the phone he had still been holding to the side where it landed perfectly on its cradle.

Fawkes chirped indignantly at him in response while Albus smiled, "It has certainly been a long time, Dante. I am sorry for the sudden meeting, but I believe this is a discussion best made personally and in private."

Dante lifted his feet off the desk and set them on the floor and motioned to the old splintered chair on the other side. "Then take a load off and lets chat."

The Headmaster approached, taking his wand from the sleeve of his robe and waving it over the chair, turning it into a much more comfortable armchair before sitting down. Fawkes jumping off his shoulder and sitting on the back of it.

"Damn, still wish I could pull that off. This place would certainly look a lot nicer." the half-devil commented offhandedly. "So, what brings you to my neck of the woods?"

"A bit of trouble on my end, I'm afraid." replied Albus before he began explaining what had been happening in the magical world for the last couple of years. Everything that had happened at Hogwarts and how it affected Hailey Potter personally.

Dante listened to every word, his usual laid-back, smart-ass demeanor forgotten and replaced with a rare seriousness. He knew all about the Human magical world, his mother Eva had even been a witch, and he had also known the Potters back when Britain was having their war over a decade ago.

Voldemort had dabbled in various rituals and ended up summoning demons to fight for his twisted cause. Which had drawn the half-devil hunter to their shores to deal with them, which in turn brought him to the company of the local witches and wizards fighting for the side of good.

He'd become fast friends with James Potter and Sirius Black, the three of them hitting up a pub occasionally together. And Lily was a firecracker all on her own and got along well with the red-clad demon hunter.

When the outbreak of demons had been been dealt with, Dante had said his goodbyes and returned to the states...only to hear two weeks later that James and Lily had been killed, and Sirius had been connected to it.

"I don't know what the hell your Minister has been smoking, but it has to be some good shit if he thinks putting those soul-sucking freaks in a school full of kids is a smart idea." Dante said, his voice having a hard edge to it at the man in question's decision.

"Cornellius has never been one to make wise choices when under pressure. I am just regretful that I couldn't have swayed the majority vote." replied Albus. Taking out a small bag filled with lemon drops and popping one into his mouth before offering it to Dante.

The half-devil accepted one of the hard candies, "I doubt you came all this way to keep me up to date. What do you need?" he asked while tossing the sour treat into his own mouth.

"I have many regrets involving Hailey's situation. Wishing I had done more for her after everything she and her parents have done for our world. I cannot with good conscious allow her to be put into another life and death situation. With Sirius' escape, and with Dementors being stationed at Hogwarts, I fear she will not be safe, nor will any of the other students. That is why I am here..."

Dante leaned forward, "So, you need someone to keep an eye on her? I'd be more than willing to do it, hell I know Lady and Trish would want to as well given the circumstances."

"I appreciate that, Dante. Really. But this particular assignment needs to have a bit more discretion. I certainly have faith in the abilities of you and your female compatrons, but having unknown adults wandering the halls of Hogwarts would draw too much attention from questionable parties." replied the Headmaster."

"Okay...what did you have in mind then?" asked Dante.

Albus adjusted his half-moon shaped glasses. "Someone who could keep an eye out for any trouble and offer aid at a moments notice, while at the same time blending in enough to avoid too much suspicion...like a student..." he said, trailing off and causing the half-devil across from him to raise an eyebrow.

Elsewhere, a local school had just let out for the summer. The doors opening and the hundreds of students who had been enduring the seemingly endless lectures and assignments were finally free to enjoy their vacation.

One of said students stood out a little more than a rest. Looking to be 14 and standing a few inches taller than most of his peers, dressed in a pair of ripped jeans, worn combat boots, and a grey wife-beater underneath a black hooded trench coat with red lining.

A head of short, messy black hair and a face with angular features made him stand out more than a little with the female students around him, but his eyes at times caught the most attention.

His right eye a clear, crystal blue, his left a deep crimson. Much like the color of his hair, it was something he had gotten from his mother.

Backpack slung over his shoulder, the teen walked down the path leading out of the school. A couple sets of eyes watching him briefly as he passed groups of students, but he paid them little to no attention, the headphones covering his ears blaring music as he turned down an alley on the familiar trek toward home.

Seemingly unaware of the shadows that started to follow him.

Stopping in the middle of the alley, the teenager glanced over his right shoulder with his blue eye. Hand in his coat pocket pausing his MP3 as the shadows froze in place.

"You're not foolin' any one," he said clearly.

The shadows exploded upward, half a dozen humanoid forms in black tattered robes wielding scythes appearing from the darkness. Their glowing red eyes filled with malice and bloodlust as they came down upon their target and slashed with their deadly weapons.

Smirking, the teen jumped into the air, avoiding the sudden attack while flipping over the creatures and landing on the ground behind them. "So, I take it you guys aren't letting me get home on time today, huh?"

The creatures ripped their scythes from the pavement and turned to face him, spreading out. Three more appeared at the end of the alley he had just come down and blocking off any chance to escape.

"I'll take that as a no." the heterochromic teen muttered, dropping his backpack. Smirking, he reached back into his pocket and restarted his MP3 before he swiped a thumb across his nose and bringing up his fists. "Alright then...Come on!" he challenged as "One for the Money" by Escape the Fate started playing

A chorus of roars filled the alley as the creatures charged forward, closing in around their victim with the intention of tearing him to pieces.

Expecting this, the teen dropped low, bringing his leg up and kicking the closest attacker in the chest. The impact launching it into the air and allowing the youth to snatch its scythe from its weak grasp.

Spinning on the ball of his foot, he swung the weapon around in a wide arc, removing the heads of two of the other creatures before bringing up the shaft to block the strikes from the remaining three. Batting away the other scythes effortlessly and elbowing one of the robed figures in the face hard enough to send it crashing into a cluster of garbage cans, one of the dented lids spinning into the air where the teen spun around and kicked it in the other direction.

The metal projectile bounced off the wall of the alley before ricocheting off the other three creatures, staggering them while their target blocked another scythe strike. Driving the blade of his own into the head of the other trying to get him from behind.

Leaping upward, the teen wrapped his legs around the first creatures neck and spun around. sending it crashing into the side of a dumpster. Flipping back to his feet, he kicked a scythe that had been on the ground behind him, sending the blace piercing through the chest of the creature he had elbowed and pinned it to the wall behind it.

Turning around and facing the last three creatures, the young male held out his hands and gave them the 'come on' motion while the ones he had finished dispatching disappeared into burning particles.

The robed beings roared and charged ahead, scythes raised to slice him to pieces.

Waiting to the last possible moment, the teen ducked and dodged around the deadly blades. Each one getting dangerously close but still missing their target as he weaved in closer and delivered a hard uppercut to one of his attackers. Knocking its head clean off its shoulders and into the air.

Grabbing the scythes of the other two creatures, holding them up out of the way as he swung his leg into one then the other before jumping up and spin kicking them into a wall. Holding his hand out, he caught the falling head of the first of the trio just as the others started to stagger to their feet, with a grin, he tossed the head upward, hitting the fire escape above them and sending the ladder attached to it coming down right on top of them and taking them out.

"That it?" the teen asked, dusting himself off as he looked around the alley for any more enemies. Shaking his head, he walked over to where he dropped his backpack and scooped it up-

A blade suddenly burst out of his chest in a fountain of blood. Another creature having hidden itself during all the fighting catching him by surprise.

Heterochrome eyes looked down at the red stained blade, not in pain or fear, but in frustration. "Dammit! Not again!" he shouted, spinning around and punching the creature in the face and sending it crashing and rolling across the ground.

Reaching over his shoulder, the teen pulled the blade free with a wet 'squelch!' and another splatter of blood. The wounds closing up within moments leaving the holes made through his wife beater and jacket.

"That was my favorite jacket, asshole!" he bellowed, looming over the creature before bringing his leg up and slamming his foot down on its face. The force behind it enough to crack the pavement as it vanished in a burst of burning embers. "Demon scum..."

The teen checked his watch and cursed under his breath, "Late again. Mom's gonna kill me." Without warning he started sprinting toward home at speeds Olympic athletes would envy.

It was just another day in the life of Gabriel Sparda. But he had no way of knowing the events that were about unfold before him in the near future...

A/N: For the record, I am using the DmC version of Dante for Gabriel's likeness with a a couple changes for obvious reasons. And as more time passes, more of his past will open up. But first we need to get him integrated where he needs to be.

Read, review and tell me what you think. I will also start work on updating my other stories as well as soon as I can, just decided to get one last idea out there before fully committing. So for now, all I can ask of you all is patience.
