Nephilim of Zero

ESKK: here's the first ever DmC: Devil May Cry Familiar of Zero crossover fic. I'm really excited about this fic and hoped all of you will love it and Vincent Hunter Vega if I see you review this fic saying that Nephilim or Angel human hybrids or not to use Dante as a basis for Saito Hell or even try and tell me that I can't take flames kindly and call me a spoiled brat then trust me I'll hit back hard.

Now before we officially begin I would like to say that you all may flame me as long as there's something wrong with my grammar if it's any other reason like you hate Character replacement stories or that you hate the Devil May Cry reboot then get the Hell out of my sight. We are all free to write whatever kind of fanfic we want whether its character replacement or adding more to a current storyline or even two protagonists meeting and joining forces to defeat a common enemy. We are all free to write out fanfics not for glory or love but to give joy to other people and for our own amusement.

And as for the story line everything will go as it was in season 1 but after season 1 we'll be taking a more Devil May Cry route giving you a fair warning now.

Anyway in the words of classic Dante let's rock baby!

(Prologue)

You heard the legend haven't you...? Well let me tell you it again a long time ago there was a race of warriors who were just, true, and noble, there powers were that of legend making them formidable. These people were known as Nephilim children of Angels and Demons. The Kingdoms worshipped the Nephilim as if they were Gods and yet they never accepted the praise only did what was right. But with all their power there were those who feared that power.

The Nobles and Royals of the world saw them as an obstacle in there superiority and sought to annihilate them. Thus Royals all over the world began what is known as the Nephilim Annihilation act. The Nephilim of course with their strength did not take this lying down but the Nobles and the Royals used a Forbidden ritual which crafted for them weapons that can harm a Nephilim. Thus Nephilim were hunted down none were left alive no man woman or child not even the infants were left breathing.

Many Nobles and Commoners sought to save the Nephilim but they were soon deemed traitors stripped of all their belongings and then executed. Many Nephilim had no choice but to give up and hide and pray one day there people would make a comeback. But as the ages went on the Nephilims blood began to thin out leaving behind very few pure blooded Nephilim and in the end the Nephilim would be doomed to extinction. But one day on the day of the Spring summoning festival a young girl commonly known as Louise the Zero was about to be the Messiah who saved the Nephilim from extinction. For within her she carried unimaginable power long thought lost. But can she and other Nobles find redemption for their Ancestors mistakes... we shall see.

(In the human world)

A young boy was fighting with a broad sword that had a dragon like guard. Most would wonder why a 17 year old boy would have such a weapon. Well they should pay close attention to his opponent which so happen to be something of the demonic nature. This boy was known as Saito the Demon Slayer for his sword Alastor carried to power of a mighty dragon and his custom made Gun Royal Flush made him a deadly advisory. He was what most would call a freak an outcast but what he lacked in social standing and brains he made up for in spirit and strength.

As he fought he stabbed the Demon through after all it was his parents wish for him to stay hidden. Saito was an orphan his parents murdered for loving each other. Most would wonder why kill a couple for that well it was because there love was forbidden as he was fathered by a Demon Father and birthed by an Angel Mother making him what is known as a Nephilim.

As he fought he wondered if his mother was watching him from heaven and if his father had ever made it to the other side but he quickly shot that idea down when he saw more demons appear. "Well then let's rock baby!" he yelled before switching Alastor into its Hell mode. Alastor was his father's family heirloom and it was enhanced by his mother specifically for him as the swords Devil mode was that of a weapon that was part Axe and part War hammer.

"Well then Juggernaut lets kick ass," he yelled before he slashed and slammed his opponents easily breaking their defenses. It was then that a large group of fast ones appeared as the boy smirked before switching his weapon to a Scythe that had two blades making it resemble a crescent moon. "Time for an Eclipse," he said before annihilating his opponents.

After they were killed Saito put Alastor back on his back where it disappeared off his back most likely waiting to be called by its master again as he didn't even have to pull out Royal Flush for this battle.

Royal Flush was a custom made Gun that could shoot two bullets at once and thanks to an enchantment it never ran out of ammo. "Man these punks are getting too easy for me," he said as he wondered if he should stay in Japan at all. He IS going to graduate and all the people he knew would be going off to college to prepare for a career. But as far as the Demon King knew Saito didn't exist. "Well nothing else to do now but grab...a... what the hell is that?" he asked as he saw a portal appear in front of him.

(Meanwhile in another world)

A girl with pink hair and a wizard like uniform was beginning her summoning ritual for her familiar as she was known as Louise de La Valliere. She was commonly known as Louise the Zero but that wouldn't stop her from summoning a powerful and majestic familiar to call her own. IT was then that she began to chant as she knew for her families honor and name, she, had to gain a familiar.

She got up with various people whispering and muttering beneath their breaths, but Louise de La Valliere heard them.

"Looks like it's Zero's turn."

"I wonder what's going to blow up this time."

"I'm not sure why she's still here." Were among the few of the more negative comments, some were more neutral in tone, but the girl stepped up to the summoning circle with the elderly teacher mage giving a nod of approval.

"Oh faithful, beautiful, and powerful servant, somewhere within the universe, please heed my come side and answer my summons!" She said and in a flash of light, Saito was there instead of his home. His weapons were sheathed, since he had already finished up the demons and everyone was surprised at the fact that a boy was summoned. Most that completed the summon would receive an animal like a toad, mole, or even something like a Salamander or Wind Drake, but no one had so far summoned a 'normal' boy.

The Normal boy Saito who was currently finishing a milkshake as he looked around bored.

"Wait this can't be right!" Louise yelled as Saito was drinking his milkshake.

"Hah Louise summoned a commoner!" a random student called as Saito checked if he had any milkshake left and found it empty.

"Damn," he cursed as threw the empty paper cup and it so happened to hit the Noble.

"Please let me have a do over!" she begged as she couldn't let this boy be her familiar he was dressed funny as the white and black coat was the only noble thing on him as he had a sleeveless shirt, a pair of baggy jeans, and a pair of heavy duty boots.

"Sorry My Louise but there are no do overs sense the Spring Summoning ritual is a sacred wright. So I'm sorry but you're stuck with Mr..." the professor trailed off as Saito realized he was talking to him.

"Oh Saito the Demon Slayer," Saito said as the peaked everyone's attention.

"Yes well Louise can you finish the contract," the teacher said as she sighed.

She then went to Saito as she looked deep into his eyes. "You should be grateful not many commoners get to enjoy this so don't let it get to your head," Louise said just before she kissed Saito catching him off guard but it was at that moment that he felt a pain on his hand which wasn't hurting much. When she released Saito smirked as Louise had a bad feeling about that smirk.

"Look lady I will enjoy a kiss just as much as the next guy if he's straight but mind telling me or I don't know WHAT THE HELL IS GOING ON AND WHERE THE HELL AM I!" he demanded as Louise was surprised but quickly got angry.

"Don't you talk to your master like that!" she yelled as Saito scoffed.

"Master really?" he asked sarcastically as he wasn't one to follow other orders.

"Yes you're my Familiar and I'm your master so you better start..." she began but saw Saito was walking away. "Wait where are you going!" she demanded as Saito stopped and turned to her.

"Look I'm no one's servant and besides I'm the kind of guy who works alone y'know trust issues, don't play nice with others, lone wolf type of thing," he smart talked before going back to walking away.

"Um, do you even know where you are?" Asked the elderly man, while most of the students started snickering at how Louise failed in a different manner, instead of causing an explosion of pink colored clouds, with an actual boom, she summoned a familiar that wouldn't even listen.

"Don't know, don't care. Just going to look to get back home." Saito said as he continued walking in a random direction.

"You're not going anywhere!" Louise called as she grabbed Saito by his coat when only ended up having Louise being dragged.

"Ok as funny as this is all good thing must come to an end," came a voice just before Saito was being lifted up by magic.

Saito looked down with a bored expression as he saw Louise smirking. Saito then took out Royal Flush and fired at the boy who had a fake rose shooting his wand out of his hand. Causing Saito to come back down. "Ok pretty boy never do that again," he said in a cool manner as he landed on his feet. He then looked up to the sky and saw two moons. "Ok why the hell are there TWO moons?" he asked confused.

"You really don't know where you are do you?" Louise asked as Saito sighed.

"Ok I see where this is going but if I'm going to be your familiar then I'm adding some stipulations," Saito said as Louise didn't know what these stipulations were but if it kept her familiar here then so be it.

"Fine what are they?" she asked as Saito grinned.

"I'm to be treated fairly and like any other human being, second I don't do laundry or anything that can easily be done by the person who owns said item unless it's a favor, second I'm more of the offensive type so I'll protect you in a fight, and finally we're PARTNERS not master and servant but friends allies Partners got it memorized," Saito said as he Louise nodded. "Good," he said before heading to the academy.

"Wait we need to get to know each other!" Louise called as Saito sighed.

"Fine what do you want to know about me partner?" he asked as Professor Cobalt seemed to have been forgotten.

Louise honestly had no real clue what she wanted to know as Saito just walked off, since he decided to at least get some bearings. He already figured since everyone had a common theme, that he was back in school. He had problems during school because of his lineage, but he had some knowledge from the schools themselves. It was something that he probably enjoyed in a small manor, at least the girls were hot, somewhat.

Louise went to catch up to Saito only to catch him heading to the dorm rooms. Louise led him to her dorm room and she was about to order him to do her laundry before remembering there little contract and sense she had to be a woman of her word she decided she would have a maid do it instead later.

"So Lady where am I supposed to sleep?" he asked as Louise glared at him.

"On the floor of course," she said before Saito walked over to her sofa and laid on it. "Hey that's mine!" she called as she saw him plop his feet on it and used it like a bed.

"Good night," Saito said as he went to sleep.

"That ass hole that's it when he wakes up he can forget about eating tomorrow!" Louise yelled as it didn't seem to wake Saito up as she noticed Saito's sword she saw that its hilt reminded her of a dragon as she could have sword it let out some purple lightning through the blade.

Louise then sighed before going to her own bed. "Good night," she said as she didn't care if Saito heard her or not.

(Scene Break)

The next morning, Louise woke up with the space next to her empty and unsure where he went. She then started to search the place, as it was considered a disgrace to have a familiar run away from her master. It was when she was at the courtyard that she saw Saito practicing with the sword that was on his back.

She noticed that the way he fought was that of a show off but at the same time very effective in combat. If she didn't know any better she would have sworn he was trying to impress someone. It was then that she noticed a plate of food nearby that she had never seen before. It was circular as it had many different toppings on it. It was soon that he stopped and went over to the plate and grabbed a triangular slice off and ate it. Now Louise knew she wasn't just dealing with a commoner but also a warrior and a sneak.

"He is SO dead," she said as she went to change into her school uniform and go after him.

(In the courtyard)

Saito was enjoying his Pizza when he saw Louise running at him. As he looked he sighed before lifting up his plate of Pizza he taught the chef to make this morning as Louise charged through where the Pizza once sat.

"Morning Louise want some?" he asked offering a slice.

Louise glared at Saito before she began to speak and she sounded pissed off. "Ok why weren't you in the room this morning?!" she demanded as Saito shrugged.

"Simple needed to do some training and I was hungry so I took the liberty upon myself to grab a bite to eat nothing special," Saito said as Louise glared at him.

"But you slept on my couch which I told you not to which I was going to punish you by not feeding you and here you are eating anyway, the training I don't mind but you could have waited for me to wake up!" she scolded as Saito was cleaning out his ear.

"Hey I have better things to do then wake you up and we did have an agreement that I wouldn't do laundry or any chores," Saito said as Louise huffed. "So want a slice?" Saito asked as he offered a slice of Pizza to Louise.

Louise looked at it before sighing in defeat and accepting the slice and taking a bite out of it and surprisingly it tasted good she had never tasted such a combination of ingredients. "What is this delicacy?" she asked as she dug into her slice.

"Pizza see the fun part about Pizza is that when making it you can customize what toppings you want on it," Saito said as Louise finished her slice. "Plus it's the food of the Gods," he said as it looked like Saito was a pizza maniac.

"Well I wouldn't say food of the Gods but I must say you know your way around a kitchen," Louise said as Saito chuckled.

"Well besides this I can only make Milkshakes, sundaes, and smoothies," Saito said as Louise nodded.

"Yes well you need to escort me to the dining hall for breakfast," Louise said as Saito shrugged.

"Ok," Saito said as he grabbed his Pizza and carried it with him as he at the slices.

(Later)

They arrived at the dining hall to which Saito noticed all the breakfast on the table as there was a plate in front of each student. Saito looked at the last available seat and put two and two together. "Well I brought you here so if you need me I'll be enjoying my Pizza," Saito said as he walked off leaving Louise standing.

"Wait Saito what about pulling my chair for me?" she demanded as Saito gave her a wave.

"Sorry only do that for girls I date not some girl I just met," Saito said as he walked off. Louise huffed as she swore Saito will be the death of her before she sat down and began to do the Morning Prayer.

(Scene break after breakfast)

As Louise and Saito were walking through the courtyard Louise noticed that Saito's sword was missing from his back. "Hey Saito where's your sword," Louise asked as Saito shrugged.

"Well when I don't need it, Alastor goes to some seal on my back and stays there until I need it in battle," Saito said as Louise was believed him to be lying.

"I don't believe you where is this sword Alastor for real?" she demanded as Saito shrugged.

"If you don't believe me that's your problem not mine," Saito said as he soon noticed that the Second years were outside and not in class.

"Hey Louise why is everyone here and not in class?" Saito asked as Louise figured a commoner wouldn't know.

"Today second years have the day off to bond with their familiars so these tables were set up for that," Louise said as Saito noticed a couple of second year babes. "So I'm going to find us a table you get us some tea," Louise said giving Saito the perfect time to do some flirting.

As Louise left to find a table for them to sit on Saito went to check things out and find the tea bags. But Saito soon bumped into someone making her drop the cake she was delivering. "Oh my apologies," the woman said as Saito noticed she was kind of hot and was well gifted in the bust area.

"Hey no sweat babe it happens," Saito said as the woman looked at Saito curiously not knowing what 'babe,' meant when it was used to describe an infant. Saito instantly recognizing his screw up quickly fixed the problem. "Sorry where I'm from some people call the opposite gender that as a world of endearment," Saito said as that made the maid blush. "You know what never mind how about I deliver that cake you were delivering," Saito said as the woman nodded.

"Of course but it's my job," the woman said as Saito smiled.

"Nonsense it's the least I could do to make up for bumping into you but if you want to help us be square mind telling me your name?" Saito asked as the maid nodded.

"My name is Siesta it's a pleasure to meet you Familiar of Louise," Siesta said as Saito forgot to tell her his name.

"Don't call me familiar sense my name is Saito but a lot of my demonic enemies call me Saito the Demon Slayer," Saito said as Siesta nodded as believing that there were demons out there that have been able to terrorize people without fear ever since the extinction of the Nephilim.

'Maybe he's also one,' Siesta thought with hope for an unnamed reason.

Siesta quickly banished that thought from her head as she knew the Nephilim were gone and were never coming back all because of what some people did out of fear.

"Well Siesta I have a cake to deliver," Saito said as Siesta stopped him.

"The cake is meant for that table over there," Siesta said pointing to the table that Saito recognized the sitter as that pretty boy who's want he shot out of his hand.

'Well what do you know he's with a different girl then the one from last night from when I was training man time to show this punk how to really treat a lady,' Saito thought before he started heading for the table and took notice to the perfume that fell out of his pocket setting up for Saito's greatest form of payback for lifting him up with his gay wand.

"Here sir your cake," Saito said as he placed the plate on the table.

"Thank you servant," the boy said as Saito wasn't done.

"But pardon me sir you seemed to have dropped this perfume the first year from last night gave you," Saito said as he picked up the perfume as the boy was shocked.

"That's not mine," the boy said as he looked at Saito and saw it wasn't a servant.

"Really considering it fell out of your pocket and it's the exact same one that was given to you when I was training last night," Saito said as Guiche was shocked.

(Flashback)

Saito was slashing with his sword when he heard laughter. Now being the curios boy he was went to investigate to see what was going on. He soon saw the boy who lifted him into the air and Saito ended up shooting his want out of his hand.

Saito then gained a cocky smirk seeing excellent black mail material before saving it to memory.

(Flashback end)

"Guiche what's going on?" the blond girl Montmorency asked as Guiche tried to weasel himself out.

"Nothing I don't know what he's talking about," Guiche said as Saito smirked.

"Really does the term I can't lie to your eyes ring a bell," Saito said as Montmorency seemed to be getting ticked off with Guiche. "Now all you need is a love letter to fall out of Guiche's pocket and then we have a full two hands in red," Saito said as if someone up there was on Saito's side hopefully his mom about 10 love letters fell out of Guiche's pocket. "Busted," Saito said with a grin as Montmorency picked one up and turned red in the face.

"You lying deceiving leach!" she yelled before slapping Guiche.

"My work here is done," Saito said as he was walking away now.

Guiche was pissed now that everyone was laughing at him making Guiche mad. "You commoner," Guiche called as Saito turned to him.

"Sup," Saito said with a wave as Guiche looked slightly taken back by Saito's act of indifference to him.

"You have ruined the reputation of a young maiden thus I cannot allow to go unpunished and have insulted a noble such as myself," Guiche said as Saito had a bored look.

"And I should care because?" he asked as Guiche wouldn't allow this commoner to shrug him off even if he carried a large Sword on his back without the help of straps and shot his want out of his hand which is why he had a bandage on it.

"Because I challenge you to a duel you piece of trash," Guiche said as being called trash reminded Saito of his encounters with Demons in his childhood as well as arrogant rich humans who he beat up and got sent to jail for.

"Fine I accept your challenge mainly because people like you really piss me off," Saito said as Guiche nodded knowing he's going to win.

"Very well we shall meet at Vestri Court in one hour for our Duel," Guiche said as Saito had another smart ass comment to say.

"Why one hour why not right here and right now it be much more interesting unless you need to psyche yourself out because you're scared to face me right now," Saito taunted causing Guiche to walk off to control his anger. Saito grinned as he just loved pissing people off. He then began to walk off to prepare for his battle which was eat be lazy and think on how to make an entrance.

But when he walked off he saw Louise stomping to him pissed off as Saito figured she had something to say. "What the hell are you thinking accepting a challenge against Guiche," Louise said as she tried to drag Saito only for him to be grounded without even struggling to not get dragged.

"Where are you trying to take me?" Saito asked as Louise was having trouble move Saito.

"To apologize to Guiche maybe if we can calm him down enough we can stop this fight," Louise said as Saito smirked.

"Sorry people like him really piss me off so I'm going to kick his ass," Saito said as Louise was against it.

"No Saito don't you realize he's a noble so he can use magic all you have is your odd gun and your sword," Louise said as Saito cupped his fingers under Louise cheek.

"Hey don't worry about it babe have faith in you familiar after all I'm Saito the Demon Slayer I kill demons who use demonic magic on a daily basis so a spoiled rich boy won't stand a chance against me," Saito said as he had a smirk on his face.

Louise didn't know why but the way Saito said it showed he has the power to back up the talk so Louise sighed in defeat.

"Fine but if things get to messy then I want you to surrender and apologize," Louise said as Saito nodded and headed to where he was going to have his duel.

(Scene break 1 hour Vestri court)

Saito and Guiche were staring each other down as Saito didn't seem too worried about the fight. "So pretty boy any last words before I kick your ass," Saito asked as he was going to love what was to come next.

"Well then let's begin our duel," Guiche said as he swiped his rose wand and allowed a rose to fly off and when it landed it turned into a Bronze Golem as Saito saw it looked female.

"My runic name is the bronze and sense I am a Noble with magic my Valkyrie shall be your opponent," Guiche said as Saito smirked.

"Bring it on," Saito said before the Valkyrie charged at Saito and punched him in the face but he wasn't sent flying in fact he was rooted to the ground as not even his face was moved.

"Is that all you got if that's so then it's my turn," Saito said before grabbing Alastor off his back and turning it into its Hell form Juggernaut and used the hammer half smashing the Valkyrie into a pancake.

"My Valkyrie," Guiche cried as he saw that Saito's sword turned into an odd but demonic looking weapon.

Nearby Kirche and Tabitha watched as Tabitha's eyes looked. "Demonic weapon," Tabitha said as Kirche also noticed this.

Guiche then sent out more pedals making more Valkyries rise as Saito smirked. "Hey Guiche its time I teach you a lesson on how to impress woman," Saito said as Juggernaut turned into Eclipse as nearby Tabitha was not visibly shocked if her eyes widening slightly was anything to go by.

"Angelic weapon Nephilim," Tabitha said as Kirche heard and was shocked.

"Wait but aren't they extinct?" Kirche asked as people overheard the two and began murmuring that Guiche is fighting a thought extinct race and he was Louise familiar.

Saito then began spinning Eclipse before swinging it sideways sending the Valkyries air born with a gust of wind. Saito then smirked before jumping up starting Saito's counterattack. "FIRST I WHIP IT OUT!" he called out as he was soon then began swinging Eclipse ready to attack. "THEN I THRUST IT IN!" he yelled as he began slashing the Valkyries. "WITH GREAT FORCE!" he yelled as Saito sailed through the air slashing up Valkyries. "EVERY ANGLE!" he called as he continued this air ballet. "IT PENETRATES!" he yelled as he was coming closer to the ground so he used a Valkyrie to propel himself to the air and place it where it belonged. "UNTIL WITH GREAT STRENGTH!" he continued as he held his weapon with such skill and prowess. "I RAM IT IN!" he yelled slicing a Valkyrie and sending its weapon dead into the center of a heart made of Valkyries.

Saito landed in front of the giant heart with a rose in his mouth as he had a smirk on his face. He then took out Royal Flush and aimed. "In the end…" he began as he then pulled the trigger hitting the spear in the center creating a broken heart effect. "We are all satisfied," he said before pulling the rose out of his mouth and looked at a crowed of girls swooning at Saito's little poem. "And set free," he said throwing the rose to the girls causing them to nearly get into a brawl over it.

"I… I yield," Guiche said as all his Valkyries were defeated and by a Nephilim who knew how to fight.

"Good next time think of your pickup lines and if you decide to two time try a little more tact and make sure the two girls don't know each other and never cross paths," Saito said as Guiche nodded wondering why he never thought of that.

"SAITO!" came Louise's voice as she stomped torts Saito as she looked excited and happy.

"Yeah Louise?" he asked with a relaxed look on his face.

"You have explaining to do," she said before dragging Saito off to her room so she can get a full explanation.

(TBC)
