The Grand Order of Holy Knight

Disclaimer: I do not own anything on this story except the idea.

AN1: So I decide to change my crossover fic from Rurouni Kenshin to Naruto although the involvement also changed into Nasu-verse general and please be known that this fic is involving Fem!Naruto.

Warning: This will be a bit of an OP Fem!Naruto and she will be a bit too wise for her own age, but after reading this fic you will know why… Oh and future warnings for character deaths… there will be lots of them so if you are not into that I suggest you drop this right now.

Pairings: Undecided for now but I will welcome any pairings except Sasuke and Fem!Naruto.

Chapter1

The moon was shining ever so dimly as a battle -no more of a slaughter- raged on beneath the cloudless night sky.

In the middle of a graveyard, several corpses were laying a strewn, sliced, smashed, battered, frozen, and destroyed. They were all that remained of the loyal vassals of a proud vampire who carried the name of Tepes.

Ashen silver hair was waving about fiercely despite the lack of wind as the proud vampire noble found himself fighting for his life against one of his kinds most natural enemies. No it wasn't the likes of the lycan of olds that the creature found himself against but rather the simplest of all his foes.

Humans.

Fragile by nature his enemy was supposed to cower down upon his wake begging for mercy to which he was supposed to respond by killing his opponent with merciless brutality and utmost condescension.

But that was not the case.

For his enemy was far beyond what he expected.

Clad in armor his two adversary appeared out of nowhere and forcefully stopped him from enjoying his nightly ventures of hunting down virgins to rape them to no ends and suck out their bloods until they were nothing more but dry husks.

In less than a minute after their appearance, his court of minor vampires and ghouls numbering hundreds were cut down to just him remaining, and by the way the battle was going on he was sure that he too would follow the footsteps of his allies.

Him a proud vampire of the great lineage of Tepes losing against two mere mortals.

Just the thought ignited the fiery inferno of rage and hate that he felt within him to no ends.

Claws sharpening, canines lengthening, demonic wings flapping about along with black malicious aura cloaking his entire frame the vampire roared out in endless rage as he charged at one of the two beings that dared to humiliate him, an adolescent female holy knight with blond hair and violet eyes, cold unnatural violet eyes.

Like a matador to a bull the vampire's target easily moved away from his raging charge. With footsteps barely audible and movements almost impossible to catch even by the sharpest of mortal eyes, a sword appeared in her hand cloaked in holy crimson flames.

The vampire's wings waved about elevating him higher and higher into the night sky until he was far from the exorcist's reach. "You detestable human! Know your place!" the proud vampire shouted as he suddenly dive bombed through the air, shooting himself towards the holy knight.

"I know my place." The blond holy knight whispered as her eyes followed upon the vampire's trajectory carefully looking for a perfect timing to counterattack.

BOOM

A sonic boom passed by nearly blowing the holy knight away as she barely evaded being plowed through by the speeding vampire.

BOOM

Another wave of wind shot against the holy knight's body as the young woman was barely able to evade a swipe from the vampire. Three small claw like gashes appeared on the young woman's vestments drawing out blood while the noble from the immortal house of Tepes continued his maddening assault.

SLASH

With his superior capabilities the vampire landed another swipe with his prolonged claws wounding the evading holy knight's shoulder.

SMASH

The vampire's fierce wings crashed against the holy knight's stomach forcing the female to lurch forward.

SMASH

A punch to the jaw launched the blond holy knight high up in the air enabling the Tepes to land a flurry of strikes that the holy knight barely managed to avoid and block with her halberd.

CRASH

With a high-arching axe kick the vampire sent the blond holy knight crashing towards the ground creating a small crater beneath the wake of the blow.

"Hahahaha! Having trouble keeping up human?" boasted the airborne vampire as he was surrounded by a larger amount of dark miasma.

"…" the injured holy knight didn't bother to respond as she slowly stood up from the crater.

Her entire frame was marred with cuts and gashes that continued to bleed, along with the bruises that darkened with each passing second. Yet, for some reason the blond holy knight looked barely phased by the assault. Yes, despite her grievous injuries that without a doubt have killed a normal human the young woman acted rather indifferently, it was as if the holy knight didn't care about all the damage her body received.

In essence, that wasn't far from the truth.

The vampire clicked his tongue in frustration as his opponent showed no signs of fear or even panic despite being injured. "I bore of you and your existence… I guarantee that with this next blow you shall die. That is your future you whelp." The creature of the night stated before he came flying down towards the holy knight spinning downwards, creating the impression of dark crushing drill that will mow down all that was unfortunate enough to be caught by the attack.

The blond holy knight closed her violet eyes.

After her training with the Sage of the Six Paths, the blond realized that she has an eyes which were always noted to be superior then that of a normal human.

Her eyes allowed her to pick up and track fast-moving objects along with enabling her to pick up on even the most subtle of details. With her eyes she could even see the flow of the life energy of the world allowing her a greater advantage in tracking down her enemies along with avoiding life threatening attacks from enemies whose speed far surpasses her own.

Many hailed the blond for her eyes that she apparently inherited from her ancestor but she cared little about it. To her this eyes were just a tool, one needed for her endeavor of protecting the life of the others.

It was because of her powerful violet eyes that the blond holy knight was able to observe the vampire's, speed, power, attack patterns, endurance, from the slightest to the most exaggerated of movements her eyes has seen it all. "I can see a different future…" the female whispered as she summons few black swords pure of energy around her.

Without even needing to look the blond holy knight knew that she had exactly five seconds before the vampire would reach and mostly likely kill her with the incoming attack.

She could see it within the eye of her mind, percentage wise she only had about a 5% chance of winning and defeating her adversary who was clearly superior than she was but the blond holy knight knew that as long that one percent exist then she could still pull of a victory.

With her eyes still closed the female started counting down to the inevitable.

Five

She calmed her nerves, her breathing was shallow and steady in preparation for her next course of action.

Four

Her senses extended, taking into account not only the sound of her approaching demise but also the stillness of the earth and the blowing of the wind.

Three

Her grip on her blade tightened, her mind worked into overdrive as she replayed her plan again and again looking for possible flaws and fixing them if possible.

Two

The holy knight's knee's bent down as she channeled most of the energy in her body called Chakra towards her limbs. The ground slowly cracked underneath her feet as she readied herself for the jump of her life. Her plan was fool-proof, all the variables has been taken into consideration.

"Your future is…" she whispered as the countdown continued dwindling inversely with the now fierce and deafening sound of the vampire's incoming attack.

One

Power exploded from her legs propelling the exorcist up towards the sky as high as she could.

"Death…" She whispered as she thought about the future that awaited both she and the vampire. If she were to fail then she was going to die, if the was to succeed then her opponent shall perish.

It was now or never, every movement from here on out must be precise and within the range of her calculations to make a mistake was to die a horrendous death.

There was no room for errors.

She had one shot.

Zero.

As if pulling the trigger of a proverbial gun the female's eyes shot open revealing her cold violet eyes unto the world. The blond could feel the wind clashing against her body proving just how high she jumped, snapping her head down she saw that a few dozen feet beneath her was none other than the spiraling mass off darkness which was the silver-haired vampire.

The man from the house of Tepes was currently grinding the ground where the holy knight stood mere moment's ago.

Just where the holy knight wanted the heathen to be.

In a span of a few seconds around the holy knights appeared many weapons created from her holy flames ranged from spear, sword, axe, halberd, and many more as she hurled all of them completely raining down on the vampire.

But it did not end there, for the very next words that came out from the holy knight's mouth proved to further push the vampire towards defeat. "O Lord, I entrust this body to you…"

With the uttering of a simple phrase the pillar of holy flames came out from sky and…

BOOM

The pillar of holy flames burn the vampire into crisp and everything around the holy flames bringing forth a maelstrom of fire and destruction.

Silence permeated the area after the holy flame vanished ended as not long after the end of the attack the dust cleared revealing unto the descending holy knight the several wounded form of the vampire.

Gone was most of his body leaving him only with his right hand, quarter of his body and half of his head.

Blood was everywhere.

That attack would have most certainly killed any lesser demons, but she was not the same. She was a proud vampire of the house of Tepes, a house whose weakest members were considered on par with noble vampire from other clans.

He could not fall here, at least not fall without dignity.

With an unearthly roar that shook the entire graveyard the wounded vampire lunged toward the blond but her body was impaled with spears as he cried in pain.

The blond looked at the noble vampire as she raised her hand, "Good bye."

"Che…"

There was no deathly scream of pain as the victor has been decided.

The seriousness of the situation was soon broken upon the sight of a smiling blond-haired kid with green eyes in armor cheerfully sat atop a tombstone several meters away from the now ruined graveyard that was filled with blazing holy swords, a torrent of blood, and a lot of corpses. "It's not like Naru to take this long…" the blond complained as his face didn't show any sign of worry although his partner was currently fighting one of the strongest vampire above the vampire king, Izraf.

Then from the graveyard came the blond haired girl as the kid hopped from the tombstones and walked toward the girl, "Nice job there, Naru." he said in carefree manner as he offered a fist which the girl fist pumped the blond boy.

"Thanks Meliodas and it seems that you already take care all vampires around here." the blond girl named Naru responded while looking at the destroyed vampires around them. "How about that, we evoked the wrath of a whole vampire family upon the two us…"

"I don't really mind. But it will be a hassle to kill all of those things."

"Really Meliodas? I was under the impressions that you can destroy all of them in blink of eyes with your demonic power for just fun time." exclaimed Naru as she started walking towards her partner who voluntarily sat out the fight so that she can battle the strongest vampire one on one.

The Diamond rank Holy Knight and the second in command of her, Meliodas smiled at his best friend's words. "And here I thought that you can just burn all of them with your holy flames without a care in the world." He quipped referring to his fellow blonde's habit of solving most of her problems by burning everything in her way.

"Against a horde of hundreds like that? I know my limits. Although if I was born with a Demonic power like you the Strongest Holy Knight then it might be different." Naru chuckled as she leaned on a nearby tombstone.

"Oh? Why would you say that? I was under the impression that you could born down hundreds with a wave of your [Demiurge], the flames of creation."

Naru smirked "Touché." she paused for a moment as a cool breeze clashed against her frame. What a chilly night it was. "So when is the cleanup crew arriving?" she asked her best friend.

"Since I already called them while you were having the fight of your life then I say they'll be here by dawn."

"Good" the Great Holy Knight nodded. "I really don't want to deal with the populace panicking upon the sight of burning swords and large hole in their graveyard."

"Don't forget about the corpses."

"True, true"

Both of them chuckled as their ears picked up on something. It was the sound of flapping wings caught not only his but also Meliodas' attention, effectively stopping their conversation.

Turning both of their heads to the direction of the noise the two holy knights found what looked like a pigeon flying through the night sky. "A carrier pigeon?" mumbled Meliodas, his eyes lingering on a small piece of spell-paper attached on the bird's legs.

Naru extended her left hand towards the bird prompting it to land on her extended limb. "Does that woman know if we already done or what." the girl muttered as her blue eyes gazing intently upon the message held within the simple piece of parchment.

"Is it another order?" Meliodas asked which the other blond nodded.

"Yes, it's a mission. A last mission for the Great Holy Knight Naru." The blonde responded as she burned the letter with her ability.

"So where are you going Naru?"

"Orders to go back to Liones first for debriefing… but the message says to prepare myself for a long term mission under the order of Bartra."

Meliodas whistled in an impressed manner, "Barta? Then it must be involving one of his vision."

"Yeah," the blonde girl nodded in response. "Whatever it is, it must be something that must be dealt with swiftly." she said in serious tone as both of them looked at the moon.

The sound of bells ringing out in a harmonic manner proclaiming the coming of the noon could be heard every so often from within the castle of the Kingdom of Liones.

Within the halls of this lone and majestic castle two holy knights stood in front of a wooden door. Just two old men clad in armor and wielding blades of life.

They were but a few of many who have lived their lives protecting and guarding this throne. In simpler terms the two were nothing but guards for the door which lead to the room where the King often resided.

"Have you heard?" one of the two holy knights, a man with greying features asked trying to break the ice in order to alleviate himself from the hellish punishment known as boredom.

"Hmm?" the other holy knight, one with white hair symbolizing that he was older of the two mumbled rather lazily.

"You know the Great Holy Knight Naru, right?"

The second guard priest nodded. "Yeah, who doesn't know about her?"

"They said that she is going to retire." said the younger one in whisper.

The older knight eyes widened, "What? The Great Holy Knight will retire!? Why? And isn't she the strongest holy knights in Brittania!?"

"The rumor said that she want to search for her family, what a poor girl…" explained the graying knight.

The older knight's eyes widened in surprise. "She is an orphan? I thought she is from a famous knight family like Sir Zaratras and Dreyfus." he said in surprise as he always thought that the Great Holy Knight was born from a high-class family when he saw her noble attitude and humble personality.

"Yes, she is an orphan. I also thought that she is from a renowned family, but who will guess that the Great Holy Knight Naru who is called as the Sword Saint is an orphan." he said in sad tone.

"Yeah who knows," the older one said as he looked at the ceiling. "Let's just hope she doesn't quit from the holy knights after finding her family, but who will take her place?"

"It's sir Zaratras."

"Sir Zaratras, huh? Well he is second only to Lady Naru, right? I think it's a good replacement. But where is her clan is?" the older man asked as the younger one furrowed his eyebrows.

"She come from a clan in East and far from Brittania. They said the girl was exiled."

"Exiled?"

"Well the rumor said that she holds a monster in her belly, but seriously who will believe that? I mean a monster in her belly? The merchant must be crazy." the younger man said.

"But it's plausible considering her inhuman magic power and skill… Maybe she isn't, you know, human?"

"That can't be a person as kind as her is monster. That's something that can't be true." the younger said as the older man nodded.

"That's true, there is no way a girl like her is monster." he said as he laughed at himself. "So tell me have you seen what the Great Holy Knight looks like? I've only heard about her features from rumors and have never really met her in person."

"They say she is a buxom woman, pale skin, has long blond hair, violet eyes, carrying a flag and sword as her sacred weapons and finally they said she was wearing a purple themed clothes."

"That is a rather detailed description."

The younger knight chuckled "Well... I'm actually part of her fan club… I can't help but to admire someone as strong as her."

"That's true, true." the older knight cheered out as the two of the descended into a fit of laughter.

As the two laughed they failed to realize a sixteen year old, blond-haired young woman carrying a flag in her hand walking towards them. She was clad in armor over purple themed clothes.

The blond eventually stopped a few steps in between the two guards who were still gossiping and ignoring her existence. "Excuse me," she said in low tone, stopping the two as they immediately looked at the girl for a moment, before they freaked out.

"Great Holy Knight Naru, we don't know you are coming!" the older one said as both of them saluted and the blond holy knight sighed.

"I'm here to meet Bar-I mean the King." the blond said in formal and professional tone. "Can you please let me in?" she asked, glaring at the two which made the two yelped a little.

"S-Sure you can go on, Sir!" the younger one said as the blond knight resumed walking towards the doors as she pushed open the wooden door and soon disappeared on the other side leaving the two guards to their gossiping.

The blond knight walked toward throne as she kneeled and her head bowed, "Welcome home, Naru. I assume the job is not as hard as it look, right?" he said as he gestured the knight to stand up and she did as he said and smiled at the King.

"Yes, Bartra-dono. The job is not hard as it looks." she said with a thin smile which make the King smiled at her as her eyes turned into serious. "Your majesty, I am sure that you are calling me not to talk such a simple thing, right? So can you please tell me my last job as holy knight?"

The King looked at the blond girl for a moment as he opened his mouth, "It's about the omen that I saw when I meet you." he said as Naru narrowed her eyes a little. "First of all I must said thank you as because of your work all chaos and ill omen has been dissipated… But the omen of the great holy war has not been dissipated, but has strengthened even further."

The blond knight looked at the King with serious eyes, "Bartra, what do you see?"

The King stayed silent for a moment as he answered, "I see Liones fall and clenched by the hands of two Holy Knights which I assume you already know who they are." he looked at the blond knight that could guess who they are and ready to kill them if he ordered. "But it's not you the one who saves it, it's a group of criminals."

The blond knight's eyes widened in surprise, "Group of criminals?" she asked as the king nodded.

"7 Great Criminals that bear each sins in their name will save this kingdom under Meliodas' leadership and you the Great Holy Knight will collect all of them." The King said as the blond smiled.

"So 7 Great Criminals, huh? I assume one of them must be the Undead Ban and the Fairy king." she muttered with interest tone.

"So how is it? Would you do it?" asked the king as the blond knight knelt on one knee, his head facing towards the floor.

"I will do it as my last job as the Great Holy Knight. I will collect the Seven Deadly sins and lead them to save this kingdom!" she replied with sure in her eyes, making this the day where the Seven deadly sins born.

A/N: There it is. Tell me what you think. I'm particularly hoping for constructive reviews on the pros and cons. I'm mainly writing fan fiction to improve my writing skills, so I appreciate anyone willing to take a few minutes to critique my work.

Please make it constructive though. I don't particular care if you hate my work, but please explain why with more than a 'This story is the worst in the history of fan fiction. F you.' Please and thank you.

So I decide to change the element of Fem!Naru from wind to fire for some reasons which will be explained later and her flame power is derived from Mathilde-Saint Omer from Shakugan no Shana and Joan'd Arc from Fate/Apocrypha, making her the strongest character baring Rikudo, Kaguya and Juubi.

But because Naru is a girl, she is more of a technique and speed type of character rather than a power type making her more of a glass cannon. (She can take hits but in the end her body is just that of a normal human.)

By Nanatsu no Taizai style power calculations, her power level will be:

Magic: 100 (her lack of magic is because of her Shinobi style training and more into brawl with sword making her having lack of magic)

Strength: 500 (her strength is sufficient power of girl who did a moderate training as holy knight no more and no less)

Spirit: 30,000 (her spirit is high due to her being Uzumaki Clan and a Jinchuriki which lead her spirit to be stronger than any beings)

Power: 40,000 (her power is astounding easily more than a match for Meliodas and generally on par with Escanor, but is this her real power?)

Her magic [Demiurge] is flame of creation utilizing the mix of yin-yang element and magic, making it far stronger than any magic and jutsu in general. The ability is mainly to burn and make an object but Naru is utilizing it for something more.
