This is my first fic in the Highschool DxD world.

IV: Enter Factions Three

Harry had left his message, with the help of Dumbledore who burnt the message into fabulously gaudy marble flooring of the Ministry of Magic and it detailed the changes that the magical civilisation needed.

Sirius and Remus by now had reached the foyer and one grabbed Harry and the other grabbed the staff and they left the Ministry and headed to the Goblins. The three of them left England three days later, there destination Kuoh, Japan.

(Time skip three weeks later)

Harry collapsed bonelessly on the couch and Sirius landed in the armchair. After moving to Japan and investing money into various properties and projects, they had quickly established themselves as a Godfather Godson duo who were good to the neighbours and generally decent people in the neighbourhood.

"Harry, I got a call from the Board of Governor's from Kuoh Academy. It's recently turned co-ed with a heavy imbalance of female to male students…You're a lucky man, all of those beautiful…"

"Yeah, yeah…I know. I'm no pervert, Sirius. I just want a nice quiet time for the end of my schooling.

Harry nodded "Okay, when do classes start?"

"You start next Monday."

Harry sighed; little did he know that his time as a Wizard had made him more aware of the supernatural. Little did he know what Kuoh would throw his way; in the form of a black haired and purple haired sadomasochistic Priestess of Thunder and Lightning.

(Monday)

To say Harry made splash was a hyperbole. All he could say was thank god that he was able to pick up languages and writing them rather quickly. He slotted into the school as 1st year, and had quickly caught the eye of several people. "Look at him, he's so handsome!", "Have you seen his eyes? They're like emeralds."

Harry paid no attention to the fangirling and decided to keep his head down. The first person he attracted the attention of was Tojou Shirone, or Toujou Koneko; a petit silver haired, yellow-eyed sweet obsessed girl. "Must tell Rias and Akeno-sama and ask for sweets. He smells strong."

"Odd…definitely odd. Might want to tell Sirius and Remus…Oh wait; they're out of town for a few days! House to myself!" Harry couldn't help but grin. Living with his honorary uncle and godfather was cool, but it did become slightly boring.

"You okay? You look lost." Someone asked. Harry spun; his nerves already heightened at being in a new school. Here he was, hopelessly lost. Someone had approached him! He hadn't detected him! "Harry, you're paranoid…you're much better than this. You've been off-centre the moment we moved." He looked, the person turned out to be a young man, his age, maybe older. The most captivating thing about him was the fact, he was distinctively of what people would refer to as Western Heritage.

"Yuuto Kiba and you are?"

"Potter Harry…And I'm kind of lost."

As the pair shook hands, the Knight Class Devil, felt a surge of raw unprecedent power wash over him "Rias-Sama needs to know."

"Odd…" Harry after meeting Koneko and Kiba, decided to keep his eyes open on anyone else. He had the distinctive sinking thought that, he had ditched the Magical World and was now about re-enter albeit from a different direction.

It was during lunch that Harry bumped into them. Like the Sacred Gear, he had been born, with unlike the arsenal of weaponry he had access to, he could feel the untapped power residing within the boy. Harry grinned, this could be fun…then using the Invisibility Helm or Cloak. The Cloak was a gift from Mannanan to one of his ancestors, it was helm originally when manifested but now it was something else; more akin to an extension of the mind. These days it was a cloak, no-one in the know was around nor could anyone see him, Harry walked forwards his form slowly melting out of sight, feet first.

Hyodou Issei, Matsudo and Motohama all lay on a hill, relaxing. As Harry walked over to them making sure to step where they were lying on their backs. Harry paused, the three were griping about not getting girlfriend of all things…Harry, shrugged. He closed his senses extended.

Anyone supernatural albeit a Wizard, Mage, Magician, Warlock, Devil, Fallen Angel and anything else unmentioned; had magical senses. These senses were more like extremely primitive radar combined with something akin to various insects and mammals all of which had some sort of senses. Most people didn't bother to hone them, Harry did…It didn't mean he could tell what he was sensing but he could feel something. It was emanating from Issei, but not fully…It was as if it was dormant and required a push.

In the Occult Research Club; a red haired western looking girl sighed as her opponent a raven-haired bespectacled girl put her in checkmate in their chess match. In the Research Club were two other girls, both of whom stood behind the two-playing chess, almost differentially these students were: Rias Gremory; Akeno Himejima; Sona Sitri and Tsubaki Shinra, these four particular gorgeous women with uniforms that left very, very little to the imagination happened to be Devils, both pure-blooded and reincarnated. The difference is neglible, except reincarnated devils served the pureblood devils…but things are a little more complex than that.

As Sona was about to brief Rias about where she went wrong in the match both Kings and Queens of their respective peerages stiffened. "Sona…"

"Granted Rias…I'm not sure who the originator is but I do know that they are exceptionally powerful." Sona replied not looking at her "Although, I do want to meet him."

(Church)

In the dilapidated and forgotten Church to the western most outskirts of Kuoh, four people rested somewhat comfortably on the pews. There three women and one male and the four of them could not be more different from one another, the first was an attractive young woman in short black dress and purple jacket, she would have looked gorgeous If not for the large raven-black wings emerging from her back and the glittering envy in her eyes. This was Raynare; a Fallen Angel.

The woman to her right wore a maroon trenchcoat style top and matching skirt with heels, the only thing off-putting about her was the aura of sadism that she constantly emitted, this was Kalawarner.

The final female directly opposite Rayner, could be best described as a Gothic Lolita, she was by far the smallest of the group, her name was Mittelt.

The final member of the group, was around six foot in height, impeccably dressed with a black fedora this was Dohnaseek. All four of them had black wings out stretched; they were all Fallen Angels. Cast out by God, for succumbing to human emotions when they were created to be above humans.

"Have you felt that? An awakened Sacred Gear!" Exclaimed Raynare.

"Aye, powerful, well-trained…Could be a threat." Dohnaseek rumbled. He had chosen to join Raynare, not out of orders but boredom. He had no desire to speak more than needed, nor did he exactly want to go antagonising the Sacred Gears, thank you very much. He remembered the Britannia Matter too well. The only other one who did was Raynare, but she was too young to have even participated in it.

"We observe, I'll think of something to keep the two gears from either awakening or destroying us." Raynare said, seeing the other three nod and vanish. Raynare grinned and shifted herself into a younger schoolgirl of an appropriate age. She had work to do.

(A few days later)

After inadvertently making contact with whatever it was in Issei, made Harry in the words of the hero Luke Cage 'Hide in the Cut', or rather "go to ground" minimise his presence magically.

Unfortunately, as he would later learn…He was good at stealth but concealing and mis-direction he was not. Everyone would have ignored him, but the rapid hiding had in fact drew more attention to him. Harry had then decided to up his training, with the assistance of his Sacred Gear, who if he were human would have been sniggering at Harry's antics was helping him rebuild his old skills and brush up on his sword skills.

Harry, quickly found that Fragarach was less a leaf-like blade but rather a weapon designed to take shape on his imagination and need. Some of the other artefacts he had in his armoury were also particularly nasty, not including Moralltach; the sword of agonising death from a single cut but there were others. Harry grinned as he concentrated "Dyrnwyn, fierce and bold…Dyrnwyn, the sword of the righteous, Dyrnwyn hear my plea and judge me worthy dark times are coming…Dyrnwyn, I summon thee."

There was a flash of light, accompanied by roaring heat as a barbed bastard sword erupted into existence. Any idiot could wield the sword of the righteous, but it'd just be a bastard sword with bite…but in Harry's hands the blade erupted with blue flames soaring off it. "It appears Dyrnwyn has deemed you to be a worthy wielder, partner."

"But why?"

Harry felt the Dragon shrug "I would say because you're a dragon-champion…But it's more likely due to your upbringing; as much as I curse our relatives, you'll never do anything that would deem you unworthy…I'd suggest we go for a run."

Harry nodded, his hand went to the piece of paper, or flyer that he had received earlier. The magic on it was unmistakable, Remus who had been home this particular day, quickly informed him that it was a contract flyer and it was related to the Ars Goetia and the Treatises of Solomon, both of which the Potter's had copies of.

Harry smirked, if everything he had learnt since he was thirteen was true or even vaguely true, he for once would be more than willing to kick the hornet's nest. "Uncle Moony, going out for a run."

"Enjoy. Be careful."

Harry had no idea that his thoughts of booting the hornet nest would happen like this. The run would take him in circuitous route in the form of a figure of eight, crossing through the park four times. The only reason it was this long was due to his were-form granted him endurance and stamina on top his strength and other physiological improvements. For a humanoid, he was packing a lot of power.

The run began uneventfully as he began to jog down the streets, he moved fluidly around late-night walkers, vaulting over cars, fences, through fences and off walls. It may have been described as hooligan behaviour, but the moon was out and it made him feel alive. When he hit the woodland trail section, he took three steps and effortlessly shifted into his as Remus informed him "Werewolf-on-steroids" form. It looked like something out of Adventure Quest, a game that Sirius seemed to be addicted too.

Harry much preferred his Roleplay Games, Anime and Manga. He would never be a fully functioning adult, but he would be more functioning than Sirius. Remus, apparently was the only one who was more functioning than the pair of them aside from his own moonlit runs. He shifted seamlessly into his human form as he burst out of the woodland trail in a roll onto his feet.

As he rounded into the park, he felt the world shift subtly.

"Issei…would you die for me?"

(Issei)

Issei, had a well time the of his life. A girl had literally just asked him out and after school, the pair had a fun time. Rather, Issei had, the girl seemed to be waiting on something. Now, here they were in the park as night was falling.

"Issei-kun, would you do anything for me?"

"Anything."

"Issei…would you die for me?"

(Normal)

Harry, was fast. Everyone knew that…well those did know, but the three hundred meters between him; Issei and the well Fallen Angel, the light spear appeared and as Harry crossed the ground, the spear descended, followed by another.

Unfortunately, multiple things happened. The blood seeped into Izuku's pants pocket and activated the flyer in his pocket. A sigil appeared, Harry stepped up his speed "Dyrnwyn…I summon thee."

Rias quickly surveyed the scene, she had appeared in the sights of a Fallen Angel! "Fallen! I strongly advise you to leave the territory of Kuoh; you are unwelcome in the territory of House Gremory, in the name of Rias, Heiress of House Gremory."

The Fallen Angel giggled maniacally "I'll get a…"

"Loss of body parts crow." Both Devil and Fallen looked as they saw Harry rush over, he slid to a stop. The only difference was, the fact he was carrying a sword and it was on fire.

"What's a boy with a burning sword going to do…how about DIE!" Shrieked Raynare as she launched the light spear. Rias, was torn assist Harry or Issei…it turned out Harry made her decision for her.

Harry snorted as the light spear headed towards him, he was already bringing his sword up and he effortlessly blocked the light spear. Harry smirked, "What you don't like my sword? Well you'll love this. Bloom Dyrnwyn, Bloom in and deliver blinding justice!"

The blade suddenly erupted with blue flames and Harry closed the distance, pirouetted and brought the sword upwards the intent to cut the Fallen in half.

Raynare, predictably shot upwards only to see a glyph appear as red, eldritch light rocketed out of it. Raynare darted for the ground as Harry, tucked and flipped like a cat-out-of-water, intent on getting out of the way of the light. His eyes widened "You're the Duchess of the Destruction! The supernatural grapevine warned me you'd be here, never thought I'd be at school with her." Harry called as he swung the sword at his opponent.

Raynare spun "I tire of this mortal. Begone!"

"As have I, Crow. Dyrnwyn, swap, Frag…" The blazing sword vanished and another appeared. This made Raynare pale.

"NO! NO! WE WERE TOLD YOU WERE DEAD! ALL OF YOU!" She screamed, gone was any sort of strategy, a red cloud descended in front of her as she spread her wings wide and she hurled herself forwards, more light-spears appearing around her.

"Pierce through! Overcome! Fragarach!" Harry intoned, the sword turned into a whip and like a striking snake, deflected the swarm of light spears then it changed into a lance and the shot punctured Raynare through the chest connecting solidly and through her heart. Raynare's body went limp and slid down the lance.

"Wonderful, I just turned a gorgeous crow, a sadistic one, but still beauty is beauty, into a fucking kabab." Harry growled as the lance changed back into a sword, a sickening squelch was heard and before Raynare's body could hit the floor, another sword materialised and parted the head from the shoulders.

"That bitch'll have a hard time getting on the Ferry…Now Heiress Gremory, I shall see you tomorrow."

Rias snapped her fingers and Issei woke, as her peerage teleported in "I think not, Harry-san. We need to talk right here and now."

"I would but you have a new piece to look out for." That triggered it; Rias, Koneko, Akeno and Kiba started to look out for Issei, Harry activated his invisibility spell and vanished from sight.

(Rias)

"Koneko, Akeno take Issei to his house. Kiba, you and I will clean up this mess…I might have to send a report to Maou-Serafall and Maou-Lucifer. We have a dead Fallen, now Harry…" Kiba had to fight back a smirk, it seemed Harry was definitely going to be a pain.

"Something funny Kiba?"

"No Buchou…Just thinking that the future will be entertaining."

(Harry House)

"How was your…You, okay kid?" Asked Sirius.

"We live in Devil Territory, I was attacked by a Fallen Angel and I may have kickstarted a war…So, a little out-of-my-depth right now." Harry responded as his body shook as the events of the park were remembered.

(Grigori Command)

"Governor-General, it's Raynare…She's dead sir."

The Governor General, looked at the runner and his advisors "What happened? Who did it? Why did they do it?"

"I'll find out Governor."

"Vali, go find out what happened…I need to make some calls." The Governor General strode over to a desk, with a heavy sigh sat behind it and picked up the phone.

"Can you patch me through to Maou Leviathan and or Lucifer."

(Underworld)

"Maou Lucifer…Governor General, this is unexpected. My condolences on the loss of the operative…Yes, yes of course, I shall investigate. This is brand new information given to me by both Sitri-san, Maou-Leviathan and Rias-tan." With that Lucifer hung the phone up.

"Grayfia-chan, I'm heading out. Maou business."

"This wouldn't be an attempt to shirk the meeting with the Marquis Phenex would it?"

Lucifer pouted "That was the Governor-General on the phone…"

"I shall make the excuses."
