This is my first fic in the Highschool DxD world.

XIII: Battle Ground

Harry and Akeno, were joined by Rias in front of the Sanskrit covered door "Behind this door is my Bishop; when I brought him into my Peerage; I couldn't fully control his power."

"Seems you do that quite a bit, Rias. Biting off more than you can chew." Harry replied.

Rias's eyes flashed and she rounded on Harry, her hair beginning to rise. "Why are you here? None of your sardonic, sarcastic and shite half-answers."

Harry gazed back not batting an eye at her attempt to remind him of his place. "I've quickly found that I'm less of a Pact Magician for you Lady Rias; I'm more of your problem solver. That's why I'm here, I'm here to help deal with Dhampir Dio Brando because you screwed the pooch."

Akeno stepped between the two "Harry, behave. Rias…Harry, for all his alphabetical and chronological problems, is only trying to help. Yes, he finds hilarity in being asked to do things by an incredibly naïve and powerful woman; so, he does them in the most destructive way possible."

"That and because it's funny to watch Rias get so exasperated by my comings and goings. Rias, you're helping me shift a lot of problems…There, I've said it. I'm helping you and you're helping because Yahweh preserve my testacies; we've both been shat on something awful. You, by your parents with that marriage pact to that utter Bell-End and me to the Wanded Sect of the Wizarding World. Now, I've Dhampir Dio to assist."

With that Rias, unsealed the door and Harry walked in "Dio Brando, up and at 'em."

The shriek and the sudden slamming of a coffin, made Harry smile. "Okay, Dio Brando; time for you to come out of the Coffin."

"But I like my coffin! My coffin is nice and safe."

Harry sighed "Fine, fine. I guess I'm going to have to eat all of these sweets that…I had to make additional deals to get for you. And, I've got some shows you might not have watched yet."

Gasper, opened the coffin slightly "You're not here to get me out of my coffin?"

"Well…not entirely. But I've been told by a certain Red, that you're a pretty decent magician with a boatload of power; before you became Red's bishop."

Gasper flushed slightly "I don't like conflict, I'm a scaredy cat."

"Neither do I about conflict; but Gasper…I'm not the best at this one-to-one inspirational stuff but you're in danger. I have a very good theory that this place is going to be attacked and you're going to be kidnapped."

"You would have been better saying 'Come with me if you want to live'."

"Don't you get smart-assed with me, Mr. Brando. I'm the one who's licenced to troll!"

Akeno and Rias both began to giggle at Harry and Gasper bonding "Gasper, you want to become the Prince of Trolls?"

"No, I want to become the God."

Harry raised an eyebrow "Why be a God, when you can be the God King of Trolls…I stop at sacrificing thousands of people a day to remain alive…But if you want that, you must leave what is safe and certain. Gasper, can you do this?"

Gasper shook his head "I can't. But I must." Harry's grin in Gasper's eyes reminded the teen too much of Alucard.

"My thanks for the reference. Believe me when I say, I rock that look."

"You also mentioned you'd rock the Seras Victoria look." Akeno retorted "And we haven't had proof."

"Akeno, once we've dealt with this, had dinner then I'll do the Seras Victoria."

Eventually the day of the peace talks arrived and the moment the Three Factions went to sign the treaty. Then true to Harry's words, there was the sound of reality itself tearing, accompanied by the sound of falling glass as Fallen Angels and Devils stormed the meeting.

At the meeting were for the Devils: Sirzechs Lucifer and his peerage, minus Grayfia; Serafall Leviathan and the Peerages of Rias and Sona respectively. Representing the Heavenly Host was Michael and elements of said Heavenly Host and finally, those representing the Fallen: Azazel; the Governor General and his two aides Shemhazai and Baraquiel.

Shemhazai and Baraquiel could not have been more dissimilar. Baraquiel was muscular, broad and gruff where Shemhazai was slim, slender and softly spoken.

Everyone at the meeting, including the Wizards who were acting as additional security stopped and looked up, as Devils and Fallen Angels entered the ghost dimension.

"Azazel, Baraquiel and Shemhazai, how low you have fallen, even for one of us. To sit at a table with our foes." Kokabiel mocked.

"So, you're Kokabiel…Have got to say; I'd thought you'd be taller." Harry retorted, attracting the Fallen Angels attention and full fury.

"You, insolent, pathetic human; one who should bow before his betters and superiors."

"As I've said before, insolent…most certainly. Pathetic? The misses would have to disagree with that. Human…you got me. Now as for bowing to my betters and superiors? Considering you're classing yourself in that category I spit in your general direction. In fact, people I consider my superiors and betters…none. Yeah, yeah, yeah Devils and Angels are naturally stronger than Humans but then again, you're designed to be. Humanity…we've got the ability to incorporate outside influences into our DNA. We can change; you lot…not so much."

Kokabiel hissed in rage and his red eyes glittered with unprecedented madness "You will learn much suffering."

"Was Tom Riddle, aka Voldemort, your son, Kokabiel? Because you certainly sound like him, slightly resemble him…a quick nose job and a 0 electric razor would do just fine." Harry retorted glibly.

Meanwhile at the Table the Three Main Powers hadn't done a thing aside from standing away from the table and revealing their wings. However, Azazel and his Ward, Vali Lucifer, were seriously fighting the urge to laugh. Sirzechs and Serafall mouths were upturned into grins.

Rias and her peerage and the Wizards were either face-palming or chuckling. "Was Harry like this before?"

"This flippant and whimsical? No…Mouthing off too much more powerful adversaries…yes." Hermione deadpanned.

However, the devil in the low-cut purple, blue dress snapped her fingers decided to make herself known "Enough of this meaningless banter. I am…"

It was Neville who spoke "Ah yes, voluptuous figure, almost certainly single and a bit of a black widow and now dresses like a hooker with intent in order to make an entrance. You've got to be part of the Original Leviathan family. I'm sorry ma'am but the Sherif is busy at this point in time, so you've to make do with the Deputy."

The Leviathan Devil almost screamed with rage, before gesturing with her staff and a sigil erupted in front of the Wizards. Hermione, Padma and Pavarti had their wands in hands and managed to with some difficulty reflect the pulse of magic sent by the devil.

At the same time Kokabiel unleashed a light spear and launched it at Harry, who had managed to just conjure a string of rapidly descending Earth Walls to stop, or at least slow the light spear. Harry shifted allowing the spear to fly past him. "Oh wow, care to try harder? I almost felt that." Harry mocked, he quickly dived through a portal that had occurred as Serafall unleashed her wings and went to confront the descendent of her title.

The portal spat Harry in clear view of Kokabiel; who had turned his attention to Rias, who had at that point unleashed a blast of Destruction at him. Kokabiel snorted, with the flick of an elegant finger a wall of holy light dispersed the energy sharply. "A worthy shot, daughter of Bael and Gremory. But try this!" With that a swirl of Raven Black feathers shot towards the peerage only for Azazel and Baraquiel to flare an impressive collection of Twenty-Two pairs of wings between them.

"Koka-baka, you really should have watched your back." Azazel mocked. Kokabiel turned, pulsed his magic and shattered the subtle illusion Harry had shattered. This caused further fractures across the limits of the ghost zone. His eyes widened and fighting lessened as even Sirzechs watched in amazement as Harry with the emerald green magic circle in his right hand and the blood red seal of House Gremory along with golden seal of Bael as well. They watched as the blood red and black energy converged into an orb.

"Potter Hidenmahou: Power replication: Power of Destruction." Harry gasped, sweat pouring down his face and his arms as his fingers began to blacken and crack from the potent properties of the power of destruction. "Kokabiel…here's…a taste…of OBLIVION! DESTRUCTION RAY!" Harry roared thrusting his hands forwards, breaking the seals and twisting his arms as he did so.

In that moment Harry forgot one thing. In the terms of magic, one of the most important things to remember was that belief, willpower, imagination and studying had a profound effect on magic. The twisting of the arms; made Harry subconsciously think of Dragon Ball Z; anime composed of screaming, constipated looks, big powerful energy blasts and twisting hands to make the technique more effective.

The energy blast fractured the dome even more, Kokabiel flared his wings and summoned a shield, only for the blast to rip through the shield like it was nothing. Unfortunately; Kokabiel wasn't a Cadre for nothing and managed to direct the blast into the school.

"Harry, don't you dare say it!" Neville, thundered as he hastily ripped up the tarmac and concrete in the artificial dimension of Kuoh High School; which happened to be on fire, to prevent the humans from being hit by high flying parts of the school.

"The building being on fire and it not being my fault?" Harry replied glibly as he narrowly avoided a diving Fallen Warrior. Said warrior was absentmindedly turned into a ferret by Remus.

"Remind us, Harry…Why you needed to summon the Purple Flying Chimpanzee to throw incendiary shit at people." Rias questioned as her own magical shield buckled under a light elemental spear.

"I've not spawned them yet…Besides; no-one's really got hurt." Harry replied as he saw his fingers slowly, heal.

"The realm is kinda trashed Harry…If it takes much more it'll appear to the public."

"We-all then, I guess we're going to have to step this up a bit." Harry mocked.

"ACCELERANT BREAK!" The armour reappeared around Harry. Harry threw down two magical spells and vanished. In his place was Serafall, and where Serafall had been fighting Katerea Leviathan, Harry appeared and his first greeting was a literal firestorm that engulfed the Leviathan descendent.

Katerea shrieked as the flames washed towards her. Then the faded Ouroboros snake tattoos that were inscribed into her flesh began to glow a sickly resplendent green. The insidiously seductive power rushed through her veins, her sigil appeared surrounding Harry and a series of colossal explosions, each one louder than the next impacted into Harry.

"Miss Gremory, will he be alright?" Baraquiel rumbled to Rias as she and her peerage moved closer to her brother.

"That's…either seriously injured him or pissed him off. Harry…Harry is tougher than he seems. I'm putting money on loss of a partial limb and or set his power-level to nine thousand or above." Neville replied.

However, Azazel blanched "I'll say near death…Unfortunately, your friend has bitten off even more than he could possibly chew. Yes, I watched his trolling of Riser Phenex and found it impressive. Unfortunately, Miss. Leviathan has entered a pact with the Infinity Dragon, Ophis."

Neville stilled "As in 'I laugh at Limit and the Infinite and I grieve at the Dream' that Infinite?"

Azazel nodded "Interesting you know the Juggernaut Drive incantation."

"Harry gets drunk, mumbles things and wakes up in weird places…It's part of the task of keeping together."

At that point Harry came crashing down, his bronze coloured armour falling off him. He was a mess! Half of one leg was gone, one arm was completely gone at the shoulder and in three parts. There also appeared to be his ribs, some of them were sticking out of his back.

Harry hit the ground, bounced twice and leaving a small set of craters. At this point, Irina and Xenovia sprung into action. Although they'd been dealing with Kokabiel and Katerea's minions effectively. Excalibur Mimic, an endless blur of shapeshifting ability slashing, slithering and slicing through the air like a spectral snake; moving like the bow of a violin being played by Mozart.

In contrast, Excalibur Explosion slammed into Kokabiel's wings with a deafening explosion "Impressive, Xenovia Quarta. Very impressive skill with that large hunk of metal called Excalibur Destruction."

Xenovia growled "I'm not just a wielder of a hunk of metal, as you call it…Now let me show you: Oh Peter, Oh Bascillia and Dionysis and the Blessed Virgin Mary, I ask you please hear my prayers…" Kokabiel watched as a glimmering cream portal opened and a sword hilt bubbled out; shackled and chained "…In the name of the Saint living within this blade, I hear by set you free!"

Matthews had darted forwards with Sirius and Remus and began bloomed and billowed as the Master Magician tried to heal the broken magician "Lad, you've done bloody brilliantly."

"I…feel like I done goofed." Harry rasped as he looked at the sallow faced mage.

"Will not lie; you're not in the best of shape."

"Cel?"

"I'm afraid, even though I could and I more than likely would be able to save you…I wouldn't be able to as Dragonification even on a partial limb takes a lot of energy. To replace an entire arm and half a leg, would more than likely kill you in your present state."

"And…any sort of witty remark or help for this situation?"

"You've got the Pair Dadeni, Cauldron on Rebirth and the Cauldron of the Dagda."

"Let me guess, that's gonna kill me to summon it…"

"Yup."

"I'm BOAKYAG aren't I?"

"If by BOAKYAG: Bend Over and Kiss Your Ass Goodbye. Yes, yes indeed."

Harry looked at Sirius, who was fighting back tears "Harry, you've gotta fight."

Harry grunted "Sirius…Get me up. MacGregor, stem my bleeding…I'm going to do something stupid."

As the two did so, Sirzechs moved forwards "Harry…"

"Sirzechs, does Serafall have a space in her Peerage?"

"Aye…You're not are you."

"I'm…a…troll. To die trolling is the perfect troll. Is this a troll which I see before me, the grinning loon toward thy face?'" Harry gargled, spitting blood.

Lupin and Sirius both shook their heads, Harry had always been entertaining; but even as he headed towards Death he was still trying to laugh. "Seems I'm playing a tough a crowd…Alright, you inglorious basterds asked for this!"

"Cheer up, Uncle. Cheer up, Sirius…Some things in life are bad. They can really make you mad, others just make you swear and curse."

Susan Bones deftly decapitated a minor devil and sent the entrails into Harry "No! Harry, Grandmaster Troll; you are. Undisputed Magister of Pandemonium, Mayhem. The Lord of the Horrible Horrendous and Impractical plans. You're even the Cackling Custodian of bad jokes and even worse temperaments, but none of these titles or anything permits you from singing 'Always Look on the Bright Side of Life' when you're at deaths door. That's OUR JOB, you NAUGHTY BOY!"

"Yes, Mom."

"Besides, Harry…you've not taught Hannah and I the whole Spanish Inquisition joke yet."

"Harry, don't you fucking, dare." Thundered Seamus as he dropped a perfect circle of 'Brigit Fire' around him to act as a holy shield.

"I'll nail it to your door, Susan and Seamus, as form of protest much like a Protestant…Oh Yahweh, my guts feel like raspberries and we've not had anyone get turned into the worlds whiniest lunchable."

Xenovia swung Durandel at it carved into Kokabiel electing a scream of pain "Is HE always like this? Talking utter trash, throwing spells that disobey conventional magic like candy? Just generally being annoying?"

"No…Normally he's worse." Rias commented flippantly.

"Why in The Lord-Of-The-Bible's name do you employ him? What purpose does he bring to you and your team? How do you even stand him? Where did you find him?"

It was Akeno who answered as she and her father combined their lightning to bisect three unfortunate familiars. "Why? Because he's straight forward and thus easy to predict and therefore manageable. What purpose? He brings clarity and through being him, he allows us to develop ourselves. Then there's the fact that he's handy in a hazard. How do we stand him? Ply him with alcohol, good food, good company and generally treat him like a person. He's got baggage, he's got no problems with helping us with our baggage and Peerage collective problems but in his words 'I'll massage your backs, providing you massage mine'. He treats everything we do as Newton's Third Law of Motion or Law of Equivalent Exchange. As for where we found him? In school. He came to us, enflamed a family situation and then when Riser Phenex showed up; started trying to annoy and piss of Riser, to the point where Harry got himself invited to a fight and well…"

Xenovia giggled "Did this…? Mass mayhem and annoyances?"

"Yup. Stupid magician. For all his shortcomings and annoyances, he's the very best at what he does. The cool thing, he tells us what he's bad at, but is willing to adapt and or apply his massive power base to whatever needs doing. He's upgraded my gloves; nothing much but allows them to store additional power and gather power based off my Rook piece." Koneko explained.

Xenovia's eyes widened "He can alter the very thing that makes you a Devil?"

"No…Harry's said 'ain't no touching that shit with ten-foot pole. Soul tampering makes me uncomfortable.' He was drunk at the time." Issei said as another presence appeared on the battlefield.

"He's always drunk, Issei…The quicker you realise Harry whenever the situations heading towards his specialisations is drunk…the safer you are." Hermione chipped in as she looked up.

"What is that?"

Serafall looked up, "That's the Vanishing Dragon…Harry…" She turned and turned pale.

"Excuse me Leviathan…I'll be back, I've got a Dragon to save. I've always wanted this particular Dragon." With spectacular blast of ice magic, Katerea was launched backwards as Serafall descended and in her place stood in a respledant golden version of the Scale Mail with twelve Black Wings was Azazel.
