XV: Wrapping Things Up

Harry casually summoned an orb of magic, then with pinpoint aim launched the sphere at Kokabiel. The aura of magic that thrashed, roiled and bubbled around the Warmonger; flared up turning Kokabiel into a shadowy mass and magnifying the entirety of Kokabiel's glittering mad ruby eyes.

"You think…" Mocked the Fallen Angel only for the orb to erupt into a blinding silver light, the silver light manifested into a majestic patronus.

"Prongs…ride." Harry instructed before he turned to the stunned Sirzechs and Serafall; upon making eye contact with the Leviathan, the subtle message was clear 'How do you want to do this?'

"Hadrian…take him down. That is your prime directive by Serafall Leviathan." Serafall commanded, gone was the laid back bubbly Mao but in her place was one of the Four Aces of the Anti-Satan Faction.

Harry grinned, he retracted his devil wings and concentrated then he began to speak. The noise and sounds that came out of his mouth sounded remarkably similar to William Henley "Out of the night that covers me, Black as the pit from pole to pole, I thank whatever entities may be for my Unconquerable soul. In the fell clutch of circumstance, I have not winced nor cried aloud. Under the bludgeonings of chance. My head is bloody, but unbowed.Beyond this place of wrath and tears. Looms but the Horror of the shade,And yet the menace of the yearsFinds and shall find me unafraid.It matters not how strait the gate,How charged with punishments the scroll, I am the master of my fate,I am the captain of my soul. BALANCE BREAK: PRIMAL AVALON KNIGHT!"

Harry's werewolf form appeared in a moonlight silver avatar, that rapidly solidified into a mass of black fur and muscle; then the unmistakable armour of the Balance Breaker of the Red and White Dragon Emperors formed around the werewolf with streaks of deathly emerald green and red and gold flowing over the bronze coloured armour and as the wings appeared, they were draconic in appearance but were in fact black as the Devil and Fallen wings. Harry growled, then kicked off the floor opening his wides as he took to the sky.

As he did so, he clocked Kokabiel casually smashing a white version of Issei about. He vaguely remembered Cel informing him of that this kid was the White Dragon Emperor.

"So, you're back for more." Kokabiel mocked through his mass of magical power.

Harry didn't respond as he blurred, Fragarach was in his hand along with Excalibur Nightmare "You have it! GIVE ME EXCALIBUR!" Shrieked Kokabiel sounding more and more like a deranged child.

"Come and take it, Kokblock." Harry growled, thankfully the eternal dragon of his family came with an omniscience of language. Thus, very helpful translation services.

"Hermione, what's the best way for dealing with constructs?" Harry yelled as he decided, if he couldn't brute force his way through his opponent. He could and would outmanoeuvre and hopefully outpace his foe and get him when his guard slipped.

"Hit him with fire…Harry, why didn't you hit him with fire or even the Jackal…"

"Because, the, Jackal was only meant to be used to utterly troll that prick Phenex. Which I did most remarkably if I do say so myself Lady Rias, Lady Leviathan."

"It's Serafall, Hadrian. Anyway…bring me some Crow-pie." Serafall called.

Harry turned to Kokabiel, "The Lady wants Crow-pie…then Crow-pie she shall have…Now, a little bit water magic." Kokabiel watched as the formerly dry battleground began to release water and soon enough a deluge was cascading around them.

"You pitiful, insignificant devil insect! You think that RAIN can stop the Angel of the Stars?"

Harry snorted as Fragarach extended into an absurdly sword that the Warmonger only realised was a Zanbato. His eyes narrowed as water began to coat the blade "What paltry elemental trickery is this?"

"This is the Cackling Answer, Warmonger. What do you know about the elemental cycle: fire, wind, lightning, earth and water?"

"One is weaker than the previous and stronger than the former, why?"

"What happens when you combine them?" Kokabiel began running through the various combinations, his eyes widened as the water-coated Zanbato began to sparkle and crackle as lightning began to meld with it.

"Oh shit."

"Oh shit is right, Kokblock. Pandemonium's Tricky Storm Answer!" Harry yelled bringing the blade crashing down onto Kokabiel, Fragarach sundering the light weapon and then the wings that had been flung up to prevent his attack, fell apart. This, this, very moment was why Fragarach; sword of the Mannanan Mac Lir, the Answerer or Retribution was designed.

Yes, armour and wings fell before it. For all of Kokabiel's famed durability, fighting Devils, Angels, His Own Brethren and those pesky Human rats. There spells and attacks had gradually whittled down his defences and that infernal sword Fragarach had done the most direct damage. There was a reason, why it was called a Psuedo-Longinus.

"Sleep in terror Kokabiel, allow your dreams and aspirations to turn to dust as the Nightmare weaves its terrors." Harry chanted as the rapier began to give off a dark purple glow.

Kokabiel screeched in terror as a seductive slate blue tendril caught Kokabiel in the head. Kokabiel stopped, the nightmare that surfaced in his mind effectively paralysing him. Then Fragarach moved and with precision Kokabiel fell into six pieces: head, upper torso, lower torso and legs; then the torso sections were cut in half again.

Azazel had during this resurrection of Rias's Mage into the service of the new Leviathan. The blood descendent of Leviathan quickly fell to him and quite frankly his experience and ability to swap between various light-weapon fighting.

He looked down to see Vali was slowly recovering from being slammed into the ground by Kokabiel. "Well, that kid's gotta learn…Will be interesting to see him throwdown against the Custodian and the Red Dragon Emperor." He murmured to himself.

(Vali)

Vali grunted. He'd been given one job, that job, bring down Kokabiel. He disagreed with his foster father about peace; if there was peace, how could he truly test himself? "Vali, there is a time and a place for everything. As of right now, you are in no state to fight the Custodian."

"Custodian? As in the mythical defenders and bearers of Old Religions?"

"The very same…Although this one is the Custodian of Britannia. One of the last places where the Pantheons managed to fight all Three Factions, not on an equal footing, but fought them effectively all the same."

Vali dismissed his armour, although he kept his Sacred Gear on display.

(Harry)

"Do we stand a chance?"

"Potentially. Some Divine Dividing wielders are more proficient than others. Considering what happened just now with this kid and Kokabiel…He's probably got an overinflated sense of skill; due to how the Divine Dividing works."

"Naturally." Harry replied, as he forced himself out of his werewolf form.

"Vali, calm." Azazel instructed. The newly named Vali, nodded at Harry who himself returned the nod before dismissing his armour. The two teens stared each other down, before Vali nodded and turned then headed back to Azazel.

Harry turned only to find Akeno soaring into his chest. "I thought you were dead, when Kokabiel cut you down. What were you thinking? Why did you think, you could take Kokabiel?"

"Kokabiel's a shit shot. The majority of my images came from my dynamic embrace with terra firma. I've had worse injuries; I mean I've been de-boned…lost all the bones in my body you perverted woman. As for the latter parts…I wasn't. If I had, Kokabiel should have been dead the moment I hit him with my blasting hex."

"Fallen Angels, Angels and Devils have a magical resistance that grant human spellcasters a disadvantage, in fact everyone a disadvantage, when fighting them." Rias explained.

Hermione turned on the redhead "You knew this, and you neglected to tell us?"

Rias stepped backwards before her temper flared and the power of destruction welled in her hands. "Rias, dispel your attack. You're out-gunned, outnumbered and more than likely outmatched." Harry growled.

"You're meant to be on my side! You signed a pact to be my magician."

"When, I was human…All pacts and contracts I made as a human are null and void. Furthermore, my directives given to me by Serafall Leviathan; whom brought me into her Peerage; told me to be myself. So, Rias Gremory, Heiress of Gremory are you willing to cross me? The mad mage of House Potter, the Troll of Phenex." Harry retorted as he stepped between Rias and Hermione.

Rias faltered. Harry was right, he had walked right through Riser Phenex and his Peerage, completely ignoring the Phenex's magical resistance. If he did that to Riser, a man twenty years her senior; what chance would she and her peerage, her friends and servants, have? "My apologies, I thought I'd briefed everyone effectively."

Hermione bristled and turned to Harry "Did you teach her how to brief and de-brief?"

Harry snorted "Nope. Too busy getting Akeno flustered and annoying the owner of the Kuoh Territory."

At that Sona, who'd just arrived with her peerage sighed "Is everyone okay?"

"Aside from now being in charge of the hops in a brewery, and only having one hand on any sort of situation, I'm good. Punctured lungs aren't anything to giggle at."

"Oh by the Mao, you're insufferable." Yura stated.

"Oh hey, Yura…If I'm insufferable as I am, wait until you know what my three orders are." Harry retorted with easily the biggest shit-eating grin on his face.

It was Saji who put the pieces together first "You done goofed…fighting Kokabiel, ended up getting converted into a Devil…Not Rias and certainly not Sona, so someone powerful…I'm going with Serafall Leviathan. She's told you to in essence do what you've been doing before hand and look out for Sona?"

"In essence. House Sitri and House Leviathan have access to my lacksidisal, whimsical ass along with my drunken stupidities."

Saji looked at him "One scaled destructive idiot to another, can you help me?"

"Help you with what?"

"Be well…more like you."

It was Seamus and Neville who swiftly interjected "No, you don't want to be like Harry. Harry will say never be like him. But you want to know more about being a dragon, us Wanded Spellcasters are intimately familiar with the disasters of Dragon Training. Harry'll help you but we're going to be chipping in as well. We're gonna make you everything Harry is, without the crippling side-effects."

"Everyone, it might be best to sort out the allegiances of our invaluable allies at later date. Can we please organise this treaty to achieve what we intended before the dimensional bubble breaks completely." Sirzechs stated.
