Gaming With A Keyblade(DxD)

*WHAM!* 

Koneko delivered a punch sending a gigantic three headed canine flying back. 

"Thanks Koneko!" Said Issei with a grateful smile on his face.

[BOOST!]

Right after the meeting with the two exorcists she decided to help Kiba get his revenge by creating truce said exorcists. It ended all well except for Kiba's disappearance and Issei getting nine-hundred and ninety nine spankings from Rias.

They separated from Irina and Xenovia, using Irina as bait they drew the Gremory and Sitri heir. 

But now Kokabiel decided to attack the town, trying to kick off another great war. Thanks to the Sitri peerage setting a barrier around the school they can fight without worry.

This went from trying to stop Kiba from becoming a stray by helping him destroy the Excalibur's to now trying to save the town from being destroyed by a fallen angel asshole. 

This entire situation was just shit! 

She jumped out of the way of one of Cerberus's many attacks. She won't be able to dodge or hold them off like this much longer.

When is the perv going to stop Boosting and where the hell is Kiba?! He should be able to sense the gigantic fucking barrier around the school. 

"Kyaaa!" Shouted Asia as one of the three headed hounds pounced upon her. 'Crap one got out of my sight!' thought the petite girl as she ran towards Asia ignoring the other Cerberus's. 

"Asia!" Shouts Issei he ran towards not caring if the [Transfer] will reset.

*Wang!*

With a swing of her blade the Cerberus head was sliced off cleanly.

"Xenovia!" Celebrated Issei as the blue haired exorcist smiled at him. 

"You look like you need some help." 

In the distance watching the battle from afar was Sethanel. Under a small but a high level illusion and barrier. 

He watched the battle with a smile on his face. Until the moment when Kiba showed up and confronted Valper Galilei, his smile dropped completely. 

"We believed we were serving the Lord! We bore excruciating pain! Yet you…Materials?... Dispose?" said Kiba as a look of absolute despair appeared on his face as tears welled up in his eyes. 

*Tik Tink!*

Valper threw a piece of blue crystal at Kiba and told him.

"Take it if you want. We have the technology to mass-produce even more crystals." Yuuto went to his knees and picked up the crystals with both his hands then clasp them together, holding it dearly. 

"I've…Always…always wondered if I deserved to survive that day." With a soft blue glow many children appeared around Kiba. "Many of them had much grander dreams than I did. Many of them wanted to survive even more than I did. Do I deserve to live in peace?" He asked. 

"Of course you do!" Shouted Seth as he appeared behind Kiba placing a hand on his shoulder. Looking behind he saw Seth along with his comrades.

"Hoo!" Said Kokabiel intrigued on who this insect is. 

"Cooper-kun!" Said Issei in shock. 

Rias and Akeno were also shocked they didn't know how he was here. Koneko just stood there not knowing what to do or think. 

"Just look around you man, these guys' souls came out just to meet you again with smiles all on their faces! I bet these guys all sacrificed themselves to save you didn't they? So don't just live for them man, but also yourself too!" 

Kiba didn't know what to say but hearing Seth's speech the souls of his allies smiled even wider than before. They started to fly around Kiba and Seth. It was beautiful, Xenovia and the Gremory group had no words.

The souls floated around Kiba and Seth as they gave their friend a last bit of advice before they passed on. 

"Don't worry…"

"It's okay…"

"I'm not scared, even if God doesn't exist."

"It doesn't matter if God doesn't exist…"

"Our hearts will forever be one!"

"Yuuto you have so many new friends."

"Cherish them."

"Protect them."

The Knight of Rias Gremory smiled, tears streaming down his face as he muttered. "One." 

"Oh man I can't hold back my tears!" Said Issei.

"My friends never wanted me to seek revenge. They never did. But nevertheless I must slay the evil before me!" 

"I must stop…" A Gremory magic circle which materialises a sword which he grabbed. "...anyone else from following my path." He slowly walked to Valper, sword in hand. 

Valper, like the coward he is, took a step back and in fright called for his Excalibur wielding attack dog. "Freed!"

The maniacal priest jumped in between Kiba and Valper.

"...I will become a sword. My comrades. My comrades who have merged with my spirit. Let us overcome it together. The feelings we couldn't say back then! The wishes we couldn't fulfil back then! Right now, right here! I shall become the sword of Buchou and my comrades! Please respond to my feelings now! Sword-Rebirth!!" 

Raising his sword to the sky a pure white holy aura and pitch black demonic aura surrounded his sword and swirled together melding with each other creating a sword which was half holy and half demonic. 

"Balance-Breaker" "Sword of the Betrayer". 

Kiba ran towards Freed. With his trait as a "Knight" in full throttle! Freed tried to grasp his movement with his eyes, but he got out of his excommunicated exorcist's sight by doing a few feints. 

*GINNNNNNNNNG!*

Kiba's newly made holy demonic sword clashed with Freed's Excalibur but even so, the silver haired stray exorcist managed to block his strike. 

'Even with Kiba's power boost, he can barely keep up with Freed, Valper is an incredibly smart individual, he managed to fuse four Excalibur's together even if it could be done a bit better. Because once the sword is broken that's it. The four cores aren't even fused that much.' Thanks to being a master alchemist and using the observe skill on both Valper and the merge Excalibur along with every other holy blade here. 

He now knows how to perfect his holy sword creation craft even more. All he needs to do now is to see Durandal. 

What the hell!? Did Freed just seriously just turn the blade of his sword invisible!?

Why not turn his entire body invisible and fake out Kiba with Excalibur nightmare illusions and finish him? And why did deactivate the invisibility and he began to morph the blade? 

WHY DIDN'T HE JUST MORPHED THE BLADE WHILE IT'S INVISIBLE?! IS THIS MOTHER FUCKER EVEN THINKING STRAIGHT!?!?!

Wait…. 

He isn't.

I forgot that he's a psychopath. 

Seth calmed down.

"Okay that's enough of that." Activating [Rabbits Foot]. He vanished and appeared between Kiba and Freed. 

Said exorcist was bitching and moaning about why the Excalibur didn't let him absolutely curb stomp Kiba. 

"Why!? Why isn't it hitting!? You are supposed to be the unrivalled holy-sword-sama, aren't you!? Weren't you supposed to have lots of legends of being the ultimate sword!?" shouted the psychopathic priest.

However Seth appeared and delivered an uppercut from below sending him flying upwards.

Kokabiel's eyes narrowed at this, but his cruel smile didn't drop. 

He then grabbed the Excalibur from the silver haired priest's hand and looked towards Valper.

"Hey old man. You did a decent job fusing these together again, but with the way they were fused if the blade was destroyed it'd be completely useless. Not only that…" Seth ducked and elbowed Freed who managed to recover in the stomach then planted his foot onto the priest's back to keep him place. 

"This dumbass could only use Excalibur's abilities two at a time couldn't he?" 

Valper raised an eyebrow. "What are you saying? That my work was sloppy?!" His face set into a scowl after a years of researching holy swords and the blood sweat and tears he poured into it some brat was criticising his work.

He managed to fuse 'FOUR PIECES OF EXCALIBUR', any other faction would kiss the ground he was walking on to have him!

"Nope but it could be better. I'll show you."

"Oh?" Kokabiel's eyebrow raised. 'What are you going to do little insect?' he wondered. 

"Seth what are you doing?" Asked Kiba. 

"Don't worry about it bro! I got this just lemme me do my magic!" Said Seth with a wink and his usual.

Seth created two golden magic circles to which the merged Excalibur began to melt leaving its four cores.

"Damn you!" He shouted as his entire life's work was just undone in seconds. "Freed, get up and murder that bastard!" He shouted but the silver haired artificial human couldn't budge because he was under two times gravity.

"Lord Kokabiel, please do something!" He pleaded. But the fallen angel only waved him off. 

From above the skies stood a handsome silver haired youth wearing a leather jacket. He had two large white wings with gigantic blue feathers. 

'Well this is interesting? Guess I'll keep watching.' 

The three cores then began to glow in a pure holy golden light causing the devils to take many steps back, soon the cores began to.

Everyone watching, especially those like Valper and Kokabiel who understood the Herculean effort it'd take to pull something like that off couldn't believe their eyes. 

The cores merged and with an even bigger glow Rias and Akeno had to place a few barriers though Seth didn't forget to help which they appreciated as a magic circle of unknown origin protected them.

Soon appeared the same blade that Valper forged. He kept the design one of the strong points of the weapon. 

The blade had an even more intense glow, the holy aura was still many times inferior than the original, Kokabiel felt it he knew it. 

He smiled as he stood up from his floating throne in shock and both delight. This is turning out to be rather interesting. 

"The design was cool so I kept it." Said the keyblade wielder as he grabbed the handle of the blade.

"Seth, what are you?"

"Just a human magician, though it's not as impressive as Kiba's Holy demonic sword. The only way something like that'd be possible if…." Seth looked up at Kokabiel who flew down. 

"He's dead isn't he?" Asked Seth, honestly he just wanted to rip the band-aid off. 

Valpers eyes widened, he didn't just study holy swords but also holy energy. 

"*Chuckles!* I wanted to keep this a secret, but it's not like it matters much, I am trying to start a war. In the previous three way war not only did the original Four Satan's die but also God!"

The reaction all around was shock, Asia fell to her knees.

"Lies! That's impossible!" Shouted Xenovia. 

"The truth is that another big war wouldn't happen unless you do it on purpose. It means that all three-sides went through hell in the past war. Everyone decided that it was meaningless to continue having a war if the start of it all, God and the four Satan's, were dead. Even that bastard Azazel declared that 'there will be no second war' after losing the majority of his men in the war! It's hard to bear! It truly is hard to bear! To lower your gun once you already shot it!? Don't fuck around! If we continued on from there, we could have won! Even so, he...! Is there any value in fallen-angels who can only live by inviting humans who possess Sacred Gears!?" Kokabiel declared his argument strongly. The fallen angel's face expressed deep anger. So much so his fist was shaking. 

Asia covered her mouth with her hands, her eyes wide open in shock as her entire world crumbled under her feet, and her whole body shook. Even if she turned into a devil, her belief didn't disappear. "God doesn't exist? God...is dead? Then the love we were given by him is...…" 

Kokabiel answered Asia's question with a slight chuckle. "That's right. It's normal that there is no love from God and no divine protection from him. God is gone already. Michael is certainly doing well. He's taking the place of God and is taking care of the angels and humans. Well, if the 'system' used by God is operating, then the prayer to God, the blessing of God, and exorcism would function. But if you compare it to the time God was present, the number of believers decreased. That Holy-demonic sword brat over there was able to create the Holy-demonic sword because the balance between God and Satan broke. In reality, Holy and demonic powers cannot merge. If the ones who rule the power of Holy and demonic powers, God and the Maou, disappear, then lots of unique phenomenons occur."

Hearing this, Asia fainted. Issei ran to her side and caught her before she could hit the ground. 

Kiba looked at his Holy demonic sword.

"From here on out, I will start a war! I will take your heads as a gift! Even if it's only me, I will continue from where we left off! I'm going to show Sirzechs and Michael that we, the fallen-angels, are the ultimate beings!"

He then turned to Seth. 

"Now then human, why is it that you don't seem to care that God is dead?"

Everyone turned to Seth, who just shrugged.

"One, I never really cared about religion. I'm an atheist. Two there aren't many good Gods, you can fact check history itself, so I'm good not worshipping any. And three, the world is still spinning without God so it just proves to me he's an unneeded existence." 

"Bwahahahahahaha!!!" Kokabiel burst out laughing at Seth's answer. "So you hate the Gods then!" 

"Nah! Hating the Gods would be a waste of my life. Though the God of Bible was flawed on how he ran things, ya know Christianity caused the Dark ages of scientific regression and all, he did a lot of good. Honestly I'm kinda glad, thanks to him I have a lot of the people I care about." A large toothy grin appeared on his face.

Thinking about all the people he met he's incredibly grateful. 

"Hmph! You're an incredible guy, you know that? Why not join me?"

"Nah! As much fun as it'd be to fight in that war you want. Way too many of the people I care about are gonna die." Two magic circles appeared one above and below the keyblade wielder.

"A shame." Kokabiel released his aura and the air itself practically shook. He created two light swords.

The magic circle above descended while the other one rose, the two circles clashed and a large golden glow Seth reappeared, his entire body golden and wips of light of the same colour rose off his body. 

Seth's aura was clear; the power he now had was incredible. Kokabiel's smile widened. "An interesting trick, this must be some balance breaker of sorts. However, will it be enough!" 

The fallen angel Cadre deduced he had some sacred gear which gave him light manipulation abilities such sacred gears weren't uncommon such as the Starling Bows. 

Kokabiel unfurled his wings and dashed towards Seth at speeds faster than light. Seth smiled as he created a blade of light and began to dual wield as he clashed with Kokabiel.

The shockwaves nearly everyone flying, it shook the entire barrier causing the entire student council to almost lose focus. 

"What's that light?" Wondered Sona. 

Moving at speeds faster than combatant there can see Seth and Kokabiel took the skys becoming golden and black streaks from moment to moment while they clashed over and over, Seth managing to out skill the fallen angel who now had many wounds on his body.

Thanks to actually using all of Excalibur's powers he's not only hitting only air but also. 

"Nyanya!" Seth blew a raspberry at Kokabiel who didn't take that very well.

"Don't you dare mock me! Raaaaaggghhh!!!" 

With a yell he summoned multiple light spears and fired them towards Seth with a cheek grin he breathed in all light spears.

Summoning a magic circle at his mouth he fired a gigantic light beam which Kokabiel dodged but he sensed something from his back and ducked. 

It's thanks to his experience and incredibly sharp instincts that he gained throughout the hundreds of thousands of years he's the reason he was able to dodge that attack and the reason he's not even more wounded. He growled as he blocked a few more attacks from Seth. 

None of the strategies he's creating is working, he's never felt so trapped before. 

"That's an interesting sacred gear you have. What is it?"

"This ain't a sacred gear. I don't have any. This is just a spell I made."

"What!"

Hearing what he said everyone couldn't believe what he said.

"This is simply magic!" He said in shock.

"Yep! Now see ya!" Delivered a combo of sword slashes sending the rogue fallen flying into the school building.

*BOOM!*

"Oh crap! Gremory-san I don't have to pay for that do I?"

"Um! No, we'll handle it after." Replied Rias, hearing her reply Seth released a sigh of relief. 

"Seth watch out!" Shouted Kiba. 

Kokabiel appeared and bisected him from his lower body, with a cruel smile on his face. 

"Nooooo!" Shouted Koneko as absolute despair appeared on her face. Her senpai, her crush and best friend was just killed. She bit her lips as she looked at Kokabiel with all the hate in the world.

*WHAM!* 

A golden and glowing foot planted itself deep into Kokabiel's face. 

"Bahahahaha!Dumbass!" Seth smiled. 

"What the hell! He's cut in half, how is alive!" Shouted Issei.

"Hehehe!" Seth chuckled as he restored himself with his lower half. 

"Dumbass my body is made of photons you can't kill me! I'll just restore myself!" 

This was a unique ability of the spell he created elemental transformation. 

"I'm basically a Log-!" 

"Logia devil fruit user!" Interrupted Rias. 

"You got it!" Seth said with his smile. Though he was a bit miffed, she took his spotlight.

"T-that's absurd!...No, there must be a drawback to that spell." He calmed himself. 

"No it's why I skipped school yesterday, it was to deal with drawbacks. I can stay like this forever. Though with level 2 I won't be able to hold it for long." 

'What!' Thought everyone.

"Buchou I don't get it. Are magicians supposed to be that strong? And did he just say level two?!"

"Not necessarily Issei, it should take years to reach that level of power for a human. And by level I can only guess he had a stronger variant of whatever he is using." Replied the Gremory princess. 

Seth then dashed towards Kokabiel. "Sonic Splinter!" A number of after images could be seen Kokabiel couldn't keep up not only that thanks to the ability of Rapidly he was completely outsped. 

He realised Seth was just playing with him before. This fight was lost the moment his hubris allowed him to activate his spell.

*Shing!*

"Flying Cross Slash!"

A flying slash mixed with light and holy power launched towards Kokabiel, the attack engulfed the fallen, sending him flying down the ground.

For a moment he thought he saw the image of Vasco Strada.

'Vasco was a genius, this human, no I can't call that boy a human! He isn't even a halfbreed… I wonder what he truly is?' 

*BOOM!* He landed in a large crater where he lay defeated. The magic circle which was about to destroy the town has disappeared. 

Seth landed on the ground and looked towards Valper who throughout this entire exchange became increasingly filled with dread. 

Creating a magic circle, chains of light erupted from which now held Valper down "Kiba, you can have revenge now."

Kiba nodded and walked towards Valper and beheaded him. He finally got what he desired. What he used to desire anyway. 

It felt empty in a way. 

He released a sigh of relief. If he was still caught up in his revenge just what would've happened to him? He felt as if he still hated Valper as he did just a few short minutes ago, he'd probably feel even more empty.

Is that the end of his revenge? 

No there's still people out there using Valpers research. His journey isn't over yet. 

*BAM!* 

"Oof!" Seth held his stomach as he fell to his knees, Koneko looked at him with an angry look. 

"I'm sorry I worried you." He said with a smile, the petite girl then hugged him as tight as she could. A normal person would be dead many times over. 

*Cr-Cra! BOOM!* 

The entire barrier was broken and blasted down to the earth, it was the White Dragon Emperor, in his Balance Breaker. 

"Yo you must be the White Dragon Emperor!" Said Seth.

"Do you know me? It doesn't matter anyway. I'm here for Kokabiel, I was ordered by Azazel to bring him in. I'll also be taking him." 

"Sure take him though you can't really take him."

"And why is that?"

Seth's magic circle appeared below Freed and a spike of ice ripped through his body killing the bastard.

"Sorry but he's too much of a slippery bastard to let roam free."

"It doesn't matter, we can just rip whatever information we want out of Kokabiel instead." Why take info from a henchman when you can take it straight from the boss. 

(Are you ignoring me White one?) Said a voice from Issei's left hand. 

"The dragon can talk?" Rias muttered.

(So you were awake, red-one.) Albion's armour jewel was also glowing white. Were the ones residing in the jewels communicating? 

(We finally met, but in a situation like this That's all right. It's our destiny to fight one day. Things like this happen But white-one. I can't feel the hostility from you like before Red-one.)

(Your hostility is incredibly low as well. Looks like both of us have things that interest us more than fighting.)
