Meanwhile, as the Devils spoke with the Kaiju in Human form in Lilith, a certain war mongering Fallen Angel was in the middle of his own plans...

"At long last... my war will soon come, we Fallen Angels shall show out power and prove to both Heaven and the Underworld who is truly the most powerful!" Kokabiel said with confidence and pride in his voice, before he laughed a manic, blood thirsty laugh

"Hahahahaha!! You got that right boss! As long as I get to cut thos shitty Devils to pieces, I'm happy to work for you!" Freed Sellzen said loudly, his tongue hanging out of his mouth as he omagined the screamed of the Devils he would kill with a Holy Blade, and the reconstituted Excalibur as well.

Meanwhile, the Genocide Archbishop, Valper Galilei was working to fuse the stolen shards of Excalibur into one Holy Sword, which Freed would then wield for their cause.

"Heck, our new benefactor is also a hell of a boss to have, he actually encourages my way of doing things and the fact I enjoy fighting and killing so much!" Freed said as he hugged himself and started squirming in place with joy.

"Yes... I was quite surprised when someone of his power showed interest in restarting the Great war, but... considering his title, perhaps I shouldn't be surprised?" Kokabiel said with a smirk on his pale face as he relaxed in his throne, imagining the war to come, and him leading his fellow Fallen to victory over the Devils and Angels.

(But I wonder... if I restart the war, will "it" return again?) the Fallen Angel Leader thought to himself, as he frowned slightly and thought back to that day, the day he looked upon the deadly radiance of the Deathsong of Three Storms, seeing the utter destruction he brought with his own power, and witnessing him devour God...

Kokabiel felt some hesitation on his plan as he remembered that day, and the sight of the Golden Wings of Demise as they case their shadow over the battlefield, he truly hoped that their benefactor could turn the tide against the Golden Dragon of Devouring.

KUOH

A few days had passed since the Devils had sat down with (Y/N) Ghidorah, they had managed to convince him to stop his rampage for now at least, and... it led to (Y/N) and his brothers being very, very bored, Azazel often insisted on him getting himself a girl to entertain himself with, though none really struck the Golden Wings of Demise as interesting.

Right now, (Y/N) was walking in the town of Kuoh in his Human form, he was wearing his golden armour and cape as he walked and ignored the looks the few random Humans he encountered gave him, he was also aware that the Devils of this town could likely sense his power and that the Devils likely had agents watching him as he walked the Earth, likely afraid that he may decide to destroy this world.

As he walked he then saw a beam of light from somewhere in the city he was wandering, he looked to the light and sensed a strong Holy energy, as well as several smaller energies, it made him curious and so he started to follow those energies to their source, wondering if he may also have a fight coming his way.

As the kaiju in Human form walked away, the Devil assigned to watch him then turned away from the light and saw where he was going, they then started to panic, he was heading right to Kuoh Academy!

"I need to contact Lord Lucifer immediately!" the Devil said as they conjured a magic circle and made contact with Sirzechs, they had to get involved, before Rias, Sona or their peerages became the target of his rage.

(Brother, why are you following these energies? They are so weak, they wouldn't be any fun to fight) Ni complained in (Y/N)'s head, wishing for a proper battle like the one's before.

"I'm bored... these Humans have nothing of interest to me, and perhaps watching these energies struggle against each other would entertain me" (Y/N) replied to him, walking closer and closer to the school in question.

(Pah! I'm telling you, it will be a boring display...) Ni grumbled in annoyance.

(Brother, maybe we could try what that man with the Black wings suggested?) San/Kevin said in (Y/N)'s head, causing him to pause his walk.

"You mean indulging myself on one of these Females, he's so insistent I try breeding with?" (Y/N) asked his more happy brother.

(San! Why do you always have to suggest such foolish things? Why would he waste our time with such weak creatures?) Ni said to San/Kevin, sounding very annoyed by the suggestion he made.

(It could be fun! I mean, if our Brother is so bored then maybe it will be something to do until the time comes?) San/Kevin said to Ni, (Y/N) stayed quiet and thought more to himself, wondering if perhaps it would pay off to indulge in this?

He and his Brothers had been destroying planets and worlds for a long time, something to keep him busy until he grew bored and destroyed this world too could be a good thing?

(Brother, are you seriously considering this?! You wish to sully yourself and us by mating with these lowly creatures?!) Ni asked him, sounding angry and unhappy about the idea.

"It is something to consider but... only ones who meet our standards, not just any lowly insect will do... anyway, it would seem I have found the energies" (Y/N) said as he approached Kuoh Academy, ready to see who or what was fighting here, only to stop as he saw a barrier that was around the school.

As he stood at a part of the barrier, one of Sona's peerage, a young girl called Ruruko Nimura, saw him standing at the barrier.

"Hey! What do you think you're doing here? Get the hell out of here!" she exclaimed at the Kaiju in Human form, thinking he was a Human, until... she sensed the power coming from him, the power that make her start to tremble as cold sweat fell down her face, suddenly, all of the Devils in the School, as well as the Fallen Angel General sensed the new power that had arrived.

"M-Mistress...!" Tsubaki exclaimed as she went wide eyed in shock from the power she felt approaching their barrier.

"This power... who could this be?!" Sona said in a shaky voice, scared that this power may also be allied to Kokabiel, the rest of Sona's Peerage also felt this power, several of them almost falling to their knees from the pressure this power exerted.

"Look at that! The Cerberus... they're scared?" Issei exclaimed as the ORC, and Xenovia noticed both Hellhounds had their ears flattened as they shrank down, whimpering and looking around fearfully.

"Woah..." Koneko gasped as she felt shivers running down her back, her Nekomata senses telling her that they were all in great danger.

"This feeling of dread... what kind of monster is coming?" Xenovia said as she gripped the handle of her Excalibue Destruction tightly.

(This power... could it be him!?!) Kokabiel thought to himself as he looked up to the skies, his body trembling in a mix of excitement and fear, his memories of the Great War and the death of God resurfacing in his mind.

Back with (Y/N), he had a bored look on his face as he drew back his leg and gave the barrier a strong kick, causing a portion of it to shatter like glass, blowing Ruruki back several feet and slamming her against a wall, knocking the Female Devil out, (Y/N) then walked inside with a smirk on his face.

"The barrier!" Tsubaki exclaimed as they saw the cracks spreading rapidly, Sona then ordered her Peerage to add more power to the Barrier, quickly sealing the Barrier back up, but putting more strain on themselves from repairing the barrier and making up for the loss of one of their members.

(Y/N) continued to walk the rest of the way onto the Academy grounds, with Sona seeing him as he walked away from them, wondering if Kokabiel may have called in back up for this fight, Monster Zero soon reached the sight of the battle, and everyone then looked at him as he appeared.

"Well now, this looks like an interesting fight, anyone mind if I watch the show?" (Y/N) said as he approached the battle, allowing his power to show along with a toothy grin, showing no fear of the beings within.

"Who are you?! How did you get past the barrier surrounding this school?" Rias Gremory, a Red-headed Devil who was a member of the Gremory House asked the Kaiju in Human form, shocked as she felt the power coming from within him, sensing the Godly power he possessed.

"That doesn't matter, all that matters is that you foolish insects entertain us with this fight your having" (Y/N) said to her dismissively as he scanned the people on the battleground, looking very bored with who was gathered here, so far no worthy challengers, or snacks.

"Hey, she asked you a question asshole!" Issei suddenly exclaimed as he pointed a finger at the Human kaiju, who... just ignored the little pervert completely.

"He must be working with Kokabiel, another of his agents" Akeno said with a sadistic smirk on her lips, imagining the fun she could have making the new arrival scream for her.

"Well if that's the case we'll just kick his ass too, come on Ddraig, let's-HUH?!" Issei said full of confidence and bravado, only to see the Red Gauntlet on his hand vanish in a flash, Issei and his fellow Devils all looked very surprised and wondered what the hell was going on.

"Ddraig, what the hell man, why did you vanish?" Issei asked the Red Dragon in confusion, talking to his hand as (Y/N) watched him with a raised brow.

"Issei... you have to run" Ddraig said to him in a fearful voice.

"What?" Issei asked the spirit of his Sacred Gear in surprise, wondering if he'd just heard Ddraig correctly.

"YOU MUST RUN, NOW ISSEI! WE CANNOT FACE THAT BEING!" Ddraig shouted loudly, startling all of the Gremory Peerage from how scared he sounded.

"Woah, D-Ddraig, what are you talking about?!" Issei exclaimed to the small green magic circle on his left hand, which Ddraig used to talk to him.

(This person is making the Red Dragon of Domination scared? Who is this guy?!) Rias thought to herself as she looked from Issie to (Y/N) Ghidorah, who stood there looking at them all with a very bored look on his face.

"Hooh? Another shitty Devil for me to cut to pieces? It must be my birthday!" Freed said with a manic giggle as he pervertedly squirmed around, clutching his Excalibur tight as he fantasised about all the ways he would torture and kill each and everyone here.

(That Human is loud...) San/Kevin grumbled in annoyance in (Y/N)'s head, if he was out he'd likely be pouting at the loud, annoying little fool.

(And annoying...) Ni growled in annoyance, (Y/N)'s eyes narrowed at the loud, perverted freak, and planned to get rid of this pest, suddenly Freed sprinted at the Deathsong of Three Storms, with his Excalibur raised over his head and his tongue hanging out of his mouth.

"Time to die you shitty Dev-" Freed screamed before (Y/N) lazily raised his hand and channelled lightning into it, the energy charging up and taking the form of a spear, before he threw to bolt like a javelin right into the crazed ex-Priest's chest.

Freed let out a loud, shrill scream as the power of (Y/N) Ghidorah's Lightning surged through his Human body, the raw power of the electricity burning his body so intensely that his body turned into a twisted, blackened husk, still clutching the fused Excalibur in a death grip.

The Devils were frozen in shock at the sudden and horrific death, the smell of burning hair and flesh flooded the area, making some feel sick, the Devils and Humans then noticed the Cerberus were looking at the new arrival with utter terror on all three heads.

Rias felt a cold sweat running down the back of her neck, she also felt the God-like energy coming from the man, she wondered to herself if he may be a God from another Pantheon, come to join the battle?

Akeno was on guard from the display of power, she knew that her own Lightning, even the Holy Lightning she refused to ever use paled in comparison to the incantation she just saw kill that psychotic ex-Priest in one strike, though... she also found her eyes gazing over his well built form, and blushed as she imagined making him scream.

Asia was terrified of the man, after seeing him effortlessly kill the man who was part of her torment before joining Rias's Peerage, she felt conflicted, on the one hand he was a violent psychopath who had threatened to rape her, and was also part of her death at the hands of Raynare, but... it was also against God's teachings to take satisfaction in the suffering of others, then the stench of burnt hair and flesh invaded her nostrils, making the blonde haired former-Nun want to vomit.

Kiba's eyes widened in shock at what he just saw, that lunatic and his fused Excalibur shards had been giving him and Xenovia so much trouble, yet this unknown man just came strolling in and killed him with a single attack!

Koneko's legs were shaking as she looked at what just happened, her enhanced Nekomata senses were screaming at her to run, ran far away from this person and the destructive aura she could sense coming from his body.

Kokabiel and Valper paled considerably at what they just saw, the Fallen Angel Leader trembling in excitement and fear at the power he felt, even in this new form he knew who this was...

"Annoying insect... his buzzing was irritating" (Y/N) scoffed with a frown on his face, before he walked toward the burned, blackened husk that was once Freed Sellzen, and then reached out and tore the Excalibur Sword from him, taking the hand with it.

"H-Hey!" Xenovia said as she saw him take the blade, (Y/N) hummed and raised the blade up, looking at the chunk of hand-shaped charcoal that refused to let go of the handle of the Holy Sword as if looking at dirt, he gave the chunk a flick and it crumbled to ash and then looked at the sword in his hand.

(It feels like the old man we devoured before...) (Y/N) thought to himself as he looked at the sword with a neutral look, examining the sword.

(Perhaps there are more with power like that one?) Ni suggested with a smirk, if there were more of them, then perhaps he would have more food soon?

(Aw... it's not as shiny as when we use that power) San/Kevin whined, sounding disappointed from the sword not glowing.

(Y/N) sensed the power in this sword and... tossed the blade away with a bored look on his face, the Devils jaws dropped at what they saw and Xenovia looked outraged when the sword was carelessly tossed into the dirt.

"Such weak power, useless" he said as he turned looked up to Kokabiel, who flinched at his gaze, as Valper Galliel looked at him in utter shock and terror, he knew who this was and his presence was so intense the man contemplated ending himself to escape the heart stopping sense of dread he was being subjected to.

"Hey! That's a gift from God himself! You can't treat the Holy Sword Excalibur with such disrespect!" Xenovia shouted in outrage, seeming to have forgotten the power she sensed coming from him, at least, until he then turned his gaze to her.

"So many pests buzzing today... perhaps an extermination is in order?" (Y/N) said darkly, his eyes glowing with power as the air around the school suddenly thickened with so much killing intent that the two Cerberus yelped and ran to the borders of the barrier, planning to try and break through and escape this Alpha Predator, much to the Devil's shock.

"What? He's going to destroy the town too?!" Issei exclaimed in shock and anger as he got into battle stance, planning to defend his hometown to the death if need be.

"That man... Lord Kokabiel, it's him isn't it?! He's the one who-" Valper said in shock, before suddenly, a large Light Spear pierced his chest, killing the man instantly.

"Who are you? In the name of the House of Gremory I demand you name yourself!" Rias exclaimed as she pointed at the Devil with Three Heads, standing as if she were confident in her authority, however... that faltered when his eyes laid upon her now.

"A weak lower life form such as you, making demands of me? How laughable... you should learn not to make demands of one so far above you" (Y/N) said to her with a humorless laugh, before in a sudden flash of movement he hurled another Lightning Spear, which struck the ground where she was standing, sending her flying back into Akeno with her uniform destroyed and some severe burns on her skin.

"Buchou!" the ORC all exclaimed as they saw their King be attacked and thrown back like that, Akeno caught her, but the momentum was so great she was flung off her feet and crashed to the ground with Rias on top of her.

"Rias, are you alright?!" Akeno said as she sat up, wincing from her back roughly skidding along the ground, scraping at her skin and the remains of her Shrine Maiden outfit.

"Hold on! I'll heal her!" Asia said worriedly as she ran over to the two along with Koneko, and quickly started to heal Rias.

"You bastard! How dare you do that to Rias!?" Issei shouted angrily, though he was unable to do anything with Ddraig refusing to come out, when suddenly everyone looked to Kokabiel, who was laughing manically.

"Hahahaha! Yes ! That will bring the Devil King Lucifer here for certain! My War is getting closer to happening, and the very one who robbed these Humans of their master will be the catalyst!" Kokabiel declared loudly with a big, toothy grin on his face as he looked up to the red tinted sky.

"What? What is that supposed to mean?" Xenovia said as she looked up at the Fallen Angel with suspicion.

"Whoops, looks like it just slipped out... I'm so careless, well there's no point in hiding it anymore..." Kokabiel said as he covered his mouth, which was pulled into a smirk, before he faced all of the Devils and the lone Exorcist in the area.

"THE TRUTH IS THAT IN THE LAST THREE WAY WAR, GOD WAS KILLED ALONG WITH THE FOUR DEVIL KINGS!" Kokabiel shouted loudly enough for everyone to hear him, the Devils and Xenovia were floored by this new information, while (Y/N) just didn't care.

"N-No way... God is dead? Your lying, that can't be true!" Xenovia exclaimed in a very emotional voice, wanting to deny any of this was true.

"Back then the Devils lost all of their Kings and most of their high level Devils, the Angels and Fallen Angels lost almost everyone except for their leaders, Pure Angels couldn't increase their numbers and... pure-bred Devils are just as rare, aren't they?" Kokabiel said to them all with a shit eating grin on his face, enjoying watching as the information sank in for them all.

"It's not true... it can't be..." Asia said as tears built up in her eyes, not wanting to believe that the God she had believed in all along was actually dead the entire time.

"All sides were ruined to the point where they had to rely on Humans to survive... and the one who did it all, the one that killed so many of the three factions and also killed God and the Devil Kings? He's right there!" Kokabiel said as he swept his arm towards (Y/N) who stood there with his arms crossed over his chest, simply watching the dramatics unfold with a look of utter boredom on his face.

(These creatures are so boring! They stopped fighting as soon as we arrived!) Ni said angrily, feeling very annoyed with the let down from the show they expected and came all this way for.

(Why is everyone looking at us now?) San/Kevin asked, sounding confused as (Y/N) paid attention to the fight, and saw that indeed everyone was looking over at him in shock, fear and disbelief.

"Michael has been doing his best to hold God's system together, but he's been slowly losing control, some Angels fell after that battle, seeking revenge for the death of their Father and have fallen so far even Azazel refuses to bring them into the Grigori, performing some truly vile experiments, all in the name of killing that man there" Kokabiel said with his shit eating grin on his face still.

(A group who wants to slay us? Sounds interesting... hopefully they and whatever monster they make might actually be a challenge) (Y/N) thought to himself with a smirk on his face.

"That man... killed God?" Rias said as she sat up, looking at (Y/N) Ghidorah in disbelief, though... from the power she felt coming from him, she believed it... there was NO WAY they could win now!

But suddenly Magic Circles appeared between the Gremory Peerage and the Fallen Angel Leader, and from them emerged, Sirzechs, Grayfia, Serafall, Azazel, and a figure in White armour with Dragon-like wings appeared, they had come to help them!

"Kokabiel! Stop this mad plot of yours right now!" Azazel said with a serious look on his face, as Sirzechs and Serafall looked to (Y/N) Ghidorah with worry, but... also planned to not allow him to attack their beloved sisters or their peerages.

"I think not, Azazel, not now that my war is coming back... besides, my benefactor would be quite upset with me if I turned back now, it's time to start the second three way war! Go forth, Golden Dragon of Devouring! Sate your appetite upon these Devils!" Kokabiel said with a grin as he swept his arms toward the young Devils, however...

"Do not think you can command me... I am the Alpha and bow to no one!" (Y/N) growled as he turned his ire upon the fallen Angel and raised his power up immensely, Sirzechs and Grayfia quickly rushed to Rias and her peerage.

"Rias, come, we must get outside of this barrier, before it's too late!" Sirzechs said with a serious look on his face as he scooped Rias up into his arms, frowning at the state of his sister from this fight, feeling guilt that she had to fight a former Seraph alone, and ran into the Golden Wings of Demise.

"You too, Exorcist, we gotta go" Azazel said to Xenovia, who was still in disbelief at what she was told, gripping the handle of her Excalibur Destruction tightly in her shaking hand, the White Dragon Emperor watched this new face with intrigue, already planning to try battling him someday, unaware of the fact Albion, the White Dragon Emperor. was shitting himself in fear.

The newly arrived leaders gathered everyone together and teleported outside of the barrier, where they saw Sona and her Peerage were relieved by several other high-ranking Devils, powering and strengthening the barrier.

"B-Brother... who is that man?" Rias asked him as she looked up to her older brother as he carefully set her down, he looked to her and then let out a sigh as her Peerage also gathered around to hear this as well.

"Not now, sister.... I'm sorry but for now, we must focus on making certain the city isn't destroyed by those two" he said to her, before he sent Grayfia to add her own power to the barrier, if all else failed... they had to prepare a transportation circle to move them out of Kuoh, before it ended up like Kyoto.
