Alliance of Hell

Also known as the "Hell Disaster", this was the final battle that took place between 2 factions.; Team DxD and the Alliance of Hell which was formed by multiple Evil Gods such as Hades, Angra Mainyu, Aka Manah and a few others. After Hades had created a new London temple and used the Book of Lucifer to create 40,000 new Devils with only 2 possessing power equal to that of a Super-Devil. These 2 were known as Balberith and Verrine but Balberith was far stronger than Verrine. Hades believed with Balberith at his side, there was no chance for DxD for even he feared the Super Devils immense power which exceeded that of his own.

Main Offensive Team vs Artificial Devils and Grim Reapers
The main offensive team headed to Hades' newly created London temple as they engaged the massive army of 25,000 Artificial Devils and Grim Reapers. Kuisha Abaddon stated they would ultimately expect to face 40,000 Devils at maximum but Vali Lucifer believed the army could be anywhere up to 100,000 if not higher. All the teams went to their objective points and engaged the enemy. Issei and Vali activated their Diablos Dragon forms, Kio transformed into his Star Destroyer form and Dillon activated his Apocolyptic Thunder form to blow away hundreds of the Artificial Devils with a single attack. Regulus killed hundreds with his claws and fangs. He would later combine himself with Sairaorg to form his Regulus Rey Leather Rex armor. Sairaorg began punching the Devils away while Gomagog blasted them with his machine guns. Kiba activated his sub-species Balance Breaker, Glory Drag Trooper to attack and then equipped each warrior with his Demon Swords. (Balmung, Nothung, Tyrfing, and Dáinsleif). Ingvild Leviathan summoned a Water Dragon while Fafnir began attacking the enemy whilst also protecting Asia. Lint Sellzen burned many to ashes as Journey to the West began a rampage. Once the numbers of the Artificial Devils began to plummet Hades sent his massive army of Grim Reapers which numbered up to about 50,000. Kiba warned everyone to avoid their scythes at all cost. DxD slowly advanced as it suddenly began to snow which was caused by Lavinia's Balance Breaker; Assoluto Argento Mondo, which froze all the Devils and Grim Reapers into ice sculptures but it did not freeze any of her allies. However, a very powerful aura was suddenly felt across the battlefield as someone began walking past all the icicles; it was none other than Balberith, Hades Trump Card. Sairaorg informed Issei and Vali that they needed to go on ahead to stop Hades from creating more Devils while he would personally deal with Balberith. Issei reluctantly agreed as he, Vali, Fenrir and Gomagog all flew over to Hades location inside the temple while Sairaorg and Kiba prepared themselves. Dillon and Kio had noticed Balberith's presence but before either one of them could rush over to aid Sairaorg they were suddenly struck with a bolt of Lightning. Dillon managed to endure the pain but Kio could not and slowly fell to the ground. Dillon glanced around only to hear the loud laughter of an unknown person which caused him to look up into the sky. A human like figure with 8 Fallen Angel wings slowly descended from the darkened clouds. The unknown human like figure resembled that of a young Azazel which shocked Dillon. The Fallen Angel revealed himself as Azza and the two clashed with the Fallen Angel easily gaining the upperhand while Kio struggled to make it to his feet. Meanwhile, Balberith and Sairaorg began to speak to one another whilst also taking note of Dillon and Azza's mid-air battle. They agreed to a fair fist-fight as long as Sairaorg promised not to harm Verrine and Zeno which the latter agreed to. A loud clash occurred which entranced everyone on the battlefield as they began beating the hell out of one another. Sairaorg was forced to activate his Breakdown the Beast armor but Balberith still managed to destroy some of the latter's armor without the use of his immense Demonic Power. Kio shortly made it to his feet and flew into the air only to be met by a massive group of Devils and Grim Reapers to which he wiped out within minutes. Dillon and Azza continued their battle until the Fallen Angel managed to severely wound the latter. Azza while not as physically strong as Dillon, he knew how to make the most of his abilities by attacking pressure points as well as analyzing signs of possible weaknesses. Dillon tried to find a way to break through Azza's incredible defense but nothing seemed to be working. Dillon tried to summon lightning but Azza used his axe to distort the lightning until it faded. (INSERT). A smirk appeared on Azza's face until Dillon finally managed to land a decent strike and overpowered the latter. He struck Azza with a massive cosmic infused lightning bolt which drove Azza into the ground. The latter managed to get back up but Dillon who was running out of ideas quickly summoned Asi and combined his Cosmic thunder with his blade. He flew towards Azza and engaged in close combat and using sheer force he swiped away the axe Azza was using and stabbed the latter. Azza stumbled backwards but due to his astounding knowledge of magic he instantly healed himself and activated what he would later call the Anchi System. Suddenly all of Dillon's powers began to fade, he tried summoning magic, he tried summoning thunder, he even tried summoning cosmic energy but all of these attempts were prevented due to the negation effect of the Anchi system which allowed Azza to decrease or increase the powers of others along with manipulating said powers. Having found no other alternative, Dillon charged ferociously at Azza but he was quickly sealed inside a barrier. Kio had noticed the carnage after defeating the remaining Devils at his location and quickly flew over to aid his brother. Azza dodged Kio's sneaky attempt at a clothesline from behind and activated a horde of magical spells which drove the latter into a nearby building. This gave Dillon a chance to break out of the barrier but Azza quickly activated another sealing spell that far exceeded the power of the previous one which prevented the latter from escaping for the time being. Azza then activated a powerful but forbidden Illusion based spell which put Dillon into a deep sleep as he collapsed onto the ground. Kio emerged out of the building and engaged the latter in close combat but was struck down by Azza's mighty axe which he summoned by simply opening his hand. Kio struck the ground hard but he made it to his feet very quickly. However, he witnessed Azza activating his sup-species Balance Breaker. He slowly became enveloped in a silver like draconic armor that almost mimicked Kio's Star Destroyer armor but a shade darker and much more armor. Kio charged at the latter but was effortlessly knocked down by Azza's immensely powerful magic which began to slow Kio's mobility. Eventually the latter could not move an inch but he quickly punched through the magic circle below him and broke free. He hurled a gigantic wave of his demonic aura towards Azza who used advanced teleportation magic to hurl the energy directly back at him. Kio moved out of the way just in the nick of time but in doing so he had actually broken the barrier that had Dillon trapped inside who was still fast asleep thanks to Azza's Illusion Magic. Kio was then struck by a horde of lightning bolts that did a massive amount of damage and destroyed a small portion of his armor. As he continued to be struck with said lightning the pain grew increasingly worse but Kio got an idea. He slowly fought through the immense pain and grabbed ahold of Dillon which somehow made him regain consciousness. He sat up seemingly confused until he glanced around and remembered where he was. Lightning began racing through his body as he vanished from eyesight only to appear in front of Azza who had somehow managed to summon a small barrier to deflect Dillon's lightning fast attack. Dillon flew around the later at speeds far beyond what the eye could handle which made Azza realize he was in danger of being taken captive. Knowing he lacks the skill to take on both a Heavenly Dragon and a Super Devil, he opened up a teleportation magic circle but Dillon appeared directly in front of the latter and struck him hard in the face with a powerful left thunder punch that sent Azza down into the ground with tremendous force. Dillon informed Kio that he needed to go aid Sairaorg and that he would deal with Azza personally. Kio hesitantly agreed to the latter's order and flew off to Sairaorg's location. As Azza slowly began to get up he started laughing which confused Dillon. However, the latter informed him that they were brothers which drove Dillon into a state of rage. He absolutely could not believe such information was true which caused him to shoot a thunder bolt directly into Azza's right arm thus destroying it. However, the latter continued his monologuing by asking Dillon if he ever wondered why he could do things no one else could. Why he could hear people at great distances or understand things from a different perspective. The latter once again struck Azza with a bolt of lightning whilst screaming "Shut Up!!!" but Azza just kept walking forward with a smirk. Dillon cast one final bolt of lightning that was 10 times bigger and stronger than the previous bolts that Azza could've easily blocked but he allowed himself to be struck. A huge explosion occurred around the pair and as the smoke cleared Azza can be seen activating a regeneration spell that easily repaired all of the damage that had been inflicted. Dillon became so frustrated that he began absorbing a massive amount of energy but this was a huge mistake as Azza activated his Anchi System once again which prevented the latter from obtaining any more power. Azza then proceeded to activate a combination of Elemental and Fallen Angel magic spells which he simultaneously used to attack the latter. Dillon managed to avoid a few of the attacks but he quickly became overwhelmed and was blasted into a car which was crushed in half. The latter stumbled as he made it to his feet but he would quickly be smashed in the face with Azza's axe as he gets flung down the street leaving a long trail of broken cement. Dillon becomes enraged as he flies into the air with extreme speed and chases after Azza who appears to have already summoned a wall of ice which allowed him to appear behind the latter and sneakily attempt a strike aimed towards Dillon's neck. The latter easily moved out of the way grabbing the axe and attempted to pull it away from Azza but he lacked the strength to physically overpower the latter. They engaged in a flurry of close combat which eventually ended with Dillon landing a perfectly placed kick to Azza's ribcage followed by a preciously placed cut from Asi to the leg which he summoned through his left gauntlet. Azza summoned his regeneration magic once more to heal but Dillon quickly attempted to tackle the latter. Azza used his fallen angel wings to cocoon himself while he regenerated but Dillon broke through Azza's defense with a cosmic infused lightning bolt. Dillon began to get angrier and angrier as he engaged the latter and threw punches with tremendous force as well as speed. He finally overpowered Azza and sent him flying into the ground below thus causing an explosion. Dillon roared loudly, as he summoned a massive thunderstorm infused with his cosmic powers but Azza easily negated the storms power thanks to his Anchi system but Dillon at this point just lost it. His body began to negatively react to the massive power that was being contained and thus he had no choice to but to release it through his Expel ability which caused a massive shockwave throughout London. As the dust settled and the smoke cleared, Azza released a barrier he had surrounded himself with which shocked Dillon as he could not inflict any permeant damage on Azza at all. Having run out of ideas, Dillon summoned Asi into his hand from the ground below and furiously charged at Azza, desperately trying to land a strike but Azza effortlessly avoided and evaded every attempt at a strike. A few moments passed with Dillon eventually becoming exhausted as Azza struck him in the abdomen with his axe which caused Dillon to cough up blood. Azza then raised his axe into the air and summoned a massive thunderstorm and struck the latter with a lightning infused strike which hurled Dillon down but he managed to stop himself from crashing into the ground. Azza appeared behind him and missed his next strike as Dillon flew to the right and performed a deadly combo that knocked Azza down. Dillon tackled the weary Azza and began punching him relentlessly but Azza struck a few pressure points which immobilized the latter for a few moments. Azza had bits and pieces of his armor broken all over and small cuts as well as bruises all over his body. He acknowledge his brother's strength as he continued his assault on the latter. Dillon began coughing up blood as he was beaten over and over until he managed to grab ahold of Azza's axe and knock it away but Azza used his hand hand combat skills to strike Dillon continuously until he forced the latter back a few steps. Dillon began to bleed all over as Azza finally brought the latter to his knees and summoned his Axe. Having been brought to the brink of unconsciousness, Dillon used the last of his strength to summon an unknown magic circle that froze Azza's movement completely. The latter tried to move but Dillon hurled him into a nearby building and it seemed as if he was pushing Azza into said building with gravity. Eventually the latter collapsed to one knee out of exhaustion. Azza having released from a huge shock of a spell that was unknown to him quickly used a sealing spell to prevent Dillon from moving as he walked up and prepared to deliver the final blow to the brother he had hated all his life. As Azza raised his axe, suddenly a massive beam of Holy aura sent him sliding back as he managed to block the attack with his axe. Dillon managed to turn around only to see his Queen Isaiah standing frim with a large group. It was his Peerage, as they slowly arrived to his aid. Azza gritted his teeth having realized his plans had been foiled and he was in danger of being taken captive. Chikara and Isaiah stood firm in front of their King while Asuna and Azrael began healing the wounded Dillon who slowly regained his strength and stamina. Azza tried to attack the group with his advanced magical spells but Isaiah and Chikara effortlessly overpowered the latter with their Longinus's and drove Azza into a nearby building. Ikki used his Sacred Gear Perfect Vision to find the latter while instructing Oringo on where to use his dark water technique to draw out the latter. Azza emerged from the building and summoned a massive thunderstorm with his axe and hurled a horde of lightning bolts at the group. Stella however was taught how to use her Sacred Gear Hellfire flames by Dillon and she expertly swatted away the lightning with a wave of her scorching flames. Azza had one last trick up his sleeve, he began to summon what he would later call the Nui beam which was a combination of all the elements (Fire, water, ice, earth, wind, lightning, light, darkness, and metal). Once he had stored up enough power he unleashed the massive beam upon the group but what he didn't realize was that Oringo had mastered Apophis's Dark Barrier technique which he instantly activated and it blocked Azza's powerful attack. Azza was then blasted with another wave of Holy aura that was followed up by a missle like projectile of tokui from Chikara that drove Azza into the ground. Azza got up and stated that destiny had other plans for he and his brother's battle and fate would not allow his capture. Isaiah having realized Azza meant he was planning an escape rushed forward and thrusted his spear. Unfortunately Azza was too quick and disappeared through a teleportation magic circle just as Isaiah reached him. Shortly thereafter Dillon thanked everyone for coming to his rescue as he slowly finished his recovery.

Meanwhile Kio managed to find Sairaorg as he landed only to find the latter in a battered and bruised state. He and Balberith had fought for 20 minutes straight throwing nothing but powerful punches that destroyed most of Sairaorg's Breakdown the Beast armor and Balberith had a few broken bones but both pushed forward. Kio flew overhead and crashed into the ground punching it so hard he left a small crater. Sairaorg and Balberith were pushed back by the shockwave but they managed to stay on their feet. Kio slowly rose up as he spoke to Sairaorg stating he was here to help to which the latter smiled stating it was about time. Balberith grew angry but Kio promised him that he would honor Sairaorg's promise of no harm coming to his family. Balberith accepted Kio's hospitality but he still refused to allow himself to be defeated and thus he enveloped himself in a powerful demonic aura that rivaled Sirzechs. The ground started to shake as Kio also enveloped his body in his own demonic aura and the two clashed fists. Buildings were shattered, glass broke and the ground cracked as Kio and Balberith both were pushed back by each other's immense power. However Balberith appeared to be physically stronger as Kio's jaw was cracked with just one punch. Sairaorg could not believe that Balberith had actually been holding back because he wanted to fight like Issei and thus he rejoined the battle more determined than ever. The trio exchanged blows while Dillon and his Peerage shortly arrived to witness the chaotic battle. They shortly surrounded Balberith who refused to surrender out of fear that his friends would get hurt. Asuna and Azrael began to heal Sairaorg while Verrine and Zeno pleaded with Balberith to surrender but he still refused. As Dillon and his Peerage prepared to move in Sairaorg shouted for them to stop. He said he was a man of his word and that Balberith had honorably defeated him. He ensured the latter that he would honor their agreement if Balberith promised to one day give him a rematch to which Balberith agreed as he was put into magical chains by Azrael and taken into custody by the CIA. A few moments later Rias Gremory and her Peerage along with the remaining members of DxD all converged on Vali and Issei's location as the battle between Hades was coming to a close.
