## Summary

The second battle between Team DxD and Alliance of Hell, as Erebus seeks to get revenge on Team DxD, for defeating his sister and King Enma, for rejecting the offer to join the Alliance of Hell, as Team DxD races to stop Erebus' before he plunges Japan into chaos.

## Prelude

During the Occult Research Club's trip to Kyoto to perform a Oppai Dragon live event, along with the Slash/Dog Team and Hero Faction serving as security, the gathered members of Team DxD received a report from Sun Wukong about weird magic spells being put on the temples in Kyoto and its surroundings, on the temples that worship King Enma, as by investigating them confirmed them to be ancient Olympus magic, with Team DxD suspecting the primordial Gods' that were affiliated with Hades' were involved in their placement, as the leader of the Kyoto Youkai Faction; Yasaka raised the security at Urakyoto and the Slash/Dog Team as well as the Hero Faction began to patrol Kyoto in order to secure it and figure out the true culprit.

While the members of the Occult Research Club, Yasaka and Kunou were walking through Kyoto, they were attacked by two of the Alliance of Hell's top Devils; Gressil and Sonneillon. Yasaka created a artificial space to prevent their battle from affecting Kyoto, as the Occult Research Club members were slowly getting overwhelmed due to not being able to fight at full power in order to not destroy the artificial space, as Gressil and  Sonneillon attempted to remove their limiters and defeat the group, regardless of the damage they may cause to Kyoto. The Hero Faction arrived to aid the members of the Occult Research Club, as the two devils retreated by being teleported away.

Regrouping at Yasaka's mansion, the members of Team DxD began to coordinate with the Kyoto Youkai faction to respond to Erebus' actions, as the assembled teams would be divided into several teams, each with a different task.

The Hero Faction's Georg, the possessor of the Longinus; Dimension Lost, would create a pseudo-space in another dimension and control it, deploying a magic circle to check enemies’ current situation. Georg’s role was to keep an eye on the pseudo-space, as well as locking the enemies so they didn’t escape. Elmenhilde Karnstein would be left in Urakyoto in order to become Georg’s support.

The offence team would basically be the Gremory peerage, Slash Dog Team, the Hero Faction and the Youkai from Urakyoto lead by Yasaka, who would go to Erebus’ main force in the pseudo-space and fight them there. Lint Sellzen joined the Hero Faction's side due to her own request, wanting to fight with her brother's Siegfried's comrades.

The support and defence team would be the Journey to the West team, the current second-year students of Kuoh Academy and their teachers (Koneko Toujou, Ravel Phenex, Gasper Vladi, Ingvild Leviathan, Ouryuu Nakiri, Millarca Vordenburg, Ruruko Nimura, Rossweisse and Roygun Belphegor) as well as members of the Five Principal Clans, as they would respond to Erebus’ other forces and try to defend both Kyoto and Urakyoto to the very last.

As Georg was checking the enemies lcoation, he was noticed by Erebus, as Georg activated his Balance Breaker and started to create the artificial space, as well as beginning to transfer the enemies to it, though Erebus used his magic to temporarily resist as Georg tried to teleport the offense team as close to the enemies as possible as the offense team was teleported to the artificial space.

## History

The defensive group consisting of the current second-year students of Kuoh Academy and their teachers (Koneko Toujou, Ravel Phenex, Gasper Vladi, Ingvild Leviathan, Ouryuu Nakiri, Millarca Vordenburg, Ruruko Nimura, Rossweisse and Roygun Belphegor) as well as members of the Five Principal Clans gathered in the uninhabited forest in the vicinity of Iwashimizu Shrine of the God of War, which was placed in the ‘unlucky quarter (Southwest)’ of Kyoto. Suzaku Himejima and the Magicians from the Five Principal Clans gathered in Mt. Hiei’s Enryakuji temple while the ‘Evil Southwest’ was protected by the Kuoh Academy’s group. As the Artificial Devils arrived, the Kuoh Academy group engaged them in battle, with Ingvild forming water dragons with her demonic power to attack the artificial devils while Ouryuu created earth mounds that floated and completely swallowed the artificial Devils. Koneko incinerated the artificial devils with her Kasha, while Rossweisse attacked with her magic and Roygun with her *Crack* ability. Millarca punched the artificial Devils and Gasper used his Balor form to pummel them, while Nimura began to kick them away with her Artificial Sacred Gear, as the the Kuoh Academy group protected Kyoto long enough for the main force to defeat Erebus.

Meanwhile, Cao Cao’s group, the Hero Faction, was the first to come in contact with the enemy’s main force after being transported to the pseudo-space that resembled Urakyoto. Near the small river in the east, both the Hero Faction and Erebus’ group were glaring at each other from the opposite banks of the river as the two engaged each other in combat, with the executives of the Hero Faction decimating the artificial Devils with their Balance Breaker abilities, while Cao Cao faced Sonneillon in battle. As Sonneillon attempted to use his demonic powers to crush Cao Cao, Cao Cao continuosly evaded his gravity attacks as he used his Balance Breaker's abilities to generate duplicates to disorient Sonneillon and cut off his arm, leaving him defeated. Cao Cao asked Sonneillon to surrender as the Cao Cao's higher-ups wanted to capture Sonneillon alive. Sonneillon resisted as he created a Demonic Power Bomb using his powers and the corpses of the artificial devils, which he attempted to send to the Urakyoto, but the bomb was destroyed by Heracles. Cao Cao then kills Sonneillon, as Sonneillon was vaporized due to the Holy Spear's holy aura.

At the same time, the Slash/Dog Team engaged in battle against the group of Artificial Devils — Erebus’ group in the mountain that was located at the west side of the pseudo-barrier space that resembled Urakyoto, with Tobio Ikuse taking on their leader, Gressil. Deciding to end the fight quickly, Tobio transformed into his Abyss Balance Breaker, as he fought against Gressil in a vicious duel. Gressil grew overconfident due to believing that he had already adapted to Tobio's aura blades as he casually tried to withstand Tobio's blade, only for it to damage him, as Tobio revealed that he altered the wavelength of the aura, therefore bypassing Gressil's Resistance as Tobio killed him while Lavinia Reni froze the rest of the artificial devils, defeating them.

Meanwhile, a group of Devils infiltrated the Youkai forest in the vicinity of Kyoto as they began to cause chaos though were defeated by Balberith who was visiting the village to buy a Oppai Dragon figure and grew enraged by the artificial devils actions. The Journey to the West team came to the village due to recieving infomation that the village had been attacked. While originally suspicious of Balberith and Zeno, the Journey to the West team let them leave after seeing Balberith give the figure he bought to a Youkai child who had lost his in the attack.

As the main force that consisted of the Gremory peerage, Hyoudou peerage, and the Youkai  warriors who were confident in their strength lead by Yasaka, teleported to the ancient ritual spot located in the northern part of pseudo Urakyoto, they engaged the artificial devils as Rias told Issei to deal with Erebus while the rest of the group continues to fight against the artificial devils. Issei flew towards the altar, he transformed inot his Diabolos Dragon form as Erebus revealed himself. Issei offered Erebus a chance to surrender but Erebus refused as he wanted to defeat Issei to avenge his sister's defeat. Issei quickly defeat Erebus by using Infinity Blaster, though before passing out, Erebus was able to cast a dark sealing spell on Issei.

As Issei dragged the defeated Erebus and regrouped with his comrades, they were enveloped by a large darkness that was restraining them with Tartarus revealing himself and stating that he intends to seal all of the Longinus wielders present in the Abyss to prevent the Longinus from becoming a threat as killing the current wielders would only make the Longinus manifest in different wielders. Issei tried to resist and manifest Ddraig, but was forced to the ground by Tartarus manipulating gravity as Issei was incapable of manifesting Ddraig due to Erebus' sealing technique. Ophis and Lilith teleported to their location as they revealed that they brought Ryuuteimaru with them. Ophis and Lilith freed Issei from the darkness restraining him as they threw him towards Ryuuteimaru so Issei could combine with him. Issei combined with Ryuuteimaru, as Ryuuteimaru manifested a new form: **Apocalypse AnswerArms**. Piloting Ryuuteimaru, Issei was able to overwhelm Tartarus. During their confrontation, Ddraig was able to manifest due to Ryuuteimaru's influence as he and Issei teamed up to fight against Tartarus, defeating him by combining their finishing attacks.

## Conclusion

After the attack on Kyoto, Erebus and Tartarus were captured by Team DxD and sent to be sealed away.

Due to the Erebus' attack on Kyoto, the higher-ups of the Three Factions and the VIP's of the other mythologies had ordered Team DxD to destroy Hades and his patrons as the attack was considered a proclamation of war by the Alliance of Hell against all mythologies.

After losing two more Gods as part of the Alliance of Hell, as well as a a vast amount of artificial Devils, Hades prepared himself for the final confrontation with Team DxD and the rest of the mythologies.

Receiving a request from the Pendragon family, Team DxD was asked to assist in the matter involving one of the newly manifested Longinus; **Alphecca Tyrant**, as well as the news of the Two Heavenly Dragons being spotted in England. Determining that the two Dragons are impostors, Team DxD prepared to visit England to deal with the matter, as the Gremory peerage, Hyoudou peerage, Bael peerage and Vali team prepared to go to England as the main force.

Due to Ryuuteimaru's transformation being unstable and consuming a lot of energy, he was sent to the Grigori to be studied further as Azazel proposed a method for controlling it and managing the stamina problem; by borrowing the power of Eros, the Greek God of Love and Sex; called *Eros Engine*. It is also discussed that Ryuuteimaru's growth was the result of him preparing for the [UL] invasion due to retaining his memory of the time travelling invasion of the [UL] prior.

As a result of Team DxD's achievements, talks about promotions for most of it's members were taking place as, the higher ups wanted to promote them due to their accomplishments.
