The **Devil Civil War** describes the conflict between the descendants of the Satan Clans, that wanted to claim the thrones of the Original Satans and declare war on Heaven and the Fallen Angels, thus restarting the Great War and the Anti-Satan Faction, that was opposed to them as they believed that another war could lead the Devil race into extinction.

## Summary

The Devil Civil War is a conflict that started around the time when Sirzechs Gremory was 60 years old, about 500 years before Issei Hyoudou becomes a Devil, and changed the way Devils were ruled. It started when the 72 Pillar Houses, under the lead of the Houses Bael and Agares, rallied followers to counter the possible restarting of the Great War from the Satan descendants and ended when Bidleid Beelzebub, Tsufaame Leviathan and Damaidosu Asmodeus were killed and their troops had been defeated. It also marked the rise of the new Four Great Satans out of the 72 Pillar Houses Sitri, Astaroth, Glasya-Labolas and Gremory.

### Prelude to the War

After the Death of the four Original Satans her direct children, Rizevim Lucifer, Bidleid Beelzebub, Tsufaame Leviathan and Damaidosu Asmodeus were to be expected to take up the Satan thrones of their parents. Rizevim Lucifer, however did not show any ambitions to take over the position of Satan Lucifer in the Underworld, so the governance of the Underworld fell to the other three Satan descendants.

The Satan Clans based their power over the Underworld not just because of their heritage but also that their members were much more powerful than a normal High-Class Devil of the 72 Pillars. Young Devil Gatherings were held regularly within the capital of Lucifaad, but not to further the relations between the heirs of the 72 Pillar Houses and the Satan clans but to intimidate the heirs and to show that the Satan descendants were superior to them. The Satan clans counted only themselves and the members of the Six Houses of Lucifer as true Devils and the remaining people of the Devil Society, inclusive the 72 Pillar Houses, as disposable beings that they are not counted as true Devils (this could be because they were created by Lucifer for his war against Heaven).

The escalating tensions laid the base for the Civil War. When the Satan-Descendants Bidleid Beelzebub, Tsufaame Leviathan and Damaidosu Asmodeus made it known that they would claim their parents throne as Satans and restart the Great War, the 72 Pillar Houses; Bael and Agares started to build a coalition to counter it. Zekram Bael did his best to bring the Houses Sitri, Astaroth, Glasya-Labolas and Gremory to their side because of the immense power that the clan heirs possessed and was said to be equal if not superior to the Original Satans.

As the 72 Pillars Pillar Houses were discussing their further plans and actions, a young Beelzebub-descendant gave the order to massacre all members of the resistance faction that are in the city of Lucifaad, without care for civilians or casualties among them. This was the decisive spark that started the already looming Civil War finally. The massacre in Lucifaad was also the event that brought Sirzechs Gremory to the decision to fight against the Satan clans, his friends Ajuka Astaroth, Serafall Sitri and Falbium Glasya-Labolas following him.

### The Civil War

At the beginning of the Civil War, the battles between the Satan Faction and the Rebel troops were one-sided in favor to the Satan Army troops. This changed as Serafall Sitri, Falbium Glasya-Labolas, Ajuka Astaroth and Sirzechs Gremory became involved in the battle and took command of the Anti Satan coalition armies. When the four started to take command of the troops, the tide of the war began to shift.

The four battles that determined the outcome of the civil war were the "*Battle of Gusion Castle Town*", the "*Battle of Valefor-Territory*", the "*Surprise Attack at Eligos*" and the "*Final Decisive Battle of Lucifaad*".

#### Battle of Gusion Castle Town

The first decisive major battle that took place around six Month after the Start of the Civil War at the Territory of the extinct House Gusion, the Gusion Castle Town. The city has been long being deserted, and was only in ruins, a territory for wild beasts at the time of the battle. The Battle at the Gusion domain had Tsufaame Leviathan as the commander of the Satan Army on one side and Ajuka Astaroth as the commander of the Anti-Satan troops on the other side.

Ajuka's troops had Initiated the battle with the Leviathan Troops that has took formation around the center of the Gusion domain. After thy took out all of Tsufaame's generals, Tsufaame herself decided to enter the battle as she used her abilities to issue devastating attacks against the Rebel troops pushing them back.

This forced Ajuka Astaroth to fight her. But despite Tsufaame Leviathans best efforts, unleashing powerful attacks by using her clan trait, strong enough to easily defeat Ultimate-Class Devils or drown entire cities, Ajuka was able to counter all of her attacks with his Kankara Formula, leaving the daughter of Leviathan gasping for air. Even fully transformed into a giant serpent-like Dragon, that was the true nature of Leviathan, firing gigantic dark blue aura beams multiple times at him the Astaroth Devil simply deflected them into random directions, creating giant Explosions. Each of these Explosions by himself strong enough to destroy an entire Army.

As she was exhausted and injured, Ajuka Astaroth offered her a chance to surrender, but she refused with the words "*I, daughter of Leviathan, shall never surrender to the likes of you! You scum!*", putting her class, reputation and honor over her own life. With the words: "*I´m sorry. But the Underworld doesn´t need you*.", Ajuka killed her thus ending the battle at Gusion territory in the Anti-Satan Faction's favor.

#### Battle of Valefor-Territory

While Ajuka Astaroth's troops moved on to Lucifaad after defeating Tsufaame Leviathan, another part of the anti-Satan army led by Serafall Sitri was involved in a battle within the abandoned Valefor territory.

Here Serafall Sitri and her army nearly succeeded in cornering Damaidosu Zereikel Asmodeus and his army. However, Damaidosu's army was reinforced by the appearance of Troops from the Six Houses of Lucifer, which were lead by Grayfia Lucifuge. Grayfia Lucifuge, who was deployed to deal with Serafall, and her former friend started to fight each other so furiously that all that were witnesses of the fight were wondering whether the two were still even Devils. But neither of the two could gain the advantage and their fight continued for 10 days before Sirzechs and his army appeared. This forced Grayfia's and Damaidosu's army to retreat.

As Serafall chased Grayfia and her army, continuing their duel, Sirzechs used that as a opportunity to hunt down Damaidosu Asmodeus. As Sirzechs nearly had reached Damaidosu's base, he was attacked by Euclid Lucifuge, Grayfia's younger brother, though Sirzechs easily defeated him without injuring him too much.

Sirzechs was preparing to transport Euclid back to a safe zone as the young Beelzebub youth, that Sirzechs had humiliated when he was a teenager, appeared.
The young Beelzebub-Descendant, using a part of the Malebranche Scullmigliones power, transformed into a giant Fly Chimera and began to release a deadly poison, targeting members of both sides of the conflict. Taking Euclid to the Lucifuge base, Sirzechs convinced Lord Lucifuge to withdraw his troops as Sirzechs planned to deal with the Fly Chimera himself. The Fly Chimera advanced to the lake at west side of the Valefor domain, moving into direction of populated areas, as Sirzechs moved to intercept it. After trying and failing to convince the youth Beelzebub to surrender, Sirzechs assumed his True Form and used Ruin the Extinct to destroy the Fly Chimera from the inside together with the poison, leaving no trace of them and ending the battle at the Valefor territory.

After the Fly Chimera was destroyed, the battle between the armies continued, ending with the defeat of Damaidosu Zereikel Asmodeus by Sirzechs Gremory and Serafall Sitri, as the two ace of the Anti Satan faction killed him. The troops of the Lucifuge Clan surrendered and Lord Lucifuge, succumbing to the effects of the poison from the Fly Chimera, gave Sirzechs his last wish to dismantle his House so it would not fall into Euclid's hands and to take care of Grayfia.

With the defeat of the Leviathan army, the Asmodeus army and the Lucifuge troops, the Satan Faction lost the power to prevent the Invasion of the Capital Lucifaad.

#### Surprise Attack at Eligos

Around at the same time as the Battle on the Valefor Territory was going into it´s decisive phase, the troops of two of the Houses of Lucifer attacked the Resistance headquarters that was in the old Eligos Territory. These 200 elite troops of the Satan Army were lead by Lords of House Agaliarept and House Fleurety, who had used secret paths to be able to approach the defense lines unnoticed.

As the elite troops attacked, firing continuous blasts of demonic power in hopes of trying to kill the leadership of the Anti-Satan Faction, all of their attacks were blocked by Falbium Glasya-Labolas with his unique ability; Absolute Defense. As he absorbed all of their attacks, Falbium used the absorbed attacks to generate a counter attack, wiping out nearly all of the opposing force, with the exception of the Heads of the House Agaliarept and House Fleurety and a few other soldiers, as they were taken into custody.

#### Decisive Battle of Lucifaad

As Sirzechs, Serafall and Ajuka regrouped together, the three lead the attack at the capital of Lucifaad as the forces of the Beelzebub army and the remaining members of the Six Houses of Lucifer couldn't withstand their power. The trio entered the capital, as they began seizing the main facilities of the capital, eventually reaching Bidleid Bashalun Beelzebub's palace.

Bidleid tried to fight Sirzechs, but Sirzechs used his True Form to overwhelm Bidleid, eliminating one of Bidleid's arms, one of his legs, half of his wings and left him bleeding heavily. Sirzech offered Bidleid a chance to surrender but Bidleid refused, with Bidleid telling Sirzechs; "*The blood and wrath of the Satans shall always stand against you*", as Sirzechs killed him, thus ending the Civil War.

### Conclusion of the War

After the war concluded and the Surviving members of the original Four Great Satans clans were driven to the outskirts to the Underworld, Zekram Bael asked the aces of the Anti Satan Faction (Sirzechs Gremory, Serafall Sitri, Ajuka Astaroth and Falbium Glasya-Labolas) to become new Four Great Satans.

Due to not having any place to go to after the destruction of her House, Grayfia Lucifuge was taken into the Gremory domain by Zeoticus Gremory's request. Sirzechs Gremory later proposed to Grayfia Lucifuge, which she accepted. When Sirzechs later became the Satan Lucifer, Grayfia became his Queen, true to the last wish of her deceased father as his lasts words were that "*Lucifuge must always be with Lucifer*".

Without the Satan Clans, the newly formed Great King Faction, under the leadership of the Houses Bael, was able to expand it's influence as the commanding authority, comparable or even a bit superior to the New Satans, as the two had disputes over the future of the Underworld. This contrasted to the previous absolute rule of the original Satans would result in a political tug of war that would remain ongoing for several centuries.

Nearly all of the Six Houses of Lucifer were destroyed in the conflict. Zaorama Nebiros took the resealed Malebranche into a secret Place in the Underworld to research them and the phenomenon of the Transcendental Devils.
Euclid Lucifuge swore revenge against Sirzechs Gremory for destroying the Satans, his House and "stealing" his sister. A few centuries later, he and his own group; Nilrem would join forces with Rizevim Lucifer's organisation; Qlippoth.

The surviving members of the Satan clans that were driven into the outskirts of the Underworld became later the Old Satan Faction.
