Chaos Insurgency

The Chaos Insurgency, also known as the Agency of Disaster, was a terrorist organization in Vampyres, Knights and Boobs. The Chaos Insurgency consisted of multiple races: Vampyres, Devils, Fallen Angels, Humans (who are descendants of legendary/mythological heroes and former or exiled members of the Hero Clan), and a few Seraphs.

History
Originally founded with the purpose to create an opposing force to the growing alliances of mythologies, the Chaos Insurgency was built as a cooperation between the Greek Goddess Phobetor, the Fallen Angel Kokabiel and the Wizards of Oz. At some point, it was handed to Sataniel, the only son of the previous Vampyre Lord Marius, and Mina's and Hinami's older half-brother, and Wagyl, the Dragon God of the Dreamtime.

Summary
The Chaos Insurgency first appeared in Volume 3, introducing themselves to the world and attacking the leaders of the Five Factions and Mina Karnstein. Shortly after that, the Chaos Insurgency began to start many terrorist attacks, such as assassinating several VIPs during Arthur's Rating Game against Leohart, kidnapping the Youkai leader, Yasaka and Tepes Factions leader, Valerie Tepes, and committing many other atrocious acts.

In Volume 11, the Hero Faction betrayed their leaders Sataniel and Wagyl after Cao Cao, the leader of the Hero Faction, sided with Morpheus, the Greek God of Dreams, and used Samael to steal most of his powers under the intention of creating another Wagyl, and before also stole a bit of Maria Karnstein, Arthur's and Le Fay's mother and the Ourorboros Dragon Goddess Ophis' powers. This has resulted in Sataniel and Wagyl both remaining in presumed powerless states. However, Wagyl released her powers in the form of snakes before Cao Cao came to steal her powers. As such, Wagyl did not lose most of his powers.

As of Volume 13, the Chaos Insurgency's three largest factions were greatly weakened by the loss of their leaders and various members. This led Azazel into speculating that the other factions of the Chaos Insurgency that had been lurking in the shadows, would soon arise and take action. In Volume 14, Azazel revealed that there was someone who was trying to unify the remnants of the Old Maou Faction, New Olympus Faction, Hero Faction, Sacred Beast Faction, Greta Faction, and Magician Faction.

In Volume 17, it is revealed that the Son of the Original Leviathan, Drakon La Leviathan, became the new leader of the Chaos Insurgency. He planned to reach Limbo and other worlds by having Apocalyptic Civil Beast, 666 (Trihexa) fight the Apocalypse Inferno Dragon, Scarlet Grand. A new faction called Qlippoth was created and this faction planned to use the Twilight Graal and 2 of the 5 fragments of the original Holy Grail to revive the Evil Dragons who are feared by every mythology and religion.

In Volume 20, 666 was successfully awakened when Drakon after death, used his soul to awaken the beast and it, along with the Evil Dragons Apophis and Ladon and Cythraul Sohn Asmodeus the son of the Original Asmodeus, who had betrayed Drakon taking control of Qlippoth, set out to attack the mythologies. In Volume 21, the trio of 666, the two Evil Dragon leaders and the son of Asmodeus caused great destruction, almost completely decimating Heaven, Grigori, Asgard, and Midgard, killing many Gods in the process and soon after, began attacking Europe, Africa and Japan in the Human World. The Chaos Insurgency officially came to an end when Qlippoth was finally defeated in the Evil Dragon Campaign.

Qlippoth
Qlippoth (クリフォト Kurifoto) was an organization that was under Drakon La Leviathan, which had the main purpose to invade other world using the Evil Dragons. For that goal, they seeked to defeat Scarlet Grand which protects the Dimensional Gap by reviving the legendary beast, 666 (Trihexa).

Hidden Chaos Insurgency
The Chaos Insurgency and its successor group Qlippoth couldn't function normally due to their valuable charismatic figures — Cythraul Sohn Asmodeus, Zakhen Mammon, Cao Cao, Edward Teach, Drakon La Leviathan and Rizevim Livan Lucifer being defeated by Eden. However, there are still a considerable amount of people that took over organization's ideology or devoted themselves to it, and even now their numbers were increasing little by little. Hidden Chaos Insurgency spies exist in every mythology and nearly every place affiliated with Eden, including Tokyo, the Hero Village and even the Karnstein, Tepes, Gremory and Sitri households. Members of the Hidden Chaos Insurgency were leaking information on Eden to the Alliance of Nightmares, including information on the barrier that surrounds Tokyo, which all factions cooperated to create, and the location of the Hero Village.

Apollo Team
The Apollo Team (アポロチーム, Aporo Chīmu) was a special team of the Chaos Insurgency led by Vali Apollyon, the descendant of Apollo and the keeper of Albion, the White Dragon Emperor and the arch-rival of Ddraig, the Red Dragon Emperor. The Apollo Team was not connected to any of the factions of Devil's Hand and acted independently.
