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).

Summary
The Qlippoth was first known when Drakon reveals himself to be a part of the people experimenting on the Twilight Graal and 2 fragments of the original Holy Grail. He eventually transformed the Vampyres of the Tepes, Carmilla and Dracula Factions into Evil Dragons to serve as his army. Drakon later leads his army and successfully steals Agreas from the Underworld, using Agreas as his base and a place to keep 666.

Following the attack on Heaven (again led by Drakon due to mischief), Drakon began to hasten his plans for reviving 666. After being beaten by Arthur and Vali and killed by Aoqin, Drakon uses his own soul to revive the 666 while Cythraul, Apophis and Aži Dahāka betrayed Drakon, taking over his place as the leader of Qlippoth.

Under the new leadership of the son of Asmodeus and the two Evil Dragons, Qlippoth began to attack various places and myths causing havoc even in the Human world. Qlippoth, however, eventually met its end as an organization after Cythraul, Apophis, and Aži Dahāka were defeated in battle while 666 was sealed in the Isolation Barrier Field and Ladon was sealed in Limbo.

Purpose
The group functions as an terrorist cell with the purpose of defeating Scarlet Grand which protects the Dimensional Gap, so that they can invade the other world of ExExE and cause destruction there with the army of Evil Dragons. To combat Scarlet Grand, it set about reviving the legendary Imperial Beast, 666 (Trihexa).
