Hexennacht, also known as Witches Night, is a group of Stray Magicians, who cooperated with Qlippoth.
In Volume 16, during the Vampire Civil War, it is revealed that Hexennacht had begun cooperating with the Khaos Brigade, as Walburga and her subordinate Magicians engaged the Vali Team in battle, with Arthur Pendragon, Bikou and Fenrir staying behind to fight them so that Vali Lucifer could proceed onwards to confront his grandfather; Rizevim Livan Lucifer, who was the new leader of the Khaos Brigade.
In Volume 17, Walburga lead the assault on Auros Academy while the members of Hexennacht along with other Nilrem Magicians infiltrated the Magicians' Assembly, secretly altering the teleportation spell that was meant to teleport civilians to safety into a spell that teleported the sky city of Agreas, allowing Qlippoth to steal and seize it. The Hexennacht Magicians fought against the members of the Magicians Assembly but were defeated as all of the Hexennacht Magicians that infiltrated the assembly were killed by the self destruct spell that Euclid Lucifuge implanted into some of the Nilrem Magicians, reducing Hexennacht significantly.
In Volume 19, during the Exorcist Rebellion, Walburga was defeated by Team DxD and imprisoned by the Three Factions. With its leader imprisoned and a significant loss of manpower, the organization was forced to dissolve.
