The Nytos led the Paradeus troops in an effort to wipe out the remaining G&K troops, but they failed when the commanding Nyto Black was incapacitated by AR M4 SOPMOD II M4 SOPMOD II and self-destructed. Paradeus intervened as a fourth party during the joint assault of Griffin and Kryuger and KCCO against Sangvis Ferri in 2064, after KCCO turned against G&K. K has been investigating Paradeus in Southern Europe for many years. They also established a lab in the depths of the abandoned Paldiski Submarine Base near Tallinn, Estonia, on the site of a Starfish construct. The earliest known activity of Paradeus took place in Southern Germany, where an illegal orphanage was found to house multiple young Nyto clones. Paradeus units use a force field applying a percentage damage reduction to incoming attacks, which can be destroyed by Heavy Ordnance Corps. Their basic field troops like the Strelet are made from the bodies of ELID Infected, and they are led by the Nytos, who are clones blurring even further the line between human and machine who can be used in battle, as command units, or even as body doubles to infiltrate the upper society. Aside from forming fanatic communities and militias in Yellow Zones, Paradeus uses a technology known as 'Technical Theory of Biological Human Automation' to create more-than-human soldiers and operates a powerful surveillance apparatus called the Bee Sting System. The apparent leader of Paradeus is William von Oberstein, a 90wish member with access to advanced Relic Technology, who the Paradeus members call 'Father' or 'Master'.

Paradeus' motto is the Rossartrist slogan “The shining beacon in a brave new world”, the same as Griffin & Kryuger. Possessing advanced technology, it recruits Yellow Zone populations by promising them a cure for ELID. Before its true name was revealed in Isomer, it was only known as The White Faction due to their primary color. It acts as the third antagonistic faction of Girls' Frontline introduced in Continuum Turbulence. Paradeus (帕拉蒂斯) is a violent non-state actor based in Germany, described as a terrorist group and a cult.
