Oberhaupt - Monsters Hierarchy
In 2029, a virus designated Tokbog-29 spread globally, originating from Russia and within two years, the virus claimed over 800,000 lives. By 2037, the death toll had reached 760,000,000.
In 2038, in Japan, a Tokbog patient transformed into a powerful monstrosity that nearly wiped out an entire hospital. It was eliminated by the Japan Self-Defense Forces’ special operations units after seventy-two hours of sustained engagement.
The creature, codename Chimera, was the first of many entities to emerge from infected patients. What initially appeared to be an isolated incident soon escalated into a full-scale invasion of aberrant, demonic creatures referred to as Ijo (Japanese for “Anomaly”) or Zmij (Russian for “Dragon”).
The year 2038 marked the beginning of the Anomalous War, which lasted until 2047. The conflict was fought by the United Nations Armament and Defense Forces (UNADF), particularly through its specialized branch, the Ijo Counterattack Protocol (ICP), known in Russia and Europe as the Zmij Extermination Division (ZED).
In 2047, with the assistance of the technological corporations Bryte and Rodak, the Class-Y Human Containment Space Station, also known as Remnant, was completed. Launched from the Moon and positioned beyond lunar orbit, it carried more than 3.5 billion people — the last surviving civilian population of humanity.
Only the military remained on Earth.
In 2049, military experiments subjected human test subjects to a modified and controlled substance found inside the Tokbog-29 bacteria. Unlike the virus, this substance did not kill the host. Instead, it generated a powerful electrochemical discharge, granting subjects behavioral traits and combat capabilities approximately fifty percent comparable to an Ijo.
The substance was designated Tokbog-29β, also known as Nectar. Under extreme psychological stress — fear, rage, or trauma — it triggered the development of the Hirngeist, a system that altered both the psychological and physical state of the host.
Soldiers implanted with Nectar can activate it for a maximum duration of one minute — just enough to finish an engagement.
Afterward, the Kariudo-Type Mark III combat suits automatically administer an Inhibitor, a temporary counteragent that suppresses both body and mind, placing the host into a medically induced coma for approximately three days. Following recovery and rehabilitation, the soldier is cleared for combat once more.
Each military base fields three squads of four soldiers. Together, these squads form an Oberhaupt, the command unit responsible for their coordination, composed of personnel ranging from seventeen to forty years of age.
If a soldier exceeds the imposed activation limit, they enter overload — a state known as Hirn Brecher, or the Harbinger Event — which in most cases results in death.
The story takes place in 2054. The protagonists have been members of an Oberhaupt unit for at least two years.
