Department of Countermeasures against Threats to Humanity

The silent guardians standing between humanity and the end of history.

The Department of Countermeasures against Threats to Humanity is a functional designation often associated with the operational mandate of the Chaldea Security Organization. While not always listed as a distinct proper noun in official materials compared to entities like the Clock Tower, this title encapsulates the specific mission undertaken by Chaldea's staff and Masters: to detect and neutralize anomalies that threaten the continuity of human history. It represents the proactive arm of humanity's preservation efforts, working directly with the Counter Force.

Lore & Background

The ideological core of these countermeasures prioritizes the preservation of the current human order over individual safety or alternative histories. This stance frequently puts them at odds with factions seeking Human Order Revision, such as the Ordeal Knights or specific Lostbelt Rulers. Despite the heavy burden of potentially sacrificing civilizations to save the main timeline, the personnel involved maintain a resolve rooted in hope for humanity's future potential.

In Their Own Story

The monitor screen flickered red, casting long shadows across the command deck. Goredolf stared at the data stream, his usual joviality replaced by steel. The anomaly wasn't just a Singularity; it was a tear in reality itself. Ritsuka stood ready, hand resting on the summoning interface. There were no backup plans left. This was the Department's final gambit: to walk into the fire of history and extinguish it before humanity burned.

Reader's Guide

The primary goal is to eliminate threats that could erase or rewrite human history. Leadership rests with Goredolf Musik as Director, with operational command often delegated to the Master (Ritsuka Fujimaru) during missions. Key members include Mash Kyrielight as Shielder and various summoned Servants acting as combat assets. Their role in the conflict is defensive yet proactive; they travel through time to correct deviations before they cascade into extinction events. Ideologically, they view magic not as a tool for personal gain but as a necessary resource for survival. They stand firmly against the use of Magic Circuits for domination, advocating instead for their application solely to secure humanity's future existence.
