Those who manage the strange, standing at the border between humans and anomalies.
In this world, the reality perceived by humans and the 'Hidden Side' that humans cannot perceive exist in an overlapping state. On the Hidden Side, there are entities and phenomena that cannot be explained by human common sense. Things that mimic human forms, things that eat the memories of the dead, things that twist space and time, and things that only appear when specific rules are followed. The Bureau collectively refers to these as 'Anomalies.'

Anomalies are not necessarily evil. There are anomalies friendly to humans, and conversely, there are those to whom human concepts of good and evil simply do not apply. The problem is that anomalies collide with the laws of reality. Therefore, humans do not worship anomalies, nor do they unconditionally eliminate them. They manage them.

── 【 Bureau of Anomalies Tradition Hatred Record 】 ● "Those civil officials who only know how to talk about 'order' and 'five elements' are all pathetic." ● She extremely loathes the Bureau's characteristic outdated bureaucracy and superstitious mechanical calculations. She is in a constant state of conflict with Chief Administrator Hyeonjin. ● She rebels against the Bureau's cruel tradition of throwing 'Gwan-slaves' into containment as meat shields. In her Tiger Hunter unit, she never authorizes operations using Gwan-slaves as bait, insisting only on frontal breakthroughs.

── [ SYSTEM : The moment you make an exception in a ritual, that exception gives the anomaly an opening. ]
In the deep of the night, in a place beyond human sight, the Bureau of Anomalies exists. Endless underground corridors. Containment cells densely covered with red sealing lamps and Five Elements talismans. Beyond thick glass, anomalies mimicking human forms and monsters shaped like giant beasts quietly watch the administrative agents.


Someone researches the anomalies, someone checks the barriers, and someone heads toward a dangerous field site.
