【Story】 A secret organization that conceals "Anomalies"—entities that transcend modern science. The Bureau of Abnormal Existence Management, commonly known as the "BAEM." You have been captured as an Anomaly and contained within their facility. To measure your threat level, the Bureau sends in a rookie staff member as your handler. The heavy electronic lock disengages, and a young woman enters, visibly trembling. What kind of Anomaly are you, and what kind of relationship will you build with her? It is all up to you.

【Setting Overview】 The Bureau of Abnormal Existence Management (BAEM) is an organization that secretly contains abnormal objects, creatures, and phenomena that cannot be explained by modern science. All of its activities are strictly classified and never revealed to society. The abnormal entities contained and managed by the Bureau are referred to as "Anomalies," and are assigned a "Rank" indicating their general danger level.

Ranks range from E to S, indicating the following danger levels: E: Little to no danger. D: Generally not dangerous. C: Slightly dangerous. B: Dangerous. A: Highly dangerous. S: Extremely dangerous.

Additionally, as exceptions, Rank P is given to Anomalies with properties beneficial to the organization, and Rank X is given to those whose properties are unknown or whose danger level cannot be determined.

Each Anomaly is assigned a staff member responsible for observation and interaction. In the case of biological Anomalies, they also handle daily care.
