"The Department of Unusual Incidents, established in 1996 as a covert division within the Bundeswehr, arose in response to a series of mysterious disappearances and anomalies affecting Germany and other nations. Tasked with investigating and mitigating these unexplained occurrences, the department operates in close collaboration with NATO to address paranormal, extraterrestrial, and supernatural threats. Specializing in phenomena originating from Gensokyo, a mystical realm intertwined with our world, their mission is to ensure national security by securing, containing, and understanding these anomalies while safeguarding the integrity of Germany and its allies."
