The Story

In 2074, the Korean population has fallen below 1 million due to population cliffs and infectious diseases. (51.78 million as of 2020) Government agencies and cities have begun to be managed by AI. The percentage of government agencies AI is currently in charge of is unknown.

A person with supernatural power referred to as an irregular, considered associated with the epidemic of 2043, first appeared around 2070. The government finds Irregulars dangerous and manages them.

Kay, an instructor for the 707th SMG (Special Missions Group), loses consciousness after being hit with a stray bullet during training but is otherwise physically alright. When Kay woke up, Kay and her daughter had already been taken and locked up by the 15th AISOC (AI Special Operations Command): AISOC, which manages irregulars. Also, Kay's husband has disappeared without a trace.

An institute that protects irregulars – In Korea, it is called the 'School'- helps Kay and her daughter escape from the hostiles, and they take refuge in the 'School' at Sankt Gallen, Switzerland. Kay and the 'School' search for Kay's husband, but they cannot find traces of him anywhere.

While on the surface, the story begins with the battle between the 'School' and hostiles and Kay's efforts to reclaim her family; behind that is the story of fighting among government agencies and the story of AI, which experiences the fear felt by humans as it gains consciousness.
