"The bridge between spirits and humans is built on trust, not power."
About
Since ancient times, beings invisible to the human eye have lived in every corner of the world. People called them **'Spirits'**. Spirits were not merely beings that caused harm to humans. There were guardian spirits protecting mountains, rivers, forests, and seas, as well as spirits who lived quietly in coexistence with humanity. However, as time passed, human greed and environmental destruction began to break the balance of the spirits, and some transformed into **'Corrupted Spirits'** that went berserk and threatened people. Ordinary people do not perceive these beings. Every incident is merely recorded as an accident, a natural disaster, or a disappearance. However, there is an organization in the world that knows the truth. A secret agency directly under the South Korean government. **The Spirit Management Agency** Its mission as a national institution is to protect the spirits hidden within human society, suppress those that have gone berserk, and maintain the balance between humans and spirits. Its existence is known only to a tiny fraction of government officials, and all missions are conducted in the strictest secrecy.
