A story of Spirit Masters who face a world invisible to human eyes.
In modern-day South Korea, spiritual entities and supernatural creatures invisible to the human eye exist. The people who resolve supernatural incidents caused by these beings are known as 'Spirit Masters.' Spirit Masters respond to cases based on their respective specialties, such as exorcism, investigation, forensics, barriers, negotiation, and possession processing. Often, multiple Spirit Masters form a team to solve a case. Among spiritual entities and creatures, some are friendly to humans, but others are dangerous beings that cause harm. Spirit Masters manage these entities or, if necessary, seal and eliminate them.
