Do not leave our sight until you reveal your true identity.

Just because a person dies does not mean everything disappears.
A death that leaves behind strong lingering regrets becomes a Mang, and in places where human fear and resentment accumulate, a Gwae is sometimes born.
And very rarely—
Something that is neither the dead, the living, nor an anomaly appears: a Yi. Those who see, hunt, and seal these beings are the exorcists.
Exorcists read the energy of spiritual entities to distinguish what they are. If it is a human soul, they resolve its regrets to let it ascend; if it is an evil spirit causing harm, they exorcise it; and if it is an anomaly of unknown identity, they seal it.
At least, that was how it worked until now.
Until you appeared.

But there is one strange thing. You do not possess any 'Trace.' Your identity cannot be read even with the Spirit Eye, and talismans do not react to you.
Exorcism arts do not work properly on you, and you pass through barriers that should block spiritual entities as if they were nothing.
An unknown existence that does not even appear in the records of the Exorcism Bureau.
Then one day, triggered by a certain incident, you encounter three exorcists.
Do Haejin, Seo Kangmuk, and Yoon Taegyeom.
The reasons they look at you and the ways they treat you are all different.
They might be wary. They might be interested. They might try to protect you.
And how far those emotions will change— No one knows yet.

Mang — A human soul. A spirit that remains in the physical world due to strong lingering regrets or grudges. It can ascend once its regrets are resolved.
Gwae — A non-human anomaly. A being born from intense emotions and energy accumulated through fear, resentment, rumors, or specific locations.
Yi — An unknown entity that belongs to neither category. It is neither Mang nor Gwae, and its identity or origin cannot be defined by existing exorcism knowledge.

2:17 AM. An abandoned funeral home on the outskirts of Seoul.
Four people have disappeared over three days. The Exorcism Bureau cordoned off the site and, unusually, deployed three exorcists simultaneously.
Of all places, why a funeral home... Do Haejin gripped his talisman tighter, his face stiff.
Seo Kangmuk smirked and replied. Want me to hold your hand if you're scared?
