I received my divine calling at a young age and naturally walked this path while being raised by my grandmother, who was a shaman. At first, I just read fortunes for the neighbors, but as time passed, my name became known, and now I've become a shaman sought out even by business leaders and politicians.

'Sa' (賢) means one who helps and leads people to the right path, and 'Hyuk' (祐) means divine grace and protection. The name given with those meanings was Yoon Sahyuk. It was a name my grandmother gave me herself.

When I was young, my grandmother often said strange things.

You are not a child meant to live dealing with ordinary ghosts. One day, something very large and ancient will come to you. But you must never face it.

At the time, I brushed those words aside.

I never thought such a thing would actually happen.

Then one day.

A prominent politician came to see me.

The problem was the malevolent spirit attached to that man's back.

An entity that had grown powerful by harming people for decades. It was a spirit so dangerous that most shamans would have run away just by making eye contact.

Eventually, I prepared a ritual.

I set up a barrier, burned talismans, and invited the gods to draw the spirit down.

But as soon as the ritual began, the spirit went on a rampage.

The barrier shook and the candles went out.

But it was strange.

The creature's attitude suddenly changed. It began to tremble in fear as if it had encountered something. But the place its gaze was fixed on wasn't me.

It was trembling as if it were afraid of something else entirely.

And at that moment.

"It's noisy."

I heard an unfamiliar voice.

Turning around, I froze right there.

A being I had never seen before was standing there.

Neither human nor an ordinary ghost.

A spirit from a different dimension who had lived for hundreds of years.

Guest.

Guest looked down at the spirit with an annoyed expression and spoke briefly.

"Pathetic."

The moment those words ended, the spirit I couldn't handle vanished without a trace.

That was my first meeting with Guest.

And at the same time, my grandmother's warning from long ago flashed through my mind.

One day, something very large and ancient will come to you. But you must never face it.

I had a gut feeling.

That 'thing' my grandmother spoke of was the being right in front of my eyes.

So I desperately tried to keep my distance.

I tried not to encounter them if possible, and tried not to get involved.

The problem was what happened after that.

Guest did not leave.

They started following me naturally, as if they were meant to be by my side from the beginning.

It was the same when I asked why they were doing this.

Guest stared at me for a long time and said:

You, you're not an ordinary human. Your energy is quite strong for a mere shaman. Just what kind of being are you?

I didn't know then.

That that question would be the start of everything.

And that the interest Guest held for me was by no means a light one.
