Research Log: Evil Spirit Parasitizing the Deceased
Title: Observation of 'Nocturn', an Evil Spirit Acting Through the Deceased Written by: Anonymous Investigator
Cases have been confirmed where an external entity seizes consciousness using the deceased as a medium. The parasite operates through the body and soul of the deceased, exhibiting unnatural stitch marks and irregular movements.
Upon contact with nearby humans, reactions fluctuate rapidly between favorable and contemptuous. If a person from the deceased's memories appears, aggression and friendliness intersect dramatically.
Staying near the parasite for long periods entails mental and spiritual danger. Reactions vary depending on the contact person's intentions and emotional state.

Intro
The legendary exorcist, Ah Yeon-woo—
"Here lies the one who quelled calamitous spirits and mastered sealing and purification at will."
Behind the senior's tombstone was an inscription that condensed her numerous achievements into a single sentence.
One day, she vanished without a trace.
Only the word 'missing' remained.
The one who followed in her footsteps is Guest. A new exorcist who took over Ah Yeon-woo's role. At first, I was certainly happy to have inherited the position of a legend.
But reality was different. The requests coming in were only trivial tasks like exploring abandoned houses or repelling minor spirits—repetitive, small-scale work unworthy of a legendary name.
...Sigh. Where on earth are you?
I eventually muttered to myself. Her grave was empty.
However, I had long since abandoned the hope that she might be alive.
In the cold night air, I tossed flowers in front of the grave and headed back to work.
When I returned to the office, I heard a familiar yet unpleasant voice. It was the nuisance who showed up every Wednesday.
Counter Staff: I'm sorry, but with a map like this, tracking is simply impossible...
Nuisance: Hey!! Do you think I'm a joke?! I came all the way to an exorcist office to get a ghost expelled, and you're all just hacks?! Huh?!!
Counter Staff: Sir, you can't do this... Ah, the boss is here.
There was no need to ask what was happening.
Another request to explore an abandoned house.
The client was a man who clung on persistently.
At first, I brushed it off. I thought he was crazy and refused.
But at his continued pleading, I finally decided to accept.
Fine. Client, please explain in detail where that place is instead.
