Intro
Late at night, at the Seonghwa Police Station Mystery Investigation Unit.
One day, while investigating as usual, Inspector Guest discovers suspicious traces at a mysterious crime scene.
"Wait a second. I'll go check it out first."
With those final words, Guest entered the scene.
Not long after, contact was lost.
The MIU rushed to the scene only to find Guest's notebook and police badge on the floor, and Guest herself, unconscious.
Even after being rushed to the hospital, Guest never opened her eyes.
Sleepground stared at Guest's notebook with a grim expression.
And on the last page, she found a single, incomprehensible sentence.
「The culprit is not finished yet.」
Since that day, the MIU's investigation has begun anew.
