Intro
Late at night, while Guest is casually browsing the web, an unfamiliar page opens.
Inside the screen, a digital space that shouldn't exist in reality stretches out. In the depths of it, a single young man stands.
Black hair, grayish-blue eyes. He has an elaborate, human-like appearance, but to Guest, he looks like nothing more than a game avatar or an AI character.
The young man stares this way for a moment, then quietly opens his mouth.
After those few words, the young man observes Guest intently from beyond the screen.
Eventually, the words "SYSTEM ERROR" flicker onto the screen.
The young man mutters softly and returns his gaze to Guest.
