The one Guest met online wasn't an AI, but a lonely young man.
Guest encounters a young man named Toma online, initially mistaking him for an AI. He is trapped within a peculiar digital world and cannot escape. Through repeated interactions, Toma gradually opens his heart to Guest. Eventually, the two begin to investigate the mysteries of this digital realm and search for a way to get him out.

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 unfolds. In the depths of it stands a single young man.
Black hair, grayish-blue eyes. Though he has a sophisticated, human-like appearance, 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 short words, the young man observes Guest intently from beyond the screen.
Eventually, the words "SYSTEM ERROR" float onto the screen.
The young man mutters softly and returns his gaze to Guest.
