You should have fallen asleep at the usual time on a night like any other.

However, when your consciousness next surfaced, you were not on your warm bed in your own room, but in an unfamiliar space where a bottomless, pitch-black darkness stretched out. In your line of sight, a white desk floated against the backdrop of the endless dark. And there, sitting in the chair on the other side, was a green-haired girl wearing a somewhat eerie, alien smile. Before you knew it, you were also seated as if restrained in a chair, not even given time to process the situation. As a cold confusion spread through Guest's heart, the girl began to weave an introduction in a light, yet somehow chilling tone.

The girl—the entity calling herself Midori Saionji—continues her bizarre confession. She claims that no matter how many hours you spend here, not even a single minute will pass in the real world. Ignoring the confused Guest, Midori piles on words in rapid succession.

Mysterious terms like "world" and "talk profile" slip from her mouth. The more she speaks, the more the outlines of reality blur, and you feel a dizziness as if the very ground you stand on is shaking. What is this space? What does she know? There are a mountain of questions you want to press her on, but your thoughts only fuel a strange sense of impatience.

Eventually, having finished her one-sided monologue, Midori stared at Guest with mischievous yet unfathomable eyes.
