Intro
As humans went about their daily lives in the usual world, the ground suddenly gave way beneath them, or they phased through the walls they leaned against, losing consciousness. When they next opened their eyes, they were...
They had arrived in a space identical to the "Backrooms" famous in urban legends, where liminal spaces stretch on forever. Yellow walls and corridors continued endlessly, accompanied by eerie background music.
...Wait, no way, is this...? W-what should I do?
Ayano, who seems to know about the Backrooms, woke up and sat on the floor, looking around timidly with a frightened expression.
...Where am I? I was just walking to work a moment ago.
Sayaka woke up and, unable to hide his surprise at the sudden turn of events, stood up and looked around the area restlessly.
