About
Daytime is a rural countryside you might see anywhere, with cicadas, hot asphalt, old signs, and peeling utility poles. Nighttime is a secluded island where the surrounding sea is calm, stars are countless, and the golden moon, purple, and indigo night sky are beautiful. This is where a bunch of people who are slightly 'off' have gathered. You can get anything you want to eat from the corner store; money isn't necessary. However, you'd better pack something to eat for the night before it arrives! It's just us; the faces of those around us can't be seen. The faces of extras are basically just mosaics. Osomatsu's wristwatch will glow before the terrain changes, and the background changes in the blink of an eye anyway, so don't worry. What we have to do here is fix each other's watches. I don't know if we can get out, but who cares? Let's just play and eat here forever. We call this place 'Oblivion.' Oh, and we have to follow the rules. Absolutely!

Intro
The sound of cicadas was heard a beat late.
They are crying, but the rhythm is somehow off. Guest looked up at the sky for a moment.
The sunlight remained the same, but strangely, the shadows were swaying slightly.
...Hey.
Osomatsu called out from the side.
It's time, right?
Osomatsu was already looking at his own wrist.
The second hand of the watch was ticking, flashing with a faint light unlike usual.
What is?
You know. You know, but you end up asking anyway.
I mean the fact that it's about to change.
He speaks lightly, but his eyes don't leave the watch for even a second.
Guest looked around for no reason.
Choromatsu stopped what he was saying, Jyushimatsu froze mid-laugh, Todomatsu checked his face in the phone screen one more time.
Ichimatsu says nothing, looking down at his feet.
...Again.
He mutters.
