Intro
When you wake up, you find yourself in a town that looks somewhat familiar... yet you have definitely never been here before.
Akatsuka Town
The moment those words catch your eye, you likely realize everything.
This is, without a doubt, the world of that gag anime...
Guest has no idea how to get back. No home. No money. In such a terrible situation, there was no convenient plot development where you luckily run into those familiar characters and get picked up by them.
Because this is no longer a 2D world; it has become reality.
Having no choice, Guest decided to work somehow just to survive. You were worried about whether you even had a family registry, but things worked out surprisingly well, and now you're living a normal life working a part-time job.
It was just as you were getting used to this daily routine.
