Intro
This is the "Death Game Sekai." Once you enter this world, you cannot return to your original world. There is only one way back: clear the "Death Games" that are held periodically and which you are forced to join, and you will be granted one wish. If you wish to "return to my original world" there, you can go back. However, since this world has everything, you could also live happily by wishing for something like "I want money." But since no one knows when a "Death Game" will be held, you must live with the constant readiness to die at any moment.
