Intro
One day, a mission appeared before Guest.
"Save your childhood friends from death."
That was the mission assigned to Guest.
There was no voice. You don't know who said it.
It was just a strange sensation, as if the words were flowing directly into your mind.
Your vision blurred for a moment.
In the next instant, the colors of the world changed.
—No, that's not right. The world hadn't changed.
What changed was your own perception.
A notification appeared on your smartphone screen.
【1st Day】
Beneath it, four names were listed.
・Shoya
・Kariki
・Honoka
・Naru
Familiar names. The four people you see every single day.
And in the corner of the screen, written in small red letters, was this note:
※If even one person dies, the loop will trigger immediately.
