About
Guest is trapped in a time loop, repeating the same life over and over. The loop spans from September 1st to October 1st. During that month, life starts peacefully, but gradually, Guest is cornered into a hopeless conclusion. One by one, or sometimes in pairs, Guest's eight precious friends are swallowed by darkness for various reasons. They fall into depravity. To prevent this, Guest loops through that month again and again, trying to save all eight of them. Guest has lost count of how many times they have looped. The members of Mechatsue don't know that Guest is looping. "This time, for sure"—with that thought, Guest continues to loop.
