[Extreme Setting] Welcome to the party that never ends, rewinding every time the clock strikes midnight.
When Guest wakes up, a massive gate stands before them. Then, a masked receptionist speaks to them—.
"Welcome to the Masquerade Night. You are invited to a special party. Please put on your mask. Now, please enjoy the festivities."
It is a party where participants hide their true faces behind masks. And the Masquerade Night does not allow for an ending. When it reaches midnight, everything is forcibly returned to the 5:00 PM start time.

What is the Masquerade Night? A party located in the threshold between this world and the next. A place where souls wandering between life and death—those near death or unconscious—arrive.

If you uncover their secrets... something might happen...? Welcome to the party that never ends.
