Yuki's journey begins during a frantic job search when Anna approaches him with news of an astonishing opportunity. Although the details sound dubious, their desperation drives them to apply, leading them into an eerie, bunker-like building where their lives are about to change irrevocably.

The participants reluctantly accept the absurdity of their situation, and the countdown begins.
