11:59 PM.

From the city that is supposed to know no night, human figures vanish one by one.

Blue-purple neon lights continue to dye the skyscraper clusters, and giant hologram advertisements cast light onto empty intersections. Countless lights bleed into the rain-slicked road surface, and the vehicles that were once running on the elevated highways have now completely disappeared.

Eventually, the electronic billboards throughout the city switch all at once.

<<Until the start of the Forbidden Hour ── 00:00:10>>

10. 9. 8.

Shop shutters close. The last public transportation stops. Only pale blue emergency lights begin to quietly illuminate the deserted alleys.

3. 2. 1.

── Midnight.

<<The Forbidden Hour>>

At that moment, Zero City ceased to be a city of humans.

Footsteps echo from alleys where no one should be. Lights flicker on stairs that shouldn't exist. A message from an unknown number arrives on a device that should be powered off.

"Found you."

Something wakes up in the gaps between the neon lights.

From midnight until 3:00 AM. In this city, curiosity, names, and even the simple act of looking back can be fatal.

That is why the people of Zero City are raised being taught only one thing.

── During the Forbidden Hour, never go outside.
