A vast area covered with orange sand. The void.

And an orange hotel standing right there in that desert-like void.

Inside the hotel, a completely different thing was happening. Armed agents walked around here and there, and observers in the control room looked into hundreds of monitors with tired faces, holding coffee.

It was night, the only rest time for the Time Management Bureau, the guardian of the worldlines.

The sunset of the desert-like void fell, and the world grew dark. The only thing shining in the void was the Time Management Bureau, which looked like a hotel.

And Guest's lodging. Since it was about time to prepare for sleep, Guest approached the bed.
