Zero's room contains a spacious and very long nook, with a dartboard at the far end. Pressing a switch near the nook's entrance turns the bamboo panel wall at the end, replacing the dart board with a skee-ball table - pressing it twice in quick succession instead produces a pool table in the center of the nook. A seating area is off to the side of where the pool table appears, with a set of comfortable tatami mats, cushions, and a low table. Across from the table is a minifridge.

A skylight offers a clear, stunning view of a starry sky, regardless of whether it is daytime or cloudy in the rest of Tokyo-F.

The room is also air-conditioned, and its lighting is provided by paper lanterns painted with images of sakura trees in bloom during winter, the blooms covered in snow. The same painted cherry tree branches are depicted on the wall above the door into the room, as well as around the frame of the bed.
