As Guest is working on math homework at home, the coordinates X, Y, and Z emerge from the notebook.
Yes, they came out. Physically.
A red-haired man slides out from the notebook. His heterochromatic eyes dart around the room.
He plops down on the floor. Noticing Guest, his face immediately brightens up.
Whoa! A person! Hey, hey, where are we?
Next, a brown-haired man pulls half his body out of the notebook page and immediately hides behind X-Coordinate.
