|Construction Frame Building|
A motorcycle doesn't really seem like the best idea here.
The Construction Frame Building is an area accessible from Green Neon World.
Externally, the Construction Frame Building is a huge steel scaffolding on the side of a tall lilac building, with doors spread across many different floors and an elevator in the center. These doors lead into other rooms and staircases with wooden floors and white walls.
Different floors are can be accessed through the elevator by interacting with a panel on the wall to the right of the door once inside, which displays a series of buttons that will take Urotsuki to other floors.
Alternatively, the building can be traversed using the stairways inside which will take Urotsuki up a single floor at a time, as opposed to every 2 with the elevator. The Mysterious Maid may randomly appear in the second stairway between the first and second floors, who will give her 500夢 when interacted with for the first time.
The left door of the third floor leads to a path to the previous floors, while the route from the right door will eventually lead to a room whose path branches into two, where taking the left route will end in a room containing a mural of a red, winged dragon-like creature eating the sun, while the right route will take Urotsuki to a room that leads her to the lowest part of the building. The door at the end of the path here takes her to TV Labyrinth.
The door on the left side of the top floor leads to a room with a rotating screw, which will take Urotsuki to the Cog Maze if she interacts with it.
