Black Building

The Black Building (黒ビル, Kurobiru, Black Building) is a large multistory building, accessible through the large pink honeycomb wall in Onyx tile World.

Features
The lobby of the black building is mostly empty, featuring a Robot Guard at the front desk, two corridors off to each side and an elevator at the rear.

Through the corridor to the right is a lounge with 2 couches, and a pink creature relaxing on the left one.

To the left is a small room with a vending machine and a flight of stairs, allowing Urotsuki to travel between other levels of the building. On the very bottom floor there is a painting of a red spider lily, which transports you to the Art Gallery.

Going into the elevator will take you to an empty corridor with an office. Inside the office there is a cage with a Fairy inside, and a large purple stain on the floor in front of the Desk. Interacting with the cage will give you the Fairy effect.

If a certain switch is on [0042], the elevator has a 1/2 chance to instead take you to a conference room with 2 desks and another strange pink creature walking around.
