Building Q in the Nevada Desert.

Building Q was a building related to the Nonary Game, being used in both the First and Second games. It was supposed to be a complete copy of the Gigantic, but it was located in the middle of the Nevada Desert.

Despite being a building in the middle of the desert, the interior of Building Q looks exactly like the Gigantic; thanks to a variety of features inside the building, most prominently rushing water that flows into it and sound effects that resemble the creak of a ship, a person placed inside Building Q would believe that they were on a ship in the ocean had they not known its true nature.

It is still unknown why the building is named "Building Q", but Q is a frequently recurring letter in the series.



The decks.

Building Q's interior was built as a copy of the Gigantic's. Due to this, the puzzles were exactly the same. Just like the Gigantic, Building Q had multiple decks connected by a Central Staircase.

A Deck

A Deck was the highest deck inside Building Q. Door 1 was located on the deck and led to the Chart room and the Captain's Quarters.

B Deck

B Deck was located just below A Deck and led to Door 4 and Door 5. The 2nd Class Cabin and Kitchen were located behind Door 4, while the 1st Class Cabin and Casino were located behind Door 5.

C Deck

C Deck was the location of the Hospital Room which held Door 3, Door 7, and Door 8. The Shower Room, Operating Room, and Laboratory were located behind the doors on C Deck.

D Deck

D Deck held the 3rd Class Cabin, and was flooded at the beginning of the Nonary Game.

E Deck

E Deck was located underneath D Deck, however it wasn't flooded. Door 6 was located on E Deck and led to the Steam Engine Room along with the Cargo Room.

Door 9 was also located on E Deck, and led to the Library, Study, and Incinerator, which was the location of Door q.

Bottom Deck

The Bottom Deck was the location of Door 2 and subsequently the Confinement Rooms and Torture Room.

First Nonary Game

Building Q was used by Cradle Pharmaceutical and Free the Soul for the First Nonary Game to put the kids in Group Q, who excelled at transmitting through the morphogenetic field, to transmit the answers to the puzzles to the kids in the Gigantic. Clover Field and Ennea Kashiwabara were in Building Q.

Due to a mix up regarding Akane Kurashiki, Akane was sent to the Gigantic instead of Building Q. To fill in Akane's missing role, there were two sisters in Building Q.

Nine Hours, Nine Persons, Nine Doors


The survivors realize they were in Building Q.

Building Q was later used by Crash Keys for the Second Nonary Game, as the Gigantic had been sunk in the previous Nonary Game. Its presence was only made known after the players of the game had escaped, as they had previously assumed they were on a ship because D Deck had been flooded.

After the survivors escaped from the building, they left in an SUV to track down their captors. On their journey, the group ran into Alice, who was attempting to get to Building Q after being tipped that the Myrmidons were stationed there. Alice joined the group in their pursuit but failed in reaching their detainers.
