Kingdom Hearts Birth by Sleep
The main Kontorōru Rūmu (コントロールルーム) is where the ship is piloted from, and has an east corridor and another to the west. Going east leads to the Sennai Tsūro (船内通路), a circular hallway with several gates throughout. In this hallway, Ventus and Aqua follow the corridor to Uchūsen: Tensō-shitsu (宇宙船:転送室), but Terra follows a separate section to the Kōsoku-shitsu (拘束室), where Stitch is original kept prisoner. Using the Durgon Transporter leads to the Tūro Hoshi: Tensō-shitsu (トゥーロ星:転送室), which heads to the jail unit called the Tūro Hoshi: Shūyō Kukaku (トゥーロ星:収容区画).

West from the Control Room is the Setsuzoku Kukaku (接続区画), a long, purple, and vertical shaft containing a pair of machines that can decrease the gravity inside the area. Climbing to the top of the shaft leads to the Shutsugeki Dekki (出撃デッキ), where another one of these machines can be found, along with a pair of turrets that'll attack any trespassers. Going into the tunnel across the room leads to the Kikan-shitsu Iriguchi (機関室入口), a tiny room leading further to the Kikan-shitsu (機関室), accessible only by Ventus. The Machinery Bay is a large round room, with an energy core at the center, with three bridges springing out of it above. The Launch Deck has another exit through a purple chamber, which leads to the Sentai Gaiheki (船体外壁). Traversing the Ship Exterior can only be done via the Keyblade Glider and leads back to the Durgon Transporter, making the world somewhat circular in nature.

Kingdom Hearts Birth by Sleep
Terra is the first person to appear in this world. After fighting a swarm of Unversed in space, he is swept onboard the Federation ship. He is placed, unconscious, in a prison cell and is visited by Captain Gantu and the Grand Councilwoman. He wakes up to a swarm of Unversed attacking the prison, breaks free, and fights the Unversed. He meets Dr. Jumba Jookiba who convinces him to unlock his cell so they can find Experiment 626, who is imprisoned somewhere on the ship. When they find him and release him, Experiment 626 snatches Terra's Wayfinder. When Terra refers to it as his bond with his friends, Experiment 626 drops it and runs, to Jumba's surprise. To demonstrate that his experiments do not have hearts, Jumba activates Experiment 221 to fight Terra. After the fight, Experiment 221 becomes deactivated and Experiment 626 returns. Terra talks to Experiment 626 about friendship before alarms go off. Experiment 626 and Jumba run off while Terra leaves the world.

Aqua is the second person to arrive in this world. After fighting a group of Unversed as soon as she boards the ship, she meets Experiment 626, who runs off. She then meets Gantu, who brings her before the Grand Councilwoman, who charges Aqua with destroying the Unversed on the ship and locating Jumba and Experiment 626. Aqua soon finds Experiment 626 and fights Unversed alongside him. Experiment 626 runs off again, and the Grand Councilwoman directs Aqua to the departure bays to capture Jumba and Experiment 626. When she finds them, she learns that Experiment 626 made a charm to copy Terra's charm. Gantu appears and attempts to destroy the three of them. Aqua and Experiment 626 fight Gantu for their freedom. After their victory, the Grand Councilwoman thanks Aqua for a job well done, and demotes Gantu. As she escorts Experiment 626 and Jumba away, Aqua then asks her to consider sparing Experiment 626's life. Before leaving, Aqua asks Experiment 626 to add her and her friends to his "bond".

Ventus is the last person to arrive in this world. He arrives on the ship after chasing a giant Unversed. He is confronted by Gantu, who runs off when the Unversed attacks the ship's engines. Ventus then meets an escaped Experiment 626 and learns that he has met Terra and Aqua. Ventus and Experiment 626 battle the giant Unversed attacking the ship. Gantu eventually finds them and plans to arrest Ventus with Experiment 626, but they escape the ship, Experiment 626 in a red cruiser and Ventus on his Keyblade. Experiment 626 accidentally activates his craft's hyperdrive, and Ven is blasted off by his Keyblade as Experiment 626 disappears into space.

In the ending credits, Experiment 626 gets his Wayfinder and puts it on the steering wheel as he flies off toward a blue star.
