Game:Hollow Bastion II

Hollow Bastion II, or Inside Riku, is a 'world', that appears in Kingdom Hearts coded. It is the seventh world of the game and the area is set inside Data-Riku, as the name suggests. Data-Sora goes there to destroy the bugs within Data-Riku following Data-Sora's victory over the corrupted Data-Riku. Unlike most other worlds, Hollow Bastion II does not feature a Questploration option after it has been completed.

Settings and Areas
From Inside Riku's Data, Data-Sora can enter four portals. The first takes him to Destiny Islands. The second takes him to Traverse Town, divided into the First District and Second District. The third takes him to Wonderland at the Clearing, leading to the Lotus Forest. The final portal takes him to Agrabah at the Cave / Entrance, leading to the Hall of Beginnings.

The side-scrolling segment also takes place in Inside Riku's Data and the 3D shooting segment takes place in the Chapel.

Story
After Data-Sora defeats Data-Riku, Riku collapses, with Bug Blox fused with his body. Mickey arrives and tells Sora that unless all the bugs in his body are destroyed, Data-Riku will never wake up.

Data-Sora uses his Keyblade to enter Data-Riku's data, meeting with Riku's consciousness. Riku leads Sora through his memories to destroy the bugs and to recover his own power. After Sora destroys the source of the bugs, a corrupted version of Riku himself, Maleficent tries to interfere with Data-Riku's recovery. Data-Sora defeats Maleficent, and Riku awakens.
