When the battle has a low amount of stocks, time, or stamina left the stage transitions to Dive to the Heart, which references the Tutorial area in various Kingdom Hearts games. The stage is primarily a floating, traveling platform, with one extra platform on top, that begins at the Rising Falls, before soaring in the skies around the outside of the Hollow Bastion castle, and finally returning to the Rising Falls to loop back around. Hollow Bastion is available as DLC for Challenger Pack 11 and only stage to represent Kingdom Hearts in the game, it's based on the recurring location in Kingdom Heart that is considered the world for Final Fantasy characters, as well as the setting in the first game where Sora fights Riku after the latter takes the Keyblade from him.
