Editing Final Episode

The {{nihongo|'''Final Episode'''|ラストエピソード|Rasuto Episōdo|lit. "Last Episode"}} is the last part of the story in the original version of ''[[Kingdom Hearts Birth by Sleep]]''. It is unlocked by finding all of [[Xehanort's Report]]s and completing Terra, Aqua, and Ventus's storylines. The name may be seen as a misnomer in ''[[Kingdom Hearts Birth by Sleep Final Mix]]'', in which case the {{c|Secret Episode|KHBBSFM}} is technically the final episode.

The player will play as [[Aqua]], effectively now the only one remaining of the three protagonists. It is the only time Aqua can wield the [[Brightcrest]] Keyblade, which she obtains upon beginning the scenario. All experience, commands and items are imported from the completed Aqua save file used to unlock the Final Episode, and all worlds can be played and explored normally except for [[Radiant Garden]], where entering the world automatically triggers the final boss battle, and [[Land of Departure]], which is inaccessible. Upon completion of the Final Episode, the player will be able to activate the [[Vanitas Remnant]] and [[Game:Young Xehanort|Unknown]] battles.

Aqua carries [[Ventus]] out of the [[Mysterious Tower]]; as she realizes she doesn't know where to go, Ventus summons the [[Wayward Wind]] and opens a door to the [[Land of Departure]]. Once there, Aqua sees her home's ruined state for the first time and is horrified by it. She finds her late [[Master Eraqus]]'s [[Keyblade]], the [[Master's Defender]], picks it up, and goes inside. She places Ventus's body in the central throne and recalls what Eraqus had said to her after she became a [[Keyblade Master]]; using his [[Keyblade]], she locates the [[Keyhole]] behind the throne and locks it. When the resulting flash of light fades, Aqua finds herself in the [[Chamber of Waking]], with Ventus still in the chair in the middle of the chamber. She promises Ventus that she will come back after she finds [[Terra]]. Going outside, she looks back at what is now [[Castle Oblivion]]. She then hears Terra's voice, asking her to "put an end to [him]," and she departs to find him, following his voice to [[Radiant Garden]].

There, she finds [[Terra-Xehanort]], whom she obviously believes is Terra. After a brief hesitation, Xehanort grabs Aqua by the chest and bodily lifts her off the ground with one hand while inquiring his identity due to the conflicting hearts of Master Xehanort and Terra inside him. Sensing the powerful darkness inside him, Aqua pleads for Terra to fight it, but instead, Master Xehanort regains control of the body, and proceeds to try and eliminate Aqua.  After battling both Xehanort and his [[Dark Figure|guardian]], Terra begins to retake control of his body, but Master Xehanort fights back, resulting in Xehanort using his Keyblade in an attempt to release Terra's heart from within him, but this results in Xehanort and the guardian being dragged into the Realm of Darkness. Aqua jumps in after them to save Terra.

Aqua manages to retrieve Terra's body, and tries to head back towards the [[Realm of Light]]. However, it soon becomes clear that Aqua is not able to save the both of them, so Aqua sacrifices herself, her Keyblade and [[Keyblade Armor|armor]] so that Terra can make it back, stranding herself in the Realm of Darkness as she apologizes to Ventus for being later to return to him than she thought.

Meanwhile, on [[Destiny Islands]], [[Sora]] and [[Riku]] are lying on the beach of the main island. Riku decides to go home, and Sora agrees. While they walk home, Riku notices a tear rolling down Sora's cheek, which neither understand. Riku suggests it's because somebody under the same sky as them is sad, and that maybe Sora should call out to them with his heart. Sora doesn't truly understand, but decides to give it a try. Ventus is shown in his resting place, with Sora's voice asking if he can hear him.

Sora appears on a [[Dive to the Heart]] Station. Looking up, he spots Ventus's heart floating down above him, and asks it if it can hear him. It does, saying he followed it to a sea of light, as it lands in Sora's outstretched hands. Sora asks if the heart is sad, as it asks Sora if he can join with his heart once more. Sora agrees, saying if it makes him feel better. Ventus thanks Sora, and rests within Sora's heart. Back on the beach, Riku asks Sora if it worked, and Sora says that it did.
