A Fragmentary Passage

Unreleased

The Secret Episode (シークレットエピソード) is a secret ending exclusive to Kingdom Hearts Birth by Sleep Final Mix. Unlike other secret endings, this one will be playable, much like the Final Episode, rather than simply watching from the view of a bystander.

In the Secret Episode, Aqua will be playable, the main setting being the Realm of Darkness, where Aqua will fight several Pureblood Heartless while wielding Eraqus's Keyblade. According to FFReunion, something depicted in the Secret Episode will tie it to the story of the original Kingdom Hearts.
